The quantity of Sensitech laser gaming mice demanded each month is related to the unit price by the equation p = 480.03x2 + 1 (0

stich3 [128]

Answer: a) $p=480.03x^2+1$ , b) $R'(x)=1440.09x^2+1$ c) $5761.36.

Step-by-step explanation:

Since we have given that

Unit price is expressed as

$p=480.03x^2+1$

Let x be the number of units of a thousands.

So, Revenue function is given by

$R(x)=px\\\\R(x)=x(480.03x^2+1)\\\\R(x)=480.03x^3+x$

.(b) Find the marginal revenue function R'..

Marginal revenue function becomes,

$R'(x)=3\times 480.03x^2+1\\\\R'(x)=1440.09x^2+1$

(c) Compute R'(2).

$R'(2)=1440.09(2)^2+1\\\\R'(2)=5760.36+1\\\\R'(2)=5761.36$

Hence, a) $p=480.03x^2+1$ , b) $R'(x)=1440.09x^2+1$ c) $5761.36.

A worker at a snack stand opened a new box of cups. On the first day, the worker used 30 cups from the box. On the second day, t

Solnce55 [7]

Answer:

Step-by-step explanation:

<u>Percentages</u>

This problem is most easily solved backward, i.e., from the final data up to the beginning.

There was a new box of cups and the worker at a snack stand opened it. He first used 30 cups from the box and the second day he uses 15% of the remaining cups in the box, and we are told that represents 90 cups.

If 15% (0.15) equals 90 cups, then the number of cups before the second day was 90/0.15 = 600 cups.

On the first day, we used 30 cups, thus the original number of cups in the box was 600+30=630 cups

Answer:

For $\frac{6}{25} = \frac{d}{30}$ , d = 7.2

Step-by-step explanation:

Here, the given expression is $\frac{6}{25} = \frac{d}{30}$

To find the value of the variable d :

$\frac{6}{25} = \frac{d}{30} \implies d = \frac{6}{25} \times 30$

or, $d = \frac{180}{25} = \frac{36}{5 } = 7.2$

Hence, for $\frac{6}{25} = \frac{d}{30}$ , d = 7.2
