The dilation of the circle with a scale factor 1/r and center at (a,b) will transform the circle into a point at (a,b).

A dilation is a transformation that results in an image with the same shape as the original but a different size. • An enlargement is a dilation that produces a larger image. • A reduction is a dilation that produces a smaller image.

To solve this we will use the transformation formula for a dilation with center (a,b) and scale factor

k, (x,y) --> (a + k(x-a), b + k(y-b)).

Substituting in our values, we get

(x,y) --> (a + (1/r)(x-a), b + (1/r)(y-b)).

Setting this equal to (a,b), we get

(a + (1/r)(x-a) = a, b + (1/r)(y-b) = b).

Solving for x and y gives x = a and y = b. Therefore, the dilation of the circle with a scale factor of 1/r and center at (a,b) will transform the circle into a point at (a,b).

Answer:

16.8 inches

Step-by-step explanation:

Perimeter =2(length+width) so 2·(5.6+2.8)≈16.8

Answer and Step-by-step explanation:

First, write down what we know.

Length of Rectangle = [tex]5\frac{3}{5}[/tex]

Width = [tex]\frac{Length}{2}[/tex]

2 ways to solve this:

1st way:

If we convert the fraction into a decimal, then we can easily find the width.

[tex]5\frac{3}{5}[/tex] can be solved by making the mixed number into a improper fraction.

Multiply the denominator (5) by the whole number (5), then add the numerator (3). This number is 28. Replace the 3 with the 28, and now we have [tex]\frac{28}{5}[/tex]. This number is equal to 5.6.

Now, we have to divide this number.

5.6 divided by 2 is equal to 2.8.

So, the width is equal to 2.8.

Now, we add the width and length together twice to get the perimeter of the rectangle.

2.8 + 2.8 + 5.6 + 5.6 = 16.8

So, the answer is A. 16.8 inches.

2nd way:

Since we know that the width is half of the length, we can just add the length by itself 3 times, since two of the widths combined will equal the length.

5.6 + 5.6 + 5.6 = 16.8

So, the answer is A. 16.8 inches.

Answer:

a.  The total cost of fixing the drain is $198

b. The plumber spend 13 hours fixing the drain

Step-by-step explanation:

We know the equation is

C=25h+73

C = the total cost

h = the number of hours

Let's solve question a by putting 5 in for h

C=25(5)+73

C = 125 + 73

C = $198

So, the total cost of fixing the drain is $198

Let's solve question b by butting 398 in for c

398=25h+73

325 = 25h

h = 13 hours

So, the plumber spend 13 hours fixing the drain

Answer:

120

Step-by-step explanation:

So there are two ways of doing this.

The easiest, we know that the biggest of 30, 60 and 90 degrees is 90.

We know that a right angle is 90 degrees.

The 1 angle is clearly bigger than 90 degrees.

So it must be 120.

The actual way of solving:

The mini trinalge that has the 90 degree angle in it is a 30, 60, 90 trinalge.

We know that the 3 is the 30 degree angle on the trinalge.

We know that the angle on the opposite side of the dotted line must be 30 as well.

Since thats 30, the opposite side of the dotted part of thr traingle must be 30 as well.

This means that the other two angles are 60 which you subtract from 180

This leaves 120

So 120 degree angle is the answer

The degree of a polynomial is the highest power of each variable in the equation. In the polynomial 7x2y3z4, the highest power of each variable is 2 for x, 3 for y, and 4 for z. Therefore, the degree of this polynomial is 8.

1. Identify the highest power of each variable.

For 7x2y3z4, the highest power of each variable is 2 for x, 3 for y, and 4 for z.

2. Add the highest powers of each variable.

2 + 3 + 4 = 9

3. Subtract 1 from the sum.

9 - 1 = 8

4. The degree of the polynomial is the result of the subtraction.

Therefore, the degree of the polynomial 7x2y3z4 is 8.

The degree of a polynomial is the highest power of each variable in the equation. To calculate the degree of a polynomial, you must identify the highest power of each variable and add them together. Then, subtract 1 from the sum to get the degree of the polynomial. For example, in the polynomial 7x2y3z4, the highest power of each variable is 2 for x, 3 for y, and 4 for z. Adding these powers together gives us 9. Subtracting 1 from this sum gives us 8, which is the degree of the polynomial. Therefore, the degree of the polynomial 7x2y3z4 is 8.

