x^2 - x/5 + 2 = 0
Subtract 2 from both sides.
x^2 - x/5 = -2
Multiply all terms by 5.
5x^2 - x = -10
Add 10 to both sides.
5x^2 - x + 10 = 0
We can now apply the quadratic formula:
1 ± (√ 1 - 200) / 10
1 ± √-199 / 10
1 ± i√199 / 10
<h3><u>The solutions are equal to 1 + or - i times the square root of 199 divided by 10.</u></h3>Answer:
The volume of the solid is:
Step-by-step explanation:
See the graph of the region attached.
To find the intersection between the line and the parabola we set the equation equal to each other, and solve that quadratic equation by factorization:
Since the region is the one for then the intersection we are interested on is x=1 as it can also be seen in the graph.
Then we set the integral using shell method for revolving about the y-axis:
Where h(x) is the height of the shell which here is the distance between the parabola and the line, so (since the line is on the top we subtract from it the parabola)
Then the integral becomes:
Notice the limits of the integral are the x-axis (x=0) and the intersection of the parabola and the line that we found before (x=1)
Now, solving the integral:
Start by factoring the and distributing the x:
Then use the basic rule to integrate:
Then evaluate the antiderivative in the limits and subtract:
So the volume of the solid is
