diameter is 15 meters then radius is 15/2 = 7.5 meters
so the amplitude is 7.5 m and height will oscillate with amplitude 7.5 m above and below the center.
midline of the oscillation will be 7.5 m
the wheel.take 8 minutes to complete revolution then it means the height will oscillate with a period of 8 minutes

Answer:
a) 4
b) 3
Step-by-step explanation:
a. The total number of real and complex zeros is equal to the degree of the polynomial. That total is (1 negative real) + (3 positive real/complex) = 4 total zeros. The degree of the polynomial is 4.
The even degree is confirmed by the answer to part b, and by the end-behavior shown in the table, which has a tendency to -∞ for |x|→∞.
__
b. The intermediate value theorem tells you there will be zeros in the intervals (0, 1), (1, 2), and (2, 3) according to the values in the table. (The function changes sign in those intervals.) Thus there are 3 positive real zeros.

<em>Additional comment</em>
Stanley cannot tell anything about Descartes' rule of signs by analyzing the table of function values. To use that rule, he must have terms of the polynomial. If he has those terms, he already knows the degree of the polynomial.
If you would like to know who paints the largest part of the fence, you can calculate this using the following steps:
three sections of the fence ... 3 sections
four equal sized boards ... 4 boards
3 * 4 = 12 boards
Alex: 1/6 of 12 boards = 1/6 * 12 = 2 boards
Bobby: twice as much as Alex = 2 * 2 boards = 4 boards
Charles: 1 board
David: 12 - 2 - 4 - 1 = 5 boards
Result: The largest part of the fence paints David (5 boards).
Price per hour of first case :
( Here, a is number of hours )
Price per hour of second case :
( Here, b is number of hours )
Let, after x hours both company charges the same.
Hence, this is the required solution.
Let O be the amount of orange juice and W be the amount of water.
A)
O = 0.8W
B)
W = 1, so:
O = 0.8(1)
O = 0.8 Liters
