The four vertices of a rectangle drawn on a complex plane are defined by 1 + 4i, -2 + 4i, -2 – 3i, and 1 – 3i. The area of the rectangle is square units.
Answer:
The area of rectangle =21 sq units .
Step-by-step explanation:
Given the four vertices of rectangle are 1+4i,-2+4i, -2-3i and 1-3i.
Consider ABCD is a rectangle and its vertices are 1+4i,-2+4i,-2-3i and 1-3i.
First we find sides of rectangle
AB=vertices of B- vertices of A
AB= -2+4i-(1+4i)=-3
If complex number=a+biThen modulus=[tex]\sqrt{a^2+b^2}[/tex]Length of AB= [tex]\sqrt{(-3)^2}[/tex]=3 ( Because magnitude = length always positive )BC= Vertices of C - vertices of B
BC=-2-3i-(-2+4i)=-7i
Length of BC=[tex]\sqrt{(-7)^2}[/tex]=7 ( Magnitude always positive)
CD= vertices of D- vertices of C
CD= 1-3i-(-2-3i)=3
Length of CD= [tex]\sqrt{3^2}[/tex]=3 ( Magnitude always positive)
DA= vertices of A - vertices of D
DA= 1+4i-(1-3i) =7i
Length of DA= [tex]\sqrt{7^2}[/tex]=7 ( Magnitude always positive)
AB=CD and DA= BC
Length BC=7 units
Breadth AB=3 units
Area of the rectangle = [tex]length\times breadth[/tex]
Area of rectangle =[tex]AB\times BC[/tex]
Area of rectangle= [tex]3\times 7[/tex]=21 sq units .Victor Malala has a net income of $1240.00 per month. If he spends $150.00 on food, $244.00 on a car payment, $300.00 on rent, and $ 50.00 on savings, what percent of his net income can he spend on other things?

What are the different types of solutions that you can get when you solve a system of linear equations? Describe the graphs of these different types of systems.
Answer:
there are no solutions (lines do not intersect)there is one solution (lines intersect at one point)there are an infinite number of solutions (lines overlap—are the same line)Step-by-step explanation:
"A system of linear equations" covers a lot of territory. In Algebra 1, it usually means two linear equations in two unknowns. Each of those equations will graph as a line on a coordinate plane.
A solution is a point that satisfies all the equations. That is, it is a point that is on all the lines described by the system of equations.
The geometry of lines on a plane comes into play with regard to solutions.
The lines may be parallel, hence never intersect. (No points will be on all the lines.)The lines may intersect at one point.The lines may be the same line, overlapping, identical, coincident, consisting of all the same points, an infinite number.for triangle cab find the length of a Side a
Solve for r.
4r-9s=K
Final answer:
To solve for 'r' in the given equation, add 9s to both sides and then divide by 4, resulting in r = (9s + K) / 4.
Explanation:
To solve for r in the equation 4r - 9s = K, we need to isolate r on one side of the equation. Here's how we can do this:
Add 9s to both sides of the equation to get 4r = 9s + K.Divide both sides of the equation by 4 to solve for r, resulting in r = (9s + K) / 4.Now, we have r expressed in terms of s and K, which is the desired form.Q9 Q11.) Complete the first and second equations of the system of equations.
Which quadratic equation equation is equivalent to (x^2-1)^2 -11(^2-1) +24=0
Answer:
x = ± 3 and ± 2
Step-by-step explanation:
The given quadratic equation is
[tex](x^{2}-1)^{2}-11(x^{2}-1)+24=0[/tex]
To make this question easier we will consume ( x² -1 ) = a
a² - 11a + 24 = 0
Now we can factorize this equation easily
a²- 8a - 3a + 24 = 0
a (a-8) - 3 ( a-8) = 0
( a-3 ) ( a-8 ) = 0
Therefore, a - 3 = 0 ⇒ a = 3
or a - 8 = 0 ⇒ a = 8
Now we put the value a
when a = 3 (x² - 1) = 3
x² = 3 + 1 = 4
x = √4
= ± 2
when a = 8 (x² - 1) = 8
x² = 9
x = √9
= ± 3
Therefore, x = ± 3 and ± 2 will be the answer.

