Simplify each of the following powers of i. i^99=
Scorpion4ik [409]
I= sqrt (-1)

If the power is
- even then the value could be -1 or 1
-odd then the value could be -i or i

99 is odd so now is
-i if (99+1)/2 is even or is
i is (99+1)/2 is odd

Now check (99+1)/2= 100/2= 50,
50 is even so

Which of the following equations describes the line shown below , check all that apply
Bond [772]
The line is passing through the y-axis at 3. The slope of the line is 3.
So your equation would be y = 3x + 3.

Now solve A through F to see which equation(s) matches the line.

A. y + 6 = 3(x + 3)
     y + 6 = 3x + 9
     y = 3x + 3

B. y + 6 = 3(x + 1)
     y + 6 = 3x + 3
     y = 3x - 3

C. y - 6 = 3(x - 3)
     y - 6 = 3x - 9 
     y = 3x - 3

D. y - 6 = 3(x - 1)
     y - 6 = 3x - 3
     y = 3x + 3

E. y = 3x + 2

F. y = 3x + 3

Which letters equaled y = 3x +3?
A, D, and F.

The equations that describe the line are A, D, and F.
