Answer:

x = 7

3x + 11 = 32

8x + 2 = 58

Step-by-step explanation:

3x + 11 + 8x + 2 = 90

11x + 13 = 90

11x = 77

x = 7

3x + 11 = 3(7) + 11 = 32

8x + 2 = 8(7) + 2 = 58

For what value of x is the rational expression below undefined? x+8/x^2 -2x-24

Katena32 [7]

First step: Factor the expression.
(x + 8) / (x - 6)(x + 4)
Set each factor of the denominator equal to zero.
x - 6 = 0 x + 4 = 0
add 6 to both sides subtract 4 from both sides
x = 6 x = -4
The function would be undefined if x = 6 or x = -4

You are standing on a small fire tower 50 feet from a tree. You notice a squirrel in the tree. You measure the angle of depressi

irina [24]

Answer:

44.81 feet

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the right triangle ACD

Find the length side AC (height of the small fire tower)

$tan(52^o)=\frac{AC}{50}$ ---> by TOA (opposite side divided by the adjacent side)

Solve for AC

$AC=tan(52^o){50}$

$AC=64\ ft$

step 2

In the right triangle ABE

Find the length side AB

$tan(21^o)=\frac{AB}{50}$ ---> by TOA (opposite side divided by the adjacent side)

solve for AB

$AB=tan(21^o){50}$

$AB=19.19\ ft$

step 3

How many feet off the ground is the squirrel?

Subtract the length side segment AB from the length side segment AC

$64-19.19=44.81\ ft$
