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.
The 2 smallest lengths in a triangle have to add up to be greater that the longest side of the triangle. In this case, the longest side is 20. The 2 smallest sides are 5 and 10. 5+10=15, but 15<20. This is why these 3 lengths can’t create a triangle.
Answer:
81π ft³
Step-by-step explanation:
If the diameter is 6 ft, the radius is 3 ft.
The volume is V = (area of base)(height).
Here, V = (π[3 ft]²)(9 ft) = 81π ft³
Volume = 45
