How do i write out this problem
a is jointly proportional with the square of x and the square root of y and
a = 25 when x = 5 and y = 9
Answer provided by our tutors
If a varies jointly with respect to square of x and square root of y, the equation will be of the form:
where k is a constant.
Since a = 25 when x = 5 and y = 9 we have:
If you want to find the constant k you need to solved the above equation.
