which of the following is equivalent to the expression below? log3 - log15 A) log(-12) B) log12 C) log(1/5) D) log5 thanks for the help : )

Step-by-step explanation:

First and foremost, we need to point out that if there is no base written on those logs, it is understood to be a base of 10. The next thing applies to the rules of logs in regards to the subtraction of them. Usually, subtraction and addition "undo" each other. But in logs, subtraction and division undo each other in a sense. The rule is:

Following that pattern, our solution, or simplification, of

log(3) - log(15) is

which, simplified and omitting the base of 10, is:

, choice C.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

pi x^2

step-by-step explanation:

pi times x squared
