Knowing that you use 275 KWH from 7 a. m. – 7 p. m. and 265 KWH from 7 p. m. – 7 a. m., answer the follow question using the chart below.

Constant Usage $0.06624/KWH
Daytimer (Most usage between 7 a. m. – 7 p. m.)

As long as most power used is 7 a. m. – 7 p. m., then you receive a 20% discount on power usage 7 p. m. – 7 a. m.

$0.06831/KWH
NightTimer (Most usage between 7 p. m. – 7 a. m.)

If more than 50% of power usage is outside of 7 p. m. – 7 a. m., then you have to pay the Daytimer rate for all power used 7 a. m. – 7 p. m.

$0.06445/KWH

How much have you paid on the NightTimer plan?

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
