Converting 200 miles to the amount of carbon dioxide emission that would be 1.884 tons annually. This will be the amount of carbon dioxide given that 200 miles is monthly covered.

Answer:

Carbon dioxide emitted in the atmosphere is 129.6 kg.

Step-by-step explanation:

As we know when we burn 1 gallon of gasoline produces 20 pounds of carbon dioxide.

Since in i gallon a truck covers 14 miles which means in 14 miles a truck produces 20 pounds of carbon dioxide gas.

Now we can calculate the amount of CO2 emitted by a truck in 200 miles.

∵ During 14 miles CO2 emitted = 20 pounds

∴ during 1 mile CO2 emitted will be = 20/14 pounds

∴ While covering 200 miles CO2 emitted = (200×20)/14 = 285.71 pounds of CO2.

Or by converting 281.71 pounds to kg amount of CO2 will be = 129.6 kg

Which of the following is a solution of z^5 = 1 + √3 i?
nordsb [41]

Answer:

Option 2 is right

Step-by-step explanation:

Given that

z^5=1+\sqrt{3} i

We can write this in polar form with modulus and radius

|z^5|= \sqrt{1+3} =2\\tan of Angle t =\sqrt{3} \\

Hence angle = 60 degrees and

|z^5|= 2(cos60+isin60)

Since we have got 5 roots for z, we can write 60, 420, 780, etc. with periods of 360

Using Demoivre theorem we get 5th root would be

5th root of 2 multiplied by 1/5 th of 60, 420, 780,....

z= \sqrt[5]{2} (cos12+isin12)\\z=\sqrt[5]{2} (cos84+isin84)\\\\z=\sqrt[5]{2} (cos156+isin156)\\\\z=\sqrt[5]{2} (cos228+isin228)\\\\z=\sqrt[5]{2} (cos300+isin300)\\

Out of these only 2nd option suits our answer

Hence answer is Option 2.

3 (x-5) =5<br> what is x?
azamat

Answer: 20/3

So when solving this equation first distribute our 3,we will now have   3x-15=5.

Next we will Add 15 to both sides of our equation. Now we have 3x=20.Then divide our terms,and you will have 3x/3 = 20/3

<u>This will leave you with  1x=20/3. </u>

So the X is 20/3.

      Hope that helped!
