Answer:
The real solution is
.
Step-by-step explanation:
while ![\sin(\frac{\pi}{2})=1](https://tex.z-dn.net/?f=%5Csin%28%5Cfrac%7B%5Cpi%7D%7B2%7D%29%3D1)
So the equation becomes:
![-64=(2(0)+2i(1))^n](https://tex.z-dn.net/?f=-64%3D%282%280%29%2B2i%281%29%29%5En)
![-64=(0+2i)^n](https://tex.z-dn.net/?f=-64%3D%280%2B2i%29%5En)
![-64=(2i)^n](https://tex.z-dn.net/?f=-64%3D%282i%29%5En)
We know that
. So let's see what
gives us:
.
is the result we wanted.
is therefore a solution.

Ric received $3.00 of change. First, you multiply 4 by $1.25 to get $5.00. Then, the pen cost $2.00 because 2 is 2/5 of 5. Next, you add 2 and 5 together to get $7.00. Lastly, you subtract 7 from 10 ($10.00-$7.00) to get your change, $3.00. Hope it helps :)
Answer:
x=1/2 y =1
Step-by-step explanation:
(-4x+2y)/2x5=0/2x5
10x+3y=8
(-2x+y)x5=0
10x+3y=8
-10x+5y=0
10x+3y=8
8y=8
y=1
x=1/2
