8.45 as a mixed number

Vlad [161]

A mixed number is a combination of a whole number and a fraction, so in this case we have 8 as the whole part and 0.45 as the fraction, 0.45 is equal to 45/100, and that fraction can be simplified as well, lets see:
8.45 = 8 45/100
= 8 9/20

Find an nth degree polynomial function with real coefficients satisfying the given conditions.

damaskus [11]

Step-by-step explanation:

Our roots are 3, and i so our roots form

will be

$(x - 3)(x - i)$

Since i is one root, it conjugate, must be the other.

so we have

$(x - 3)(x - i)(x + i)$

Simplify

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

${x}^{3} - 3 {x}^{2} + x - 3$

So the function is

$x {}^{3} - 3 {x}^{2} + x - 3$
