-64=(2cos(pi/2)+2i sin(pi/2))^n..... n=??​
zvonat [6]

Answer:

The real solution is n=6.

Step-by-step explanation:

\cos(\frac{\pi}{2})=0 while \sin(\frac{\pi}{2})=1

So the equation becomes:

-64=(2(0)+2i(1))^n

-64=(0+2i)^n

-64=(2i)^n

We know that 2^6=64. So let's see what n=6 gives us:

(2i)^6=64i^6=64i^4i^2=64(1)(-1)=-64.

-64  is the result we wanted.

n=6 is therefore a solution.

Complete the equation of the graphed linear function in point-slope form.
BlackZzzverrR [31]
They are using the point (2, 8) to write this equation.  You know that because of the "y-8" in the equation, and also because it's bolded! lol.  Anyways, what's missing is the slope and the x value from our point.  The slope is -2.  Find this by picking 2 points on the line and putting those into the slope equation.  Use the bolded point and the x-intercept: (2,8) and (6,0):m= \frac{0-8}{6-2}= \frac{-8}{4}=-2.  As stated earlier the x coordinate in the bolded point is 2.  So our equation is y-8=-2(x-2).  And there you Go!

Let f(x) = x+2/x+6 <br> f^-1(-6) =
GREYUIT [131]

We can explicitly find the inverse. If f^{-1}(x) is the inverse of f(x), then

f\left(f^{-1}(x)\right) = \dfrac{f^{-1}(x)+2}{f^{-1}(x)+6} = x

Solve for the inverse :

\dfrac{f^{-1}(x) + 2}{f^{-1}(x) + 6} = x

\dfrac{f^{-1}(x) + 6 - 4}{f^{-1}(x) + 6} = x

1 - \dfrac4{f^{-1}(x) + 6} = x

1 - x = \dfrac4{f^{-1}(x) + 6}

f^{-1}(x) + 6 = \dfrac4{1-x}

\implies f^{-1}(x) = \dfrac4{1-x} - 6

Then when x = -6, we have

f^{-1}(-6) = \dfrac4{1-(-6)} - 6 = \dfrac47-6 = \boxed{-\dfrac{38}7}

Alternatively, we can first solve for x such that f(x) = -6. Then taking the inverse of both sides, x = f^{-1}(-6). (The difference in this method is that we don't compute the inverse for all x.)

We have

\dfrac{x+2}{x+6} = -6

x + 2 = -6 (x + 6)

x + 2 = -6x - 36

7x = -38

\implies x = \boxed{-\dfrac{38}7}
