4vir4ik [10]

Hi,

During halftime of a soccer game, a slingshot launches T-shirts at the crowd. A T-shirt is launched from a height of 5 feet with an initial upward velocity of 72 ft. Per second. The T-shirt is caught 34 feet above the field. How long will it take the T-shirt to reach its maximum height? What is the maximum height? What is the range of the function that models the height of the T-shirt over time.

<u>Write the general equation that represents height of the t-shirt as a function of time. </u>

f(t) = -16t^{2} + 72t + 5

2. <u>What is the maximum height of the t-shirt?</u>

<u />t = \frac{-72}{2(-16)} = 2,25                         f(2,25) = -16(2,25)^{2} + 72(2,25) + 5

                                                                = 86 feet

1. <u>How long will it take the t-shirt to reach its maximum height?</u>

2,25 secondes

3. <u>The range describes which values of the graph? What would the range of this graph be? (Write in inequality and interval notation).</u>

height (y)

5 ≤ y ≤ 86        [ 5,86 ]

22)<br> Find x and y in each figure.
Maurinko [17]

Answer:

x= 10, y= 15

Step-by-step explanation:

because alternate interior angles are congruent

8x -10 = 7x

8x -7x = 10

x = 10

because straighht line form 180°

6y+20 +7x = 180

6y +20 +70 = 180

6y = 180 -90

y=90/6 = 30/2 = 15
