The geometric mean of 9 and 15

The geometric mean of 9 and 15 is 11.62

Given two integers A and B, the geometric mean of the integers is expressed as:

GM = √A×B

Given the values 9 and 15, the geometric mean of the values is expressed as:

GM = √9×15

GM = √135

GM = 11.62

Hence the geometric mean of 9 and 15 is 11.62

Step-by-step explanation:

Geometric mean can be calculated like such:

a/x = x/b

Where a and b are your 2 numbers. By solving for x by cross-multiplying you get:

x^2=ab

So to solve for geometric mean, all you have to do is to multiply the two numbers and take the square root:

9(15)=135

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
