Aloiza [94]

<h3>Answer: Choice C</h3>

Explanation:

This is after using the nCr combination formula

$_n C _r = \frac{n!}{r!*(n-r)!}$

where in this case n = 7 and r = 4. Note how n-r = 7-4 = 3.

We use nCr instead of nPr because the order of the toppings doesn't matter.

How do I solve this?Farmer Ed has 1500 meters of fencing, and wants to enclose a rectangular plot that borders on a river. If fa

Dafna1 [17]

We need to find the maximum (Vertex of the function)

Let:

L = Length = 1500 - 2x

W = Width = x

The area is given by:

$\begin{gathered} A=W\cdot L \\ A=x(1500-2x) \\ A=1500x-2x^2 \\ A(x)=1500x-2x^2 \end{gathered}$

We can find the maximum using the following formula:

$\begin{gathered} xm=-\frac{b}{2a} \\ where \\ a=-2 \\ b=1500 \\ so\colon \\ xm=-\frac{(1500)}{2(-2)}=\frac{1500}{4}=375 \end{gathered}$

Evaluate the area for the value we found previously:

$A(375)=-2(375)^2+1500(375)=-281250+562500=281250$

The largest area that can be enclosed is 281250m²
