In the given figure, PT is a tangent to the circle and PA = 3 x PT. (diagram is not to scale)

What is the length of AB in terms of b?

b. astronomers

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

it would open into a square depending on the type of envelope i’m not sure about the second part
