Jamison graphs the function ƒ(x) = x4 − x3 − 19x2 − x − 20 and sees two zeros: −4 and 5. Since this is a polynomial of degree 4
ANTONII [103]

Answer:

Jamison is not correct

Step-by-step explanation:

According to the Fundamental Theorem of Algebra, an nth degree polynomial has n roots.

These roots comprises of real roots and imaginary roots.

The given function is

f(x) =  {x}^{4}  -  {x}^{3}  - 19 {x}^{2} - x - 20

Based on the Fundamental Theorem of Algebra, this function should have four roots.

The graph of the function only reveals real zeros and not the imaginary zeros.

So aside −4 and 5, there are two complex zeros

How do you solve tan(sin^-1 x/2)? (show steps)
andrew11 [14]

First: Equations are solved. \tan\left(\sin^{-1}\dfrac x2\right) is an expression, and expressions can be simplified.

Now suppose y=\sin^{-1}\dfrac x2. Imagine a right triangle with one angle (not the one opposite the hypotenuse, of course) labeled y. This relation suggests that

\sin y=\dfrac x2

and under the hood, we're assuming that -\dfrac\pi2, because otherwise we wouldn't be able to properly alternate from x to y so seamlessly.

Now,

\tan\left(\sin^{-1}\dfrac x2\right)=\tan y

so the given expression is the same as the tangent of that same angle y.

If \sin y=\dfrac x2, then in the triangle, the leg opposite the angle y occurs with the length of the hypotenuse in a ratio of x to 2. By the Pythagorean theorem, the remaining side - call it z - satisifies

z^2+x^2=2^2\implies z=\sqrt{4-x^2}

and we have

\tan y=\dfrac xz=\dfrac x{\sqrt{4-x^2}}

Express 100,0000 as a power of 10
marusya05 [52]
I believe it is 10 and however many zeros there are and there's 6 so if I'm not mistaken the answer is 10^{6}.
