Answer:
750
Step-by-step explanation:
250
250 + 250 = 500
500 + 250 = 750
750 + 250 = 1000
1000 + 250 = 1250
Answer:

Step-by-step explanation:
You need the info of the graph to get the answer.
Equation of the circle centered on the origin is x²+y²=r²
r=5
x²+y²=5²
x² + y² = 25 ← answer
Answer: 40
Step-by-step explanation:
5*2^3 = ? // means comment btw, also I am on my iPad so * means times and ^ power like 2 to the 3rd power
5*2*2*2
(5*2)*(2*2)
10*4
Answer= 40
Let x, y, z ∈ C, the set of complex numbers.
By definition of ○,
(x ○ y) ○ z = (x + y - 2i) ○ z
… = (x + y - 2i) + z - 2i
… = x + y + z - 4i
and
x ○ (y ○ z) = x ○ (y + z - 2i)
… = x + (y + z - 2i) - 2i
… = x + y + z - 4i
so (x ○ y) ○ z = x ○ (y ○ z), which means ○ is indeed associative under C.
