63
The sector is
; there are 360 degrees in a circle.
You use the formula
.
18cm is the radius, and then you square it to get 324.
Multiply 324 by
You get 63
Answer:
22°
Step-by-step explanation:
abd is a 90° angle so to find cbd you just have to do 90 minus 68 and you'll find 22°
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
Answer:
The slope of line A is C. 2
Step-by-step explanation:
You can check the slope by dividing the rise (how many units up) and the run (how many units across). This line has a rise of rise of 4 and a run of 2. Diving 4 by 2 gives you a slope of 2.
