Answer:
none :)
Step-by-step explanation:
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.

No because they're two separate shapes of different porportions. one is 5 cm x 9 cm and the other is 3 x 7 they're not similar. It's hard to explain but a shape that was 10 cm x 30 cm would be similar to the same shape that was 1 cm x 3 cm's.
BDC is adjacent (Two angles are Adjacent when they have a common side and a common vertex (corner point) and don't overlap.)
Answer:
Scale 1: 1 centimeter = 3 meters.
Scale 2: 1 centimeters = 4 meters.
