A smart-phone is thrown upwards from the top of a 672-foot building with an initial velocity of 16 feet per second. The height h of the smart-phone after t seconds is given by the quadratic equation

h=−16t^2+16t+672

. When will the smart-phone hit the ground?

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

add a pic of the graph, then ill edit this "answer" and solve it for you : 3

step-by-step explanation:

i think the answer is b x = 1, y = 35/2
