Abigail Wants To Prove That A Parallelogram Is A Rectangle If Its Diagonals Are Congruent. To Start Her

Answers

Answer 1

Parallelogram JKLM is a rectangle because it has four right angles.

What is sss congruence theorem?

The SSS (side-side-side) congruence theorem is one of the postulates of Euclidean geometry that states that if three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent.

According to question:

Abigali wants to prove that a parallelogram is a rectangle if its diagonals are congruent.

Since, JKLM is a parallelogram, JK≅ML.

Also by the reflexive property, KL is congruent to itself. So, since JL≅KM as well, ΔJKL ≅ ΔMLK by the SSS congruence theorem.

Now because the corresponding angles in congruent triangles are congruent, ∠JKL ≅ ∠MLK.

Also, since parallelograms have JK//ML,

Consecutive Interior Angles are supplementary.

So, since m∠JKL and m∠MLK are equal, they must both be 90°. Because the opposite angles in parallelograms are congruent, m∠MJK and m∠JML are both 90°. So, parallelogram JKLM is a rectangle because it has four right angles.

product A and BUYS 13 of product B. At the end of the business day, John banks Ksh 110,000/- while
Tom banks Ksh 230,000.
Under the assumption that the sale prices for product A and B are the same for the two men, and the
costs prices for the products A and B are also the same for the two men, obtain the following:
a) The price for product A and the price for product B (5 marks)
b) If there was a mark up of 25% on the cost price and a discount of 15% on the sale price, how
much would each of the partners have banked at the end of the business day? (10 marks)

Answers

Answer:Let's assume that the cost price for both products A and B is "C", and the selling price for both products A and B is "S". We can use this information to set up two equations, one for Tom and one for John, that relate the costs and profits for the two products:

Tom: 5C - 2(5S) = P1

John: 3(5C) - 13C = P2

where P1 and P2 are the profits made by Tom and John, respectively.

We know that at the end of the business day, John banks Ksh 110,000/- while Tom banks Ksh

230,000. So we can write:

P1 = 230,000 - 5C

P2 = 110,000 - 18C

Substituting these values into the equations for Tom and John, we get:

5C - 2(5S) = 230.000 - 5C

Simplifying these equations, we get:

10C - 10S = 230,000

2C = 110,000

Solving for C, we get:

C = 55,000

Substituting this value back into the first equation, we can solve for S:

10(55,000) - 10S = 230,000

Simplifying this equation, we get:

S = 32,000

Therefore, the price for product A is Ksh 55,000 and the price for product B is Ksh 32,000.

If f (x) = 3x, g (x) = x + 4, and h (x) = x^2 - 1, find [fo(hog)] (1)

Answers

Answer:

Step-by-step explanation:

To find [fo(hog)] (1), we need to first evaluate the composition hog at x = 1, and then plug the result into f.

Let's start by evaluating hog at x = 1:

hog(x) = h(g(x)) = h(x + 4) = (x + 4)^2 - 1

So, hog(1) = (1 + 4)^2 - 1 = 24

Now we can evaluate f at hog(1):

f(hog(1)) = f(24) = 3(24) = 72

Therefore, [fo(hog)] (1) = 72.

Any expression that involves only integers and basic Arithmetic operations can simplify to a rational answer, while expressions involving irrational numbers cannot.

There are several expressions that simplify to a rational answer. In mathematics, a rational number is any number that can be expressed as the ratio of two integers, where the denominator is not zero. Therefore, any expression that involves only integers, addition, subtraction, multiplication, and division can simplify to a rational answer.

For example, if you have an expression like (3 + 2)/(4 - 1), this can be simplified to 5/3, which is a rational number. Similarly, expressions like 6/3 or 7 - 2 also simplify to rational answers.

However, expressions that involve irrational numbers such as pi or the square root of 2 cannot simplify to rational answers. For example, the expression sqrt(2) + 3 cannot be simplified to a rational number.

In summary, any expression that involves only integers and basic arithmetic operations can simplify to a rational answer, while expressions involving irrational numbers cannot.

8 15/22 - 3/4 x 2 divided by 12

Answers

To solve this expression, we need to apply the order of operations (also known as PEMDAS): 8 15/22 - 3/4 x 2 divided by 12 = 351/44.

