A ball is thrown from a height of 255 feet with an initial downward velocity of 21/fts. The ball's height h (in feet) after t seconds is given by the following. =h−255−21t16t2
How long after the ball is thrown does it hit the ground?
Round your answer(s) to the nearest hundredth.

1 is c

2 is a

3 is a

step-by-step explanation:

i will pick c put check it over to be sure

step-by-step explanation:

step-by-step explanation:

this is not a question

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
