Answer:

g(-2)=-7

Step-by-step explanation:

start by replacing x with -2

g(-2)=5-3(-2)^2

nasty-shy [4]

Answer:

$81.2\:\mathrm{ft}$

Step-by-step explanation:

We can form a right triangle and use basic trig for a right triangle to solve this problem:

$\tan33^{\circ}=\frac{h}{125}$ , where $h$ is the height of the tree.

Solving, we get:

$h=125\cdot \tan 33^{\circ},\\h\approx \fbox{$81.2\:\mathrm{ft}$}$ .
