Answer:
sure if im able, with what?
Step-by-step explanation:
Answer: t = 6 s
Step-by-step explanation:
When Rose hit the water, the height of the jump is 0, so: h(t) = 0.
Resolving it, we have:
-16t² + 16t + 480 = 0
To simplify the second degree equation, divided it by 16:
-t² + t + 30 = 0
Now, solve the equation using Bhaskara:
Δ = 1² - 4. (-1) . 30
Δ = 1 + 120
Δ = 121
t = 
t₁ =
= - 5
t₂ =
= 6
Since time can be negative, it took t = 6s for Rose to hit the water.
There are three terms in alg exp
9^3= 729, 729 x 4=2916, 2916/3=972, 972 x 3.14 =3052.08
Assuming the missing parenthesis is at the end the simplified answer should be k-8
