The total revenue function if the revenue from 115 devices $2116 is 200 when R'(x)=4x(x²+25000[tex])^{2/3}[/tex].
Given that,
The following function calculates the marginal revenue (in thousands of dollars) from the sale of a portable gaming system.
R'(x)=4x(x²+25000[tex])^{2/3}[/tex]
We have to find the total revenue function if the revenue from 115 devices $2116.
We know that,
R'(x)=4x(x²+25000[tex])^{2/3}[/tex]
Integrating on both sides
R(x)= [tex]\int {4x(x^{2} +25000)^{2/3} } \, dx[/tex]
Let x²+25000=t
=> 2xdx=dt
=> 4xdx=2dt
We get,
R(x)= [tex]\int {2t^{-2/3} } \, dt[/tex]
R(x)= [tex]6t^{1/3}[/tex]+C
By Substitution then
R(x)= 6(x²+25000[tex])^{1/3}[/tex]+C
We get
Given R(115)=$2,116 or 2.116 (in thousands of dollars) and x=115 units
Then total revenue function(in thousands of dollars)
2.116= 6(115²+25000[tex])^{1/3}[/tex]+C
C=200
Therefore, The total revenue function if the revenue from 115 devices $2116 is 200.

A random sample of 64 sat scores of students applying for merit scholarships showed an average of 1400 with a standard deviation of 240. the 95onfidence interval for the population mean sat score is: ________
a. 1.96. b. 1.998.
c. 1.645. d. 1.28.
The 95% confidence interval for the population mean SAT score is given as follows:
(1340, 1460).
How to calculate the confidence interval?The confidence interval is calculated using the t-distribution, as the standard deviation for the population is not known, only for the sample.
The bounds are obtained according to the equation defined as follows:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
In which the variables of the equation are presented as follows:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.In the context of this problem, the values of these parameters are given as follows:
[tex]\overline{x} = 1400, n = 64, s = 240[/tex]
The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 64 - 1 = 63 df, is t = 1.998.
Then the lower bound of the interval is of:
1400 - 1.998 x 240/sqrt(64) = 1340.
The upper bound of the interval is of:
1400 + 1.998 x 240/sqrt(64) = 1460.

square pqrs has sides of length $4$, and $m$ is the midpoint of $\overline{rs}$. a circle centered at $m$ with radius $2$ intersects the circle centered at $p$ with radius $4$ at points $n$ and $s$. what is the distance from $n$ to $\overline{ps}$?
The distance between N and PS is 3.2.
What is the midpoint of the segment?
Take the distance between the two endpoints and divide it by two. This distance from either end is the line's midpoint. Alternatively, add the endpoints' x coordinates and divide by 2. Repeat for the y coordinates.
From the below figure,
N is the intersection of the red and blue circles.
I’ve drawn PQRS as the square (0,0), (4,0), (4,4), and (0,4).
Then the formula for the red circle is:
(x-2)² + (y-4)² = 4.
The formula for the blue circle is
x² + y²- 16 = 0.
Solving for x and y yields intersections
(0, 4) and (3.2, 2.4),
the first being S and the latter being N.
Hence, the distance between N and PS is 3.2.

The area of the triangle in the image is 1/20 square centimeters.
How to find the area of the figure in the image?This is a rather trivial problem.
On the image, we can see a triangle where the height and the base are known quantities.
Remember that for a triangle of height H and base B, the area is given by the formula:
A = B*H/2
Here we can see that:
H = (1/6) cm
B = (3/5) cm
Then we can replace these two fractions on the area formula, we will get:
A = (1/6 cm)*(3/5 cm)/2
A = (3/5*6 cm²)/2
A = (3/30*2 cm²)
A = (3/60 cm²) = (1/20 cm²)

How to find DE?For the given square we know that EC = 7x - 3 and AE = 4x + 8, notice that both EC and AE are half of a diagonal of the square, so these measures must be the same one, then we can write the linear equation:
7x - 3 = 4x + 8
solving for x:
7x - 4x = 8 + 3
3x = 11
x = 11/3
And DE is also half of the diagonal, so the measure of DE is the same than the measure of EC, then it is:
DE = 7x - 3 = 7*11/3- 3 = 22.67
