0.45 Isn't Equal To Any Of These Fractions But It Is Equal To 45/100
Answer:
it must also have the root : - 6i
Step-by-step explanation:
If a polynomial is expressed with real coefficients (which must be the case if it is a function f(x) in the Real coordinate system), then if it has a complex root "a+bi", it must also have for root the conjugate of that complex root.
This is because in order to render a polynomial with Real coefficients, the binomial factor (x - (a+bi)) originated using the complex root would be able to eliminate the imaginary unit, only when multiplied by the binomial factor generated by its conjugate: (x - (a-bi)). This is shown below:
where the imaginary unit has disappeared, making the expression real.
So in our case, a+bi is -6i (real part a=0, and imaginary part b=-6)
Then, the conjugate of this root would be: +6i, giving us the other complex root that also may be present in the real polynomial we are dealing with.
Depending on how big the center is, I would say 15.
I hope this helped!
Answer:
8
Step-by-step explanation:
Absolute Value (| |) is the number of spaces away from 0. -8 is 8 spaces away from 0 and 8 is 8 spaces away from 0.
Hope this helps plz mark brainliest if correct :D
