First we take the equation g(x) and plug it into x for f(x)
Step 1: F(g(x)) = (√(x) - 2)^2 + <span>3
</span>Step 2: F(g(x)) = x - 4<span>√(x) + 4 + 3
Step 3: F(g(x)) = x - 4</span><span>√(x) + 7</span>

Substitute g(x) for the x in f(x)

f(x)=x^2+3 \\  \\ g(x) \sqrt{x-2} \\  \\ f(g(x))=( \sqrt{x-2})^2+3 \\  \\ f(g(x))=x-2+3 \\  \\ f(g(x))=x+1

Answer:

9) QR = 4.0

10) AC = 4.1

Step-by-step explanation:

Tan = Opps. / Adj.

9)

Tan(60) = 7 / QR

QR = 7 / Tan(60)

QR = 7 / 1.732

QR = 4.0415

QR = 4.0

10)

Tan (27) = AC / 8

AC = Tan(27) * 8

AC = 0.5095 * 8

AC = 4.076

AC = 4.1
