the answer is 2x2+12z-5 (its also in the picture)
Take partial derivatives and set them equal to 0:

We find one critical point within the boundary of the disk at

. The Hessian matrix for this function is

which is positive definite, and incidentally independent of

and

, so

attains a minimum

.
Meanwhile, we can parameterize the boundary by

with

, which gives

with critical points at

At these points, we get


so we attain a maximum only when

, which translates to

.
Answer:
View graph
Step-by-step explanation:
The closest by default to 1100 cubic inches is taking two side and two front covers and that would give you 1080.12 cubic inches since two of the covers you must subtract 3 cm per side and side which would add 6 cm in total so outside would be 35 cm and indoor 29 cm
. According the graph
29*50*3= 4350 * 2 lid = 8700 cm3
30*50*3= 4500*2 lid = 9000 cm3
So 8700+9000 = 17700 cm3 to inches 3 = 1080.12 cm3
Answer:
47.25 mph
Step-by-step explanation:
Represent the total distance traveled as 2x. Average speed= total distance/total time
When going at 42 mph, the time would be x/42 and when going at 54 mph the time would be x/54 to travel x distance. Add x/42 and x/54 together to get 16x/378. Then divide 2x by 16x/378 to get 47.25 mph. Also this is RSM innit?
Answer:
Step-by-step explanation:
12.80+3.42= 16.22
16.22-9.70= 6.52 that's your answer
