Find the center and radius of the circle with the equation:

center(5,-1)

radius 2

Step-by-step explanation:

circle equation (x-a)²+(y-b)² = r² has radius r and center (a,b)

a = -(-5), b = -(1)

center = (5, -1)

r = √4 = ±2

since radius length cannot be negative, r = 2

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
