Question

An object is fired upward from the top of a 200 ft. tower at a velocity of 80 ft/sec. The height of the object, h(t), is modeled by the function h(t) = -16t2 + 80t + 200, where t represent the time in seconds.

Answer 1

Howdy my friend

Answer 5

Right. But there would be more questions concerning that question you just typed.

Answer 6

You know the equation and everything that's great

Answer 7

Which time is specified? I bet you are left to use the formula to calculate the height of the object at certain time following the launch

Answer 8

I have to find the Maximum

Answer 9

Let's graph.

Answer 10

ok

Answer 11

Find the vertex.

Answer 12

That is the point at which the parabola reflects.

Answer 13

Do you have an access to online calculator or would you like me to do it?

Answer 14

I would like you to show me

Answer 15

I am on it just a sec

Answer 16

ok

Answer 17

y=-16t ^ 21+80t+200

Answer 18

Type that into desmos calculator. You should get a vertex of (2.5,300)

Answer 19

It's saying that after 2.5 seconds from the launch the height of the object reaches 300m

Answer 20

Did you get it or not?

Answer 21

yes

Answer 22

so is 300m
