What is being asked here? Are they asking for the passing grade or the total with all the other 90 points added? I think it is A, 90%
4^4 is simply 4x4x4x4 and 4^7 is 4x4x4x4x4x4x4
Answer:

Step-by-step explanation:
Angle EFB = 180 - 147 = 33 (Angles on a straight line add up to 180 degrees)
Angle FEB = 180 - 4x (Angles on a straight line add up to 180 degrees)
Since the angles in a triangle add up to 180 degrees ,

Remove brackets:

Add/Subtract:

Subtract 213 from both sides:


Divide both sides by -3:


You are given h(t) = 64–16t^2.
You need to find h(1.25).
Set up:
h(1.25) = 64 - 16(1.25)^2
Take it from here.
