Answer:
Side of square bottom=6.46 m
Height of box=4.31 m
Step-by-step explanation:
Let s be the side bottom
Height of box=h
Volume of box=
Volume of box=


Cost of bottom=$40 per square m
Cost of sides =$30 per square m
Total cost=


Differentiate w.r.t s






Again,differentiate w.r.t s

Substitute s=6.46

Hence, the cost is minimum at s=6.46

Side of square bottom=6.46 m
Height of box=4.31 m
160 grams of zinc. 760/ 19 is equal to 40 so then we’d want to multiple 4 x 40 because that’s how much were growing by so then zinc is 160 grams
I'm not 100% sure if I am right, but for number 9 you would pick two points on , let's just say you pick points (0, 1) and (2, -2). Then you would find those points in the table. So in this case the answer would be D. And I'm not really sure how to explain #10 but you basically work out each problem with the graph to see if it makes sense. For example if you try working out problem F it wouldn't make sense since you start of with 10 dollars and earn 2 each day. But on the graph it shows that you are loosing two. Sorry if I didn't explain it right, if you have more questions let me know!
