Answer: \pm1,\pm3,\pm5, \pm15

Step-by-step explanation:

We can list the possible rational roots of this polynomial using the Rational Root Theorem. This theorem states that all the possible rational roots of an equation follow the structure \frac{p}{q}, where <u>p is any of the factors of the constant term and q is any of the factors of the leading coefficient</u>.

In this example, -15 is the constant term and 1 is the leading coefficient (x^4 has a coefficient of 1).

The factors of -15 are \pm1,\pm3,\pm5, \pm15, while the factors of 1 are \pm1. <em>p </em>is can be any one of the factors of -15, while <em>q</em> can be any of the factors of 1.

\frac{\pm1,\pm3,\pm5, \pm15}{\pm1}

The possible roots can be any of the numbers on the top divided by any of the numbers on the bottom. Since dividing by 1 or -1 won't change any of the numbers on the top, the rational roots of this function are \pm1,\pm3,\pm5, \pm15.

Solve for x using the Quadratic Formula: x2 + 4x + 4 = 0<br> -b + Vb2 - 4ac<br> x=<br> 2a
Irina18 [472]

Answer:

x = -2.

Step-by-step explanation:

In this case, a is 1, b is 4 and c is 4.

-4 plus or minus the square root of 4^2 - 4 * 1 * 4 divided by 2 * 1 = -4 plus or minus the square root of 16 - 16 / 2 = -4 plus or minus the square root of 0 / 2 = -4 / 2 = -2.

x = -2.

Hope this helps!

In right triangle ABC, the measure of angle A is 25 degrees, angle c is 90 degrees, and AB = 1. what is the length of AC?
Allisa [31]

Answer:

b= 0.9

Step-by-step explanation:

first you find angle B: 180-90-25=65

then you will do law of sine- sin A/a=sin B/b=sin C/c

sin(90)/1=sin 65/b

sin(90)*b=sin(65)*1

sin(90)*b=0.9

b=0.9/sin(90)

b= 0.9
