Which simplifications of the powers of i are correct? there may be more than one correct answer. select all correct answers. i8=1 i14=1 i28=i i5=i i27=−i

i^8, i^5 and i^27 are True.

Step-by-step explanation:

i^2 = -1 , i^3 = -i, i^4 = 1, i^5 = i , i^6 = -1, i^7 = -i, i^8 = 1   and so on

i^8 = i^4 * i^4 = 1*1 = 1  TRUE

i^14 = i^7 * i^7 = -i*-i = i^2 = -1 NOT TRUE

i^28 = i^14 * i^14 ==  -1 * -1 = 1  NOT TRUE

i^5 = i   TRUE

I^27 = i^8 * i^8 * i^8 * i^3 = 1 * i^3 = -i  TRUE

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

there is no points to select.
