Write the equation of the circle in general form.
if anyone can explain this that would be great, if not it's okay, just a little lost on how to do all of this haha

Step-by-step explanation:

The general equation of a circle is

In this equation, 'r' represents the radius of the circle and (h,k) represents the central point of the circle.

Radius of the circle is half of the diameter = d/2

From figure, ther diameter of the circle is calculated using (y2-y1) or (x2-x1)

In this figure,

y2 = 6

y1 = 2

d = (y2 - y1) = 6-2 =4

This can also be verified using the values of x

x2 = -1

x1 = -5

d = (x2 - x1) = (-1 - -5) = (-1 + 5) = 4

Also,

r = d/2 = 4/2

r = 2

h represents the horizental distance and k represents the vertical distance of the center of the circle from the origan (0,0).

Therefore,

h = 0 - 3 = -3 as the center of circle is 3 units left to the origan

k = 0 + 4 = 4 as the center of circle is 4 units above to the origan

Therefore the equation of circle becomes

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )
