Answer:

Step-by-step explanation:

SV = RV

2x+2 = 10

x = 4

r² = RV² + VZ² = 10²+7.5² = 156.25

UZ = √[r²- (QR/2)²] = √[156.25 - 10²] = √56.25 = 7.5

If f(x) = -x^2 – 1, and<br> g(x) = x + 5, then<br> g(f (x)) = [? ]x^2+[ ]x + [ ]
inna [77]

Answer:

g(f(x)) = - x² + 4

Step-by-step explanation:

To evaluate g(f(x)), substitute x = f(x) into g(x), that is

g(f(x))

= g(- x² - 1)

= - x² - 1 + 5

= - x² + 4
