| - 8 | means that -8 is 8 units far away from 0.
We use the units to answer, so we say that | - 8 | = 8.
The Absolute Value has defines and they are for basics.
These are just basics for absolute value.
Therefore, | - 8 | = 8.
Answer:
X= -11/6. Y=-40/9
Step-by-step explanation:
Answer:
X= 6i
Step-by-step explanation:
We have the following equation:
y^3 - 3y^2 + X - 1 = -i (1),
where X is the missing term.
So, we know that y = 1 + i. Where i = sqrt(-1).
Substituting y = 1 + i in the equation (1):
(1 + i)^3 - 3(1 + i)^2 + X - 1 = -i
(1)^3 + 3(i)(1)^2 + 3(1)(i)^2 + (i)^3 - 3(1 + 2(1)(i) + (i)^2) + X - 1 = -i
Simplifying:
1 + 3i -3i - i - 3(1 + 2i -1) + X - 1 = -i
1 - i -6i + X - 1 = -i
-i - 6i + X = -i
- 6i + X = 0
X= 6i
So the missing term is X= 6i
Answer:
Barbers= 5.41= 6 barbers
Step-by-step explanation:
Giving the following formula:
Haircuts per hour= 12
Number of hours= 10
Haircuts needed= 650
<u>First, we need to calculate the number of haircuts each barber can make per day:</u>
Haircuts per barber a day= 12*10= 120 haircuts
<u>Now, the number of barbers needed:</u>
Barbers= total haircuts / haircuts per day
Barbers= 650/120
Barbers= 5.41= 6 barbers
