A college is planning to construct a rectangular parking lot on land bordered on one side by a highway. The plan is to use 440 f

NARA [144]

Let x represent side opposite to highway and y represent other two opposite sides as shown in the diagram.

The perimeter of the parking lot will be sum of 3 sides that is $x+y+y=x+2y$ .

We have been given that the plan is to use 440 feet of fencing to fence off the other three sides. This means that perimeter of 3 sides is 440.

$x+2y=440$

$x=440-2y$

We know that area of rectangle is length times width, so area of parking lot will be $A=x\cdot y$

Upon substituting value of x, we will get:

$A(y)=(440-2y)\cdot y$

$A(y)=440y-2y^2$

Now we will find the derivative of area function as:

$A'(y)=\frac{d}{dy}(440y)-\frac{d}{dy}(2y^2)$

$A'(y)=440-4y$

Let us find critical point by equating derivative to 0.

$440-4y=0$

$440=4y$

$\frac{440}{4}=\frac{4y}{4}$

$110=y$

Now we will substitute this value is equation $x=440-2y$ to solve for x as:

$x=440-2(110)$

$x=440-220=220$

Therefore, the dimensions of 220 feet by 110 feet will enclose the maximum area.

Jude Enjoys Eating Potato Chips. He likes to place 3 chips together in a stack to make interesting flavours. If he only has one

frez [133]

Using the combination formula, it is found that he can make 4 different stacks.

The order in which the balls are selected is not important, as stated in the problem. hence the <em>combination formula</em> is used to solve this question. If the order was important, then the permutation formula would be used.

<h3>What is the combination formula?</h3>

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem, he has four flavors, and will choose three of them for the stacks, hence the number of different stacks is given as follows:

$C_{4,3} = \frac{4!}{3!1!} = 4$

He can make 4 different stacks.
