An object is launched vertically in the air at 46.55 meters per second from a 6-meter-tall platform. Using the projectile motion model h left parenthesis t right parenthesis equals negative 4.9 t squared plus v 0 t plus h 0 comma where h(t) is the height of the projectile t seconds after its departure, v 0 is the initial velocity in meters per second, and h 0 is the initial height in meters, determine how long it will take for the object to reach its maximum height. What is the maximum height?

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

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.
