Answer:
-1Step-by-step explanation:
The iota is a complex notation represented by the letter i in complex number.
iota power 2 can also be written as;
i^2
In complex number, the square root of -1 is iota. This can be expressed as;
[tex]\sqrt{-1} = i[/tex]
Take the square of both sides
[tex](\sqrt{-1})^2 = i^2\\-1 = i^2\\Rearrange\\i^2 = -1[/tex]
Hence the iota power 2 is equal to -1
Which expression is not equivalent to

Answer:
B: 2x + 2 + x
Step-by-step explanation:
I just had this question and got it right
The solution is, 2x+ 2+x, is the expression which is not equivalent to
3x– 2.
What is an expression?An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
here, we have,
given that,
the expression is : 3x– 2
now, we have to find the expression which is not equivalent to 3x– 2.
now, we have, from the given options:
1.) x+x-1-1+x
= 3x - 2 , which is equivalent to 3x– 2.
2.) 2x+ 2+x
= 3x + 2 , which is not equivalent to 3x– 2.
3.) 3-x+ 2x-5 + 2x
= 3x - 2, which is equivalent to 3x– 2.
4.) 4x- 4-x+2
= 3x - 2, which is equivalent to 3x– 2.
Hence, The solution is, 2x+ 2+x, is the expression which is not equivalent to 3x– 2.

Write an expression for the sequence in
each table.
4.
Position
1 2 3 4 5 1
Value of Term 9
10 11 12 13
Answer:
[tex]a_n=n+9[/tex][tex]a_9=18[/tex]Step-by-step explanation:
Determining the expression for the sequence:
Given the sequence
10, 11, 12, 13
Here, the first element is:
a₁ = 10
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
computing the differences of all the adjacent terms
[tex]11-10=1,\:\quad \:12-11=1,\:\quad \:13-12=1[/tex]
The difference between all the adjacent terms is the same and equal to
[tex]d=1[/tex]
now substituting d = 1 and a₁ = 10 in the nth term
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_n=\left(n-1\right)+10[/tex]
[tex]a_n=n+9[/tex]
Determining the value of the 9th term
Given the nth term
[tex]a_n=n+9[/tex]
substituting n = 9 to determine the 9th term
[tex]a_9=9+9[/tex]
[tex]a_9=18[/tex]
Therefore, the vale of the 9th term is:
[tex]a_9=18[/tex]
Please helpz Your friend evaluates (12 + x) ÷ 6 for x = 6 and gets 13. Explain your friend's error.
Answer:
See explanation
Step-by-step explanation:
The correct answer is obviously 3 because if we substitute x = 6 into the expression we get ( 12 + 6 ) / 6. Using the order of operations, we get 18 / 6 = 3.
The friend likely didn't use the order of operations when evaluating. It's most likely that he substituted x = 6 into the expression and got ( 12 + 6 ) / 6. Instead of first adding 12 and 6, he divided 6 by 6 first to get 1, then added 12 to get 13.

8h 39min
+3h 25min
_________
h min
Answer:
12 hours and 4 minutes
Step-by-step explanation:
To solve first convert both terms to minutes. Do this by multiplying the number of hours by 60, then adding the remaining minutes. 8*60=480, then 480+39=519 minutes. Next, convert 3 hours and 25 minutes to 205 minutes. So now we have 519 minutes and 205 minutes, so add those together to get 724 minutes. Finally, convert back to hours to 12 hours and 4 minutes by dividing by 60.

Step-by-step explanation:
The population of a city increases by 3.1% per year. If this year's population is 119,000, what will next year's population be, to the nearest individual?
Answer:
the next year population is 122,689
Step-by-step explanation:
The computation of the next year population is as follows:
= This year population × increase percentage
= 119,000 × (1 + 0.031)
= 119,000 × 1.031
= 122,689
Hence, the next year population is 122,689
The above formula is applied so that the correct value of the population could come

The expression 8x + 12y represents the sum of Harry's and Lloyd's total wages, where x represents the number of hours Harry worked and y represents the number of hours Lloyd worked. What is another way to write the expression, and what can you conclude from rewriting it in this way?
Answer:
The rewritten is x + 1.5y.
It can be concluded that Lloyd earns $0.5 per hour more than Harry.
Step-by-step explanation:
Given;
8x + 12y
The expression can be rewritten by dividing it through by 8 as follows:
(8 / 8)x + (12 / 8)y = x + 1.5y
Therefore, the expression can be rewritten as x + 1.5y.
Since x represents the number of hours Harry worked and y represents the number of hours Lloyd worked, the new expression implies that Harry earns $1 per hour while and Lloyd earns $1.5 per hour. Therefore, it can be concluded that Lloyd earns $0.5 per hour more than Harry.
Which of the following situations best matches the data in the table?
Which type of graph is best suited for graphing the cost of a computer versus its speed?
Please help ASAP!!
Answer:
A: Line graph
Step-by-step explanation:
A pie chart is just percentages, so that wouldn't work. A box and whisker plot is for a number line, so that wouldn't work. A stem and leaf plot is for representing quantitative data in a graphical format, so that wouldn't work. The only logical choice is a line graph, since y could be the cost, and x could be the speed.

Will give brainliest to first right answer. Before a sale an items price was $28.00 then after being discounted the price was $14.60. What was the discount for the item? with a exact fraction
Answer:
The discount was [tex]47\frac{6}{7}[/tex]%
Step-by-step explanation:
In order to find out the discount will have to do the following.
First find out what part of the origin price was taken of, so we create a fraction with the denominator being the original price and the numerator being the difference between the original price and the discount price. So we do.....
[tex]\frac{28.00-14.60}{28.00} = \frac{2800 - 1460}{2800} = \frac{1340}{2800} = \frac{67}{140}[/tex]
Now we have to find a fraction with the same value but with the denominator being a 100, so we do.....
[tex]\frac{67 / 1.4}{140/1.4}= \frac{47\frac{6}{7} }{100}[/tex]
From this we know that the the discount in percentages will be equal to [tex]47\frac{6}{7}[/tex]%
Answer:
52.1428571429
Step-by-step explanation:
14.60 × 100 = 1460
1460 ÷ 28 = 52.1428571429
