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) = -16 + 72t + 5
2. <u>What is the maximum height of the t-shirt?</u>
<u />
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 ]

Step-by-step explanation:
The z-score measures how many standard deviations a score X is above or below the mean.
It is given by the following formula:
In which is the mean and
is the standard deviaition.
In all three cases, we have to find X
a. Final exam scores: Allison’s z-score = 2.30, μ = 74, σ = 7.
b. Weekly grocery bill: James’ z-score = –1.45, μ = $53, σ = $12.
Mean and standard deviation in dollars, so the answer also in dollars.
c. Daily video game play time: Eric’s z-score = –0.79, μ = 4.00 hours, σ = 1.15 hours.
Mean and standard deviation in hours, answer in hours.
