circumference of circle= 2x3.14r
1) radius is 9
2x3.14x9
18x3.14= 56.52
2) radius is 8
2x3.14x8
16x3.14= 50.24
3) radius is 5
2x3.14x5
10x3.14= 31.4
The complex number is represented as 2 + 3i. The conjugate of the complex number is the number with equal real part and imaginary part equal in magnitude but opposite in sign. Therefore, the correct answer is option B. The conjugate of the complex number is 2 − 3i.
Domain: {-4, -2, 0, 2, 4}
range: {-2, -1, 0, 1, 2}
I believe it's 3.75 x 10^5 (Sorry if I'm wrong)
