Answer:

Step-by-step explanation:
Let
Side of square base=x
Height of rectangular box=y
Area of square base=Area of top=
Area of one side face=
Cost of bottom=$9 per square ft
Cost of top=$5 square ft
Cost of sides=$4 per square ft
Total cost=$204
Volume of rectangular box=
Total cost=



Substitute the values of y

Differentiate w.r.t x







It takes positive because side length cannot be negative.
Again differentiate w.r. t x

Substitute the value

Hence, the volume of box is maximum at x=2.2 ft
Substitute the value of x

Greatest volume of box=
Answer:
slope = 4
Step-by-step explanation:
We can find the slope of a line when knowing 2 points by using the slope formula,
.
and
represent the x and y values of the first point, respectively.
and
represent the x and y values of the second point, respectively.
The two points we have are (2,8) and (0,0). So, in this case,
= 2,
= 8,
= 0, and
= 0. Let's substitute those values into the formula and solve to get the slope:



So, the slope is 4.
