Population can be expressed as P = 22000(0.972)^t, when t = time since 2010.
So, in 2040, t = 30.
P(30) = 22000(0.972)^(30)
P = 9384.49
Round down to 9384 people= that is the expected population in 2040.
hope this helps :)
Answer: Second option.
Step-by-step explanation:
The area of a rectangle can be calculated with the following formula:
![A=lw](https://tex.z-dn.net/?f=A%3Dlw)
Where "l" is the length and "w" is the width.
You can notice in the figure that there are two equal purple rectangles, two equal green rectangles and two equal pink rectangles.
Knowing that each square of the grid has a side lenght of 1 centimeter:
1. The area of one purple rectangle is:
![A_{pp}=8\ cm*4\ cm=32\ cm^2](https://tex.z-dn.net/?f=A_%7Bpp%7D%3D8%5C%20cm%2A4%5C%20cm%3D32%5C%20cm%5E2)
2. The area of one green rectangle is:
![A_{gr}=8\ cm*2\ cm=16\ cm^2](https://tex.z-dn.net/?f=A_%7Bgr%7D%3D8%5C%20cm%2A2%5C%20cm%3D16%5C%20cm%5E2)
3. The area of one pink rectangle is:
![A_{pk}=4\ cm*2\ cm=8\ cm^2](https://tex.z-dn.net/?f=A_%7Bpk%7D%3D4%5C%20cm%2A2%5C%20cm%3D8%5C%20cm%5E2)
Therefore, in order to find the surface area of the rectangular prism, you can multiply each area calculated before by 2 and then you must add the products.
Then, you get that this is:
![SA=2(32\ cm^2)+2(16\ cm^2)+2(8\ cm^2)\\\\SA=112\ cm^2](https://tex.z-dn.net/?f=SA%3D2%2832%5C%20cm%5E2%29%2B2%2816%5C%20cm%5E2%29%2B2%288%5C%20cm%5E2%29%5C%5C%5C%5CSA%3D112%5C%20cm%5E2)
This is just the answer digitally i cant explain the process
W=2x because of the z pattern
2x+90+3x-5=180
5x=95
X=19
Answer:
U were 20% off
Ure estimate was 80%
Step-by-step explanation:
16/20 is 80%
100%-80% is 20%
