Question

Task 3:

You and some friends went to a haunted house on
Halloween. The mummy scared one friend so much that she
umped into the air! The equation h = -4T^2+ 2t models her
ump where h is her jump's height in feet t seconds after the
mummy scares her.
A: How long was your friend in the air?
B:How high did your friend jump?
C:When did she reach her maximum height?

Answer 1

Answer: A: To find how long your friend was in the air, we need to determine when the height, h, reaches zero. We can set the equation -4T^2 + 2t = 0 and solve for T.

B: To find how high your friend jumped, we can substitute the time she was in the air, which we calculated in part A, into the equation h = -4T^2 + 2t.

C: To find when she reached her maximum height, we need to determine the time at which the equation h = -4T^2 + 2t reaches its maximum value. We can use the vertex formula for a quadratic function to find this time.
