Question

Use the graph to estimate the height of a jugglers ball that has been in the air for 1.5 seconds

Answer 1

The height of a jugglers ball that has been in the air for 1.5 seconds is 6.5 feet

Explanation:

we are given height equation as

`h=-16t^2+25t+5`

where

h is the height in feet of a Juggler's ball after t seconds

now, we can plug t=1.5

`h=-16(1.5)^2+25(1.5)+5`

we can solve for h

`h=42.5-16\cdot \:1.5^2`

`h=42.5-36`

`h=6.5`

So,

The height of a jugglers ball that has been in the air for 1.5 seconds is 6.5 feet
