For this case we have the following equation:
H (t) = - 16t ^ 2 + 28t
When the dolphin finishes a jump, then the height is equal to zero.
We have then:
-16t ^ 2 + 28t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 1.75 s
Therefore, the dolphin takes 1.75 seconds to make a jump.
Answer:
it will take for the dolphin to make one jump about:
t = 1.75 s
Alright, so the answer for:
3) is 3v + 4
Answer:
Step-by-step explanation:
So we have:
And we want to solve for π.
First, divide both sides by h:
Now, divide both sides again by r²:
And this is our answer :)
Answer:
75
Step-by-step explanation:
322 = 2(86) + 2w
322 = 172 + 2w
322-172 = 172 +2w -172
150 = 2w
150/2 = 2w/2
w=75
Swimming half way around implies half of the circumference.
Circumference = pi x diameter
C = pi x 20
C = 20pi
20pi / 2 = 10pi
You swam 10pi meters = 31.42 meters.
Hope this helps!! :)
