The back of George's property is a creek. George would like to enclose a rectangular area, using the creek as one side and fenci
Setler79 [48]

Answer:

The maximum possible area of the pasture = 2450 square feet

Step-by-step explanation:

Let the length of the creek be 'L'

and, the width of the rectangular area be 'B'

Data provided:

The rectangular area is enclosed using the creek as one side and fencing for the other three sides

Thus, 2B + L = 140 feet      

or

L = 140 - 2B              .........(1)

Now,

Area of the rectangular land, A = L × B

using (1)

A = ( 140 - 2B) × B

or

A = 140B - 2B²

Now to maximize the area, differentiating the area with respect to width 'B'

we have

\frac{\textup{dA}}{\textup{dB}}  = 140 - 2 × 2 × B ...........(2)

for point of maxima or minima , \frac{\textup{dA}}{\textup{dB}}  = 0

thus,

140 - 2 × 2 × B = 0

or

4B = 140

or

B = 35 feet

differentiating  (2) with respect to B, for verifying the maxima or minima

\frac{d^2\textup{A}}{\textup{dB}^2}  = 0 - 2 × 2 = -4

since, \frac{d^2\textup{A}}{\textup{dB}^2} is negative,

therefore,

B = 35 feet is point of maxima

from (1)

L = 140 - 2B

or

L = 140 - 2 × 35

or

L = 140 - 70 = 70 feet

Hence,

The maximum possible area of the pasture = L × B

= 70 × 35

= 2450 square feet

A red candle is 8 inches tall and burns at a rate of 710 inch per hour. a blue candle is 6 inches tall and burns at a rate of 15
Katarina [22]
Red candle:
Initial height  = 8 in
Burn rate = 710 in/h
After x hours, the height will be
h₁ = 8 - 710x

Blue candle:
Initial height = 6 in
Burn rate = 15 in/h
After x hours, the height will be
h₂ = 6 - 15x

When the two heights are equal, then
h₁ = h₂
8 - 710x = 6 - 15x
-695x = -2
x = 0.00288 hours

Answer:
The answer may take one of these forms:
0.003 hours, or
0.0029 hours, or
0.00288 hours.

Find the ratio of 4 meter to 50 centimetre
ladessa [460]

                          (4 meters)  /  (50 centimeters)

                  =      (4 x 100 centimeters)  /  (50 centimeters)

                  =      (400 centimeters)  /  (50 centimeters)

                  =              (400) / (50)

                  =                     8       .
