Answer:
Required equation of tangent plane is 
.
Step-by-step explanation:
Given surface function is,
To find tangent plane at the point (5,-1,1).
We know equation of tangent plane at the point $(x_0,y_0,z_0)[/tex] is,
So that,
Substitute all these values in (1) we get,
Which is the required euation of tangent plane.
Answer:
57
Step-by-step explanation:
180-123=57
that line the angle is on is a straight line and a straight line is 180 degrees
ABCDEFGH = 22.
HEFG = 12
ABCD = 10
10^6 = 1,000,000
10^2 = 100
1,000,000 / 100 = 10,000
so 8.76x10^6 is 10,000 times greater than
The triangle must be isosceles, due to the perpendicular bisector. Therefore, the expression 20 - 15 can be used to yield an answer of B. 5.
Hope this helps!
