Answer:

Yes , it is possible (see the explanation)

Step-by-step explanation:

we know that

In a right triangle, we have two complementary angles (their sum equal to 90 degrees)

If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa

<em>Example</em>

Suppose we have the right triangle ABC

The measure of angle C is 90 degrees

A and B are complementary angles

A+B=90°

therefore

sin(A)=cos(B)

sin(B)=cos(A)

Which of the polynomial equations cannot be solved using the quadratic formula?

xxMikexx [17]

Answer:

The polynomial equation that cannot be solved using the quadratic formula: Option2: $x^2-2x^3-5=0$

Step-by-step explanation:

First of all we have to learn what a quadratic polynomial is.

A polynomial or equation of degree 2 is called a quadratic equation. Quadratic formula is used to solve quadratic equations.

The quadratic equation is of the form:

$ax^2+bx+c = 0$

From the given options, only option 2 doesn't have degree 2 so it is not a quadratic polynomial.

Hence,

The polynomial equation that cannot be solved using the quadratic formula: Option2: $x^2-2x^3-5=0$

The absolute value of a number is added to the original number Kayla says the sum is always equal to 0 is she correct explain wh

ZanzabumX [31]

No she is not correct, because the absolute value of a number is its distance from zero on a number line. Therefore, you would take a number, say -1. The absolute value of this number is 1. So, add 1 and you would get 2. If I'm correct, 2 is not equal to zero. I hope this helps you out! ;)
