Consider the following circle with center at point O.

Maurinko [17]

Answer:

Chord: RT (and RS and TU, but those are also diameters)

Diameter: RS or TU

Radii: OU, OS, OT, or OR

Step-by-step explanation:

Chord: A line segment joining two points on a curve. Doesn't have to cross the center. (AKA, they have to touch the outer edge of the circle.)

Diameter: Chord that crosses the center of the circle(All examples given above cross center O)

Radius: Line segment that goes from the center of a circle to an endpoint that lies on the circle.

Find all rational solutions of the equation x8−4x5+13x3−7x+1=0.

drek231 [11]

Answer:

The rational roots of the equation are:

x= -1.10355

x= 0.148953

x= 0.706883

x= -1

Step-by-step explanation:

We have to find the rational solutions of the algebraic equation:

$x^8-4x^5+13x^3-7x+1=0.$

This equation could also be written as:

$(x+1)(x^7-x^6+x^5-5x^4+5x^3+8x^2-8x+1)=0$

for finding the roots of the equation we have to find the possible values of x.

Clearly the equation has 8 roots as the degree of the equation is 8.

from the graph of the following function we could see that the rational roots of the function are:

x= -1.10355

x= 0.148953

x= 0.706883

x= -1

The rest 4 roots of the equation are the complex roots.
