Answer & Explanation:
"The Magical Number Seven, Plus or Minus Two: Some Limits on Our Capacity for Processing Information" is one of the most highly cited papers in psychology. It was published in 1956 in Psychological Review by the cognitive psychologist George A. Miller of Harvard University's Department of Psychology.
Answer:
you cannot subtract 12x² from -14x they are not "like" terms
Step-by-step explanation:
Answer:
<u>The correct answer is that 4√- 2 is the simplest radical form of this mathematical expression and 8i (i = imaginary unit) is the solution if we want to find out the square root of a negative signed number.</u>
Step-by-step explanation:
1. Let's write in a mathematical expression the information given:
Sum square root of -2 and the square root of - 18
√- 2 + √ - 18
√- 2 + √ 9 . - 2 ( 9 * -2 = - 18)
√- 2 + 3 √ - 2 (√ 9 = 3)
4 √- 2
This is the simplest radical form of this mathematical expression. If we want a concrete number, we should remember that if we refer to the imaginary numbers we can find the solution for √-2 = 2i, or for any other negative number, where i is the imaginary unit. This unit can be used for the development of the square root of negative signed numbers.
Then,
4 √- 2 = 4 (2i) = 8i
<u>The correct answer is that 4√- 2 is the simplest radical form of this mathematical expression and 8i (i = imaginary unit) is the solution if we want to find out the square root of a negative signed number.</u>
Before budget change :
Maintenance = 1 - 1/3 - 1/3 - 1/4 = 1/12
After budget change :
Maintenance = 1 - 1/3 - 1/8 - 1/4 = 7/24
Difference in budget for maintenance = 7/24 - 1/12 = 5/12
X= 41.5085
To the nearest hundredth;
x= 41.51