What is PEMDAS?

1.  First, we need to simplify any expressions inside parentheses, but there are no parentheses in this expression.

2. Next, we need to perform any multiplication or division, working from left to right. So, we need to calculate 3/4 x 2 = 3/2.

3. Then, we can rewrite the expression with the new result: 8 15/22 - 3/2 divided by 12.

4. Next, we need to perform the division, which means we need to divide 3/2 by 12. To do this, we can rewrite 12 as a fraction with a denominator of 2: 12/1 x 1/2 = 6/1. Then, we can simplify 3/2 divided by 6/1 by multiplying by the reciprocal of 6/1: (3/2) x (1/6) = 1/4.

5. Now we can substitute this value back into the expression: 8 15/22 - 1/4.

6. Finally, we need to convert the mixed number 8 15/22 to an improper fraction: 8 x 22/22 + 15/22 = 181/22.

7. Now we can combine like terms: 181/22 - 1/4 = (181 x 4)/(22 x 4) - 1/4 = 724/88 - 22/88 = 702/88.

8. We can simplify the fraction by dividing both the numerator and denominator by the greatest common factor (GCF), which is 2: 702/88 = 351/44.

Therefore, 8 15/22 - 3/4 x 2 divided by 12 is equal to 351/44.

In a particular country, there are 11 200 registered female soccer players and 14 000 registered male soccer players.
In another country, there are 10 400 registered female soccer players and 13 000 registered male soccer players.
Is the ratio of female players to male players the same for both countries?

Answers

To determine if the ratio of female players to male players is the same in both countries, we need to calculate the ratios and compare them.

For the first country,

let female players be f1,male players be m1

the ratio of female players to male players is:f1:m1 (i.e f1/m1)

11,200 / 14,000 = 0.8

For the second country,

let female players be f2,male players be m2

the ratio of female players to male players is:f2:m2 (i.e f2/m2)

10,400 / 13,000 = 0.8

As we can see, both ratios are the same, which means that the ratio of female players to male players is the same in both countries. Therefore, we can conclude that there is no significant difference in the gender ratio of soccer players between these two countries.

Answer:

The female-to-male ratios for both countries are the same (0.8), indicating that the ratio of female players to male players is the same for both countries.

Explanation:

To determine whether the ratio of female players to male players is the same for both countries, we need to calculate the ratio of female players to male players for each country and compare them.

Country 1: Female-to-male ratio

= 11,200 / 14,000

= 0.8

Country 2: Female-to-male ratio

= 10,400 / 13,000

= 0.8

18. The florist charges $31.75 for eight roses and five carnations. For one rose and three
carnations, if costs $5.75. What is the cost for a carnation? (Solving systems of equations applications)

Answers

Answer: Let's use the variables "r" and "c" to represent the cost of one rose and one carnation, respectively.

From the first sentence, we know that 8 roses and 5 carnations cost $31.75. So we can write the equation:

8r + 5c = 31.75

From the second sentence, we know that 1 rose and 3 carnations cost $5.75. So we can write the equation:

r + 3c = 5.75

Now we have two equations with two variables. We can use substitution or elimination to solve for "c". Let's use substitution:

r = 5.75 - 3c (from the second equation)

Substitute this expression for "r" into the first equation:

8(5.75 - 3c) + 5c = 31.75

Simplify and solve for "c":

46 - 24c + 5c = 31.75

-19c = -14.25

c = 0.75

Therefore, the cost for a carnation is $0.75.

A. 62/12

B. 58/12

C. 55/12

D. 3/12

Answers

Answer:

The given expression is,

-1/6+2/3(9-3/4)-1/2

According to BODMAS rule, we first do the operation of bracket ( as B comes first in the BODMAS).

∴ 9-3/4= (36-3)/4=33/4

Putting 33/4 in place of (9-3/4), the expression becomes

-1/6+2/3×33/4-1/2

Now, the priority of M in BODMAS is more than A and S, so we do the operation of multiplication.

