Answer:

All trapezoids are quadrilaterals.

Step-by-step explanation:

Incorrect. Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A trapezoid can never be a parallelogram. The correct answer is that all trapezoids are quadrilaterals.

How to calculate the distance for graphs?

ollegr [7]

Answer:

$\sqrt{(x1-x2)^{2}+(y1-y2)^{2} }$

Step-by-step explanation:

This is the distance formula for cartesian coordinate systems, or your typical xy graph. If given two points to find the distance between, you can assign '1' or '2' to the points, i.e. (1,1) and (2,2) could be: (1,1) is (x1,y1) and (2,2) is (x2,y2). It doesn't matter which point is 1 or 2. If we were to use those example points in this formula, we would have:

$\sqrt{(1-2)^{2}+(1-2)^{2}}$

We can simplify and come up with:

$\sqrt{(-1)^{2}+(-1)^{2}}$

= $\sqrt{2}$

We must remember that square roots can be positive OR negative, HOWEVER, because you are looking for a distance it must be positive $\sqrt{2}$ .

Hope this helped!

HELP!!! Simplify cos^2 0 -1/ 4sin^2 0?

Shkiper50 [21]

We need to simpify the given expression. The given expression to us is ,

<u>Given </u><u>Expression</u><u> </u><u>:</u><u>-</u><u> </u>

$\sf\implies \dfrac{ cos^2\theta -1}{4 \ sin^2\theta }$

<u>Using </u><u>Identity</u><u> </u><u>:</u><u>-</u><u> </u>

$\sf\implies \red{ sin^2\theta + cos^2\theta = 1}$

<u>So </u><u>that</u><u> </u><u>:</u><u>-</u><u> </u>

$\sf\implies - sin^2\theta = cos^2\theta -1$

<u>We </u><u>have</u><u> </u><u>:</u><u>-</u><u> </u>

$\sf\implies \dfrac{ cos^2\theta -1}{4 \ sin^2\theta } \\\\\sf\implies\dfrac{ - sin^2\theta}{4sin^2\theta}=\boxed{\sf -\dfrac{1}{4}}$

<u>Hence </u><u>the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>-</u><u>1</u><u>/</u><u>4</u><u>. </u>
