Your correct answer should be F
Answer:
- Decay rate, r = 0.014
- Initial Amount =120,000
- P(10)=104,220
Step-by-step explanation:
The exponential function for growth/decay is given as:
In this problem:
The city's initial population is 120,000 and it decreases by 1.4% per year.
- Since the population decreases, it is a Decay Problem.
- Decay rate, r=1.4% =0.014
- Initial Amount =120,000
Therefore, the function is:
When t=10 years
The answer is B) 1/3.
There are 6 faces on a rectangular prism, each of which is a rectangle.
The area of the front and back is given by 25(8) = 200 sq. cm.
The area of the bottom and top is given by 25(4) = 100 sq. cm.
The area of the right and left is given by 4(8) = 32.
There are 2 faces out of 6 with an area that is not a multiple of 100; 2/6 = 1/3.
Answer: 30%
Percentage Increase = (Final amount - Initial amount) / Initial amount x 100
=30%
