It is 5 since u need to jump 5 times 4,8,12,16,20=5 times 4
-16t^2+400=0
16t^2=400
take square root on both sides.

4t=20
t=20/4
t=5
Answer:
14, 16, 18
Step-by-step explanation:
x + (x+2) + (x+4)= 48
3x + 6 = 48
3x = 42
x = 14
x+2 = 16
x+4 = 18
Check the picture below.
with negative angles, we go "clockwise", the same direction a clock hands move.
so -360-360-125 = -845.
so as you see in the picture, you go around twice, and then a little bit more, an extra 125°, landing you at -125°, or its positive counterpart, 235°.
