Answer:

(a) $R(x)=-0.02x^2+610x$

(b) $R'(x)=-0.04x+610$

(c)R'(5400)=$394

Step-by-step explanation:

Given that x is the quantity demanded and the speaker's unit price (in dollars) is p where:

p = −0.02x + 610 (0 ≤ x ≤ 20,000)

(a)Revenue function R.

Revenue = Price X Quantity Demanded

Therefore:

R(x)=xp

$=x(-0.02x + 610)\\R(x)=-0.02x^2+610x$

(b)Marginal revenue function R'(x)

If $R(x)=-0.02x^2+610x$

Then, the marginal revenue function

$R'(x)=-0.04x+610$

(c)We want to compute R'(5,400)

$R'(5400)=-0.04(5400)+610\\R'(5400)=394$

From the above, we can infer that the revenue that will be generated on the sales of the 5401st item is $394.

Which is better: Car A that travels 308 miles on 11 gallons of gasoline OR Car B that travels 406 miles on 14 gallons of gasolin

Jet001 [13]

$\begin{gathered} \text{Car A travels 308 miles on 11 gallons, so, the ratio of miles per galon is} \\ \frac{308}{11}=28\text{ miles per gallon} \\ \\ \text{for the car B, the ratio is} \\ \frac{406}{14}=29\text{ miles per gallon} \end{gathered}$

thus, the best car is car B,because it can tavel 29 miles with only one gallon,andcar A can only travel 28 miles with one gallon.

If log(16)=s, what is the value of 2/3 log(6400) - 1/3 log(1600) in terms of s?

eduard

The value of $\dfrac{ 2}{3} log(6400) - \dfrac{1}{3} log(1600)$ in terms of s will be

$\dfrac{2}{3}(400s)-\dfrac{1}{3}(1000s)$

<h3>What is Logrithm?</h3>

A quantity representing the power to which a fixed number (the base) must be raised to produce a given number.

Here we have the expression:-

$\dfrac{ 2}{3} log(6400) - \dfrac{1}{3} log(1600)$

So in terms of s the expression will become:-

$\dfrac{2}{3}(400s)-\dfrac{1}{3}(1000s)$

What is the correct answer?

Nutka1998 [239]

Answer:

D) 8

Step-by-step explanation:

You multiply 10 by 12 to get 120 so you multiply x by 12 to get 96.

96 = 12x

/12 /12

8 = x
