Rebecca is climbing up a 500-foot cliff. By-1:00 P. M., she has climbed 125 feet up the cliff. By 4:00 P. M., she has reached
an altitude of 290 feet. Find the average rate of change in
Rebecca's altitude during the three hours. Give the rate in feet
per hour.

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
