Step-by-step explanation:
To find the length of I’F’
We perform the dilation on IF using the given dilation factor
All we have to do here is to multiply the length of IF by the dilation factor
We have this as ;

You are building a doghouse for Fido, your loyal poodle. The blueprint of the doghouse uses a scale of 1 : 14. The floor of the doghouse measures 2" x 2.5" on the blueprint.
Answers
Answer:
28" x 35"
Step-by-step explanation:
Based on the ratio we see that for every 1 inch in the blueprint there are a total of 14 inches in the real-life model of the doghouse. Therefore, in order to find the actual dimensions of the real-life doghouse we simply need to multiply the individual length and width dimensions of the blueprint by 14. Since the real-life model is 14 times bigger according to the ratio.
2 * 14 = 28
2.5 * 14 = 35
Finally, we can see that the real-life doghouse has a the following dimensions 28" x 35"
Two possible plans for a new bathroom are shown. Is there a value of x for which the perimeters are equal? Show your work. Explain the reasoning.
Answers
Answer:
There is no value of x to fit this requirement.
Step-by-step explanation:
The 2 perimeters in terms of x are:
4(x + 3) for the square and
2(x+1) + 2(x +4) for the rectangle
and these need to be equal so
we equate these 2 and solve for x:
4(x + 3) = 2(x+1) + 2(x +4)
4x + 12 = 2x + 2 + 2x + 8
4x + 12 = 4x + 10
4x - 4x = 10 - 12
0 = -2 which is of course absurd so there is no solution to this equation.
Answer:
(x+3)•4=(x+4)•2+(x+1)•2
Step-by-step explanation:
4x+12=2x+8+2x+2
4x-2x-2x=-12+8+2
0=-2
this expression is indeterminate.

What is the average rate of change over the interval 1≤x≤3
Answers
9514 1404 393
Answer:
3
Step-by-step explanation:
The average rate of change is the slope of the line between the points at the ends of the interval: (1, -2) and (3, 4). That is given by the slope formula ...
m = (y2 -y1)/(x2 -x1)
m = (4 -(-2))/(3 -1) = 6/2
m = 3
The average rate of change on the interval is 3.

Answers
Complete Question
The mean height of a basketball team is 6 feet with the standard deviation of 0.2 feet. The team center is 6.9 feet tall. Find the center Z score. Is the score unusual?
Answer:
Center Z score = 4.5
The score is unusual
Step-by-step explanation:
The mean height of a basketball team is 6 feet with the standard deviation of 0.2 feet. The team center is 6.9 feet tall. Find the center Z score. Is the score unusual?
The formula for z score is:
z = (x-μ)/σ, where
x is the raw score = 6.9feet
μ is the population mean = 6feet
σ is the population standard deviation = 0.2 feet
Hence:
Z = 6.9 - 6/0.2
Z = 0.9/0.2
Z = 4.5
Yes this score is unusual

What is dilation?Dilation is a type of transformation in geometry, in which the original figure changes its scales, either reduce or enlarge.
Given are scale factors,
Scale factor symbolized by k,
We know that, when k > 1, the figure expands or enlarge.
When k < 1, the figure reduces or contract.
And when k = 1, the figure is congruent to the dilation.
1) -5 = (contraction)
1 > -5, therefore, figure is contraction.
2) -1/4 = (contraction)
1 > -1/4, therefore, figure is contraction.
3) 3.5 = (expanding)
1 < 3.5, therefore, figure is expanding.
4) 6/7 = (contraction)
6/7 = 0.8571 < 1, therefore, figure is (contraction)
Hence, -5 = (contraction), -1/4 = (contraction), 3.5 = (expanding) and 6/7 = (contraction)

The measure of ∠A is 12° greater than the measure of ∠B. The two angles are complementary. Find the measure of each angle.
The m∠A is __° and m∠B is __°.
Answers
Answer:
39° = m∠A
51° = m∠B
Step-by-step explanation:
Complementary angles have a sum of their measures = 90
Let x = m∠B
then x + 12 = ∠A
m∠A + m∠B = 90
x + 12 + x = 90
2x + 12 = 90
2x = 78
x = 39° = m∠A
x + 12 = 39 + 12 = 51° = m∠B
The measure of ∠A is 39°.
The measure of ∠B is 51°.
Here,
The measure of ∠A is 12° greater than the measure of ∠B.
The two angles are complementary.
We have to find the measure of each angle.
What is Complementary angle?
Complementary angles have a sum of their measures is 90°.
Now,
The measure of ∠A is 12° greater than the measure of ∠B.
Let m∠B = x
Then, ∠A = x + 12
The two angles are complementary.
Hence,
m∠A + m∠B = 90
x + 12 + x = 90
2x + 12 = 90
2x = 78
x = 39°
And, x + 12 = 39 + 12 = 51°
Hence, The m∠A is 39° and m∠B is 51°.
