Answer:
d⁴y/dx⁴ = -12/x⁴
Step-by-step explanation:
y = 2In x
We want to find d⁴y/dx⁴. This is the fourth derivative.
Using product rule, first derivative is;
dy/dx = 2/x
Well,
For example
2.34 * 10^6 will be....
2,340,000
It is because if you have the positive powers, you move your decimal to the right. In this case the power is 6 so you move your decimal to the right 6 times.
Here's another example
1.23 X 10^-2
The answer will be 0.0123 because you move your decimal two the left two times. The power is negative 2 so you move it to the left.
Final tips: If you have positive power, move it to the right and if you have negative power, move it to the left.
Based on the streams of income that Li Wei has, we can calculate that he has a total passive income of <u>$3,010.</u>
Passive income refers to income that is made without a person actively involving themselves in the activity generating the income.
In this scenario, the passive income sources are:
- Stock dividends
- Business investment interest
- Royalties from a novel
Total passive income therefore is:
= 530 + 1,080 + 1,400
= $3,010
In conclusion, the total passive income is $3,010.
