The height (in feet) of punted football is a function of the time the ball is in the air. The function is defined by h(t) = - 7t
Kamila [148]

Answer:

The height of the football after 4 seconds is 80 feet.

Step-by-step explanation:

You know that the height (in feet) of punted football is a function of the time the ball is in the air and it is defined by:

h(t) = -7*t²+48*t

To calculate the height of the ball after 4 seconds, you must replace the time t by the time of 4 seconds:

h(4) = -7*4²+48*4

Solving, you get:

h(4) = -7*16+48*4

h(4) = -112+192

h(4)= 80

<u><em>The height of the football after 4 seconds is 80 feet.</em></u>

Area of the trapezoid:
\frac{12.8 + 4.2}{2} (4.9) = 41.65 cm^2

Area of the rectangle:
4.2 x 3.1 = 13.02 cm^2

Area of each quarter circle:
\frac{ \pi  (3.1)^{2} }{4} = 7.54 cm^2

We have two quarter circles:
7.54 + 7.54 = 15.08

41.65 + 13.02 + 15.08 = 69.75 cm^2

The cost of a car rental is ​$35 per day plus 21 cents per mile. You are on a daily budget of ​$98. Write and solve an inequalit
erma4kov [3.2K]
Let x = mileage
98 >= 35 + .21x
Solving for x:
98 >= 35 + .21x
63 >= .21x
300 >= x
.
This says that if the total mileage is 300 miles or less he will be within his budget.
