Answer: Okay...what's your question?
Step-by-step explanation:
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
Answer:
Step-by-step explanation:
Let x represent the number of hours that Justin works in a week.
Let y represent the total amount that Justin would receive for working for x hours.
Justin earns $8 an hour for the first 40 hours he works and $12 for each additional hour. This means that the total amount that he earns in a week would be
y = 8×40 + 12(x - 40)
y = 320 + 12(x - 40)
If he earns 48 hours in a week, the total amount that he earned would be
320 + 12(48 - 40) = $416
