To find out whether or not the equation x^2 - 4x + y^2 = -3 intersects the x-axis, we must set y = 0 in the equation (because at every point on the x-axis, y = 0).
x^2 - 4x + 0 = -3
We then want to solve for x. We can do this by factoring.
x^2 - 4x + 3 = 0
By factoring...
(x - 3)(x - 1)
We can set each of these equations = 0 to solve where the function crosses the x-axis.
x - 3 = 0
x = 3
x - 1 = 0
x = 1
So we know at x = 1 and x = 3, the function x^2 - 4x + y^2 = -3 intersects the x-axis.
Answer:
Step-by-step explanation:
The volume of the cylinder is = base * height
base=Pi*radius*radius, where
base=3.1416*2*2 , height=5
Volume=3.1416*2*2*5
Volume =62.8 cubic units.
