has critical points where the partial derivatives simultaneously vanish:
So we have three critical points to consider,
,
, and
.
The function has Hessian
At the critical points, we have
which means there is a minimum at (0, 0) of
;
which means
is a saddle point; and
which means
is also a saddle point.
Answer;
The correct equation;
= 1.01 R
Explanation;.
The formula for resistance (R) = resistivity (r) x Length (L)/Area (A)
As there is an increase in length, there is also an increase in the resistance.
If we increase the length by 1 % of its original value, assuming the area remains constant, then the resistance will also becomes 1% = 1/100 = 0.01 times of its original value as resistance is directly proportional to the length.
Therefore; the new resistance = R + 1/100R
= R + R/100
= 101R/100
The new resistance = 1.01 R
2/3 + 2/3 = 4/6 Hope this helps!
The area of the irregular shape is 100
M is the slope, so, y=mx or y=2x. If y is 8 then x is 4.
y=6 x=r
6÷2=3, so r=3.
hope this helps and sorry if it got confusing.
