Option 2 8-12i is correct.
Step-by-step explanation:
The conjugate of the complex number is obtained by changing the sign of the imaginary part.
In complex number 8+12i
8 is the real part and 12i is the imaginary part
The conjugate of 8+12i is 8-12i
So, Option 2 8-12i is correct.

Answer:
4.647 to the nearest thousandth.
Step-by-step explanation:
The formula for the length of an arc between x = a and x = b is
a
∫ √( 1 + (f'(x))^2) dx
b
Here f(x) = √x so
we have ∫ (√( 1 + (1/2 x^-1/2))^2 ) between x = 0 and x = 4.
= ∫ ( √( 1 + 1/(4x)) dx between x = 0 and x = 4.
This is not easy to integrate but some software I have gives me the following
length = √17 + 1/8 log(33 + 1/8 √17)
= 4.647.
