lukranit [14]2 years ago
3 0

Answer:

15

Step-by-step explanation:

Just substitute the x for 5
In this case:

Original function: f(x) = x^{2} - 2x

Substitute function: f(5) = (5)^{2} - 2(5)

Now solve for the substitute function

(5)^{2} - 2(5)

25 - 10

15

Therefore, f(5) is equal to 15

The quantity demanded each month of the walter serkin recording of beethoven's moonlight sonata, manufactured by phonola media,
Olenka [21]
We can get the Profit function P(x) from the Hint. 

the Profit function is: P(x) = xp(x) - C(x) = -0.00041 x2 + 4x - 600
Attention: don't get confuse by the <span>big P of the profit with the small p of the price</span> To calculate the maximum profit, we need to find the derivative of P(x) then set it to 0 then find x: dP(x)/dx = -0.00082 x + 4 = 0 ,   so x = 4/0.00082 = 4,878 copies each month.

Ted and Meg have each drawn a line on the scatter plot shown below:
expeople1 [14]

Answer:

A.)Line P, because it is closest to most data points

Step-by-step explanation:

The line of best fit is a line which best represents the data and the data points are closely related to it.

It is also known as a trend line.

The line of best fit may pass through, some , none or all of the data points.

Also if the scatter plot does not pass through all the data point then the magnitude of positive residual must be approximately equal to the magnitude of negative residual of the data points.

Hence, by looking at the scatter plot we see that all the data points lie above Line R.

Hence, the Line R will not be a line of best fit.

But all the data points lie close to the line P , hence it act as a line of best fit.
