Answer:
I think 144.44 is the answer
The dimensions of the square base after cutting the corners will be (40-2x). The depth of the box will be x, so its volume is given by
V = x(40-2x)²
You can differentiate this to get
V' = 12x² -320x -1600
Setting this to zero and factoring gives
(3x-20)(x-20) = 0
The appropriate choice of solutions is
x = 20/3 = 6 2/3
The
dimensions of the box of maximum volume are
26 2/3 in square by 6 2/3 in deepThe
maximum volume is
(80/3 in)²(20/3 in) =
4740 20/27 in³
Answer:
The answer is C
Sn=3(1-1/2^n)
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
1. multiply 5 and 12 to get 60
2. multiply 5 and m to get 5m
3. the equation would be 60 + 5m = 100
4. next, subtract 60 on both sides
5. your equation so far is 5m = 40
6. then divide 5 on both sides
7. then you have your answer m = 8
