Hey, I have this hw question that's really confusing me, any help would be appreciated. An object is fired upwards with an initial velocity of 112 feet per second. It's bright, in feet above the ground, as a function of time, in seconds since it was fired, is given by the equations h(t) = -16t^2 + 112t (A) At what height was the object fired. (B( Algebraically, find the time that the rocket reaches its greatest height and the maximum height (C) Algebraically, determine the time when the rocket reaches the ground Thanks a million!!

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

step-by-step explanation:

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
