Answer:
Step-by-step explanation:
Rate = 10%
Time = 2 years
Initial CO2 = 280000 metric ton
1st year
10% × 280000
= 28000 metric ton.
2nd year
10% × (280000 - 28000)
= 25200 metric ton.
Metric ton of CO2 produced at the end of the 2nd year = 252000 - 25200
= 226800 metric ton of CO2.
The answer is 85 miles/hour. Hope it helps! If you could vote me brainiest, that would be awesome, thanks!

Option A is correct.
Step-by-step explanation:
![A=\left[\begin{array}{ccc}-4&-1&-9\\-9&6&9\\-1&-1&3\end{array}\right] \\B=\left[\begin{array}{ccc}-10&-7&-5\\9&-7&-1\\9&-4&2\end{array}\right]](https://tex.z-dn.net/?f=A%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-4%26-1%26-9%5C%5C-9%266%269%5C%5C-1%26-1%263%5Cend%7Barray%7D%5Cright%5D%20%5C%5CB%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-10%26-7%26-5%5C%5C9%26-7%26-1%5C%5C9%26-4%262%5Cend%7Barray%7D%5Cright%5D)
We need to find 6A - 8B
Multiply matrix A with 6 and matrix B with 8 and then subtract 6A - 8B

So,
Option A is correct.
Yes that is true. What is the question?
Answer:
x = -6
Step-by-step explanation:
3/ x = 4/(x-2)
Using cross products
3 (x-2) = 4x
Distribute
3x - 6 = 4x
Subtract 3x from each side
3x-3x-6 = 4x-3x
-6 =x
