John leaves his home. He travels 5 blocks south and three blocks west. As the crow flies, how far is John from his home?

Answers

Answer:

5.83 blocks away from his home

Step-by-step explanation:

If he travels 5 blocks south and 3 blocks west, the distance from his house considered along with the distances travelled gives a right angled triangle whose opposite side and adjacent sides are the distances travelled north and west.

The distance from his house after moving 3 blocks west is the hypotenuse side. As such, the distance may be computed using Pythagoras' theorem. Let the distance from his house be G

G^2 = 5^2 + 3^2

G^2 = 25 + 9

= 34

G = √34

=5.83

John is 5.83 blocks away from his home

A farmer wants to construct a rectangular pigpen so only 3 sides of the pen will need to be fenced. If the farmer has 400 ft of fence, whats the maximum area he can enclose?

Answers

The dimensions of the rectangular pigpen with the largest possible area are 50 ft×25 ft.

The area and perimeter of a rectangle in the study of differential calculus, specifically in optimization problems are functions of two variables that depending on what is requested in these problems can be objective functions or link functions between the variables.

We use what we know about the perimeter of the rectangle to find a condition equation that expresses the length a in terms of the width b.

P(a, b)=a+2b [Perimeter of the fence of the rectangular pigpen]

p(a, b)=2a+3b [Substitute P(a, b)=100]

100=a+2b

a=100-2b

We must find the largest area. Using the condition equation, find the area as a function of the variable b.

A(a, b)=ab [total area of the rectangular pigpen]

A(a, b)=(100-2b)b [Replace a=100-2b]

A(a, b) = 100b-2b²

Objective function Domain

A(a, b) = 100b-2b²

D={b∈R : b>0} [Domain of the objective function]

To find the extremes of the function we have to look for the critical points of the function and apply the second derivative test.

A(a, b) = 100b-2b²

A'(a, b) =100-4b [First derivative of the objective function]

A'(b)=0

100-4b=0

4b=100

b=25 [Critical point]

Applying sufficient condition for extremes

A'(b)=100-4b [First derivative of the objective function]

A''(b)=-4 [Second derivative of the objective function]

A''(b)=-4 [A''(b)<0∀b∈D]

b=25 [Maximum point of the objective function]

Calculate the dimension of the rectangular pigpen

b=25 [Width of the rectangular pigpen]

a=100-2(25)=50 [Length of the rectangular pigpen]

Therefore, the dimensions of the rectangular pigpen with the largest possible area are 50 ft×25 ft.
