Quadrilateral QRST has two pairs of congruentes sides, but it is not a parallelogram. What figure is it? What further condition

Whitepunk [10]

Answer:

The correct answer is: [C]:

________________________________________________

" {The figure is a kite. To be a parallelogram, it would have to have pairs of <em>opposite</em> congruent sides, not just congruent sides. } ."

________________________________________________

Step-by-step explanation:

________________________________________________

Note that "all" squares are "parallelograms" ; and that "all" rectangles are

"parallelograms" ;

yet: "Not All parallelograms" are "squares" or "rectangles".

________________________________________________

The question asks:

________________________________________________

"Quadrilateral QRST has two pairs of congruent sides, but it is not a parallelogram.

What figure is it?

What further condition would have to satisfy to be a parallelogram? " .

________________________________________________

So; we can rule out:

________________________________________________

"Answer choices:

[A]: "The figure is a square..." ;

________________________________________________

[B]: "The figure is a rectangle..." ; <em><u>AND</u></em> :

________________________________________________

[D]: "The figure is a square..." .

________________________________________________

We are left with:

________________________________________________

Answer choice: [C]:

________________________________________________

" { The figure is a kite. To be a parallelogram, it would have to have pairs of <em>opposite</em> congruent sides, not just congruent sides. } " .

The period of this function is <br><br><br><br> π / 4<br><br> 8<br><br> 2π<br><br> π / 2

Serhud [2]

ANSWER

$\frac{\pi}{2}$

EXPLANATION

The period refers to the interval over which the function completes one full cycle.

The given function completed four cycles in on the the interval.

[-π,π]

The period is

$= \frac{\pi - - \pi}{4}$

$= \frac{\pi + \pi}{4}$

Simplify;

$= \frac{2 \pi}{4}$

$= \frac{\pi}{2}$

The last choice is correct.

The height of each soup can is 4.138 centimeters, if the the volume of soup to be 325 cubic centimeters per can and the area of the base of each can is 25 square centimeters.

Step-by-step explanation:

The given is,

The volume of soup to be 325 cubic centimeters per can.

The area of the base of each can is 25 square centimeters.

Step: 1

Formula to calculate the volume of cylidrical soup can,

$Volume, V = Bh$ ............................(1)

Where, B - Base area of cylidrical soup can

h - Height of cylindrical soup can

Step: 2

From the given values,

Base area, B = 25 square centimeters

Volume, V = 325 cubic centimeters

Equation (1) becomes,

325 = ( 25 ) (h)

h = $\frac{325}{25}$

= 13 centimeters

Height of cylindrical soup can, h = 13 centimeters

Result:

The height of each soup can is 4.138 centimeters, if the the volume of soup to be 325 cubic centimeters per can and the area of the base of each can is 25 square centimeters.
