The center is at origin O(0,0).
If it contains the point, P(-8,6), then the radius r is, by Pythagoras theorem,
r=sqrt((-8)^2+6^2)=10
The general equation of a circle at centre (xc,yc) with radius r is given by
(x-xc)^2+(y-yc)^2=r^2
Substituting r=10, (xc,yc)=(0,0)
the resulting equation is therefore
(x-0)^2+(y-0)^2=10^2
or simply
x^2+y^2=100
15 pounds each and 16 watermelons= 240 pounds. (15x16=240)
The right way to find slope would be to use the rise/run method. For instance for the bottom line take the first dot, rise 7 and run to the right 6. So your slope for the bottom line is 7/6. Now do the same for your top line. I'll start at the bottom dot 6 and run right 6. If your slopes are the same that'd mean they were parallel. So no they are not parallel
Answer: 30 feet
Explanation:
Draw a vertical number line.
Mark +20 or simply 20 which is the starting position at the diving board. The value 0 on the number line is the water's surface. The position -10 is the portion 10 feet at the bottom of the pool.
Going from 20 to 0 is 20 feet. Then going from 0 to -10 is another 10 feet.
Overall, you travel 20+10 = 30 feet.
