Answer:
1/3
Step-by-step explanation:
(8/15) - (1/5)
change 1/5 to 3/15 (which is equivalent to 1/5)
(8/15) - (3/15) = (5/15)
Simplify
(5/15) = (1/3)
Answer: f(-6) = 10.
Step-by-step explanation: This above equation is the only one that contains both coordinates of one of the ordered pairs in the correct order, so it is the answer.
Answer:
The anwser is 213.465 m2
Step-by-step explanation:
Yes uh get it i guess
The optimum shape of such a box is half a cube. The corresponding cube will have a volume of 2×256 ft³ = 512 ft³ = (8 ft)³. Such a box has a square base that is 8 ft on a side. If the height is half that of the cube, it will be 4 ft.
The dimensions of your box will be 8 ft square by 4 ft high.
_____
If the base dimension is x ft, the area (quantity of material) is
... a = x² + 4x(256/x²)
... a = x² + 1024x⁻¹
Then the derivative of area with respect to x is
... a' = 2x -1024x⁻²
Setting this derivative to zero and solving for x gives the value of x for minimum area.
... 0 = 2x -1024/x²
... 512 = x³
... x = 8 . . . . . . . . same as above.
The answer is
x=9
Work: 6/54=9
