The volume of a packing box is 5 – x cubic feet. The width of the box is x feet and the length is x – 2 feet. The height is give
Zina [12379]
According to the definition, the volume is indicated by
V = h * w * l
where
V: Volume
h: height
w: width
l: length
By solving for height, we get:
h = V / (w * l)
h = (5 - x) / ((x) * (x - 2))
The expression is undefined for x values that cause the denominator to equal zero:
((x) * (x - 2)) = 0
x = 0
x = 2
Answer
h = (5 - x) / ((x) * (x - 2))
x = 0
x = 2

Rachel found this rate of change for the scenario represented in the table.
babunello [11817]
THE FUNCTION IS CONTINUOUS - True
The table indicates that for every hour indicated, there is a corresponding amount of juice (cups) provided. The graph would represent a linear progression between the hours of 4 and 8 without any discontinuities.

TIME IS THE DEPENDENT VARIABLE - False
Time acts as the independent variable since it remains unaffected by any other factors. Conversely, the number of cups is contingent upon the hours, categorizing it as a dependent variable.

THE SCENARIO IS CHARACTERIZED BY
A LINEAR FUNCTION AS THE RATE OF CHANGE IS CONSTANT - True
The rate of change is a steady 53 cups per hour, indicating a linear function.

AS TIME INCREASES, THERE ARE FEWER CUPS OF JUICE POURED EACH HOUR - False
Since the rate of change is positive, the cups poured each hour will actually increase.

FOR EACH EXTRA HOUR, 53 CUPS OF JUICE ARE POURED - True
The hourly difference in cups poured is consistently 53.

There are cars and motorcycles in a campus parking lot. The parking attendant noticed there are a total of 294 tires and a total
babunello [11817]
Esto no puede ser correcto ya que si hay 60 coches, eso implica 240 ruedas de coches, y 25 bicicletas significan 50 ruedas de bicicletas, lo que suma un total de 290 ruedas. Si hubiera 1 coche adicional, habría 86 vehículos y 294 ruedas, o si se agregaran 2 bicicletas más, eso resultaría en 87 vehículos y 294 ruedas.
