X < 10
Step-by-step explanation:
Answer:
The dots next to the seven are another way to write multiplication. So, 7 times 7 times 7 times 7 is another way of seven 7 to the fourth power, which equals 2401
So, here we have an exponential function.
Remember that an exponential function has the form:
Where a represents an initial amount, and r is the rate of this amount to change. (Increase, or decrease).
So, given that the population of City A in 2000 was 40 thousand people and the population increased by 13% each year, we can say that
So,
For city B:
But something different happens with city C. This is not an exponential function, this is a linear function.
So,
Answer:A= 13^2= 169
