Answer:
The period when its more than halfway
= 2 < t ≤ 2.83 seconds ( to nearest hundredth).
Step-by-step explanation:
When is is halfway down the ramp d = 3920/2 = 1960 cm, so:
1960 = 490 t^2
t^2 = 1960/490 = 4
t = 2 seconds.
When it reaches the bottom d = 3920 :
t^2 = 3920/490 = 8
t = 2.83 seconds.
In this equation the 9.1 would represent the amount the tip would have been before the adjustment is made (1.4d) for the dessert.
The number would be 21 because if you add 5+37 then divide by 2.Younwill get the answer
