If i = √-1 ,
then ...
i² = (√-1)² = -1
i³ = - √-1 = -i <== the answer to the question
i⁴ = (i²) · (i²) = (-1) · (-1) = 1
and then the whole thing starts over again, for higher powers of i .
Answer:
this basically means that whenever x is increased then y will decrease, but if x is decreased y will increase.
Step-by-step explanation:
If there are 120 total songs and 20% are rap, then your equation is
120 * 20% = 24 rap songs
If 24 of the songs are rap and the rest are rock, then
120 - 24 = 96 rock songs
<span>take 5x as a factor of each term
5x(x^2 -4x - 12)
you now need to factor the quadratic...
hope it helps
