Three of the sides will require fencing and the fourth wall already exists. If the farmer has 116 feet of fencing, what are the
dolphi86 [110]

Answer:

29 ft x 58 ft

Step-by-step explanation:

Let x be the length of each side perpendicular to the wall, and y be the length of the side parallel to the wall.

The amount of wire available is:

116 = 2x+y\\y=116-2x

The area of the region is:

A=xy=x(116-2x)\\A(x)=116x-2x^2

The value of 'x' for which the derivate of the area function is zero will yield the maximum area:

A(x)=116x-2x^2\\A'(x) = 116-4x=0\\x=29\ ft

The value of y is:

y=116-2*29\\y=58\ ft

The dimensions of the region with the largest area are 29 ft x 58 ft.

If x varies inversely as p and x=2 when p=4 find the formula connecting them​
Doss [256]

Answer:

x = \frac{p}{2}

Step-by-step explanation:

x ∝ p

x = kp -------(1)

<em><u>Where k is the constant of proportionality.</u></em>

Now, x = 2 when p = 4

<em>Putting in the above formula</em>

2 = k(4)

<em>Dividing both sides by 4</em>

k = \frac{2}{4}

=> k = \frac{1}{2}

Putting k in (1)

x = \frac{p}{2}

<em>Now this is the required equation connecting both.</em>
