Performance is your grades, and home study can be reading, so the score is positive in the second half, too.
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
Answer:
-18a^8
Step-by-step explanation:
= 3m-10m - 20 + 1/5
= -7m - 19 4/5
