Elena’s backyard is in the shape of a rectangle. She created a triangular-shaped flower bed (shown as the shaded region) to plant flowers in.

Answer:

The area of the triangular flower bed is <u>125</u> square feet. The area of her backyard that does not include the flower bed is <u>575</u> square feet.

Step-by-step explanation:

AreaOfTriangle

\left[\begin{array}{ccc}A =\frac{H_{b} B}{2}\end{array}\right]

\left[\begin{array}{ccc}A =\frac{H_{b} B}{2} = \frac{10*25}{2}\end{array}\right]

\left[\begin{array}{ccc}\frac{10*25}{2}=125 \end{array}\right]

AreaOfSquare

\left[\begin{array}{ccc}A=LW\end{array}\right]

\left[\begin{array}{ccc}A=LW=35*20\end{array}\right]

\left[\begin{array}{ccc}35*20\\=700\end{array}\right]

\left[\begin{array}{ccc}700-125\\=575\end{array}\right]

The height is 15 feet.

0.5xbxh<_120 (equate formula for area of triangle to 120)

0.5x16xh<_120

16xh<_240 (120 divided by 0.5)

h<_15 (240 divided by 16)

An open box is to be made out of a 12-inch by 20-inch piece of cardboard by cutting out squares of equal size from the four corn
Natali5045456 [20]

Answer:

Length = 15.14, width = 7.14 and height = 2.43  inches.

( correct to the nearest hundredth).

Step-by-step explanation:

Let the lengths of the squares cut out be x inches.

Then the width of the box will be 12 - 2x and the length will be

20 - 2x inches.

The height of the box is x inches.

Volume V = x(20-2x)(12-2x)

To find the value of x when V is a maximum we find the derivative and equate it to zero.

V = x( 240 - 64x + 4x^2)

V = 4x^3 - 64x^2 + 240x

dV/dx = 12x^2 - 128x + 240 = 0

4(3x^2 - 32x + 60) = 0

This won't factor so we use the formula:

x = [-(-32) +/- √((-32)^2 - 4*3*60)] / 6

= 8.24, 2.43.

So one of these gives a maximum Volume.

The second derivative

d^2V/dx^2 = 24x - 128

When x = 8.24,  this = 69.6 (positive) so this gives a minimum.

x = 2.43 gives a negative  value ( -49.7)  so this is the maximum

So the dimensions are:-

length = 20 - 2(2.43) = 15.14

width = 12 - 2(2.43) = 7.14

height = 2.43.
