The correct option is (b) h=0.5cos(/6t)+9.5.
The equations can be used to model the height as a function of time, t, in hours is h=0.5cos(/6t)+9.5.
The following is a presentation of the cosine function's generic form;
y = a + cos(bx - c) + d
amplitude = a
b = cycle speed
Calculation for the model height;
The height, h (feet) of the tip of the hour hand of a wall clock varies from 9 feet to 10 feet.
Obtain amplitude 'a' as
The time 'T' is calculated as-
Now, calculate 'd'
Therefore, with the height as a function of time, t, expressed in hours, can be modeled by the following equations:
h=0.5cos(/6t)+9.5

The complete question is-
The height, h, in feet of the tip of the hour hand of a wall clock varies from 9 feet to 10 feet. Which of the following equations can be used to model the height as a function of time, t, in hours? Assume that the time at t = 0 is 12:00 a.m.
A. h=0.5cos(/12t)+9.5
B. h=0.5cos(/6t)+9.5
C. h=cos(/12t)+9
D. h=cos(/6t)+9
Answer:
Step-by-step explanation:
We are given that A rose garden can be planted for $4000.
The marginal cost of growing a rose is estimated to $0.30,
Let x be the number of roses
So, Marginal cost of growing x roses =
Total cost =
So, Cost function : ---A
Now we are given that the total revenue from selling 500 roses is estimated to $875
So, Marginal revenue =
Marginal revenue =
Marginal revenue =
Marginal revenue for x roses =
So, Revenue function = ----B
Profit = Revenue - Cost
---C
