Answer:
3a.=20ft 3b.=1 second 3c.=3.25seconds
Step-by-step explanation:
Hello, Courtney!
h(t)=-5t^2+10t+20
20 would be the height so 3.a would be 20ft
3b. 25=-5t^2+10t+20
-5t^2+10t-5 then divide by greatest factor the answer would 1 second
3c. 0=-5t^2+10t+20 divide by greatest factor and would get 3.25 and -1.25 but can't have negative so the answer is 3.25.
I hope this helps
best you know who!

Answer:
A) 18%
Step-by-step explanation:
Find percent change by subtracting to find the change, then put that over the original amount and times by 100.

0.177×100 is 17.7%
which rounds to 18%.
