Answer:

-1

Step-by-step explanation:

Note that i+i^2+i^3+i^4 = i-1-i+1 = 0, and this means that every 4 terms, the terms cancel to 0. Therefore, by taking modulo 4, we only need to find i^{257}+i^{258}+i^{259} = i-1-i = -1 since $i$ has a cycle of 4.

A line passes through (4, 5) and (8, 9). Which equation best represents the line?
Alborosie

Answer:

A) y=x+1

Step-by-step explanation:

y-y1=m(x-x1)

m=(y2-y1)/(x2-x1)

m=(9-5)/(8-4)=4/4=1

y-5=1(x-4)

y-5=x-4

y=x-4+5

y=x+1
