Answer: let me check
Step-by-step explanation:
Greetings!
"<span>Paula is now four times the age of Lynn. Lynn will be 16 in 10 years. How old was Paula four years ago?"
If Lynn will turn sixteen in ten years, she must be 6 at the current moment:
16-10=6
Since Paula is 4 times the age of Lynn, Paula must be:
6(4)
=24
24-4
=20
Paula was 20 years old, 4 years ago.
Hope this helps.

Answer: From what you wrote the I think the ball is drop
At time 0 you are 7 meters above ground
You basically just need to solve for
1.5 =7t-4.9t^2
by rearrange the equation you get
4.9t^2-7t+1.5=0
by using Quadratic Formula
t=1.166s
(10x)^ (-3)
= 1/ [(10x)^3]
= 1/ [10^3* x^3]
= 1/ (1000x^3)
The final answer is 1/ (1000x^3), and I don't think there is a correct option to choose from. ( option c would be correct if it were written with round brackets)
Hope this helps~
