No, this would not make a triangle because there is a rule that any two sides of a triangle of added together must be larger than the one that is left over.

(csc x - 1) (csc x + 1)

<h2>Explanation:</h2>

Here we have the following expression:

$(csc x - 1) (csc x + 1)$

So we need to extend this. Remember that the difference of squares tells us:

$(a-b)(a+b)=a^2-b^2$

So here:

$a=cscx \\ \\ b=1$

Thus:

$(csc x - 1) (csc x + 1)=csc^2x-1 \\ \\ \\ But: \\ \\ cscx=\frac{1}{sinx} \\ \\ \\ Then: \\ \\ csc^2x-1=\frac{1}{sin^2x}-1=\frac{1-sin^2x}{sin^2x}=\frac{cos^2x}{sin^2x}=cot^2x \\ \\ \\ Finally: \\ \\ \boxed{(csc x - 1) (csc x + 1)=cot^2x}$

Subtract 6x from both sides, then square root, and have parabola.

MAXImum [283]

Answer:

She uses $\frac{1}{12}$ of the sheet of paper to make the flower.

Step-by-step explanation:

She cuts 1/2 of a piece of paper.

Of what was cut, she used 1/6 to make a piece.

What fraction of the sheet of paper does she use to make the flower?

A sixth of one half. So

$\frac{1}{6}*\frac{1}{2} = \frac{1}{12}$

She uses $\frac{1}{12}$ of the sheet of paper to make the flower.

Answer:

42 cm ^2

Step-by-step explanation:

The area of a triangle is 1/2 B x H ( one half base times height)

The base is 6 cm and the height is 14 cm. So the full equation now is

1/2 (6) (14)

First you multiple 6 times 14 which is 84. Next you just divide it by 2 because 1/2 is half of the number. 84 divided by 2 is 42. So your answer is

42 cm ^2 (centimetres squared)
