The average rate of change of g(x) between x = 4 and x = 7 is 5/6. which statement must be true?
a. g(7)-g(4)=5/6
b. g(7-4)/7-4=5/6
c. g(7)-g(4)/7-4=5/6 d. g(7)/g(4)=5/6

So it looks like C.

Step-by-step explanation:

Average rate of a function g(x) on the interval from x=a to x=b is given by the formula:

.

You can even say:

.

So we have from x=4 to x=7, so the formula becomes:

We are given this is equal to 5/6.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

hello! just here for points! though i wish i knew!
