It would be c. y = x because if you plug in the numbers, it would be true
Answer:
2√2
Step-by-step explanation:
compare this equation with the standard equation of a circle centered at (h, k) with radius r:
(x - h)^2 + (y - k)^2 = r^2
(x - 5)^2 + (y + 7)^2=8
Clearly, r^2 = (radius)^2 = 8, and so the radius, r, is √8, or 2√2
Answer:
Step-by-step explanation:
because you started at 8 and the dots are going down
The answer is C. 89 in^2
This is found by (1/2(
))+70
r in this equation stands for radius which is half the diameter. Sice the diameter equals 7, the radius equals 3.5
You have to solve this by putting it into a calculator since you can't really solve for an equation with pi in it otherwise.
Hope this helps!
Answer:
x = 20
Step-by-step explanation:
The two angle are a linear pair. Their measures has a sum of 180 deg.
2x + 140 = 180
2x = 40
x = 20
