The graph of g is a vertical shrink by a factor of 13and a reflection in the y-axis, followed by a translation 3 units right of the graph of f(x)=x2. Write a rule for g. Then identify the vertex.

answer is  

a.

p = 78

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
