H (t) = - 16t ^ 2 + 16t + 480
For this case, the first thing to do is to match the polynomial to zero to find the roots.
We have then:
0 = -16t ^ 2 + 16t + 480
From here, we obtain the following roots of the polynomial:
t1 = -5
t2 = 6
We ignore the negative root because the time is always greater than zero.
Answer:
it takes Rose to hit the water about
t = 6 seconds
Answer:

We can tell from the data that there is a midpoint between the lowest and highest point of the clock, which is at a height of 9.5 feet.
Moreover, the lowest point occurs at 6 o clock, and the highest occurs at 12 o clock.
The amplitude of variation from the mid-point is 0.5 feet given by (10 - 9) / 2.
Finally, the time period for the equation is 12 hours. Thus, the answer is:
h = 0.5cos(πt/6) + 9.5, option B
Answer:
P = 2(21 + 3)

Step-by-step explanation:
Add them all up.
s + 2(s+3) + 4s-5 = 148
s + 2s + 6 + 4s - 5 = 148
Group all s together and all numbers together 7s + 1 = 148
7s = 147
Divide by 7
s = 21
Plug s=21 back in for Petro
Answer:
It represents a mosquito that flew very fast after feeding relative to all other mosquitoes.
Step-by-step explanation:
The point is unusual because the velocity of the mosquito is substantially greater than all other velocities and is probably an outlier.
