Answer:

$\displaystyle \frac{1}{2}(x^3-2x^2-5x+6)$

Step-by-step explanation:

Polynomials

The polynomial whose graph is shown is of third degree because it has three real roots. The roots of a polynomial are the values of x that make the expression equal to zero. We can see it happens three times in the graph provided. The roots or zeros are

x=-2, x=1, x=3

The factored form of a polynomial whose roots $x_1, x_2, x_3$ are known is

$a(x-x_1)(x-x_2)(x-x_3)$

We know the value of the roots, thus the polynomial is written as

$a(x+2)(x-1)(x-3)$

We need to find the value of a. We do that by replacing the value of x=0 and finding a that makes f(0)=3 (as seen in the graph). Thus

$a(0+2)(0-1)(0-3)=3$

$a(2)(-1)(-3)=3$

$a(6)=3$

$\displaystyle a=\frac{3}{6}$

$\displaystyle a=\frac{1}{2}$

Thus the factored form of the polynomial is

$\displaystyle \frac{1}{2}(x+2)(x-1)(x-3)$

Let's multiply all the factors

$\displaystyle \frac{1}{2}(x+2)(x-1)(x-3)$

$\displaystyle \frac{1}{2}(x^2+2x-x-2)(x-3)$

$\displaystyle \frac{1}{2}(x^2+x-2)(x-3)$

$\displaystyle \frac{1}{2}(x^3-3x^2+x^2-3x-2x+6)$

$\boxed{ \displaystyle \frac{1}{2}(x^3-2x^2-5x+6)}$

if each interior angle of a regular convex polygon is three times the measure of each exterior angle, what kind of polygon is it

Julli [10]

The interior angle of a regular polygon is equal to 180(n - 2)/n. The exterior angle is always equal to 360/n. Using the given relationship from the item above, the equation that can be formed is,

180(n - 2)/ n = 3(360/n)

The value of n from the equation is 8. The polygon with 8 sides is an octagon.

Answer: OCTAGON

Solve. 34(x−8)=−12 x=− 26/3 x = 10 x=22/3

puteri [66]

I believe the answer would be... x= 130/17 for 34(x-8)=-12

I am really sorry, but I am not sure how to answer the rest

Hoped I helped with the first part of it!

Have a great day/night!
