How Can Cassie probe the quadrilateral ABCD is a parallelogram

Mathematics
1 answer:
Mashcka [7]3 years ago
7 0

Answer:

Explained below.

Step-by-step explanation:

A quadrilateral with two opposite pair of sides parallel to each other is known as a parallelogram.

To prove that a quadrilateral is a parallelogram, the following properties can be used:

  • The two pair of opposite sides are same in length, i.e. AB = CD and AD = BC.
  • The two pair of opposite angles are congruent, i.e. ∠A ≅ ∠C and ∠B ≅ ∠D.
  • The two pair of consecutive angles are supplementary, i.e. ∠A + ∠B = 180° and ∠B + ∠D = 180°.
  • The diagonals of the quadrilateral bisect each other. i.e. AE = EC and BE = ED.

If the quadrilateral ABCD satisfies these properties then it can be proved that the quadrilateral ABCD is a parallelogram.

A piece of cardboard is 13 inches by 26 inches. A square is to be cut from each corner and the sides folded up to make an open-t
Vanyuwa [196]

Answer:

Hence the maximum possible volume will be the 778.53 c.c

Step-by-step explanation:

Given:

A rectangle with 13 x 26 dimensions

And corners are cut to form side squares.

To Find:

Maximum possible volume for box

Solution :

Consider a rectangle of 13 x 26 dimension with and side of square  at corner be x.

(Refer the attachment)

Now,

Formulating the volume equation for the box

So corner square sides we are going to fold up which makes height of the box

and remaining part will be length and breadth

As shown in fig,

Length=26-x

breadth=13-x

And height will be x

V(x)=x*(26-x)*(13-x)

To get maximum volume differentiate the above equation,

V(x)=x*(26*13-26*x-13*x+x^2)

V(x)=x^3-39x^2+338x\\

V'(x)=3x^2-78x+338

V''(x)=6x-78

Now ,Solve the Quadratic Equation to get x values,

3x^2-78x+338=0

x=[-b±(b^2-4ac)^1/2]/2a

x=[78±Sqrt[(78)^2-4*338*3)]/2*3

x=[78±Sqrt(3028)]/6

x=[78±55.027]/6

x=78+55.027/6 or x=78-55.027/6

x=22.17  or x=3.8288

Use these values in 6x-78 to know which value posses the max and min value for the function.

So when x=22.17

6x-78=6*22.17-78

=55.02>0  i.e function will have minimum value .

When x=3.8288

6*3.8288-78

=-55.0272<0 i.e. Function will have maximum value

Now, the function will defines the maximum volume

V(x)=x^3-39x^2+338x

V(x)=3.8288^3-39*(3.82883)^2+338*3.8288

V(x)=56.13-571.73+1294.13

V(x)=778.53 C.C
