Answer: y=36 degrees
Step-by-step explanation: the exterior angle of a triangle is equal to the sum of the two remote interior angles of a triangle. using this, you can subtract 98 from 134 degrees to find your answer. 134-98 is 36 degrees. Hope this helps :)
Answer
20
Step-by-step explanation:
well if you find a common denominator it would be 20 because 4 and 5 both go into 20 so
Just do (41x25)+(6x110
which is 1091
Answer:
C) The partial derivatives were not evaluated a the point.
D) The answer is not a linear function.
The correct equation for the tangent plane is
or 
Step-by-step explanation:
The equation of the tangent plane to a surface given by the function
in a given point
can be obtained using:
(1)
where
and
are the partial derivatives of
with respect to
and
respectively and evaluated at the point
.
Therefore we need to find two missing inputs in our problem in order to use equation (1). The
coordinate and the partial derivatives
and
. For
just evaluating in the given function we obtain
and the partial derivatives are:


Now, substituting in (1)

Notice that until this point, we obtain the same equation as the student, however, we have not evaluated the partial derivatives and therefore this is not the equation of the plane and this is not a linear function because it contains the terms (
and
)
For finding the right equation of the tangent plane, let's substitute the values of the partial derivatives evaluated at the given point:

or
