I wrote this for math class, does it make sense?A very famous equation, Euler’s identity relates the seemingly random values of

pi, e, and the square root of -1. It is considered by many to be the most beautiful equation in mathematics.
A more general formula is

e^{i x} = \cos x + i \sin x

When x = \pi , the value of \cos x is -1, while i\sin x is 0, resulting in Euler’s identity, as -1 + 1 = 0.

Also please don't hate I am only in sixth grade...

Which set of values could be the side lengths of a 30-60-90 triangle?
PilotLPTM [1.2K]

The correct answer is option B which is the set of values that could be the side lengths of a 30-60-90 triangle are (6,6√3, 12).

<h3>What is the right-angled triangle?</h3>

A triangle has three angles of 30-60 and 90 degrees in which the two sides are perpendicular to each other.

The three sides of the triangle will be calculated by applying the Pythagorean theorem:-

The sum of the square sides will be equal to the square of the third side.

For sides  (6,6√3, 12)

12² = 6² + (6√3)²

144 = 36 + (36 x 3)

144 = 36 + 108

144 = 144

Therefore the correct answer is option B which is the set of values that could be the side lengths of a 30-60-90 triangle (6,6√3, 12).

Describe the end behavior of a ninth-degree polynomial with a negative leading coefficient
Degger [83]

Given:

The degree of polynomial = 9

Leading coefficient is negative.

To find:

The end behavior of the polynomial.

Solution:

Let the polynomial be P(x).

We have,

Degree of polynomial = 9, which is odd.

Leading coefficient is negative.

If the degree of a polynomial is odd and leading coefficient is negative, then

P(x)\to \infty\text{ as }x\to -\infty

P(x)\to -\infty\text{ as }x\to \infty

Therefore, the end behavior of the given polynomial is P(x)\to \infty\text{ as }x\to -\infty,P(x)\to -\infty\text{ as }x\to \infty.
