Note, in the 1st row given '9x', in the 2d one - '9(0)', then it means the substitution '0' instead of 'x'. In other words <u>x=0</u> !
answer: x-intercept is '0', y-intercept is '12'
4x^2/2x^2
Bth x^2 will cross each other
And only this will be left
2
Answer:
Step-by-step explanation:
Let's use the integral formula for the surface area of revolution of the function y(x) around the x-axis, which is:
and which in our case, we can obtain the following:
Recall as well that , which gives us the limits of integration:
If we compare it with the geometry formula:
Lateral surface of cone =
which is exactly the expression we calculated with the integral.
The answer should be negative 12. Take the 2 and square it then multiply by -3.
