Answer to Problem 4E
The quantities
Explanation of Solution
Given:
z is proportional to the product of x and y and z is 10 when x is 4 and y is 5.
Definition:
If the quantities
For some constant
Calculation:
It is given that z is proportional to the product of x and y.
Compare the above equation with the definition of proportionality in equation(1).
Substitute 10 for z, 4 for x and 5 for y in equation (2).
Simplify the above equation to find the value of k.
Substitute the value of k in equation (2)
Therefore, the quantities
