Assume that the profit generated by a product is given by where x is the number of units sold. If the profit keeps changing at a

rate of per month, then how fast are the sales changing when the number of units sold is 1100? (Round your answer to the nearest dollar per month.) $30/month $132,665/month $16,583/month $33,166/month

Answer:

P'(1100)=0.06

(see explanation below)

Step-by-step explanation:

<em>The answer is incomplete. The profit function is missing, but another function will be used as an example (the answer will not match with the options). </em>

<em>The profit generated by a product is given by </em>P=4\sqrt{x}<em>.</em>

The changing rate of sales can be mathematically expressed as the derivative of the profit function.

Then, we have to calculate the derivative in function of x:

\dfrac{dP}{dx}=\dfrac{d[4x^{0.5}]}{dx}=4(0.5)x^{0.5-1}=2x^{-0.5}=\dfrac{2}{\sqrt{x}}

We now have to evaluate this function for x=1100 to know the rate of change of the sales at this vlaue of x.

P'(1100)=\frac{2}{\sqrt{1100} } =\frac{2}{33.16} =0.06

Answer:

  (W, T, L, S) = (3, 2, 1, 4.1)

Step-by-step explanation:

For some number of wins (W), ties (T), and losses (L), the player's score will be ...

  score = 2.2W +0.25T -3L

For 3 wins, 2 ties, and 1 loss, the player's score is ...

  2.2(3) +0.25(2) -3(1) = 6.6 +0.5 -3 = 4.1

Write a compound inequality that the graph could represent.
Dmitry_Shevchenko [17]
A solid dot on the graph of an inequality indicates that the number is contained within the inequality, so yo should use \leq or \geq to represent that situation, whereas a white dot indicates that the number is not contained within the inequality. 

Our graph is telling us that x is greater or equal than -1, and also x is less than 3. So our inequality will be:

-1 \leq x \leq 3

What is 27 is what % of 60?
natta225 [31]
Let 27 be x% of 60

so,
x/100 *60 = 27
x = 27*100/60 = 270/6 = 45

So,
27 is <em>45%</em> of 60.
