Answer:
Revenue = $452.2
Step-by-step explanation:
Given,
The selling price of a calculator, P = $16.15
The given equation is R = 16.15*q
We know that, Revenue = Price*Quantity
If the selling numbers of calculators is 28,
according to the question,
Revenue = $16.15*28
Revenue = $452.2
That is an example of a linear equation. In this equation, if we increase the quantity sold, the revenue will increase automatically.
Answer:
Hey there!
First, we want to find the radius of the circle, which equals the length of line segment AC.
Length of line segment AC, which we can find with the distance formula: , which is equal to 5.
The equation for a circle, is: , where (h, k) is the center of the circle, and r is the radius.
Although I don't know the center of the circle, I can tell you that it is either choice B or D, because the radius, 5, squared, is 25.
Hope this helps :) (And let me know if you edit the question)