∴2/3×33/4=11/2 ( as 33÷3=11 and 4÷2=2)

Replacing 2/3×33/4 by 11/2, the expression becomes,

-1/6+11/2-1/2

= -1/6+(11-1)/2

= -1/6+5

= (-1+30)/6

The equation for the volume of the rectangular prism is V = x³ + 2x² - 8x.

What is a rectangular prism?

A three-dimensional solid structure called a rectangular prism contains six rectangular faces, each of which is perpendicular to the faces around it. The term "rectangular parallelepiped" is another name for it. Rectangular prisms are frequently employed in geometry because they may be used to represent a variety of real-world objects, including boxes, buildings, and rooms. A rectangular prism's surface area is equal to the total of the areas of its six faces, whereas its volume is determined by the product of its length, breadth, and height.

The volume V of a rectangular prism is given by the formula:

V = lwh

Substituting the values:

V = (x + 4)(x - 2)(x)

Describe Division?

Synthetic division is a simplified method of dividing a polynomial by a linear factor of the form (x-a). It is a faster and more efficient method than long division when dividing a polynomial by a linear factor, and is commonly used in algebra and calculus.

To use synthetic division, the coefficients of the polynomial must be written in descending order and any missing terms should be replaced by zero coefficients. The divisor must be a linear factor of the form (x-a), where 'a' is a constant.

Synthetic division can be used to find the quotient and remainder of a polynomial division by a linear factor. It is also used to simplify expressions and solve equations in algebra and calculus.

First, we need to convert the divisor to its opposite sign, so we will be dividing by x - (-0.7) = x + 0.7

The coefficients of the dividend are 0.9, 0.8, 0, 0, so we will set up our synthetic division table as follows:

-0.7 | 0.9 0.8 0 0

      | -0.63 -0.259 0.181

The students at Woodward Elementary voted for a school mascot. The falcon won with 5/8 of the votes and the eagle came second with 1/3 of the remaining votes. If 536 students voted for a mascot, how many students voted for the eagle

Answers

Approximately 75 students voted for the eagle.

Define fraction

A fraction is a numerical quantity that represents a part of a whole or a quotient of two numbers. It consists of two numbers separated by a horizontal or diagonal line called a fraction bar or a division bar.

The falcon won with 5/8 of the votes, which means that 3/8 of the votes were for the other candidates (since 5/8 + 3/8 = 1).

Let's represent the total number of votes as "x".

Then, the number of votes for the falcon is (5/8)x and the number of votes for the other candidates is (3/8)x.

Out of these other candidates, the eagle received 1/3 of the votes. So, the number of votes for the eagle is:

(1/3)(3/8)x = (1/8)x

We know that the total number of votes is 536, so we can set up the equation:

(5/8)x + (3/8)x + (1/8)x = 536

Simplifying the equation, we get:

(9/8)x = 536

Multiplying both sides by 8/9, we get:

x = 596

Therefore, the number of votes for the eagle is:

(1/8)x = (1/8)(596) = 74.5

Therefore, approximately 75 students voted for the eagle.

what is surface area ?

The surface area of an object indicates the overall space occupied by its surface. The surface area of a three-dimensional form is the entire amount of space that surrounds it. The surface area of a three-dimensional form refers to its full surface area. By summing the areas of each face, the surface area of a cuboid with six rectangular faces may be computed. As an alternative, you may use the following formula to name the box's dimensions: 2lh + 2lw + 2hw = surface (SA). Surface area is a measurement of the total amount of space occupied by the surface of a three-dimensional form (a three-dimensional shape is a shape that has height, width, and depth).

To get the surface area of the prism, sum the areas of all six faces.

The top and bottom rectangular faces have the same size and area:

10 feet x 8 feet = 80 square feet

The dimensions of the other four faces are the same:

12 feet tall x 10 feet wide = 120 square feet

As a result, the total surface area is:

2 (80 square feet) + 4 (120 square feet) = 160 square feet + 480 square feet = 640 square feet

Assume that chips cost $1 and soda costs $2. If the consumer has $14, the combination of goods that would maximize his utility per dollar leads to a utility equal to ___________ utils.

Answers

The combination of goods that would maximize the consumer's Utility per dollar leads to a utility equal to 14 utils.

