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:
C ) 3.80 s
Answer:
Plug in the values for x
Step-by-step explanation:
plug in x values into the equation
for example, plug -2 into the equation. y= -2(-2). y=4
So on and so forth
Answer:
You need to put the answer choices so we can answer the question for you
Step-by-step explanation:
2x-y=60/100* 5y
2x-y= 6*5y/10
2x-y=3y
2x=3y+y
2x=4y | :2
x=2y | :x
1=2y/x :2
⇒ y/x= 1/2
