If a polynomial function f(x) has roots 3+ V5 and -6, what must be a factor of f(x)?

Mathematics

Mkey [24]3 years ago

Answer:

Step-by-step explanation:

Radicals and imaginary numbers ALWAYS come in pairs when it comes to factors of polynomials. This is the called the conjugate theorem. If we are given a solution/root/zero that is

x = 3 + √5, then its conjugate is x = 3 - √5. Going backwards from the solution to the factor, we utilize the Zero Product Property and get

(x - (3 - √5)) which simplifies to (x - 3 + √5). if you are looking for the conjugate of the given zero, the choice you want is the second one down.

Answer:

  7/3

Step-by-step explanation:

The point at the right end of segment 5 is 7 units above and 3 units to the right of the point at the left end. The slope is the "rise" divided by the "run":

  slope = m = rise/run = 7/3

The slope of segment 5 is 7/3.

Don't spam answer only if you know What is the measure of angle x? Enter your answer in the box​
Fudgin [204]

Answer:

The angle of x is 83°

Step-by-step explanation:

A straight line has a total of 180°. That means if you can figure out what the third angle on the bottom is (the one in the middle) you can add 41 to it and subtract that from 180. Since all the lines are straight you can say that the middle angle on the bottom is the same as the middle angle on the top. So:

180° - (41° + 56°) = 83°

WZ←→− is tangent to circle O at point B.
Assoli18 [71]

A tangent (here WZ in the question) to any circle (here O in the question) is a line segment that touches the circle at only one point (here B in the question) on circumference of circle, and the radius of the circle (here OB in the question) through this point is always perpendicular to that particular tangent.

In other words, Tangent (WZ) and Radius (OB) of any circle (O) always make a Right angle at point of intersection (B) on its circumference.

It means angle ∠OBZ would be a Right angle i.e. 90 degrees.

So, option B i.e. 90 degrees is the final answer.

If f(x)=x/2-2and g(x)=2x^2+x-3 find (f+g) (x)
olya-2409 [2.1K]

Answer:

C   2x^2 + 3/2x -5

Step-by-step explanation:

f(x)=x/2-2

g(x)=2x^2+x-3

(f+g) (x)=x/2-2+2x^2+x-3

Combine like terms

           2x^2 + 3/2x -5
