box with a square base and open top must have a volume of 4,000 cm3. Find the dimensions of the box (in cm) that minimize the am
Naya [18.7K]

Answer:

Hence the width, length is 20 cm and height is 10 cm

Step-by-step explanation:

Since the box has a square base, let length = width = x. Also, let the height = y, therefore:

The volume of box = width * length * height

4000 = x * x * y

4000 = x²y

y=4000/x²

The surface area (SA) = area of the base + sum of the area of each side

SA = x² + xy + xy + xy + xy

SA = x² + 4xy

substitute y = 4000/x²

SA = x² + 4x(4000/x²)

SA = x² + 16000/x

Taking the derivative:

SA' = 2x - 16000/x²

making SA' = 0:

0 = 2x - 16000/x²

2x = 16000/x²

2x³ = 16000

x³ = 8000

x = 20 cm

y = 4000 / x² = 4000 / 20² = 10 cm

Hence the width, length is 20 cm and height is 10 cm

The time spent dancing (minutes) and the amount of calories burned can be modeled by the equation c = 5.5t. Which table of value
pishuonlain [190]
To build the table you just have to give values to t and then calculate the corresponding c a per the model.


If the model is c = 5.5 t this is the table

t          c
           5.5 t

0         5.5(0) = 0

1         5.5(1) = 5.5

2          5.5(2) = 11.0

3         5.5(3) = 16.5

4          5.5(4) = 22.0

5          5.5(5) = 27.5


The viables solutions are all where t is equal or greater than 0. You can even use decimal values for t. You cannot use negative values for t.
