I don't know what is between f(x) and g(x), so (for now) there are two posible answers:

1. $f(x)g(x) = f(x)\cdot g(x)$ - function multiplication:

$f(x)g(x)=(2x-3)\cdot(3x+8)=2x\cdot3x+2x\cdot8-3\cdot3x-3\cdot8=\\\\=6x^2+16x-9x-24=\boxed{6x^2+7x-24}$

2. $f(x)g(x)=f(x)\circ g(x)$ - function composition:

$f(x)g(x) = f(x)\circ g(x) = f\big(g(x)\big)=2(3x+8)-3=2\cdot3x+2\cdot8-3=\\\\=6x+16-3=\boxed{6x+13}$

Answer:

A. About 4,900 ft

Step-by-step explanation:

We want h such that ...

5 = 10·ln(h) -80

8.5 = ln(h) . . . . . . . add 80, divide by 10

e^8.5 = h ≈ 4914.8 . . . . take the antilog

h ≈ 4900 . . . . feet
