If

represent a family of surfaces for different values of the constant

. The gradient of the function

defined as

is a vector normal to the surface

.
Given <span>the paraboloid

.
We can rewrite it as a scalar value function f as follows:

The normal to the </span><span>paraboloid at any point is given by:

Also, the normal to the given plane

is given by:

Equating the two normal vectors, we have:
</span>

Since, -1 = 2 is not possible, therefore
there exist no such point <span>
on the paraboloid
such that the tangent plane is parallel to the plane 3x + 2y + 7z = 2</span>
.
D__ is 7.5<x
C is x<10
Step-by-step explanation:
just do the inequality and graph
Answer:
finding x:
XYZ = 117
6x+44-10x+65=117
-4x = 8
x=-2
finding the measure of the angles:
XYW=
6*-2 + 44 = 32
WYZ=
-10*-2+65 = 85
Answer:
no
Step-by-step explanation:
because 0<1,
so 0.80...<0.81
