Answer:

After making the subtract the answer is -13.

Step-by-step explanation:

In this case the question is a subtract, we just have to subtract both of the equations, this is:

$-8+b^{2} -(5+b^{2} )\\=-8+b^{2} -5-b^{2} \\=-13$

After making the subtract the answer is -13.

-8+b2-(5+b2). Since the - is outside the paranthesis the signs inside change: -8+b2-5-b2. -8-5=-3, b2-b2=0. Your answer: -3 :)

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

$64-19.19=44.81\ ft$

Find the slope of the line. pleaseee

Akimi4 [234]

Answer:

Step-by-step explanation:

The slope is the change in y divided by the corresponding change in x:

∆y/∆x = (54.99 -54.99)/(7 -6) = 0/1 = 0

The slope of the line is zero.

What is the distance between these points C(-4,1) and D(1,1)

Maslowich

Answer:

Step-by-step explanation:

Use the distance formula

d= $\sqrt{(1+4)^{2}+(1-1)^{2} }$

$d=\sqrt{5^{2}+0^{2} }$

$d=\sqrt{25+0} \\d=\sqrt{25} \\d=5$

Hope this helps!

Find the midpoint of the line segment with the given endpoints: (-1, -6) and (-6, 5).

Vikentia [17]

Answer:

Step-by-step explanation:

First, we will find the midpoint for the x - coordinate first.

Midpoint (x) = $\frac{-1+(-6)}{2} \\=\frac{-1-6}{2} \\=\frac{-7}{2} \\=-3.5$

Now we will find the midpoint for the y - coordinate.

Midpoint (y) = $\frac{-6+5}{2} \\=\frac{-1}{2} \\=-0.5$

Therefore from these 2 values we know that the midpoint of this 2 points is (-3.5,-0.5)
