I would like to create a rectangular orchid garden that abuts my house so that the house itself forms the northern boundary. The

son4ous [18]

Answer:

x = 15 ft

y = 15 ft

A(max) = 225 ft²

Step-by-step explanation:

Let call "x " and " y " sides of the rectangle x (side paralll to the northern boundary, then:

A(r) = x*y and 4*x + 2*2*y = 120 or 4*x + 4*y = 120

4*x + 4*y = 120 ⇒ x + y = 30 ⇒ y = 30 - x

Area of the garden as a function of x is:

A(x) = x* ( 30 - x ) ⇒ A(x) = 30*x - x²

Taking derivatives on both sides of the equation

A´(x) = 30 - 2*x

A´(x) = 0 ⇒ 30 - 2*x = 0

2*x = 30

x = 30/2

x = 15 ft

And y = ( 30 - x )

y = 15 ft

A(max) = 15*15

A(max) = 225 ft²

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

<u>Step 1: Define</u>

Point (2, 5)

Point (-3, 7)

<u>Step 2: Identify</u>

x₁ = 2, y₁ = 5

x₂ = -3, y₂ = 7

<u>Step 3: Find slope </u><em><u>m</u></em>

Simply plug in the 2 coordinates into the slope formula to find slope<em> m</em>

Substitute in points [Slope Formula]: $\displaystyle m=\frac{7-5}{-3-2}$
[Slope] [Fraction] Subtract: $\displaystyle m=\frac{2}{-5}$
[Slope] [Fraction] Rewrite: $\displaystyle m=\frac{-2}{5}$
