um a is the blue and d is the one that is going up and down and bis the one that goes side to side

Step-by-step explanation:

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.

Answer:

x = [tex]\frac{-212}{3}[/tex]

y = 24

Step-by-step explanation:

-3x - 8y = 20  .... (1)

-5x + y = 19   .... (2)

What we can do is take the (2) equation

-5x + y = 19

and solve for y by adding 5x to both sides

y = 24

now that we have y we substitute it in for y in equation (1)

-3x - 8(24) = 20

-3x - 192 = 20

we want to solve for x so we need to get its self.

add 192 to both sides

-3x = 212

now we divide both sides by -3. It's going to be a fraction.

x = [tex]\frac{-212}{3}[/tex]

Answer:

x=-4

y=-1

Step-by-step explanation:

-3x-8y=20

-5x+y=19

rewrite for y:

y=19+5x

substitute y

-3x-8(19+5x)=20

-3x-152-40x=20

-3x-152-40x+152=20+152

-43x=172

-43x/-43=172/-43

x=-4

substitute x

-5(-4)+y=19

20+y=19

y=-1

check:

-3(-4)-8(-1)=20

12+8=20

-5(-4)+-1=19

20-1=19

when both l and m are parallel then

(4x+7) = (6x-63)

-2x = -70

-x = -70/2

-x = -35

x = 35

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

Answer:

D

Step-by-step explanation:

Step-by-step explanation:

sides opposite to equal angles are equal in length :

angle45 = angle 45

r = s

by Pythagoras theorem :

r² + s² = (9√2 )²

s²+s²= 9 × 9 × 2

2s²= 9× 9×2

s²= 9 × 9

s= √9× 9

s = 9

r= s = 9 units .
