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

For each equation given below, write ONE related equation. a) x + 5 = 18 b) 66x =330

GenaCL600 [577]

Answer:

x = 13 ; x = 5

Step-by-step explanation:

The easiest related equation to get is simply solving for x:

a) x + 5 = 18

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 5 from both sides:

x + 5 (-5) = 18 (-5)

x = 18 - 5

x = 13*

b) 66x = 330

Isolate the variable, x. Divide 66 from both sides of the equation:

(66x)/66 = (330)/66

x = 330/66

x = 5*

*Note: An equation simply is a expression that has an equal sign. This means that as long as there is an equal sign, it counts as an equation.

Please help!

Answer:

D. Subtraction property of equality

B. 6.5

Step-by-step explanation:

First blank:

The equation is x + 6.5 = 13.

To solve the equation, you want x alone on the left side, showing "x = some number." Since 6.5 is being added to x, you need to SUBTRACT 6.5. You must do the same operation to both sides of an equation, so you need to SUBTRACT 6.5 from both sides of the equation. What allows you to subtract the same number from both sides of an equation is the

<em>D. Subtraction property of equality </em>

Second blank:

Subtract 6.5 from both sides.

x + 6.5 = 13

x + 6.5 - 6.5 = 13 - 6.5

x = 6.5
