Answer:

The answer is: -2.

Step-by-step explanation:

Note when x = -2 that the line passes through the point (-2, -2) so when x = -2 then y also = -2.

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

(x - 4)² + y² = 16

Step 02:

polar form:

x = r cos (θ)

y = r sin (θ)

(r cos (θ) - 4 )² + (r sin (θ))² = 16

(r cos θ - 4)² + r² sin² θ = 16

r (r - 8 cos (θ)) = 0

r = 8 cos θ

The answer is:

r = 8 cos θ

How do the different values of h,k,and r change the graphs of the circles?

serious [3.7K]

Answer:

See Below

Step-by-step explanation:

The standard form of an equation of a circle is:

$(x-h)^2+(y-k)^2=r^2$

and

(h,k) is the center

r is the radius

Changing the values of h and k changes the location of the center of the circle. Changing the value of r changes the radius and hence the "size" of the circle. Very simple!

So, basically changing h and k translates the circle elsewhere and changing r transforms (make larger or smaller) the circle!
