Step-by-step explanation:
Assuming this complete problem: "A cell tower is located at (-8, 4) and transmits a circular signal that covers three major cities. The three cities are located on the circle and have the following coordinates: G (-4, 7), H (-13, 4), and I (-8, -1). Find the equation of the circle"
For this case the generla equation for the circle is given by:
From the info we know that the tower is located at (-8, 4) so then h = -8 and k = 4, so then we need to find the radius. So we have the equation like this:
If the 3 points are on the circle then satisfy the equation. We can use the first point (-4,7) and if we replace we can find the value for
So then
And if we replace the second point we got this:
And for the third point we have:
And we got the same result.
So then our final equation is given:
Answer:
900 Large Fish
1500 Fish Total
Step-by-step explanation:
The 2:3 ratio means that for every 2 small fish sold, 3 large fish are sold.
We can divide 600 by 2 and then multiply by 3 to find our answer.
To check our answer, we can put it into the form of a fraction and see if it simplifies back to that ratio.
We have confirmed 900 is the correct number of large fish. To answer the second part of the question we just have to add the two numbers together.
So, our two answers are
900 Large Fish
1500 Fish Total
