A fence is to be built to enclose a rectangular area of 260 square feet. The fence along three sides is to be made of material t
Nat2105 [25]

Answer:

Length of the rectangle = 9.58 feet and width = 27.14 foot

Step-by-step explanation:

Let the length of the rectangular area is = x feet

and the width of the area = y feet

Area of the rectangle = xy square feet

Or xy = 260

y = \frac{260}{x} -------(1)

Cost to fence the three sides = $3 per foot

Therefore cost to fence one length and two width of the rectangular area

= 3(x + 2y)

Similarly cost to fence the fourth side = $14 per foot

So, the cost of the remaining length = 14x

Total cost to fence = 3(x + 2y) + 14x

Cost (C) = 3(x + 2y) + 14x

C = 3x + 6y + 14x

  = 17x + 6y

From equation (1)

C = 17x+\frac{260\times 6}{x}

Now we take the derivative,

C' = 17 - \frac{1560}{x^{2} }

To minimize the cost of fencing,

C' = 0

17 - \frac{1560}{x^{2} } = 0

\frac{1560}{x^{2} } = 17

x^{2} =\frac{1560}{17}

x=\sqrt{\frac{1560}{17} }

x = 9.58 foot

and y = \frac{260}{9.58}

y = 27.14 foot

On of Tho Mcd<br> 8. Write the standard form of the equation y + 4 = - 12 (x – 1).
LiRa [457]

Answer:

12x + y = 16

Step-by-step explanation:

Standard Form: Ax + By = C

Step 1: Write point-slope form

y + 4 = -12(x - 1)

Step 2: Find slope-intercept form

y + 4 = -12x + 12

y = -12x + 16

Step 3: Find standard form

12x + y = 16

Slope is negative for each...Remember Y-int and rise/run for slope.
Y=mx+b 

Y= -2/3X - 2

Y= -5/2x + 2
