The cube root is a number multiplied by itself three times to get another number
The code to use is y = x**(1/3)
<h3>How to determine the code to use</h3>Assume the variable is x, and the cube root of x is y.
So, we have the following equation
In Python, the code to use is y = x**(1/3)
Hence, the code that Rachelle can use in her calculation is x**(1/3)

<em><u>Answer</u></em>
5 hours
<em><u>Explanation</u></em>
The two working together can finish a job in
Also, working alone, one machine would take one hour longer than the other to complete the same job.
Let the slower machine working alone take x hours. Then the faster machine takes x-1 hours to complete the same task working alone.
Their combined rate in terms of x is
This should be equal to 20/9 hours.
Multiply through by;
Factor to get:
It is not feasible for the slower machine to complete the work alone in 4/9 hours if the two will finish in 20/9 hours.
Therefore the slower finish in 5 hours.
Note: The matrix referred to in the question is:
Answer:
a) [5/18, 5/18, 4/9]'
Explanation:
The adjacency matrix is
To start the power iteration, let us start with an initial non zero approximation,
To get the rank vector for the first Iteration:
Multiplying the above matrix by 1/3
