I'm pretty sure that they are there to show symmetry
Answer:
12 m
sorry if its wrong i did my best
The height of the container be so as to minimize cost will be 1.20. inches.
<h3>How to calculate the height?</h3>
The volume of the box will be:
= 2x × 3x × h
= 6x²h
Volume = 6x²h
12 = 6x²h
h = 2x²
The cost function will be:
C = 2.60(2)(6x²) + 4.30(12x)h
C = 31.2x² + 51.6xh
Taking the derivative
62.4x + 51.6h
h = 1.20
Therefore, the height of the container be so as to minimize cost will be 1.20 inches.

I'll do number 11 for you
Area of a sector can be found using
A = (πr²)C/360 where C is the measure of your central angle

A ≈ 23.56 m²
Oh, I guess rounded to the nearest tenth is 23.6
Yes because it fits the rule of 5 cars a day so 5 cars for 5 days is 25 and 5 cars for 12 days is 5*12= 60