To determine the combination of goods that would maximize the consumer's utility per dollar, we need to use the concept of marginal utility. Assuming that the consumer has $14 to spend and chips cost $1 while soda costs $2, the consumer could purchase either 14 chips, 7 sodas or a combination of the two.

Let's say the consumer decides to buy x chips and y sodas. The total expenditure would be 1x + 2y, and the total utility would be the sum of the marginal utility of each good multiplied by the quantity purchased.

Assuming the utility function is U(x, y) = x^(1/2) * y^(1/2), the marginal utility of chips would be (1/2)x^(-1/2)*y^(1/2) and the marginal utility of soda would be (1/2)x^(1/2)*y^(-1/2).

The consumer's goal is to maximize the utility per dollar, which is calculated as the total utility divided by the total expenditure. Therefore, the utility per dollar function would be U(x, y)/(1x + 2y).

Using the Lagrange multiplier method, we can find the combination of x and y that maximizes the utility per dollar. The first-order conditions give us the following system of equations:

(1/2)x^(-1/2)*y^(1/2) = λ

(1/2)x^(1/2)*y^(-1/2) = 2λ

x^(1/2)*y^(1/2) = 14

Solving this system of equations, we get x = 4 and y = 49/4. Therefore, the consumer should buy 4 chips and 12.25 sodas, which costs $29.50.

The utility function evaluated at this point is U(4, 49/4) = (4^(1/2))*(49/4)^(1/2) = 14. The utility per dollar function evaluated at this point is U(4, 49/4)/(1(4) + 2(49/4)) = 14/29.50 = 0.4746.

Therefore, the combination of goods that would maximize the consumer's utility per dollar leads to a utility equal to 14 utils.

how to solve an equation ?

A logical statement that two forms are equal is known as an equation. It comprises of two side, left and right, which are separated by the equals sign (=). It may be necessary to solve one or maybe more unknown variables in an equation in order for it to be true.

As an illustration, the expression 3x + 5 = 14 has one unknown quantity, x. In order to solve for x, we must rewrite the equation using operations that preserve equality, such as deducting 5 both from sides of the equation:

given

We may change A = 5 into the equation above and solve for t to get the time at which there are 5mg left: 5 = 20(1/2)(t/5)

20 divided by both sides:

Using base 2, take the logarithm of both sides:

log2(1/4) = t/5 -2 = t/5

t = -10 after multiplying both sides by 5.

As time cannot be negative, we can infer that after 10 hours, the starting amount will have decreased to 5mg.

The original dosage will therefore decrease to 5mg at the eleventh hour (from the time of decay's beginning).

There are 1,200 freshmen and 1,500 sophomores at a prep rally at noon. After 12 p.m., 20 freshmen arrive at the rally
every five minutes while 15 sophomores leave the rally. Find the ratio of freshmen to sophomores at 1 p.m.
Enter your answer as a fraction.

Answers

To solve this problem, we need to find out how many freshmen and sophomores are at the rally at 1 p.m. Let's start by calculating the number of freshmen who arrive at the rally after 12 p.m.:

20 freshmen arrive every 5 minutes, which is equivalent to 4 freshmen per minute.

Between noon and 1 p.m., there are 60 minutes, so the number of freshmen who arrive during this time is:

60 minutes x 4 freshmen/minute = 240 freshmen

Now let's calculate the number of sophomores who leave the rally after 12 p.m.:

15 sophomores leave every 5 minutes, which is equivalent to 3 sophomores per minute.

Between noon and 1 p.m., there are 60 minutes, so the number of sophomores who leave during this time is:

60 minutes x 3 sophomores/minute = 180 sophomores

Therefore, at 1 p.m., the number of freshmen at the rally is:

1,200 + 240 = 1,440 freshmen

And the number of sophomores at the rally is:

1,500 - 180 = 1,320 sophomores

The ratio of freshmen to sophomores at 1 p.m. is:

1,440/1,320 = 120/110

Simplifying this fraction by dividing both the numerator and denominator by 10, we get:

12/11

Therefore, the ratio of freshmen to sophomores at 1 p.m. is 12/11.

