The correct true statement is the swimmer comes back up 9 seconds after the timer was started.
<h3>Maximum height of a function</h3>
The maximum height of a function is the point where the velocity the body is zero.
Given the function that represent the height of the swimmer as h(t)=t^2−12t+27
If the velocity of the function is zero, hence;
h'(t) = 2t - 12
0 = 2t - 12
2t = 12
t = 6secs
Substitute t = 6 into the function as shown:
h(6) = 6^2−12(6)+27
h(6) = 36 - 72 + 27
h(6) = -36 + 27
h(6) = -9 feet
Hence the correct true statement is the swimmer comes back up 9 seconds after the timer was started.

Area = length x width
323 = 19 x w
323 = 19w
Divide both sides by 19
<u>323</u> = <u>19</u> w
19 19
w = 17 feet
