Question: The blades of a windmill turn on an axis that is 40 feet from the ground. The blades are 15 feet long and complete 3 rotations every minute. Write a sine model, y = asin(bt) + k, for the height (in feet) of the end of one blade as a function of time t (in seconds). Assume the blade is pointing to the right when t = 0 and that the windmill turns counterclockwise at a constant rate.
Answer:
a is the length of the blade.
The vertical shift, k, is the height of the windmill.
a = 15
k = 40
The period is 20 seconds.
b = pi/10

Hormone therapy reduces the interaction of hormones with (D), cancer cells.
Hormone therapy is a type of cancer treatment that uses hormones to reduce the growth of cancer cells. Hormones are chemicals that are produced by the body and that regulate many different functions, including growth, development, and reproduction.
Cancer cells often need hormones to grow and spread. Hormone therapy works by blocking the interaction of hormones with cancer cells. This can help to slow the growth of cancer cells or even kill them.
The answer must be something that interacts with hormones. Of the above choices, only cancer cells interact with hormones. So the answer is (d).
