There is 1500 ft of fencing available to make 6 identical pens. Find the maximum area for EACH pen (meaning maximum of one pen).

hjlf

Answer:

The maximum area is therefore is 93750 ft²

Step-by-step explanation:

The given parameter are;

The a]length of fencing available = 1500 ft.

The perimeter of the figure = 9·x + 4·y

Therefore, 9·x + 4·y = 1500 ft.

The area of the figure = 6 × (x × y) = 3·x × 2·y

From the equation for the perimeter, we have;

9·x + 4·y = 1500

y = 1500/4 - 9/4·x = 375 - 9/4·x

y = 375 - 9/4·x

Substituting the value of y in the equation for the area gives;

Area = 3·x × 2·y = 3·x × 2·(375 - 9/4·x) = 2250·x - 27/2·x²

Area = 2250·x - 27/2·x²

The maximum area is found by taking the derivative and equating to zero as follows;

d(2250·x - 27/2·x²)/dx = 0

2250 - 27·x = 0

x = 2250/27 = 250/3

x = 250/3

y = 375 - 9/4·x = 375 - 9/4×250/3 = 187.5

The maximum area is therefore, 3·x × 2·y = 3 × 250/3 × 2 × 187.5 = 93750 ft²

The maximum area is therefore = 93750 ft.²

An engineer is surveying a building with a device that is 5 feet above the ground. He is 50 feet from the building and is lookin

dolphi86 [110]

1. Check the sketch of the problem.

2. In right triangle DCE,

$tan50= \frac{EC}{DC}= \frac{x}{50}$

tan 50 can be found to be 1.19 using a scientific calculator or other software.

$1.19=\frac{x}{50}$

x=1.19*50=59.5 (feet)

3. The height of the building is 59.5+5=64.5 (feet)

Answer: 64.5 (feet)

Common factors of 24 and 32

Afina-wow [57]

Answer:

So the GCF of 24 and 32 is 8 .

Any common factor of 24 and 32 will be a factor of the GCF 8 .

Hence the positive common factors of 24 and 32 are:

1,2,4,8

Step-by-step explanation:

Divide the larger number by the smaller to give a quotient and remainder.

If the remainder is 0

then the smaller number is the GCF.

Otherwise repeat with the smaller number and the remainder.
