Answer:
Sum of the Roots = 37
Product of the Roots = 27
Step-by-step explanation:
Here, the given expression is
Now the general Quadratic Equation is of the form:
Here, Sum of the Roots =
and the Product of the Roots =
So, comparing the general equation with the given equation, we get:
a = 1, b = -37 and c = 27
So, Sum of the Roots = = 37
and the Product of the Roots = = 27
Let . The tangent plane to at (1, 2, -6) has equation
We have
Then the tangent plane has equation
Let , and . The tangent plane to at a point is
We have
so that this plane has equation
In order for this plane to be parallel to the previous plane, we need to have
so the point we're looking for is (2, 6, -36).
68% will be 1 standrd deviation either side of the mean so a reasonable estimate will be (25*0.68) / 2 = 8.5
