find the equation x^2 + y^2 + dx + ey + f = 0
of the circle that passes through the points. to verify your result, use a graphing utility to plot the points and graph the circle.
(0, 0), (8, 8), (16, 0)

D= -16

E= 0

F= 0

Step-by-step explanation:

The given equation is

It is also given that the circle passes through (0,0) (16,0) and (8,8).

Inserting (0,0) in the equation, it gives

This gives F = 0 .

Now inserting (16,0) , it gives

D = -16

Now inserting (8,8) , it gives

E = 0

Thus the equation of circle is

We can draw the following graph and thus verify that points (0,0) (8,8) and (16,0) lie on graph.

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
