1. The height of the tide in a small beach town is measured along a seawall. Water levels oscillate
between 7 feet at low tide and 15 feet at high tide. On a particular day, low tide occurred at 7:30 AM and
high tide occurred at 1:00 PM.
Write a cosine function of the form f(t) = A cos(Bt) + C, where A, B, and C are real numbers, that
models the water level, o), in feet above or below the average sea level, as a function of the time
measured in 7 hours since 7:30 AM

[10 points, algebra 2-simplifying complex fractions]according to my answer key the restrictions are -1 and 4. but why not positive 1?

Create a data set with 8 points in it that has a mean of approximately 10 and a standard deviation of approximately 1.

The cross-sectional areas of a right triangular prism and a right cylinder are congruent. the right triangular prism has a height of 6 units, and the right cylinder has a height of 6 units. which conclusion can be made from the given information? the volume of the triangular prism is half the volume of the cylinder. the volume of the triangular prism is twice the volume of the cylinder. the volume of the triangular prism is equal to the volume of the cylinder. the volume of the triangular prism is not equal to the volume of the cylinder.
