A football is kicked into the air with an initial upward velocity of 82 feet per second. It's height, h (in feet), is recorded at various seconds, t, in the table below. (look at picture)

1. write the equation for the curve best fit?
2. estimate the height of the football after 5 seconds.
3. estimate when will the football hit the ground.

answer choices:
h= -16t^2-82t
h=16t^2+82t
h= -16t^2+82t
h=16t^2-82t
5 feet
5 seconds
10 seconds
10 feet
810 feet
810 seconds ​

Jessica and martha each have a bag of cookies with unequal quantities. they have 30 cookies total between the two of them. each of them ate 6 cookies from their bag. the product of the number of cookies left in each bag is not more than 80. how many more cookies will jessica have martha? if x represents the number of cookies jessica started with, complete the statements below.the inequality that describes the relationship between the number of cookies each one of them has is x^2 - x +224 > = 0.jessica has at least cookies more than martha.
