You and some friends went to a haunted house on Halloween. The mummy scared one friend so much that she jumped into the air! The equation h = 4t (2) + 2t models her jump where h is her jumps height in feet t seconds after the mummy scares her. Where did she reach her maximum.

She reaches her maximum height after 0.25 seconds

Step-by-step explanation:

The question is not properly structured and the equation is also incorrect. Here is the correct question.

You and some friends went to a haunted house on Halloween. The mummy scared one friend so much that she jumped into the air! The equation h = - 4t² + 2t models her jump where h is her jumps height in feet t seconds after the mummy scares her. When did she reach her maximum.

Give the equation h = - 4t² + 2t that models my friend jump where h is her jumps height in feet t seconds, At maximum height, her velocity will be zero i. e

Vmax = 0m/s

Velocity is the rate of change in distance of a body i. e V = dh/dt

Given h = - 4t² + 2t

V = dh/dt = - 8t+2

Since v = 0m/s

0 = - 8t+2

-8t = - 2

t = - 2/-8

t = 0.25 secs

She reaches her maximum height after 0.25 seconds
