What is the geometric mean of 40 and 15?

1 answer:

6 0

You would do 40/x=x/15, therefore you get x^2=600. to find x you find the square root of each side. Rounded to the nearest tenth, you get 24.5. If you put it in simplest radical form you should get 10 times the square root of 6

Answer:

Square Root of 162 ~ 12.727

Step-by-step explanation:

Simply do the Pythagorean Theorem!

a^2 + b^2 = c^2

This case we're solving for the long side which is the hypothenuse.

9^2+9^2= c^

81+81=c^

162=c^

Square root of 162

Which is 12.727

A(-2,3) B(2,3) C(2,-3) D(-2,-3) Math question please help

The number on the left is the x, and the number on the right is the y. so if the x is negative, then it would be on the x axis line. and you always use the x line first.

natka813 [3]

Answer:

Step-by-step explanation:

When evaluating absolute values, a great way to remember what they do is simple. No matter the number, whether it is negative or positive, the number(s) IN THE absolute values are ALWAYS positive.

So, |x + y| is then substituted with the numbers given for the variables.

|x + y|

|8 - 15|

|-7|

A regular square pyramid has a base length of 6 cm. the slant height of the pyramid is 9 cm. what is the surface area of the reg

PolarNik [594]

So..hmm check the picture below

the pyramid is really just 4 triangles and 1 square at the bottom, all stacked up to each other at the edges

get the area of the square bottom, is just a 6x6 square, thus the name of the pyramid

and get the area of each triangle, notice the base is 6, the altitude or height is 9

and add them all up, that's the surface area of the pyramid
