If Chad can paint the whole room in 5 hours, in 1 hour he gets 1/5 of it painted.  If Cassie can paint the whole room in 3 hours, in 1 hour she gets 1/3 of it painted.  If we add those together we can find out how much of the room they can paint together in one hour.  1/5 + 1/3 = 1/x, with x being the number of hours it will take them to paint the room together.  Common denominator is 15, therefore, 3/15 + 5/15 = 1/x and 8/15 = 1/x.  Cross-multiply to get 8x = 15, so it will take them 15/8 hours, or 1.9 hours to paint the whole room together.

Determine the center and radius of the following circle equation:
ioda

Answer:

C(5,-9) and r=8.

Step-by-step explanation:

C(p, q) - center

r=radius

k:x^2 +y^2 +dx+ey+f=0

x^2+y^2 - 10x+18y+42=0

d=-10, e=18, f=42

p=-d/2=-(-10)/2=10/2=5

q=-e/2=-18/2=-9

r^2 =p^2+q^2-f

r^2 =5^2 +(-9)^2 - 42

r^2=25+81-42

r^2 =106-42

r^2 =64

r=sqrt(64)

r=8

C(p,q)=C(5,-9) r=8