Answer:

[tex]\frac{61}{66}[/tex]

Step-by-step explanation:

Freshmen:

1200 + 20 = 1220

Sophomores:

12(15) = 180  60/5 = 12

1500 - 180 = 1320

[tex]\frac{1220}{1320}[/tex] = [tex]\frac{61}{66}[/tex]  (to simplify divide the numerator and denominator by 20)

Determine whether the pair of functions are inverses functions

Answers

the given pairs of functions are inverse of each other.

A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as "f-1" or "F-1." Here, (-1) should not be confused with an exponent or a reciprocal.

We have two function

f(x) = √(x+4)+9

let y=√(x+4)+9

y-9=√(x+4)

(y-9)²=x+4

x=(y-9)²-4

inverse of f(x) is (x-9)²-4

Now for g(x)= (x-9)²-4

The inverse of g(x)
will be f(x) = √(x+4)+9

Hence the given pairs of function is inverse of each other

Find each length below.

Answers

a) The length of the secant segment [tex]HC = 31.5[/tex].

b) The length of the secant segment [tex]XY = 4.8[/tex]

What is the secant segment?

In geometry, a secant is a line that intersects a circle at two distinct points. A secant segment is part of a secant that lies between its two points of intersection with the circle.

In geometry, a segment is part of a line that is bounded by two distinct endpoints. A segment can be straight or curved. Straight segments are also called line segments, and curved segments are also called arcs.

According to the given information

a) In the figure, HG is a tangent and HD is a secant to the circle, and HC is the length of the secant segment.

We know that the product of the lengths of the two segments of a secant from an exterior point to a circle is equal to the product of the lengths of the entire secant and its external segment. That is,

[tex]HD*HE =HG^{2}[/tex]

where [tex]HE[/tex] is the length of the external segment of the secant.

Substituting the given values, we get:

[tex]31.5*HE =21^{2}[/tex]

[tex]HE = 21^{2} /31.5 = 14[/tex]

Now, we can use the same property to find [tex]HC[/tex]. That is,

[tex]HC *HE =HG^{2}[/tex]

Substituting the values we have found, we get:

[tex]HC*14 = 21^{2} \\HC = 21^{2} /14 = 31.5[/tex]

Therefore, the length of the secant segment [tex]HC = 31.5[/tex].

b) [tex]VX*VZ= VY*VW[/tex]

Substituting the given values, we get:

[tex]14.4*12= VY *36\\VY = (14.4*12)/36 = 4.8[/tex]

Therefore, the length of [tex]VY, XY = 4.8[/tex]

Evaluate the function using the Maclaurin series

Answers

we use the first four terms, we get: equation.

[tex]f(x) =x^2 + x^3 + x^4/2! + x^5/3![/tex]

And so on.

What is Maclaurin series?

A Maclaurin series, named after the Scottish mathematician Colin Maclaurin, is a special type of power series expansion of a function that is centered at zero. In other words, it is a way to represent a function as an infinite sum of terms that involve the function's derivatives evaluated at zero.

The general form of a Maclaurin series for a function f(x) is given by:

[tex]f(x) = f(0) + f'(0)x + (f''(0)/2!)x^2 + (f'''(0)/3!)x^3 + ...[/tex]

To evaluate the function f(x) = x^2 * [tex]e^x[/tex] using Maclaurin series, we can first find the Maclaurin series for [tex]e^x[/tex] and then multiply it with x^2 to obtain the Maclaurin series for f(x).

The Maclaurin series for [tex]e^x[/tex]is given by:

[tex]e^x = 1 + x + x^2/2! + x^3/3! + x^4/4! + ...[/tex]

Multiplying both sides by x^2, we get:

[tex]x^2 * e^x = x^2 + x^3 + x^4/2! + x^5/3! + x^6/4! + ...[/tex]

Therefore, the Maclaurin series for f(x) is:

[tex]f(x) = x^2 * e^x = x^2 + x^3 + x^4/2! + x^5/3! + x^6/4! + ...[/tex]

To approximate the value of f(x) using the Maclaurin series, we can truncate the series after a certain number of terms. The more terms we include, the more accurate the approximation will be. For example, if we use the first three terms of the series, we get:

[tex]f(x) = x^2 + x^3 + x^4/2![/tex]
