Answers

Answer 1

Answer:

B) x² + 5x + 19

Step-by-step explanation:

(2x² + 7x + 10) - (x² + 2x - 9)

==> remove parenthesis and apply negative sign

2x² + 7x + 10 - x² - 2x + 9

==> combine like terms

x² + 5x + 19

the answer is B

Important Note:

Like terms are terms with the same variable and exponent. Eg. 5x³ and x³ are like terms because they both have a common variable x, and a power of 3.

Answer 2

Answer:

B)  [tex]x^2+5x+19[/tex]

Step-by-step explanation:

I need help pls for this

Answers

Solution :

According to the question,

Time taken by Jesse to run 1 mile = 7 minutes

Also,

Time taken by Jesse to run 1 mile = 2½ minutes + Michael's time [tex]\;[/tex]

Now, we can say that :

7 minutes = 2½ minutes + Michael's time

⇒ (7 - 2½) minutes = Michael's time

⇒ (7 - 5/2) minutes = Michael's time

⇒ (14 - 5)/2 minutes = Michael's time

⇒ 9/2 minutes = Michael's time

4½ minutes = Michael's time [Answer]

Step-by-step explanation:

Question:-In track practice, Jesse ran a mile in 7 minutes. His mile time was2.5 minutes faster than Michael's time. Write and solve an equation to calculate Michael's mile time.

Solution

Jessie time 7 minute

Michael’s time is 2.5 times slower

Divide 7 minutes by 2.5 to get answer

Jesse = 7

Michael = 2.5 X

7 = 2.5 X

7/2.5 X = 17.5 to check answer divide 17.5 by the 2.5, your answer is 7.

Or if it was 2.5 more

we subtract 2.5 from 7

=> 7 - 2.5

=> 4.5

=> 4 ½

A function assigns values. The difference between the maximum value of g(x) and the minimum value of f(x) is 18.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

Since the maximum of the parabola function g(x) will lie at its vertex, therefore, the maximum will be at (3,12). Now, if we try to find the minimum of the function f(x). We need to plot the function on the graph as shown below.

As the minimum of the function f(x) will lie at the vertex of the parabola function, therefore the minimum of the function f(x) will lie at (3,-6).

If we try to find the difference between the maximum value of g(x) and the minimum value of f(x), then we will get,

[tex]\rm Difference=12-(-6)=18[/tex]

Thus, the difference between the maximum value of g(x) and the minimum value of f(x) is 18.

Julie wants to randomly choose two out of three friends, Margarite, Anita, and Sasha, to go with her to a

concert. In which method does one of Julie's friends have more than a fair chance of being chosen?

Answers

Slip system can be used to give more than fair chances of selection where the number of slips for one is more than the other.

There are multiple ways of selecting random sample like tossing a coin, flipping a die, lottery system.

Describing a method which can be used to provide more than a fair chance of selection is as follows:

Julie has 3 friends, so make the total number of slips say n

where n is not a multiple of 3.  

If n is not a multiple of 3 then her 3 friends will not get an equal chance of being selected.

Consider n=5

She has 3 friends, so 2 slips has repeated names, thus creating more chance of being selected than the one who has name only on one slip.

Thus, this method may result in more chance of selection of one over other.

The label on a can starts 2.5 in below the lid. What
is the area of the label?

Answers

From the computation below, the area of the label is 707 Inches.

This calculation is carried out using the theorem of the area of curved shapes.

What is the Curved Surface Area of a Cylinder?

The formula for the Curved Surface Area of a Cylinder is given as:

                                               2 [tex]\pi[/tex] rh

                                              =  2 [tex]\pi[/tex] x 7.5 x 15.

This assumes that the label also ends at an equal distance from the top of the lid.  Hence 15in = 20 - (2.5 x2);

Recall that [tex]\pi[/tex] =  22/7, hence

= 2 x (22/7) x  7.5 x 15

= 707.142857143

Approximately, this equals; 707 Inches.

Hence, the area of the label = 707 inches.

Notice that the question is incomplete. From inference, however, the general calculation above contains the principles for calculating the area of a label.

Which is the equation of a circle whose center is at the origin and that passes through the point (3, 5)?

Answers

Answer:

x² + y² = 34

Formula:

(x - h)² + (y - k)² = r²                    where (h, k) is the center

Here find the radius using distance formula:                → origin : (0, 0)

√(x2-x1)²+(y2-y1)²√(3-0)²+(5-0)²√9+25√34

Thus the equation of circle:

(x - 0)² + (y - 0)² = (√34)²(x - 0)² + (y - 0)² = 34x² + y² = 34

Answer:

H.  [tex]x^2+y^2=34[/tex]

Step-by-step explanation:

Equation of a circle (in standard form)

[tex](x-h)^2+(y-k)^2=r^2[/tex]

(where (h, k) is the center and r is the radius of the circle)

Given center = (0, 0):

[tex]\implies (x-0)^2+(y-0)^2=r^2[/tex]

[tex]\implies x^2+y^2=r^2[/tex]

As the circle passes through point (3, 5):

[tex]\implies 3^2+5^2=r^2[/tex]

[tex]\implies r^2=34[/tex]

Final equation

[tex]x^2+y^2=34[/tex]

A. (6, 4)
B. (8,3)
C. (3,8)
D. (4,2)

Answers

Step-by-step explanation:

The general form of the equation of a circle is

(x-a)^2 + (y-b)^2 = r^2   where the center is (a,b)

Plugging in the given values:-

(6 - a)^2 + (4-b)^2 = r^2    and

(6-a)^2 + (2-b)^2  = r^2

Subtracting:-

(4-b)^2 - (2 - b)^2  = 0

16 - 8b + b^ - (4 -4b + b^2) = 0

12 - 4b  = 0

-4b =  -12

b = 3

Similarly if we take the 2 points (6,2) and G(10,2)  and make two equations we can find the value of a

(6-a)^2 + (2-b)^2  = r^2

(10.a)^2 + (2-b)^2 = r^2    subtract::-

(6-a)^2 -(10-a(^2 = 0

this will give a = 8

so the center of the circle is  the poit (8,3)

What is the future value of the loan?

The future value of the loan is determined based on no subsidy and interest rate compounded for two years for the Junior Loan.

Junior loan Amount after two years = $4,539.76

Total of 120 Payments   $6,020.76

Total Interest   $1,481.00

Loan Amount = $5,295

Loan Term = 10 years

Interest Rate = 7.6%

Compound Monthly (APR)

Pay Back Every Month

Therefore, a Payment Every Month  of $63.13

Total of 120 Payments   $7,575.51

Total Interest  $2,280.51
