Find the center and radius of the circle with equation (x + 3)^2 + (y + 6)^2 = 16

The center is at (h, k):  (-3, -6)  and the radius is r = 4.

Step-by-step explanation:

Compare the given (x + 3)^2 + (y + 6)^2 = 16 with the standard equation of a circle                         (x - h)^2 + (y - k)^2 = r^2.

We can see immediately that h must be -3, k must be -6 and r must be 4.

The center is at (h, k):  (-3, -6)  and the radius is r = 4.

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
