Answer:
f(x) = x^2 (x + 7i)(x - 7i)
Step-by-step explanation:
Factoring out x^2 gives ...
f(x) = x^2(x^2 +49)
The factor with 49 can be considered to be the difference of two squares, where one of the squares is -49. Then its square root is ±7i, and the factorization of that term is ...
x^2 +49 = (x +7i)(x -7i)
So, the overall factorization of f(x) is ...
f(x) = x^2(x +7i)(x -7i)
We analyze the linear function to find that it has equation
. Drawing the line, we find that it
will intersect the circle at negative and positive x-coordinates.We can prove this by
substituting into the given equation:
Hence,
or
, so there are both positive and negative values for
.

Answer:
Yo, the answer would be 95
Step-by-step explanation:
The area of a circle is
A=(pi)r^2 OR A=(pi)d (d is diameter)
This means you have to square 5.5, that means multiply it by itself.
5.5*5.5
This is 30.25 which you then multiply by pi
30.25*3.14=94.985
If you round to the nearest hundredth, you get 95. Cheers
