Can someone help me? And no, I don’t just want the answer. I literally need to know how to do it pls
elena-s [515]

Answer:

36

Step-by-step explanation:

The angle b is a right angle which is divided into 2. So, each angle would measure 45 degree. (90 / 2 = 45)

tan 45 = 1

\AD\ = 100 - 64 = 36

to find x , remember SOCAHTOA

tan would be used because we have the vale of the opposite angle and we want to find the value of the adjacent angle

Tan 45 = opposite / adjacent

1 = 36/x

x = 36

F(x) = x^2, g(x) = 2/3 x^2 comparison
daser333 [38]

Answer:

g(x) is a vertical compression of f(x)

Step-by-step explanation:

Equation of graph 1 :f(x)=x^2

Equation of graph 2 :g(x)=\frac{2}{3}x^2

f(x)→a f(x)

Its is case of vertical stretch or compression

Vertical stretch if |a|>1

Vertical compression if 0<|a|<1

f(x)→a f(x)

So, x^2 →\frac{2}{3}x^2

So, a= \frac{2}{3}=0.67

So,0<|a|<1

So,It is a case of vertical compression

So, g(x) is a vertical compression of f(x)
