You purchase an iPhone for $599 a case for $49 and a charging station for $61. You charge it to your credit card annual interest rate of $19. How much interest will you have to pay if you take 3 years to pay off the bill?

$404.13

Step-by-step explanation:

First, you start by adding together 599, 49, and 61, which gives you 709. Then, you want to do 709(1.19) to find the amount he would pay including interest in a year, and your answer is 843.71. You want to next subtract that by 709, so you do 843.71-709, and get 134.71. Finally, since it says 3 years, you have to multiply that by 3, and 134.71(3) gives you your final answer, $404.13. I hope this helped you understand better!

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

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
