<em>Part A</em>
1) x intercept represents when the ball is on the ground.

2) Max value represents the highest height that the ball can reach, which is 15 feet.

3) Interval that is increasing : when the distance goes from 0 feet to 10 feet. (The ball is going up)

4) Interval that is decreasing : when the distance goes from 10 feet to 20 feet. (The ball is coming down)

<em>Part B</em>
At distance = 12, height = 14
At distance = 15, height = 11
Change in distance = 15 - 12 = 3 feet
Change in height = 14 - 11 = 3 feet
Average change = 1 feet height per 1 feet distance
This represents the rate of deceleration.

12 one half times one nine

pshichka [43]

Answer:

$1\frac{7}{18}$ or one seven eighteenths

Step-by-step explanation:

we know that

12 one half times one nine is the same that multiply 12 one half by one nine

$(12\frac{1}{2})(\frac{1}{9})$

Convert mixed number to an improper fraction

$12\frac{1}{2}=12+\frac{1}{2}=\frac{12*2+1}{2}=\frac{25}{2}$

substitute

$(\frac{25}{2})(\frac{1}{9})=\frac{25}{18}$

Convert to mixed number

$\frac{25}{18}=\frac{18}{18}+\frac{7}{18}=1\frac{7}{18}$

therefore

12 one half times one nine is one seven eighteenths

(See the imagine for reference)
Let’s solve where they have a triangle, so the height is 9 cm, the base is 3 cm:

1/2 • 9 • 3 = 13.5

Since there’s 2 triangles we do:

13.5(2) = 27

Now the rectangle in the middle, where the height is 9cm and the base is 12cm:

12 • 9 = 108

Add up the areas:

108 + 27 = 135
