Answer:
-1
Step-by-step explanation:
i^0 =1
i ^1 = i
i^2 =-1
i^3 = -i
It cycles through by 4
so i^4 is back to 1
Take the power , divide by 4 and look to the chart for the remainder
If the remainder is 0 then i to that power is 1
1 i
2 -1
3 -i
i^22
Take 22/4 = 5 remainder 2
The remainder is 2 so i^22 = -1
y= 1/10x - 6
Which if you plug in 70 for x, y equals 1.
Rebecca has $1 and Tim has $70, together they have $71.
Answer:
y = 20 - x
Step-by-step explanation:
Perimeter of a rectangle = 40 units
2 * ( length + width) = 40
2* (x + y) = 40 {Divide both sides by 2}}
x + y = 40/2
x + y = 20 {Subtract x from both sides}
y = 20 - x
Answer:
12 5/8 tons were delivered by the third truck
Step-by-step explanation:
25 = 6 4/8 + 5 7/8 + x
25 = 12 3/8 + x
- 12 3/8
12 5/8 = x
