ASAP 25 POINTS WILL MARK BRAINLIEST MULTIPLE CHOICE Determine whether the sequence of mapping rules will lead to the image being congruent to the pre-image (x, y)→(−x, .5y)
Question 2 options:

Yes, this is a reflection which doesn't change the pre-image size

Yes, this is a translation which doesn't change the pre-image size

No, the image will be bigger than the pre-image

No, the image will not be same size as the pre-image

No, the image will not be same size as the pre-image

Step-by-step explanation:

0.5y means it's getting shrunk in the y-axis so it is no longer congruent. D is the correct answer because it is no longer the same size as the pre-image.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
