A town is planning a playground. It wants to fence in a rectangular space using an existing wall. What is the greatest area it c

777dan777 [17]

Answer:

1250 $ft^{2}$

Step-by-step explanation:

We are given that the playground is fenced on three sides of the playground and the four side has an existing wall.

Let the length of the rectangle be 'X' feet and width be 'Y' feet.

As the fencing is done using 100 feet of fence. We get the relation between the sides and the fence as, X + 2Y = 100.

As, X + 2Y = 100 → X = 100 - 2Y

Now, the area of the rectangle = XY = X × ( 100 - 2Y ).

i.e Area of the rectangle = $-2Y^{2} +100Y$ .

The general form of a quadratic equation is $y=ax^{2}+bx+c$ .

The maximum value of a quadratic equation is given by $x=\frac{-b}{2a}$ .

Therefore, the greatest value of $-2Y^{2} +100Y$ is at Y = $\frac{-100}{2 \times -2}$ = $\frac{-100}{-4}$ = 25.

Thus, Y = 25 and X = 100 - 2Y → X = 100 - 2 × 25 → X = 50.

Hence, the area of the rectangle is XY = 50 × 25 = 1250 $ft^{2}$ .

A lake near the Arctic Circle is covered by a 222-meter-thick sheet of ice during the cold winter months. When spring arrives, t

Here we must see which information about the graph of a linear relationship is given. The information given is just the y-intercept and a point that is not an intercept, thus the correct option is E.

<h3>Linear relationships:</h3>

So we define a general linear relationship as:

y = a*x + b

Where a is the slope and b is the y-intercept.

In this problem we know that:

Originally, the sheet of ice is 2 meters thick.
The thickness decays at a constant rate
After 3 weeks, the thickness is 1.25 meters.

The first point gives us the y-intercept (the thickness at week 0), the second one gives us the fact that the relationship is linear, and the third one is just a point on the line (that can be used to get the slope.)

So the information given is just the y-intercept and a point that is not an intercept, thus the correct option is E.
