Answer:
what is the equation and what do we solve for?
Step-by-step explanation:
what we solve for?
Answer:
9 (i - 1)
Step-by-step explanation:
Simplify the following:
-7 + 3 i - (-6 i + 2)
-(2 - 6 i) = -2 + 6 i:
6 i - 2 - 7 + 3 i
-2 + 6 i - 7 + 3 i = (6 i + 3 i) + (-2 - 7) = -9 + 9 i:
9 i - 9
Factor 9 out of 9 i - 9 giving 9 (i - 1):
Answer: 9 (i - 1)
Answer:

Step-by-step explanation:
Given that the left angle = 
The right angle across from it 
The other two angles are x and x.
We know that the sum of angles at a point equals 360 degrees.
Therefore,

The value of x is approximately 38.5 degrees.
Using an exponential function, it is found that:
- For Country A, the doubling time is of 43 years.
- For Country B, the growth rate is of 1.9% per year.
<h3>What is the exponential function for population growth?</h3>
The exponential function for population growth is given as follows:

In which:
- P(t) is the population after t years.
- P(0) is the initial population.
- k is the exponential growth rate, as a decimal.
For Country A, we have that k = 0.016. The doubling time is t for which P(t) = 2P(0), hence:






t = 43 years.
For Country B, P(36) = 2P(0), hence we have to solve for k to find the growth rate.






k = 0.019.
For Country B, the growth rate is of 1.9% per year.
