Answer:

\large\boxed{\sf \ \ \ 1757 \ km^2 \ \ \  }

Step-by-step explanation:

Hello,

<em>I would recommend that you checked the answers I have already provided as this is the same method for all these questions, and maybe try to solve this one before you check the solution.</em>

<u>At the beginning the area is 2100</u>

<u>After one year</u> the area will be

   2100*(1-3.5%)=2100*0.965

<u>After n years</u> the area will be

   2100\cdot0.965^n

So after 5 years the area will be

   2100\cdot0.965^5=1757.34027...

So rounded to the nearest square kilometer is 1757

Hope this helps

Answer: 1757 km²

Step-by-step explanation:

Because 3.5% = 0.035, first do 1-.035 to get .965.  Then do 2100*.965*.965*.965*.965*.965 to get 1757.34027.

In which quadrant does an angle of 1300° terminate? Assume the vertex of the angle is at the origin and one leg of the angle is
NikAS [45]
<h3>Answer: quadrant 3</h3>

Work Shown:

Divide 1300 over 360

1300/360 = 3.611 approximately

Focus on the whole part 3. There are 3 full revolutions

3*360 = 1080, which subtracts off to get 1300-1080 = 220 left over.

The remainder 220 tells us where the angle points. It's in quadrant 3 since 220 degrees is between 180 degrees and 270 degrees.

This math promblem!!!!
fiasKO [112]
1. You convert all the numbers into decimals.
   a. For 8 1/9 you multiply 8x9 and add the numerator which in this case is one, so the equation would be 8x9=72     then 72+1= 73
   b. For 81/10 I used a calculator for accuracy and I just divided 81 by 10 because the fraction line can also be used as a division sign. For this I got 8.1
2. Now I looked at all the numbers I had including the fractions I converted to decimals... 8.115, 8.55, 73, and 8.1
3. Lastly, I put the numbers in order from least to greatest: 8.1, 8.115, 8.55, and 73
4. In order to figure out which one is the smallest and largest, I just added zeros on the end of the numbers so they would all be the same: 8.1-->8.100, 8.115 I kept the same because it already had 3 decimal places, 8.55--> 8.550, and 73--> 73.000
5. Then i could tell which number was the largest by the decimal place numbers.
**Hope this was helpful... It's kind of hard to explain online but hopefully you have a better understanding of how to do it!**

Gabriel buys a car for $5,160. His state charges 7% sales tax, $87 for license plates, and $30 for safety and emissions fees. Ho
postnew [5]

Answer:You have 30 days from the date of purchase to title and pay sales tax on your newly purchased vehicle. If you do not title the vehicle within 30 days, there is a title penalty of $25 on the 31st day after purchase. The penalty increases another $25 for every 30 days you are late with a maximum penalty of $200.

When you purchase your vehicle, you may obtain a temporary permit, transfer license plates from a vehicle you already own, or you may purchase new license plates. Our online sales tax calculator may help you estimate the taxes and fees you will pay.

True or false : The function shown has an absolute Minimum
MakcuM [25]

Answer:

Cannot be determined

Step-by-step explanation:

You cannot assume the function travels down infinitely, because the function is not given to you. The graph could go up down left or right for all you know, you just cannot see it.
