Answer: 29 feet (deepest) at 6 am
21 feet (shallowest) at Midnight & Noon
<u>Step-by-step explanation:</u>
y = -4 cos (π/6)t +25
Amplitude (A) = 4
-A means it is a reflection over the x-axis (starts at minimum)<em> </em>
Period = 2π/B → Period = 12
Phase shift = C/B → Phase Shift = 0
Midline (D) = 25
Midline (D) ± Amplitude (A) = Max & Min
Max: 25 + 4 = 29
Min: 25 - 4 = 21
Change the coordinates of y = cos (x) as follows:
- x-value: Add C then divide by B
- y-value: Multiply by A then add D
Note that the equation shows: A = -4, B = π/6, C = 0, D = 25
The answer is C. $1,600 because you multiply 200 by the cost of the ticket.
The height of the object after 5.5 seconds is 394.875feet
<h3>Functions and values</h3>
Given the function that represents the height of the ball as shown:
In order to determine the height of the object after 5.5 seconds, we will substitute t = 5.5s into the formula to have;
Hence the height of the object after 5.5 seconds is 394.875feet

Answer: The required expression she is on after d days is 
Step-by-step explanation:
Since we have given that
Page number at which she is = 88
Number of pages she will read every day = 20
Let the number of days be 'x'.
According to question, it becomes
Hence, the required expression she is on after d days is