Answer:

Step-by-step explanation:
A person in a balloon which is 2,000 feet above the airport finds that the angle of depression to a ship out at sea is 21°. Find the horizontal distance between the balloon and the ship.
The horizontal distance between the balloon and the ship can be calculated using the tangent function is 1639 feet.
To find the horizontal distance between the balloon and the ship, we can use the tangent function in trigonometry. Let's denote the horizontal distance as x, and the distance between the balloon and the ship along the ground as y.
We have the angle of depression (21°) and the altitude of the balloon (2,000 feet). We can set up the equation:
tan(21°) = y / (2,000 + y)
Now, we need to solve for y:
tan(21°) * (2,000 + y) = y
y * tan(21°) = 2,000 * tan(21°) - y * tan(21°)
y * (1 - tan(21°)) = 2,000 * tan(21°)
y = (2,000 * tan(21°)) / (1 - tan(21°))
Now, calculate the value:
y ≈ (2,000 * 0.364) / (1 - 0.364)
y ≈ 728 / 0.636
y ≈ 1,148.17
Now that we have the value of y, we can find the horizontal distance x using the Pythagorean theorem:
[tex]x^2 + y^2 = (2,000)^2\\x^2 + (1,148.17)^2 = 4,000,000\\x^2 = 4,000,000 - 1,319,441.98\\x^2 = 2,680,558.02\\x = 1,638.84 (rounded)[/tex]
The horizontal distance between the balloon and the ship is approximately 1,639 feet.
Horizontal distance = height of balloon / tangent(angle of depression) = 2000 / tan(21°) ≈ 5243.87 feet.
To find the horizontal distance between the balloon and the ship, we can use trigonometry, specifically the tangent function.
Let's denote:
- [tex]\( h \)[/tex] as the height of the balloon above the ground (2,000 feet in this case).
- [tex]\( \theta \)[/tex] as the angle of depression (the angle formed between the line of sight from the balloon to the ship and the horizontal ground).
Given that the angle of depression [tex]\( \theta \)[/tex] is 21°, we can use the tangent function:
[tex]\[ \tan(\theta) = \frac{\text{opposite}}{\text{adjacent}} \][/tex]
In this case, the opposite side is the height of the balloon above the ground (2,000 feet), and we want to find the adjacent side, which represents the horizontal distance between the balloon and the ship.
So, we have:
[tex]\[ \tan(21°) = \frac{2000}{\text{horizontal distance}} \][/tex]
To find the horizontal distance, we rearrange the equation:
[tex]\[ \text{horizontal distance} = \frac{2000}{\tan(21°)} \][/tex]
Now, we can calculate this:
[tex]\[ \text{horizontal distance} = \frac{2000}{\tan(21°)} \approx \frac{2000}{0.381} \approx 5243.87 \text{ feet} \][/tex]
So, the horizontal distance between the balloon and the ship is approximately 5243.87 feet.

Jewelry is commonly weight in carats.Five carats are equivalent to one gram.How many grams of gold are contained in 24-carat gold chain
Suppose we calculate a 95% confidence interval for the population mean to be (6.93, 11.45). how do we interpret this?
The [tex]95\%[/tex] confidence interval for the population mean is [tex]\left( {6.93,11.45}\right)[/tex] means that there are [tex]95\%[/tex] chances of the population mean lies in the interval.
Further Explanation:
Explanation:
The formula for confidence interval can be expressed as follows,
[tex]\boxed{{\text{Confidence interval}}=\left( {\overline X \pm ME} \right)}[/tex]
ME represents the Margin of Error.
The confidence interval has two limits.
(1). Upper Limit
(2). Lower Limit
The upper limit can be calculated as follows,
[tex]{\text{Upper limit}}=\left( {X + ME}\right)[/tex]
The lower limit can be calculated as follows,
[tex]{\text{Lower limit}} = \left( {X - ME}\right)[/tex]
The given confidence interval is [tex]\left( {6.93,11.45}\right).[/tex]
The upper limit of the confidence interval is 11.45.
The lower limit of the confidence interval is 6.93.
The 95\% confidence interval for the population mean is [tex]\left( {6.93,11.45}\right)[/tex] means that there are [tex]95\%[/tex] chances of the population mean lies in the interval.

What is the inverse function of f(x)=5x-3
The inverse function of f(x) = 5x - 3 is found by switching x and y to solve for x, resulting in the inverse function f⁻¹(x) = (x + 3) / 5. This process is part of understanding function transformations that change a function's graph.
Finding the Inverse Function
Find the inverse function of f(x) = 5x - 3. To find the inverse, we need to switch the roles of x and y. So we first write y = 5x - 3. We then solve this equation for x to get x as a function of y. Performing the steps:
Add 3 to both sides: y + 3 = 5x.
Divide both sides by 5: (y + 3) / 5 = x.
This new equation x = (y + 3) / 5 represents the inverse function. To use the proper notation, we replace y with f⁻¹(x) and x with y, giving us f⁻¹(x) = (x + 3) / 5.
Understanding Function Transformations
When considering transformations such as f(-x) or f(2x), these changes to the independent variable result in specific alterations to the graph of the function, such as reflections across the y-axis or horizontal shrinkage by half.
