Answer:

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem we have

Substitute the values and solve for k


therefore
the equation of the line is equal to

The volume of a sphere is found with the following formula:

The radius is raised to a power of 3. Since the radius is 2 <em>meters</em>, this means that the volume would be measured in
cubic meters.
It is 5:9 in simplest form
They mean the decimal portion. it goes 10s. 100s. 1,000s. so the 100ths is thr number 9
