The formula h=-16t^2+vt+c describes the height of an object thrown into the air, where h is the height, t is the time in seconds, v is the initial velocity, and c is the initial height. Use the formula to answer the question. A football is thrown with an upward velocity of 80ft/s from an initial height of 6 feet. How long will it take for the football to reach its maximum height? How far above the ground will it be?

step-by-step explanation:

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
