What is the geometric mean of 10 and 40

Varvara68 [4.7K]

the geometric mean is 20

the geometric mean of 2 numbers a and b is $\sqrt{ab}$

$\sqrt{10(40)}$ = $\sqrt{400}$ = 20

a rectangular room is 4 times as long as it is wide and it's perimeter is 60 meters find the dimension of the room

olya-2409 [2.1K]

To answer this problem we have to use two different variables. For example...

L = Length

W = Width

So we know that the definition of perimeter is

L + L + W + W (or all the sides added up)

Now we also know that The Length is 4 times longer than the width.

So we can write 4W to replace the L

So in the given equation we set up Replace every L with 4W

4W + 4W + W + W = 60 meters

now group our W's

10W = 60 divide both sides by 10 to get W to be alone

÷10 = ÷10 It cancels on the left side and we solve on the right side.

W = 6

So now that we know what the width equals we can find what the length equals .

Remember this?

4W = L (plug in 6 for W)

4(6) = L

So L = 24

Our dimensions of this rectangle are length 24, width 6.

Good Luck! :)

Many doctors rely on the use of intravenous medication administration in order to achieve an immediate response of a particular

rewona [7]

The domain of the function is 0 ≤ t ≤ 3 and the greatest concentration of the medication is 2mg/L

<h3>The domain of the function</h3>

The equation of the function is given as:

$C(t) = \frac{-18t^2 + 54t}{t^2 + 7t + 10}$

Time can be 0 or greater but cannot be negative.

So, the domain of the function includes t ≥ 0

Set the function to 0 to determine the maximum value of t.

$\frac{-18t^2 + 54t}{t^2 + 7t + 10} = 0$

Cross multiply

$-18t^2 + 54t = 0$

Factor out -18t

-18t(t - 3) = 0

Divide both sides by -18t

t - 3 = 0

Add 3 to both sides

t = 3

This means that the maximum value of t is 3

Hence, the domain of the function is 0 ≤ t ≤ 3

<h3>The greatest concentration of the medication</h3>

From the graph of the function (see attachment), we have the maximum value to be;

C(t) = 2

Hence, the greatest concentration of the medication is 2mg/L
