Given a polynomial f(x), if (x + 2) is a factor, what else must be true?
1 answer:
Given:
(x+2) is a factor of polynomial f(x).
To find:
The correct statement.
Solution:
If (x-c) is a factor of polynomial f(x), then c is a zero of the polynomial and f(c)=0.
We have, (x+2) is a factor of polynomial f(x).
On comparing (x-c) and (x+2), we get
It means, -2 is a zero of the polynomial f(x) and the value the polynomial at x=-2 is 0, i.e.,
Therefore, the correct option is d.

Answer:
Independent events
Step-by-step explanation:
Given that:
Ramiro draws a marble from a jar without replacement and then flips a coin
Let be the event that Ramiro draws a marble without replacement and;
Let be the event of flipping a coin.
Let's have an analogy so that we can better understand the concept of independent and dependent events.
Consider a random experiment in which a marble is drawn from a jar without replacement and a fair coin is flipped together.
The event does not in any way affect the event
of a head or a tail showing up in a flip of a coin.
Therefore, we say that and
are independent events.
Suppose the event affects or influence the event
, then we can say they are dependent events.
