Justin wants to use 188ft of fencing to,fence off the greatest possible retangular area for a garden .What dimensions should he

marshall27 [118]

The greatest area that can be enclosed by a given amount of material will always be a square...

M=2L+2W so we can say:

2L=M-2W

L=(M-2W)/2

area is:

A=LW and using L from above:

A=W(M-2W)/2

A=(MW-2W^2)/2

dA/dW=(M-4W)/2

d2A/dW2=-4

Since acceleration, d2A/dW2, is a negative constant, when velocity, dA/dW=0, it is at an absolute maximum for A(W).

dA/dW=0 only when M-4W=0, 4W=M, W=M/4

from earlier we found L=(M-2W)/2 and using W from above we get:

L=(M-M/2)/2

L=(2M-M)/4

L=M/4

So L=W=M/4, thus it is a square.

That's the proof, anyway...

188=2x+2y

94=x+y

y=94-x

A=xy and using y from above:

A=94x-x^2

dA/dx=94-2x, d2A/dx2=-2, as explained earlier, since acceleration is a negative constant, when dA/dx=0, it is at an absolute maximum for A(x).

dA/dx=0 only when 94-2x=0, 2x=94, x=47

and from earlier, y=94-x, so y=94-47

y=47

So the dimensions that produce the greatest area are:

47ft by 47ft

And thus the greatest area is:

47^2=2209 ft^2

the hypotenuse of a right triangle is 6 1 /2cm and its area is 7 1/2sq.cm. Calculate the length of its perpendicular sides.

Romashka-Z-Leto [24]

Answer:

The Length of the triangle = 2.307 cm

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given hypotenuse of a right triangle is = 6 1 /2 cm

Let assume the height of the triangle h = $\frac{13}{2} c m$

Given Area of the triangle = 7 1/2 sq.cm.

A = $\frac{15}{2} sq .c m$

<u><em>Step(ii):</em></u>-

We know that Formula

<em>Area of the triangle </em>

$A = \frac{1}{2} base X height$

$\frac{15}{2} = \frac{1}{2}X b X \frac{13}{2}$

On calculation , we get

Base of the triangle (b) = $\frac{30}{13} = 2.307 c.m$

<u>Conclusion</u>:-

The length of the triangle = 2.307 c.m

Find and label -0 on the number line. Explain.<br><br> Does -0 just mean 0?

poizon [28]

The opposite of the number 0 that is -0 on the number line will be equal to 0 itself.

A number line may be defined as a scale consisting of numbers labelled from 0 to 9 which are used to plot or mark different points for various entities. Number line extends from 0 to 9 in the positive side that is usually taken as right-hand side and it extends from 0 to -9 in the negative side that is usually taken as the left-hand side. The numbers on the right-hand side of number line have their opposites on the left-hand side. The opposite of a number x is taken as -x. For example, the opposite of 4 is taken as -4 and 4 lies on right-hand side whereas -4 lies on left-hand side. 0 lies on the center of number line and is taken as the main point. It is neither positive nor negative so the opposite of 0 is 0. The figure of number line is attached.
