The line from (7, 1) to (-2 10) is a radius of the circle.
Its length is the square root of [ (-2 - 7)² + (10 - 1)² ] = √(81 + 81) = √162
The equation of the circle is: (x- 7)² + (y - 1)² = 162

Step-by-step explanation:
This equation shows the income obtained based on the number of boats sold. We want to know the minimum number of boats that must be sold to obtain $ 75 000.
Then we must equalize the equation to 75 000 and clear b.
3 solutions will be obtained (because it is a polynomial of degree 3), and the lowest value will be taken.
Now we need to solve the equation, for that we seek to factor the polynomial
we divide the equation by -25
We take common factor b
We take out common factor (b-30)
Finally the solutions are:
b = 10 and b = -10
We take the least positive solution (because you can not produce -10 boats)
Finally b = 10
The smallest number of boats that must be produced to make a profit of $ 75,000 is 10 boats.
You need to remember that 100 pence = 1 pound sterling.
Halve both sides: 50 pence = 1/2 pound sterling
200 pence = <span>£2
</span>
50 pence 50 pence
Thus 50 p/ <span>£2 = ------------------ = ------------------ = 1/4
</span>£2 200 pence
50 p is 1/4 of <span>£2.</span>
