Reviewing Imaginary Numbers. Simplify I^12
Answers
Answer:
1
Step-by-step explanation:
\(i^{12}= i^{2} *i^{2} *i^{2} *i^{2} *i^{2} *i^{2}\)
Remember that \(i^{2}=-1\)
Plug it in:
\(i^{12}= (-1)^{2} *(-1)^{2} *(-1)^{2} *(-1)^{2} *(-1)^{2} *(-1)^{2}\)
\(=1*1*1*1*1*1\)
\(=1\)

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

I need help on a b and function 2
I dont get it
Answers
Answer:
For A: The first function has a greater ROC
For B: The first function has a negative slope
Step-by-step explanation:
Explication for A:
We already know that the R.O.C. (slope) is 2 for the first function, so all we need to do is substitute the values in the table into the following formula: y2-y1/x2-x1
after substituting: (-3-(-6))/(0-(-1))
simplify 3/1=3, since the ROC is 3, the second equation has a greater ROC than the first
Explanation for B:
The first function described is f(x)=20-3.5x
This is because the y intercept is the starting point, or how much money she has in the gift card. She spends 3.5 dollars per week, so we add a variable to represent the number of weeks, and its negative since she is spending, not earning. We also know that the slope is negative since y is decreasing as x is increasing, on the table.
The second function described is c(m)=5x+10
This is because the equation represents the total cost of renting a calculator, so both terms are positive.

Answer:
The sample must represent the target population
Step-by-step explanation:
To figure out the answer to can eliminate the answers that don't make sense.
The question is A random sample of people is chosen to participate in a survey. For the survey results to be considered valid, which must be true of the random sample?
Lets look at our answers-
A: The sample must be the same size as the population.
That does not make sense as the answer because the sample doesn't always have to be the same size as the population. So let's cross that out.
B: The sample must represent the target population.
That Makes the most sense because if you have a survey and your trying to get people opinion the sample must represent the target.
C: The sample must be biased.
This answer also makes a bit sense but not as much as B.
D: The sample must be a group separate from the population.
This is wrong because if your trying to get multiple peoples opinion you don't need a specific or separate group from the population.
So, Our answer is B: The sample must represent the target.

Answers
Using the point-slope form: y - y₁ = m(x - x₁)
Plug in the values: y - 3 = -2(x - (-1))
Simplify: y - 3 = -2(x + 1)
Now, we can find the y value of the point:
y - 3 = -2(-1 + 1)
y - 3 = 0
y = 3
So, the y value of the point is 3.

Tell me what he did RIGHT!
Tell me the mistake that Bobby Joe made
Tell me the correct way to combine like terms in this expression
6x + 5x + 2y
11x + 2y
13xy
Answers
Answer:
Bobby added 6x and 5x which was correct because they're like terms
Bobby then combined 11x and 2y which was incorrect, they're not like terms because they have different variables
to correct his mistake he has to stop simplifying the equation at 11x + 2y because that is as far as you can simplify it
Bobby Joe has done combination properly till \(11x + 2y\) because, \(6x + 5x\) are like terms and has common variable \(‘x’\) but, he messed up when he started combining \(11x + 2y\)because, they are not at all like terms and doesn't have common variable. So, to recover it he should stop combining till \(11x + 2y\).
