A farmer is constructing a rectangular pen with one additional fence across its width. Find the maximum area that can be enclose

konstantin123 [22]

The maximum area of the pen is the highest area the pen can have

The maximum area is 16200 square yards

Let the dimension be x and y.

So, the perimeter is given as:

$\mathbf{P = 360}$

Because it has one additional fence, the perimeter is calculated as:

$\mathbf{2x + y = 360}$

Make y the subject

$\mathbf{y = 360 - 2x}$

The area is calculated as:

$\mathbf{A = xy}$

Substitute $\mathbf{y = 360 - 2x}$

$\mathbf{A = x(360 -2x)}$

Expand

$\mathbf{A = 360x -2x^2}$

Differentiate

$\mathbf{A' = 360 -4x}$

Set to 0

$\mathbf{360 -4x = 0}$

Rewrite as:

$\mathbf{4x = 360}$

Divide both sides by 4

$\mathbf{x = 90}$

Substitute 90 for x in $\mathbf{A = 360x -2x^2}$

$\mathbf{A = 360 \times 90 - 2 \times 90^2}$

$\mathbf{A = 16200}$

Hence, the maximum area is 16200 square yards

Will mark brainlest if correct! pls help

Answer:

See below.

Step-by-step explanation:

$y_2 = 4x^2$

$x = 1$

$y_2 = 4(1)^2 = 4 = a$

a = 4

$y_3 = 4^x$

$x = 1$

$y_3 = 4^1 = 4 = b$

b = 4

$y_1 = 4x$

$x = 2$

$y_1 = 4(2) = 8 = c$

c = 8

$y_3 = 4^x$

$x = 2$

$y_3 = 4^2 = 16 = d$

d = 16

$y_1 = 4x$

$x = 3$

$y_1 = 4(3) = 12 = e$

e = 12

$y_2 = 4x^2$

$x = 3$

$y_2 = 4(3)^2 = 36 = f$

f = 36

$y_3 = 4^x$

$x = 3$

$y_3 = 4^3 = 64 = g$

g = 64

What are the zeros of the function (x) = x2 – 3x+2?

sashaice [31]

Step-by-step explanation:

f(x) = x² - 3x + 2 = (x - 2)(x - 1).

When f(x) = 0, (x - 2)(x - 1) = 0.

=> x = 2 or x = 1.
