Find the geometric mean for 8 and 18

Mathematics
1 answer:
Gekata [30.6K]3 years ago
8 0
<h3>Answer:   12</h3>

======================================================

Work Shown:

z = geometric mean of x and y

z = sqrt(x*y)

z = sqrt(8*18)

z = sqrt(144)

z = 12

The geometric mean of 8 and 18 is 12.

The geometric mean is similar to the arithmetic mean; however instead of add up the values and divide by n, this time we're multiplying the values and then applying the square root. This only applies if we are finding the geometric mean of 2 values. If you have more values, then you'll need to take higher order roots.

Eg: if you had 3 values, then you would need to take a cube root. Four values needs a fourth root, and so on.

Between x = 2 and x = 3, which function has a greater average rate of change than y = 13 -x ?
Marrrta [24]
For this case what you should know is that the slope of the line can be calculated as:
 Tan x = sin x / cos x
 The lines x = 2 and x = 3 have an angle of 90 degrees with respect to the x axis:
 Tan 90 = sin 90 / cos 90 = 1/0 = inf
 Therefore, both lines have a rate of change that tends to infinity.
 answer
 Both lines have the same slope (infinity) Both are greater than m = -1

Elena-2011 [213]

Answer:

v=5.42m/s

Step-by-Step Explanation:

We can use conservation of energy to solve this  

mgh=1/2mv^2

2gh=v^2

v=sqrt(2gh)

v=sqrt[2*9.8m/s^2*(6.5-5)]

v=5.42m/s
