Answer:
40cm² there you go
Step-by-step explanation:
Area =side×side so 8×5=40
Answer:
-i
Step-by-step explanation:
i^0=1
i^1=i
i^2=-1
i^3=-i
i^4=1
This repeats so we want to see how many 4 factors of i there is in i^(23) which is 5 with a remainder of 3.
So i^(23)=i^3=-i.
i^(23)=i^(5*4+3)=(i^4)^5 * (i^3)=(1)^5 * (-i)=1(-i)=-i.

I'm going to be honest, I don't know how to show the work. You wouldn't do long division because it doesn't go into decimals.
Answer:
Correct choice is 4, f(6) = 15
Step-by-step explanation:
f(6) means x = 6. If you look at the piecewise function, x = 6 meets the criteria for the second equation which is just 15. You need the first equation ONLY if x is less than 4.
Answer:
x = -11/4
Step-by-step explanation:
4x - 2 = -13
(add 2 on both sides)
4x - 2 + 2 = -13 + 2
4x = -11
(Divide 4 on both sides)
4/4x = -11/4
x = -11/4
