Answer:
A
Step-by-step explanation:
To find the value you can just find 12% of each number (trial and error), until one of them gives you 90 as an answer:
A) 750
750 * 0.12 = 90
B) 1080
1080 * 0.12 = 129.6
C) 360
360 * 0.12 = 43.2
D) 1168
1168 * 0.12 = 140.16
This tells you that 90 is 12% of the 750, and that is why it is your answer
I hope this helps!

Answer: -i</h3>
========================================================
Explanation:
i = sqrt(-1)
Lets list out the first few powers of i
- i^0 = 1
- i^1 = i
- i^2 = -1
- i^3 = i*i^2 = i*(-1) = -i
- i^4 = (i^2)^2 = (-1)^2 = 1
By the time we reach the fourth power, we repeat the cycle over again (since i^0 is also equal to 1). The cycle is of length 4, which means we'll divide the exponent over 4 to find the remainder. Ignore the quotient. That remainder will determine if we go for i^0, i^1, i^2 or i^3.
For example, i^5 = i^1 because 5/4 leads to a remainder 1.
Another example: i^6 = i^2 since 6/4 = 1 remainder 2
Again, we only care about the remainder to find out which bin we land on.
-------------
Turning to the question your teacher gave you, we have,
739/4 = 184 remainder 3
So i^739 = i^3 = -i
<h3>
-i is the final answer</h3>
--------------
Side notes:
- if i^a = i^b, then a-b is a multiple of 4
- Recall that the divisibility by 4 trick involves looking at the last two digits of the number. So i^739 is identical to i^39.
Answer:(-2,3.5)
Step-by-step explanation: Add the endpoints and divide by two for the x-values and the y-values
Answer:
x<4.5
Step-by-step explanation:
y
=(x-2)^2 +2 {x<4.5}
add the power and then divide by 2 you get 4.5
