Answer:
[tex]p= kd^{2}u^{3}[/tex]
Step-by-step explanation:
Using k as the constant of proportionality.
The expression that expresses the relationship : p varies jointly with the square of d and the cube of u.
Varies jointly means that p will change as 'd' and 'u' will change together with respect to their powers.
We get the expression as:
[tex]p= kd^{2}u^{3}[/tex]
The equation of p is [tex]p\ =\ kd^2u^3[/tex]
Variation can be direct, inverse or joint.
From the question, we understand that:
p varies jointly with the square of d and the cube of u
This is represented as:
[tex]p\ \alpha\ d^2u^3[/tex]
Express as an equation
[tex]p\ =\ kd^2u^3[/tex]
Where k represents the constant of proportionality.
Hence, the equation of p is [tex]p\ =\ kd^2u^3[/tex]
