Question

Help

Answer 1

first plug the initial velocity and height into the equation, then find the axis of symmetry using x = -b/(2a)

Answer 2

so -16+110

Answer 3

so the equation becomes -16t^2 + 110t + 2

Answer 4

+2

Answer 5

a = -16
b = 110

find -b / (2a)

Answer 6

-110 / (2*-16)

Answer 7

good now simplify that (you can leave it as a fraction)

Answer 8

-110/-32

Answer 9

good, and that ends up being 55/16

now let t = (55/16) and find the height

Answer 10

(you can just use a calculator for this)

Answer 11

so it would be -16(55/16)^2 + 110(55/16) + 2

Answer 12

yup

Answer 13

191.1

Answer 14

i end up getting 3057/16 which rounds to 191.06 = your ans

Answer 15

(they want it to the nearest hundredth so it rounds to .06)

Answer 16

i round to the hundredth

Answer 17

righ tthanks =)
