The slope formula is m= y2-y1/x2-x1.
m= 4-0/2-5
m=4/-3
Therefore, 4/-3 is the slope.
With these types of probe lens with no coefficient for x, all you have to do is find two number that multiply to be 12, and those same two numbers must add to be 7.
Answer: (x+3)(x+4) because 3 and 4 multiply to be 12 as well as add to be 7.
The equation for volume is V= (pi)(R^2)xH
For Pi use 3.14
So switch the variables for the numbers that we know
V= (3.14)(3^2)x4
3^2= 9
3.14 x 9= 28.26
28.26x9 = 113.04
113.04 to the nearest tenth would be 113.
