Three roots of a fifth degree polynomial function f(x) are –2, 2, and 4 i. Which statement describes the number and nature of al
bagirrra123 [75]

The correct option is f(x) has three real roots and two imaginary roots.

Given

Three roots of a fifth-degree polynomial function f(x) are –2, 2, and 4 i.

<h3>Complex conjugate</h3>

The complex conjugate of a complex number is the number with an equally real part and an imaginary part equal in magnitude but opposite in sign.

It is given that the roots of the fifth-degree polynomial function are -2, 2, and 4+i.

Since the degree of f(x) is 5, therefore there are 5 roots of the function either real or imaginary.

According to the complex conjugate root theorem, if a+ib is a root of a polynomial function f(x), then a-ib is also a root of the polynomial f(x).

Since 4+i is a root of f(x), so by complex conjugate rot theorem 4-i is also a root of f(x).

From the given data the number of real roots is 2 and the number of 2. The number of complex roots is always an even number, so the last root must be a real number.

Therefore, the correct option is f(x) has three real roots and two imaginary roots.

The sides of a triangle have lengths of x, x + 5, and 25. If the longest side is 25, which of the following values of x would ma
Amiraneli [1.4K]
In a right angle, the sum of the squares of the two shorter sides is equal to the square of the longest side.
Here, the longest side is 25, the shorter sides are x and x+5.

x^2+(x+5)^2=25^2 \\&#10;x^2+x^2+10x+25=625 \\&#10;2x^2+10x+25=625 \ \ \ |-625 \\&#10;2x^2+10x-600=0 \ \ \ |\div 2 \\&#10;x^2+5x-300=0 \\&#10;x^2+20x-15x-300=0 \\&#10;x(x+20)-15(x+20)=0 \\&#10;(x-15)(x+20)=0 \\&#10;x-15=0 \ \lor \ x+20=0 \\&#10;x=15 \ \lor \ x=-20&#10;

The length of a side must be a positive number, so x=15.
The answer is C.

Whats the value of u+5v-w,if u=6, and w=9?
Vitek1552 [10]
To solve this we need only substitute values of u and w, and then calculate.

<span>u+5v-w = 6 + 5v - 9 = 5v +6 - 9 = 5v - 3</span>

The vertices of a right triangle are (–5, –2), (–1, –6), and (–5, y).
Gemiola [76]
I would say C: -2 because 2 sides have to match and one side has to be either smaller or bigger than the other 2 sides
