The quotient of z₁ by z₂ in trigonometric form is:
7/21 * (cos(584°) + i sin(584°))
To find the quotient of z₁ by z₂ in trigonometric form, we'll express both complex numbers in trigonometric form and then divide them.
Let's represent z₁ in trigonometric form as z₁ = r₁(cosθ₁ + isinθ₁), where r₁ is the magnitude of z₁ and θ₁ is the argument of z₁.
We have:
z₁ = 7(cos(577°) + i sin(577°))
Now, let's represent z₂ in trigonometric form as z₂ = r₂(cosθ₂ + isinθ₂), where r₂ is the magnitude of z₂ and θ₂ is the argument of z₂.
From the given information, we have:
z₂ = 21(cos(-7°) + i sin(-77°))
To find the quotient, we divide z₁ by z₂:
z₁ / z₂ = (r₁/r₂) * [cos(θ₁ - θ₂) + i sin(θ₁ - θ₂)]
Substituting the given values, we have:
z₁ / z₂ = (7/21) * [cos(577° - (-7°)) + i sin(577° - (-7°))]
= (7/21) * [cos(584°) + i sin(584°)]
The quotient of z₁ by z₂ in trigonometric form is:
7/21 * (cos(584°) + i sin(584°))
Option C, 21(cos(-7°) + i sin(-77°)), is not the correct answer as it does not represent the quotient of z₁ by z₂.

What is equation?An equation is a mathematical statement that shows that two expressions are equal. It consists of two parts: the left-hand side (LHS) and the right-hand side (RHS), separated by an equals sign (=). The equals sign indicates that the two expressions are equal, and the goal of solving the equation is to find the value of x that makes this statement true. Equations can be solved using various algebraic techniques, such as simplifying and rearranging the expressions, applying operations to both sides of the equation, and factoring or expanding expressions. Solving an equation involves finding the values of the variables that make the equation true.
Here,
Let the total sum of money be x.
Then, according to the given ratio, A's share is 2/9 of the total sum, so we have:
2/9 * x = 20000
Multiplying both sides by 9/2, we get:
x = 90000
Now, we can find the shares of B and C as follows:
B's share = 3/9 * 90000 = 30000
C's share = 4/9 * 90000 = 40000

Situation 3: the total amount of money charged monthly on credit cards to the number of credit cards owned does not represent a function.
In a function, each input (or x-value) should have a unique output (or y-value). However, in this situation, the total amount of money charged monthly on credit cards depends on the number of credit cards owned. It is possible to have different credit card numbers but still have the same total amount of money charged monthly.
For example, two people could own different numbers of credit cards but have the same monthly charges.
As a result, the definition of a function can be violated by having many outputs (monthly charges) for a single input (number of credit cards).

Melissa's chocolate bar is 77% cocoa. If the weight of the chocolate bar is 92 grams, how many grams of
cocoa does it contain? Round your answer to the nearest tenth.
Answer:
70.8
Step-by-step explanation:
77% is the same as 0.77 so
92 * 0.77 = 77% of 92
92 * 0.77 = 70.84
rounded to the nearest tenth
70.8
You can use the weight of the chocolate bar given and find its 77% to get the weight of cocoa used in it.
The weight of cocoa in the given chocolate bar is 70.80 grams.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
\(\frac{a}{100}\) × \(b\)
Since weight of cocoa = 77% percent of chocolate bar's weight which is 92 gram,
Thus,
\(weight\) \(of\) \(cocoa=\frac{77}{100}\) × \(92=68.08\) \(grams\)
Thus,
The weight of cocoa in the given chocolate bar is 70.80 grams.

