Answer:
2-7i is the correct option.
Step-by-step explanation:
We have been given the complex number real part 2 and imaginary part 7 it can be expressed as:
2+7i
And the conjugate means in the complex number is opposite sign of imaginary part that is in general:
a+ib will have conjugate a-ib
So, the conjugate of 2+7i is 2-7i
Hence, Option d is correct.

<h3>Exponential functions </h3>
The standard exponential equation is expressed as;
y = ab^x
where
- a is the intercept
- b is the initial population
- x is the time
Given the following parameters
Substittute the given parameters into the formula
y = 2000(1.02)^x
If x = 20 (from 2000 to 2020)
The population will be expressed as;
y = 2000(1.02)^20
y = 2972 populations
Hence the population will be about 2972 population in 2020
