The easiest thing to find in a table showing a linear relationship is the slope. If the x is increasing by one each and every time (or cell because we are talking about tables), then the difference between each y value is the slope. Also, if you are lucky enough to have that sort of table, you can easily find the y-intercept by looking at the y value that is next to the x value of 0. Otherwise, work backward to find the y-intercept. For every x value you go down to try and get to 0, minus the y values also by the slope.
Answer:
9/pi or 2.865
2.25/pi or 0.716
9/25pi or 0.115
36/pi or 11.459
Step-by-step explanation:
The formula for the volume of a cone
V= 1/3pir^2h
V= volume
pi= 3.141592...
r= radius
h= height
1) 3= 1/3pi (1)^2h
9=pi(h)
h= 9/pi or 2.865
2) 3= 1/3pi (2)^2h
9=4pih
h= 9/4pi or 0.716
3) 3= 1/3pi (5)^2h
9= 25pih
h= 9/25pi or 0.115
4) 3=1/3pi (1/2)^2h
9= 1/4pih
h= 36/pi or 11/459
The answer should be -3xy^2 (4x^2y^3 + 3x - 4y)
