A. Profit (P):
P = 100 x
Revenue (R) is Profit – Cost:
R = P – C
R = 100 x – [2750 + 8x + 0.1x^2]
R = 100x – 2750 – 8x – 0.1x^2
R = -0.1x^2 + 92x – 2750
B.
To make a profit, R must be zero, R = 0:
0 = -0.1x^2 + 92x – 2750
x^2 – 920x = - 27,500
Completing the square:
<span>x^2 – 920x + 211,600 = - 27,500 + 211,600</span>
(x – 460)^2 = 184,100
x – 460 = ± 429.07
x = 30.93, - 889.07
Therefore sell at least 31.
31<x<500

Answer:
Friend is not correct.
Step-by-step explanation:
<em>The complete question with image is attached.</em>
We need to find the angle and the point (0.8), or the angle created between the two lines.
First we need to find slope (m) of both the lines.
The slope (m) is change in y coordinates divided by change in x coordinates. Or
<u>Slope of line above:</u>
<u>Slope of below line:</u>
The formula to find angle between two lines is:
Where m_1 = -2 and m_2 = 2
Plugging in the values, we get:
Angle = 53
Hence, your friend IS NOT correct.

d. For →
Step-by-step explanation:
Since the variables "x" and "y" are inversely related, the equation has the following form:
Where "k" is the constant of variation.
In this case we know that:
So, the equation is:
Therefore, substituting the given values of "x" into the equation, we get:
a. For →
b. For →
