Answer:

Similarity:

In Both cosine and sine graphs, a positive and negative number vertically flips the graph and tells whether the graph starts at maximum (positive) or minimum (negative).

Difference:

The difference between the sine and the cosine graph is the point where they start.

The graph of positive cosine starts at the maximum while that of the negative cosine starts at the minimum.

The graph of a positive sine starts at the middle, goes up and then down while that of the negative sine starts at the middle goes down and then up.

Answer:

C. 14xy - 6y²

Step-by-step explanation:

The distributive property will essentially result in the sum of the product of the "outside term" with each of the "inside terms".

Here, the "outside term" is 2y and the "inside terms" are 7x and -3y. So:

2y(7x - 3y) = 2y * 7x + 2y * (-3y) = 14xy - 6y²

The answer is C.

$\huge\sf\underline{\purple{❥}\pink{Q}\orange{U}\blue{E}\red{S}\green{T}\purple{I}\pink{O}\red{N}}$

rationalize the denominator of 1/√3

$\huge\sf\underline{\purple{❥}\pink{A}\orange {N}\blue{S}\red{W}\green{E}\purple{R}}$

$\frac{1}{ \sqrt{3} } \\ \\(to \: rationalize \: the \: denominator \\ we \: have \: multiply \: \frac{1}{ \sqrt{3} } \: to \: the \:given \: fraction \: \: \: ) \\ = \frac{1}{ \sqrt{3} } \times \frac{1}{ \sqrt{3} } \\ = ( \frac{1}{ \sqrt{3} } ) {}^{2} \\ = \frac{1}{3}$

How does doubling the lengths of the sides of a rectangle to form a similar rectangle affect the area

MrRissso [65]

Doubling the lengths of the sides of a rectangle quadruple the area

<h3>How to determine the effect?</h3>

Let the dimension of the rectangle be L and W.

So, the area is

A = LW

When the lengths are doubled, we have:

A2 = 2L * 2W

This gives

A2 = 4LW

This means that the initial area is multiplied by 4

Hence, doubling the lengths of the sides of a rectangle quadruple the area
