In term we have to +1 and in number there’s a pattern = 1,2,3, 1,2,3, 1,2,3, 1,2,3....and so on
Hope it helps u understand ask if u have any doubts
Answer: 30
Step-by-step explanation:
If we were to draw diagonal BD, then we would create two congruent triangles, and we could find the area of each using the formula
.
However, since there are two triangles, we can double this, giving us
.
So, the area is 
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:
option D
Step-by-step explanation:
Take the two through which the lines passes.
Let it be ( -5 , 0) and ( 0 , -3)
Step 1 : Find slope, m


Step 2 : Find the equation

I could be wrong but 20.5 and 7.5
