Answer:
Step-by-step explanation:
The given function are;
f(x) = x² - 3·x - 12, and g(x) = -x - 12
Therefore;
g(-8) = -(-8) - 12 = 8 - 12 = -4
∴ f(g(-8)) = f(-4) = (-4)² - 3×(-4) - 12 = 16
Therefore;
Answer:
x ≈ 66.73
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan27° = =
=
( multiply both sides by x )
x × tan27° = 34 ( divide both sides by tan27° )
x = ≈ 66.73 ( to 2 dec. places )
