A rectangle is 6 ft long and 11 ft wide. What is the length of the diagonal of the
rectangle?

sqrt(157) ft is the length of the diagonal

Step-by-step explanation:

We can use the Pythagorean theorem to find the length of the diagonal

a^2 + b^2 = c^2

6^2 + 11 ^2 = c^2

36+ 121 = c^2

157 = c^2

Take the square root of each side

sqrt(157) = sqrt(c^2)

sqrt(157) = c

The equation of the midline is y=4.

the midline is the line that the function oscillates around. basically, the average of the maximum and the minimum will get you the midline. eyeballing it, it looks like the function revolves around the horizontal line y=4.

the distance between the midline and the maximum is the same as the distance between the midline and the minimum.
