Find the radius and center of the circle
17+x^2+y^2-8x-6y=0

Centre: (4,3)

Radius: 2sqrt(2)

Step-by-step explanation:

h = -8/-2 = 4

k = -6/-2 = 3

4² + 3² - 17 = r²

r² = 8

r = sqrt(8) or 2sqrt(2)

sqrt: square root

what's that

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
