The equation is:
h ( t ) = - 16 t² + 60 t + 3
The toy rocket will reach the ground when: h ( t ) = 0
- 16 t² + 60 t + 3 = 0

t 1 = - 0.05
t 2 = 3.8

Answer:No, she does not have enough cups of sugar
Step-by-step explanation:
Sarah needs to make a cake and some cookies. The cake requires 3/4 cups of sugar. If she has 15/16 cups of sugar, then the number of cups of sugar that would be left after making the cake would be
15/16 - 3/4 = (15 - 12)/16 = 1/4
If the cookies require 3/5 cups of sugar, then the cups of sugar that she has won't be enough because
1/4 - 3/5 = (5 - 12)/5 = -7/5 cups
It means that she would need more cups of sugar.
