Answer:
15 Kg cm²
Step-by-step explanation:
Given that V varies inversely with P then the equation relating them is
V = ← k is the constant of variation
To find k use the condition
V = 360, P = 20, then
360 = ( multiply both sides by 20 )
k = 7200
V = ← equation of variation
When V = 480, then
480 = ( multiply both sides by P )
480P = 7200 ( divide both sides by 480 )
P = 15

Step-by-step explanation:
See attachment for graph
Required
a. Determine the slope
b. Find the x intercept and explain what it represents
a. The slope
To calculate the slope, we start by selecting any two corresponding values of x and y from the graph.
Next, we calculate the slope (m)
b. The x intercept
This is the point where
From the graph.
