Step-by-step explanation:

y = mx + b

y = -7x + 7

this assumes m = - 7 , it got chopped off, otherwise what ever slope is change the first 7 for that number.

-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.
