Answer: 208a = 256
Step-by-step explanation:
product means multiplication so
208a = 256
Answer:
Here it is!!
Step-by-step explanation:
It is the same as you will encounter the same things as u would while adding integers. Negative plus negative would equal negative. etc. It would be different because you need to take the numbers on the right side of the decimal into account. Basically, -2.66 + -2.66 = -5.32
Answer:
a
Step-by-step explanation:
Answer: -28
Step-by-step explanation:
4-32= -28
The critical points of <em>h(x,y)</em> occur wherever its partial derivatives
and
vanish simultaneously. We have

Substitute <em>y</em> in the second equation and solve for <em>x</em>, then for <em>y</em> :

This is to say there are two critical points,

To classify these critical points, we carry out the second partial derivative test. <em>h(x,y)</em> has Hessian

whose determinant is
. Now,
• if the Hessian determinant is negative at a given critical point, then you have a saddle point
• if both the determinant and
are positive at the point, then it's a local minimum
• if the determinant is positive and
is negative, then it's a local maximum
• otherwise the test fails
We have

while

So, we end up with
