Step-by-step explanation:
At the elevation 617.5 feet below the sea level temperature of the water was °F
Step-by-step explanation:
At 502.5 feet below the sea level temperature of the water is °F
When submarine dives down 115 feet deeper, water temperature drops by °F
Elevation after the submarine dove = -502.5 - 115 = -617.5 feet
This negative sign represents the elevation below the sea level.
And the temperature will be = 
= 
= 
= 
= °F
Therefore, at the elevation 617.5 feet below the sea level temperature of the water was °F

B. V=9
Multiply it out, then subtract 99 from both sides, then divide by 11
The amplitude and the period of the function are 3 and 2, respectively.
<h3>What are the amplitude and the period of a sinusoidal function?</h3>
Sinusoidal functions are periodic bounded functions whose form is described below:
y = A · sin (2π · t / T + Ф) + y'
Where:
- y' - Midpoint
- A - Amplitude
- t - Time
- Ф - Phase
- T - Period
The period is the horizontal distance between two consecutive peaks or two consecutive bottoms and the amplitude is equal to the half of the distance between a peak and a consecutive bottom. Hence, the amplitude and the period are, respectively:
Amplitude
A = 0.5 · [2 - (- 4)]
A = 3
Period
T = 2 · [0.75 - (- 0.25)]
T = 2
