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.
There is no table!!!! Please put a table the next time!!!!
Answer:
First question --> C) 8.5h
Second question --> D) 2
Step-by-step explanation:
First question
Terry earns $10 per hour
Jill earns 20% less which is $2 less
Jill earns $8 per hour
Jerry earns $0.50 more per hour than Jill
Jerry earns $8.50 per hour
Second question
x = 2
y = 4
(2x + 3y) / 4 - 2 = ?
Use PEMDAS
so Parentheses first, then divide, then subtract
So.... (2x + 3y) = (2*2 + 3*4) = (4 + 12) = 16
Then divide
16/4 = 4
Then subtract
4 - 2 = 2
