in the blanks below. Find the slope of the line passing through the points (-9, 2) and (9,2). slope:

user100 [1]

I will assume that we are trying to find the slope between (-9,2) and (9, 2)

The slope's equation ⇒ $\frac{y2-y1}{x2-x1}$

Let's set the variables:

(x1, y1) --> (-9, 2)

(x2, y2) --> (9, 2)

Now let's plug them in:

$Slope = \frac{2-2}{9--9} =\frac{0}{18} =0$

Thus the slope of the line is 0.

Hope that helps!

Suppose you drop a ball from 120 feet. The ball will bounce to 25 of its previous height. What is the total distance the ball tr

tamaranim1 [39]

Answer:

277.1 feets

Step-by-step explanation:

Drop height = 120 feets

Ball bounces 2/5 of previous height

Height after 1st bounce :

120 * 2/5 = 48 feets

Return distance = 48 feets

Height after second bounce :

48 * (2/5) = 19.2 feets

Return distance = 19.2 feets

Height after 3rd bounce :

19.2 * (2/5) = 7.68 feets

Return distance = 7.68 feets

Height after 4th bounce :

7.68 * (2/5) = 3.072 feets

Return distance = 3.072 feets

Height after 5th bounce :

3.072 * (2/5) = 1.2288 feets

(120 + (2*48) + (2*19.2) + (2*7.68) + (2*3.072) + 1.2288) = 277.1328

= 277.1 feets

Solve : t+2t squared

zloy xaker [14]

Answer:

t=0 or t=-1/2

Step-by-step explanation:

Solve for t over the real numbers:

t (2 t + 1) = 0

Split into two equations:

t = 0 or 2 t + 1 = 0

Subtract 1 from both sides:

t = 0 or 2 t = -1

Divide both sides by 2:

Answer: |

| t = 0 or t = -1/2

Guys we have a big test tomorrow, and it is about angles and fractions and I just need someone to refresh my brain. Just answer

pishuonlain [190]

A right angle measures an angle exactly 90 degrees, obtuse= more than 90, acute less than 90 degrees. Triangle angles add up to 180 degrees quadrilaterals measure up to 360 degrees. A fraction can be written as a decimal or percent answer. A fraction is not a whole number. The reciprocal is the opposite of that number/ fraction. Pls give brainliest.
