Answer:
Its i
Step-by-step explanation:
I got it right on the test
The value of the given expression is i.
We want to simplify the expression [tex]i^{41}[/tex].
What is an imaginary number?An imaginary number is a real number multiplied by the imaginary unit i, which is defined by its property i² = −1. The square of an imaginary number bi is −b².
The given expression [tex]i^{41}[/tex] can be written as [tex](i^{4})^{10}.i[/tex]
The value of i²=-1, then [tex]i^{4}[/tex]= i².i²=(-1)(-1)=1
Now, [tex](1)^{10}.i=1\times i=i[/tex]
Therefore, the value of the given expression is i.

If a club charges dues of $200 a year, it will have 50 members. For each $5 it raises its dues, it loses a member. USE AN EQUATION to determine what the club should charge to maximize its income from dues.
Answer:
The value is [tex]y = \$ 225[/tex]
Step-by-step explanation:
From the question we are told that
The amount charge per year is [tex]k = \$ 200[/tex]
The number of members it will have at this amount is [tex]n = 50[/tex]
The amount amount increase that will lead to the loss of a single member is [tex]z = \$ 5[/tex]
Generally the total amount the club would obtain from its members is mathematically represented as
[tex]I = Amount \ due\ paid * Number \ of members[/tex]
Now let x denote the number of member lost
Hence
[tex]I = (k + zx) (n-x )[/tex]
=> [tex]I = (200 + 5x) (50-x )[/tex]
=> [tex]I = 10000+50x-5x^2[/tex]
Thus the number of members that be removed to give the maximum income from dues is obtained by differentiating the above equation and equating it to zero
[tex]\frac{dI}{dx} = 50-10x[/tex]
=> [tex] x = 5[/tex]
So from [tex]I = (200 + 5x) (50-x )[/tex] we have
[tex]I = (200 + 5 (5)) (50-5 )[/tex]
[tex]I = \$ 10125 [/tex]
So the amount the club should charge is
[tex]y = \frac{10125}{50 - 5}[/tex]
[tex]y = \$ 225[/tex]

Answer: Mr. Lee’s entire face crinkles and lights up when he smiles.
Step-by-step explanation:
Mr. Lee’s entire face crinkles and lights up when he smiles. Option C is correct.
Given that,
From the sentences, we have to determine the sentence that emphasizes the engaging details.
Content created by someone who is enthusiastic about the subject they are writing about is the most engaging content. If you write with passion and explain to readers why you are passionate, you might be able to persuade them to love your company as much as you do.
Here,
Option A and Option B is incorrect because the sentence describes different entities over the face.
While in option C engaging sentence the smile tends to bring crinkles and lights up the face.
Thus, Mr. Lee’s entire face crinkles and lights up when he smiles. Option C is correct.

A question asks: How many hours per week do you watch television? The respondent can answer in minutes and/or hours. What would be the best numerical summary of data from 300 participants? A. Mean, standard deviation, and range B. Median, IQR, and range C. Number and percent of total for each response option D. A or B depending on the distribution of the sample E. B and C
Answer: D. A or B depending on the distribution of the sample
Step-by-step explanation:
Given: A question ask about how many hours per week do you watch television?
Total participants = 300
Since all participants are different , so have their own answer to this question in numerical terms.
We use proportion or percentage to summarize data if data is categorical, but here data is numerical (continuous).
here , we can use either mean or median ( if it has outliers).
For this we need to check the distribution of the data, if it is normal then Mean, standard deviation, and range would be a better option (as mean is the best measure of tendency)otherwise Median, IQR, and range would be a better option .
hence, the correct option is D. A or B depending on the distribution of the sample

A standard number cube is rolled. Calculate: P(rolling 1 or 3)
Answer:
the probability is:
P(A) 2/6 =1/3
Now let's take rolling a prime number:
A prime number is a natural number greater than 1 which can only be divided without a remainder by 1 and itself. So from the numbers on the cube prime numbers are:
2, 3 and 5. The probability of getting a prime number in a single roll is:
P(B) =3/6=1/2
Now to calculate the probability of A and B
you have to multiply both probabilities:
P(A-B)=P(A) . P(B) = 1/3 . 1/2 = 1/6

What is the equation of the line that is parallel to y = 2/3x+ 4 and passes through
the point (-7, 1)?
Answer:
The answer is
[tex]y = \frac{2}{3} x + \frac{17}{3} [/tex]Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The original line is y = ⅔x + 4
Comparing with the general equation above
Slope = 2/3
Since the lines are parallel their slope are also the same
Slope of parallel line = 2/3
Equation of the line using point (-7 , 1) and slope 2/3 is
[tex]y - 1 = \frac{2}{3} (x + 7) \\ y - 1 = \frac{2}{3} x + \frac{14}{3} \\ y = \frac{2}{3} x + \frac{14}{3} + 1[/tex]
We have the final answer as
[tex]y = \frac{2}{3} x + \frac{17}{3} [/tex]Hope this helps you
