Answer:
r = √14
Step-by-step explanation:
Is this what you meant? If so heres' the answer
Equation of circle
Center the origin
r = √14
We know the solutions of x because we know the 2 x intercepts which are (0,0) and (5,0).
The association between flow rate and amount of eroded soil is positive because as the flow rate increases the amount of eroded soil also increases.
To find the length of a line between two points with known x- and y- coordinates, use:
sqrt((change in x)^2 + (change in y)^2),
which I know may look confusing but it isn't really:
sqrt((5 - -3)^2 + (4 - -1)^2)
= sqrt(8^2 + 5^2)
= sqrt(64 + 25)
= sqrt(89)