It is known that 60% of customers will need additional maintenance on their vehicle when coming in for an oil change. A random sample of 48 customers is taken. What is the probability that more than 70% of customers in the sample will need additional maintenance
Answer:
the probability that more than 70% of customers in the sample will need additional maintenance is 0.0371
Step-by-step explanation:
From the information given:
we are to determine the probability that more than 70% of customers in the sample will need additional maintenance
In order to achieve that, let X be the random variable that follows a binomial distribution.
Then X \(\sim\) Bin(48, 0.6)
However 70% of 48 samples is
= 0.7 × 48 = 33.6 \(\simeq\) 34
Therefore, the required probability is:
= P(X> 34)
\(= \sum \limits ^{48}_{x=34} (^{48}_{x}) (0.6)^x(1 - 0.6)^{48-x}\)
\(= \dfrac{48!}{34!(48-34)!} (0.6)^{34} (0.4)^{48-34}\)
\(= 4.823206232 \times 10^{11} (0.60)^{34}(0.4)^{14}\)
= 0.03709524328

Alex decides to invest in the stock of company Z by purchasing 1,000 shares at $2.35 per share. After a short while, the stock rises to $2.68 per share, at which point Alex decides to sell, realizing a profit. As a result of the sale, Alex must pay his stockbroker a fee, calculated as 5% of the profit on the investment. Calculate Alex's pre-tax profit (i.e. Total profit on the investment minus the broker fees). Give your answer in dollars and cents.
Answer:
$313.50
Step-by-step explanation:
The stocks were worth $2.35 per share when Alex bought them. The stock rose to $2.68 per share. Subtract the two value to find the amount gained per share.
2.68 - 2.35 = 0.33
Alex gained $0.33 per stock. Multiply this number by 1000 since that is how many shares he has.
0.33 × 1000 = 330
Alex made $330 from stocks. He must now pay his stockbroker a fee of 5%. Take 5% of 330 and subtract it from 330.
5% = 0.05
330 × 0.05 = 16.5
330 - 16.5 = 313.5
Alex's pre-tax profit is $313.50.
what is the equation of the line that passes through point (-4,1) and has a slope of -3/2
The equation of the line passing through the point (-4, 1), and having a slope of m = -3/2 is 2y = -3x - 10.
What is equation of a line?The slope of the line and a point on the line can be used to create the equation of a line. To better comprehend how the equation for a line is formed, let's learn more about the line's slope and the necessary point on the line. The slope of the line, which can be stated as a numeric integer, fraction, or the tangent of the angle it forms with the positive x-axis, is the line's inclination with respect to the positive x-axis. The coordinate system's point with the x coordinate and the y coordinate is referred to as the point.
The equation of the line passing through the points (x1, y1), with a slope of m is given by the formula:
(y - y1) = m (x - x1)
Given that the point is (-4, 1) and the slope, m = -3/2.
Substituting the values we have:
(y - y1) = m (x - x1)
y - 1 = -3/2 (x - (-4))
2(y - 1) = -3(x+ 4)
2y - 2 = -3x - 12
2y = -3x - 10
Hence, the equation of the line passing through the point (-4, 1), and having a slope of m = -3/2 is 2y = -3x - 10.

Answer in complete sentences.
By assuming that the taxpayer has $100,000 as income on the completed Form 1040, the total tax that the employee is responsible for paying will be: $17,836.
What are tax bracket or income tiers?A tax bracket is a range of incomes that are subject to a specific income tax rate. Tax brackets are part of a progressive tax system, which means that the level of tax rates rises progressively as an individual's income rises. Low-income taxpayers are taxed at relatively low rates, while higher-income taxpayers are taxed at higher rates.
For example, in 2022, a single filer with taxable income of $100,000 will pay $17,836 in tax, or an average tax rate of 18%. But your marginal tax rate or tax bracket is actually 24%. Therefore, the total tax that the employee is responsible for paying equals to $17,836.

What is probability?
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.
The outcomes for each of the following events are:
(a) Event "X and Y": {C}
To satisfy both events X and Y, the letter selected must come before "D" (which includes the letters A, B, and C) and must be one of the letters in the word "CAGE" (which includes only the letter C). Therefore, the only outcome that satisfies both events X and Y is the letter C.
(b) Event "X or Y": {A, B, C, E, G}
The outcomes that satisfy event X are A, B, and C (since they come before "D"), and the outcomes that satisfy event Y are C, A, G, and E (since they are letters found in the word "CAGE"). Therefore, the outcomes that satisfy either event X or event Y are {A, B, C, E, G}.
(c) The complement of event X: {D, E, F, G}
The complement of event X is the set of outcomes that do not satisfy event X. The outcomes that do not satisfy event X are D, E, F, and G (since they come after or are equal to "D"). Therefore, the complement of event X is {D, E, F, G}.
