Answer:
i is defined as the square root of -1.
i^2 = -1
i^3 = -i
i^4 = 1
Following the pattern, we see that i^40 = 1, so i^38 is two above, or equal to -1.
So, i^38 = -1.

Step-by-step explanation:
first you put the numbers in order from least to greatest
1,1,1,1,2,2,2,4,12,13,15,15,15,16,16
next find the middle number(s)
1,1,1,1,2,2,2,<em>4</em>,12,13,15,15,15,16,16
the middle number is your median
*if you have 2 middle numbers just add the then divide it by 2 to find the median
Answer: Angelo is 13 years old.
Aaron is 15 years old
Alfred is 34 years old
Let x represent the age of Angelo.
Let y represent the age of Aaron.
Let z represent the age of Alfred
The sum of three guys ages is 62. It means that
x + y + z = 62 - - - - - - - - - - -1
Angelo is two years younger than Aaron. It means that
x = y - 2
Alfred is four years older than twice Aaron's age. It means that
z = 2y + 4
Substituting x = y - 2 and z = 2y + 4 into equation 1, it becomes
y - 2 + y + 2y + 4 = 62
4y + 2 = 62
4y = 62 - 2 = 60
y = 60/4 = 15
x = y - 2 = 15 - 2
x = 13
z = 2y + 4 = 2 × 15 + 4
z = 34
The answer would be b, 8:13
6000
first you do 40000-28000 =12000 that means we have 12000 left
12000÷2 because the shirt equals 2 to give 6000
Hope this helps!