To find:

The fraction form of the Sharla's batting average.

Solution:

It is given that Sharla's batting average is 0.583. So, it can be written as:

[tex]0.583=0.583\times \dfrac{1000}{1000}[/tex]

[tex]0.583=\dfrac{583}{1000}[/tex]

This fraction can not be simplified further because there is no common factor of 583 and 1000.

Therefore, the fraction form of the Sharla's batting average is [tex]\dfrac{583}{1000}[/tex].

We can tell if a number is rational or irrational by Venn Diagram

Both irrational and rational numbers are exact, yet they have different properties. Any number that can be expressed as P/Q, where P and Q are both integers and Q is more than zero, is considered to be reasonable. Simple fractions, however, cannot be used to express an irrational number. An illustration of a rational number is 2⅔ 3, while an irrational number is √2.

All integers, fractions, and repeating decimals are included in the concept of a rational number. We may represent every rational number as p/q, where p and q are integer numbers.

                 [3.65,3.74]

Step-by-step explanation:

The number after rounding off is obtained as:

                         3.7

We know that any of the number below on rounding off the number to the first decimal place will result in 3.7:

  3.65     3.66    3.67    3.68    3.69    3.70    3.71   3.72    3.73    3.74

( Because if we have to round off a number present in decimals to n place then if  there is a  number greater than or equal to 5 at n+1 place then it will result to the one higher digit  at nth place on rounding off and won't change the digit if it less than 5 )

        Hence, the error interval is:

            [3.65,3.74]

Step-by-step explanation:

it means that the graph of the function above y=x must be the mirrored image of the graph under y=x.

it means that the function applied to itself gives x.

f(f(x)) = x

e.g.

f(x) = 5 - x

f(f(x)) = 5 - (5 - x) = 5 - 5 + x = x

so, this f(x) is its own inverse.

Answer:

Cot(theta) = - 0.75 or -3/4

Step-by-step explanation:

The hypotenuse is 5

The y value is 4

We need to find the corresponding x value.

x^2 + y^2 = z^2

X = ?

y = 4

z = 5

x^2 + 4^2 = 5^2

x^2 + 16 = 25

x^2 = 9

Now in this case, you are in quadrant 2, so the x value is - 3

sqrt(x^2) = sqrt(9)

x = - 3

The cot value is the adjacent (x value) / the opposite ( y ) value

Cot(theta) = -3/4

cot(theta) = -0.75

Answer:

cotθ = -3/4

Step-by-step explanation:

Given:

sinθ = 4/5

θ is in Quadrant II, so cosθ < 0

Recall:

cotθ = cosθ/sinθ

cos²θ + sin²θ = 1

Determine cosθ:

cosθ = -√(1-sin²θ) = -√(1-(4/5)²) = -√(1-16/25) = -√(9/25) = -3/5

Determine cotθ:

cotθ = cosθ/sinθ = (-3/5)/(4/5) = (-3/5)(5/4) = -15/20 = -3/4

The length of y using sine rule is 6664.2 inches

The sine rule states that if a, b and c are the lengths of the sides of a triangle, and A, B and C are the angles in the triangle; with A opposite a, etc., then a/sinA=b/sinB=c/sinC.

in this case w/sinW = y/sinY

Y = 180-(55+42)

Y = 180-(97)

Y = 83°

Therefore 470/sin55 = y/sin83

470× sin83 = y sin55

= 466.50 = 0.707y

divide both sides by 0.707

y = 466.50/0.707

y = 6664.2 inches

therefore the length of y is 6664.2 inches

The spring constant is 30 N/m and the stretch when the 420 N force is applied is 14 cm.

The force needed or applied to compress or extend a spring on any attached object is known as the spring force.

A spring exerts an equal and opposite force on an object when the object exerts a force on it. It always takes action to get mass back to where it should be for equilibrium. 

Given that when 180 N force is applied the spring stretched by 6 cm. The spring stretch when the 420 N force is applied is calculated as,

First, calculate the spring constant,

F = kx

180 = k x 6

k = 30 N / m
