For the functions given below, write the optimality conditions and find the stationary points. use your calculator (or matlab) when needed to do some of the computations, but show all the work. also determine the local minimum, local maximum, and inflection points for the function (inflection points are those stationary points that are neither minimum nor maximum).
f (x1, x2) = x12 + 4x1x2 + x2^2 + 3

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

i think the amount would be $140.62
