The standard equation of the circle is:
(x-h)^2+(y-k)^2=r^2 where (h,k) it the center of the circle and r is the radius...
so
30.
(x-2)^2+(y-7)^2=16
31.
We need to find the radius...(I'll just use the Pythagorean Theorem)
r^2=6^2+8^2
r^2=36+64
r^2=100 (so the radius is 10) and its center is (-6,-8) so
(x+6)^2+(y+8)^2=100
Answer:
B i think
Step-by-step explanation:
The product of 1 and any number is the number (hence why it is most likely b). But instead of it being 4, it would be -4 because multiplying a negative by a positive results in a negative.
Answer:
He will spend $560 in 8 weeks
Step-by-step explanation:
So 260 for every 3 weeks how much will he make in 8 weeks
so 240+ 240
cause he makes 240 every 3 weeks
so he will make 480 in 6 weeks.
then to get how much he makes in 1 week you divide 240 into 3
so 240 divided by 3 equals 80 So he makes 80 in 1 week.
So 240+240+80=560
So he make $560 in 8 weeks
