Given:
The table of values is:
x : -7 -5 -3 -1
y : 5 9 13 17
To find:
Whether the given data is linear and then find the equation.
Solution:
The given data is linear if the slope and rate of change is constant.
Slope formula:
Using the slope formula. we get
Since the rate of change is constant, i.e., 2, therefore the given data is linear.
The slope of a linear equation is 2 and it passes through the point (-7,5). So, the equation of the line is:
Adding 5 on both sides, we get
Therefore, the equation for the given data is .
The volume of a cone is (1/3) that of its similar cylinder.
Thus the volume of the cone B would be:
Thus the volume of the cone B would be:
