If Z₁=3-2i
Z2=-2+3i
Z3=4+2i
Evaluate Z₂ Z3/Z₁
Answer:
32/13
Step-by-step explanation:
To evaluate the expression Z₂ * Z3 / Z₁, we first need to find the complex numbers Z₂ * Z3 and Z₁.
Z₂ * Z3 = -2 + 3i * 4 + 2i = (-8 + 14i) + (-6 + 6i) = -8 + 8i
Z₁ = 3 - 2i
So, Z₂ * Z3 / Z₁ = (-8 + 8i) / (3 - 2i)
We can simplify this expression by multiplying the numerator and denominator by the complex conjugate of the denominator, which is (3 + 2i).
Z₂ * Z3 / Z₁ = (-8 + 8i) / (3 - 2i) * (3 + 2i) / (3 + 2i) = (-8 + 8i) * (3 + 2i) / (3 - 2i) * (3 + 2i)
Z₂ * Z3 / Z₁ = ((-8 * 3 + 8 * 2i) + (8 * 3 + 8 * 2i)) / (3^2 + (-2i)^2) = (16 + 16i) / 13
Therefore, Z₂ * Z3 / Z₁ = (16 + 16i) / 13.
Each worker at a store gets paid $15.90 for that first 40 hours worked. After 40 hours, they earn time and a half wages. Every employee has a 28% of his/her gross pay deducted for taxes, insurance etc. how much of a net pay does each worker take home?
Each worker would take home a net pay of $586.71.
What is the net pay?
The net pay is the amount of money that an employee takes home after all deductions have been made from their gross pay. Gross pay is the total amount of money an employee earns before taxes and other deductions are taken out.
To calculate net pay, you need to subtract all the required deductions from the employee's gross pay.
To calculate the net pay for each worker, we first need to determine their gross pay. The gross pay will depend on the number of hours they worked and whether they worked any overtime.
For the first 40 hours worked, each worker earns $15.90 per hour, so their gross pay for those hours would be:
Gross Pay for 40 hours = $15.90/hour x 40 hours = $636
For any hours worked beyond 40, the worker earns time and a half wages. This means they earn 1.5 times their regular hourly wage of $15.90, or $23.85 per hour. So, if they worked, for example, 45 hours in total, the additional 5 hours would be paid at the overtime rate, resulting in an additional gross pay of:
Gross Pay for 5 overtime hours = $23.85/hour x 1.5 x 5 hours = $178.88
Therefore, their total gross pay would be:
Total Gross Pay = Gross Pay for 40 hours + Gross Pay for 5 overtime hours = $636 + $178.88 = $814.88
Now, we need to calculate the deductions, which we are told are 28% of the gross pay. So the total deductions would be:
Total Deductions = 28% x $814.88 = $228.17
Finally, to determine the net pay, we need to subtract the total deductions from the gross pay:
Net Pay = Gross Pay - Total Deductions = $814.88 - $228.17 = $586.71
Therefore, each worker would take home a net pay of $586.71.

The discount on each orange is 81.3%
What is discount?The discount equals the difference between the price paid for and it's par value. Discount is a kind of reduction or deduction in the cost price of a product.
A sales discount is a reduced price offered by a business on a product or service.
The total price for the oranges is;
0.75 × 7 = $5.25
She paid $ 4.30 for the oranges, this means that the discount = 5.25-4.30 = $0.95
Therefore the percentage discount on all the oranges = 0.95/5.25 × 100
= 18.1%
by discount each orange = 4.30/7 =$ 0.61
Therefore the discount on each orange = 0.61/0.75 ×100 = 81.3 %

The transformations taking place in the given function is a horizontal left ward shift of 9 units and 1 unit upward vertical shift.
What is transformation?A Transformation in Math is a process of moving an object (two-dimensional shape) from its original position to a new position.
Given that, a function f(x) undergo some transformations to become f(x+9)-1,
We know that,
Vertical Shifting:
Adding a constant to a function will shift its graph vertically (i.e. y = f (x) + c). Adding a positive constant c will shift the graph upward c units, while adding a negative constant c will shift it downward c units.
Horizontal Shifting:
Horizontal shifts are inside changes that affect the input (x-) axis values and shift the function left or right. Combining the two types of shifts will cause the graph of a function to shift up or down and right or left.
Therefore, there is transformation of a horizontal and vertical shift.

A) In a geometric sequence, t_(1)=625 and the common ratio is r=(1)/(5). For what value of n is t_(n)=(1)/(25)?
b) Determine whether each sequence is arithmetic, geometric, or neither. Then find a formula for the n-th term of the sequence.
(2)/(5),(3)/(6),(4)/(7),(5)/(8),dots
Answer:
Step-by-step explanation:
A) In a geometric sequence, t_(1)=625 and the common ratio is r=(1)/(5). For what value of n is t_(n)=(1)/(25)?
Step 1: Write the formula for the nth term
The formula for the nth term of a geometric sequence is t_n = t_1 * r^(n-1), where t_1 is the first term and r is the common ratio.
Step 2: Substitute the given values into the formula
t_n = 625 * (1/5)^(n-1)
Step 3: Solve for n when t_n = (1/25)
(1/25) = 625 * (1/5)^(n-1)
(1/25) / 625 = (1/5)^(n-1)
(1/5)^(n-1) = (1/25) / 625
(n-1) = log base (1/5) of ((1/25) / 625)
Step 4: Solve for n
n = 1 + log base (1/5) of ((1/25) / 625)
The value of n is the number of terms that have passed when t_n = (1/25).
B) (2)/(5),(3)/(6),(4)/(7),(5)/(8),...
Step 1: Determine the type of sequence
A sequence is an arithmetic sequence if the difference between any two consecutive terms is constant. Since this sequence does not have a constant difference, it is not an arithmetic sequence.
A sequence is a geometric sequence if the ratio between any two consecutive terms is constant. We can see that the ratio between any two consecutive terms is constant, so this sequence is a geometric sequence.
Step 2: Find the common ratio
To find the common ratio, we can divide any two consecutive terms. For example, the common ratio is (3/6) / (2/5) = (3/2) / (6/5) = 5/6.
Step 3: Write the formula for the nth term
The formula for the nth term of a geometric sequence is t_n = t_1 * r^(n-1), where t_1 is the first term and r is the common ratio.
Step 4: Substitute the given values into the formula
To use this formula, we need to know the value of t_1. We are given t_1 = (2/5), so:
t_n = (2/5) * (5/6)^(n-1)
This is the formula for the nth term of the sequence (2)/(5),(3)/(6),(4)/(7),(5)/(8),...

How to find their ages?Word problems are sentences describing a 'real-life' situation where a problem needs to be solved by way of a mathematical calculation.
Let L and Y represent the age of the older person and younger person respectively.
Using the given information, we can write:
L = 4Y + 5 --- (1)

L = 30 - Y --- (3)
Put (3) in (1):
L = 4Y + 5
30 - Y = 4Y + 5
4Y + Y = 30 - 5
5Y = 25
Y = 25/5
Y = 5 years
Put Y = 5 into (3):
L = 30 - Y
L = 30 - 5
L = 25 years

A spotlight is fixed on the ground 35m from the town hall. It is switched on at night to illuminate the building. When Dirk stands 5m in front of the light, his shadow is as tall as the building, If Dirk is 1.40m tall, how tall is the town hall?
To answer this question, we need to use some basic trigonometry. We know that Dirk's shadow is as tall as the town hall and that Dirk is 1.40m tall. So, if we can determine the angle of elevation of the spotlight, we can calculate the height of the town hall.
Let's call the angle of elevation "α" and the distance from the spotlight to the town hall "d". To determine α, we can use the tangent function.
tan α = opposite/adjacent = (d-5)/35 = (30/35) = 0.8571
The angle of elevation is arctan(0.8571) = 53.13°.
Now, we can use the sine function to calculate the height of the town hall:
sin α = opposite/hypotenuse = 1.4/d
d = 1.4/sin 53.13° = 16.2m
Therefore, the town hall is 16.2m tall.

The probability distribution does not add up to 1.0, in other words.
What is meant by probability?Probability, in its simplest form, gauges the likelihood that something will happen. When we are unsure of how an event will turn out, we might talk about the likelihood of different outcomes.The study of events susceptible to probability is known as statistics. The probability is frequently stated as a ratio between the total number of outcomes in the sample space and the number of positive outcomes.This is how it is written: Number of Favorable Outcomes P(E) = Probability of an Event (Sample space).Probability can be divided into four main categories: axiomatic, axiomatic, classical, and empirical. The area of mathematics known as probability studies the likelihood that a random event will occur.The complete question is:
A researcher records the number of mistakes made during a memory skills task. He finds that the probability that participants in this study made 0 mistakes is p = .22; made 1 mistake is p = .30; made 2 mistakes is p = .16; made 3 mistakes is p = .12; and made 4 or more mistakes is p = .25.

Answer:
It is not accurate
Step-by-step explanation:
If the complete question is:
A researcher records the number of mistakes made during a memory skills task. He finds that the probability that participants in this study made 0 mistakes is p = .22; made 1 mistake is p = .30; made 2 mistakes is p = .16; made 3 mistakes is p = .12; and made 4 or more mistakes is p = .25. Is this probability distribution accurate?
THEN:
To determine whether the probability distribution is accurate, we need to check two conditions:
The sum of the probabilities should be equal to 1.
All probabilities should be between 0 and 1.
Let's check these conditions:
Sum of probabilities:
p(0) + p(1) + p(2) + p(3) + p(4 or more) = 0.22 + 0.30 + 0.16 + 0.12 + 0.25 = 1.05
The sum of the probabilities is greater than 1, which violates the first condition. Therefore, this is not a valid probability distribution.
All probabilities should be between 0 and 1:
The probability of making 0, 1, 2, or 3 mistakes are all between 0 and 1, so they satisfy this condition.
However, the probability of making 4 or more mistakes is 0.25, which is a valid probability, but it implies that the probability of making 0, 1, 2, or 3 mistakes is negative, which is impossible. Therefore, this distribution does not satisfy this condition.
Since this probability distribution violates both conditions for a valid probability distribution, it is not accurate, and the researcher should revise their data.

How to find the area of a region?Supposing that there is no direct formula available for deriving the area, we can derive the area of that region by dividing it into smaller pieces, whose area can be known directly. Then summing all those pieces' area gives us the area of the main big region.
We know that the perimeter is the total length of all the sides. The length of the horizontal sides is; 8 ft + 10 ft = 18 ft.
The length of the slant sides can be found by the Pythagorean theorem.
For side length s, we have;
s^2 = 8^2 + 16^2
s^2 = 64 +256 = 320
s = √320 = 8√5

To find the percentage of trials where Mansour scored exactly one penalty, we have to count the trials where one of the simulated numbers is in the range of 1 to 5 (denoting Mansour scoring the penalty) and the other is in the range of 56 to 100 (denoting Mansour missing the penalty)
Trails 1, 3, and 4, 6 are such trials. Thus, Mansour scored exactly one penalty kick in 40% of the trials.

A crew of construction workers are disassembling the inside of a building and dropping things into dumpsters at the base of the building. The equation Va=(64d)122
is used to find the average velocity, or speed, in feet per second of an object that has fallen a distance of d feet. What is the average velocity, to the nearest hundredth, of a ceiling tile that fell 43 feet ?
The average velocity, to the nearest hundredth, of a ceiling tile that fell 43 feet is 344 feet per second
What is speed?Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is travelling along a route.
Given that the formula for the speed of a falling object is v= √64d,
where v is the speed of the object in feet per second and d is the distance the object has fallen, in feet.
And also given that d = 43 feet.
Substituting the value to the formula,
v = √64 (43)
v = 8 x 43
v = 344
Therefore, 344 feet per second is the velocity.

Samir made a scale drawing of a city. He used the scale 5 inches = 1 yard. What scale factor
does the drawing use?
Simplify your answer and write it as a fraction.
Answer:
the scale factor that Samir used in his drawing is 5/1.
Step-by-step explanation:
Here's a step by step explanation of how to find the scale factor of a drawing:
Identify the scale used in the drawing. In this case, the scale used in Samir's drawing is 5 inches = 1 yard.
Express the scale as a ratio between the two sizes. In this case, the ratio is 5 inches : 1 yard.
Simplify the ratio, if possible. In this case, the ratio 5 inches : 1 yard can be simplified to 5/1.
The simplified ratio, 5/1, is the scale factor of the drawing. This means that for every 5 inches on the drawing, the actual length in the real world is 1 yard.
So, the scale factor that Samir used in his drawing is 5/1.
3. Juanita put $2,000 in a 6-month CD. The interest rate is 3%. The interest is compounded quarterly. What is the interest for the first quarter? What will be the value of the CD when it matures?
The interest for the first quarter would be $ 15
The value of the CD when it matures is $ 2, 030. 11
How to find the value of the CD ?The interest is said to compound quarterly which means that the periodic interest rate per quarter is:
= 3 % / 4
= 0. 75 % per quarter
The interest in the first quarter :
= 0. 75 % x 2, 000
= $ 15
The value of the CD at maturity is:
= 2, 000 x ( 1 + 0. 75% ) ²
= $ 2, 030. 11
Note : 2 periods because 6 months is 2 quarters.

What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
y = 5.8 + 2.5x
This is in the form of y = mx + c
So,
m = 2.5
And,
The y-intercept is when x = 0.
So,
y = 5.8 + 2.5x
Substitute x = 0,
y = 5.8
Thus,
Slope is 2.5
The y-intercept is 5.8.
