Answer:
The value of x is 40.
Step-by-step explanation:
The measures of the angles in a quadrilateral are represented by x, 2x, 3x, and 3x.
According to the angle sum property of quadrilateral, the sum of interior angles of a quadrilateral is always 360 degree.
Since the measures of the angles in a quadrilateral are represented by x, 2x, 3x, and 3x, therefore
This is the equation which is used to solve for the value of x.
Therefore the value of x is 40.
Let . The gradient of
at the point (1, 0, 0) is the normal vector to the surface, which is also orthogonal to the tangent plane at this point.
So the tangent plane has equation
Compute the gradient:
Evaluate the gradient at the given point:
Then the equation of the tangent plane is
Answer:
Step-by-step explanation:
I can't give you a direct answer, but i know something that might help
It's easy to show that is strictly increasing on
. This means
and
Then the integral is bounded by
