The height of a rocket launched upward from a 160 foot cliff is modeled by h = -16t^2+48t+160, where h is the height in feet and t is the seconds. feet and t is the time in seconds. How many seconds was the rocket in the air?
the rocket was in the air for seconds.

step-by-step explanation:

where is the questions

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
