Factoring f(x) would give a factor (x-1-2i), so you can divide f(x) by this, leaving (x-3)(x+4)(x-1+2i), so the other roots are:
x=3
x=-4
x=1-2i
Answer:
sqrt(50)
Step-by-step explanation:
Since it is a right triangle, we can apply the Pythagorem Theorem.
a^2 + b^2 = c^2
25 + 25 = c^2
50 = c^2
c = sqrt(50)

5. ∠2 = ∠3 CPCTE
Answer:
The sine and cosine functions have several distinct characteristics: They are periodic functions with a period of 2π. ... The graph of y = sin x is symmetric about the origin, because it is an odd function. The graph of y = cos x is symmetric about the y-axis, because it is an even function.
