A projectile is fired from ground level such that its height, h, as a function of time, t, is given by h = "-16t^2" + 80t. Written in factored form this equation is equivalent to(1) h = -16t(t+4)(2)h = -8t(2t-7)(3)h = -16t(t-5)(4)h = -8t(t-5)

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the answer is c)8

step-by-step explanaction:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
