Assumptions for above case:
1-Equal payments are made monthly.
2-Total amount deposited throughout the year are compounded by end of the year.
3-Annual interest is 6%
4-Total Amount invested plus interest at maturity are reinvested the following year.
Given above, if you create a table in excel for those calculations, you would get $296.330 /month which amounts to $12,000.00 in 3 years approximately.
Year 1 = $3,555.96 Pre-interest =>$3769.32 Post 6% interest
Year 2 = $7,325.28 Pre-interest =>$7,325.28 Post 6% interest
Year 3= $11,320.75 Pre-interest =>$12,000.00 Post 6% interest.
The way to calculate pre interest for each year is just $296.330*12=$3555.96
Afterwards just multiply by the annual interest rate to get the full amount invested + interest (6%) =>$3555.96*(1.06)= $3769.32
Then As per step 1, add another 3555.96 and multiply it all by 1.06, to get 305.06

Peyton drew a right triangle with sides 5
cm, 12
cm, and 13
cm long. Carter drew a similar triangle to Peyton’s. Which of the following can be the measurements of Carter’s triangle?
Option B. The length of the hypotenuse of Carter's triangle is 13cm.
Since Carter's triangle is similar to Peyton's triangle, the ratio of corresponding side lengths will be the same. Let's use x to represent the length of the hypotenuse of Carter's triangle.
We know that the ratio of the lengths of the hypotenuse and the shorter leg of Peyton's triangle is 13:5. So, the ratio of the lengths of the hypotenuse and the shorter leg of Carter's triangle must also be 13:5.
Thus, we have x/5 = 13/5, which simplifies to x = 13.
Therefore, the length of the hypotenuse of Carter's triangle is 13cm.
Therefore, the only possible length for Carter's hypotenuse is 13cm, and the correct answer is A.

Check the picture below.
A point R (-5, 6) is reflected across X axis to obtain point S, write the coordinates of S.
A company finds that if it charges 2 dollars for a cell phone, it can expect to sell 1,000 - 2x phones. The company uses the function
defined by r(x)=(1,000-2x) to model the expected revenue, in dollars, from selling cell phones at a dollars each.
1. Use graphing technology to graph the function r.
2. What do the z-intercepts mean in this situation?
3. Is 0≤x≤ 600 an appropriate domain for the function 7? Explain your reasoning.
4. At what price should the company sell their phones to get the maximum revenue? Explain your reasoning.
The z-intercept is at 500, the domain of the function is all non-negative real numbers, or [0, ∞) and the maximum revenue is 500
What does the z-intercepts interpret in this situation?1. The graph of the function is attached below;
2. The z-intercept is where the graph intersects the x-axis, which occurs when the revenue is 0. In this situation, the z-intercept represents the maximum price that the company can charge for the cell phone and still expect to sell some units. So, the z-intercept is $500, meaning if the company charges more than $500, it will not sell any cell phones and its revenue will be 0.
3. No, 0≤x≤ 600 is not an appropriate domain for the function. The company can charge any price, not just prices between 0 and 600 dollars. The domain of the function should be all non-negative real numbers, or [0, ∞).
4. The maximum revenue occurs at the point where the slope of the function changes from negative to positive, which is the vertex of the parabola. In this case, the function r(x) is a linear function, so there is no vertex. The maximum revenue occurs at the endpoint of the domain, which is x=500, since the company cannot charge more than $500 without reducing the number of phones sold to 0. Therefore, the company should charge $500 to get the maximum revenue.

What is a triangle's definition?
A triangle is a geometric form that has three straight sides and three angles. It is a fundamental geometric form that is frequently utilised in mathematics, science, and everyday life.
Triangles are distinguished by three sides and three angles. The sum of each triangle's three angles is always 180 degrees. Triangles are classified according to the length of their sides and the measurement of their angles.
Now,
As given ΔDEF ≈ΔABC
that means ratio of all sides will be equal
i.e. AB/DE=BC/EF=AC/DF
then AB/8.8=6.71/6.1
AB=1.1*8.8
AB=9.68
and BC/6.4=6.71/6.1
BC=1.1*6.4
BC=7.04
Hence,
the values of AB and BC are 9.68 and 7.04 respectively.

Draw the image of traingel ABC under a dilation whose center is p and scale factor is 1/2
A graph of the image of ABC under a dilation whose center is P and scale factor is 1/2 is shown in the image below.
What is dilation?In Geometry, a dilation can be defined as a type of transformation which typically changes the size of a geometric shape, but not its shape.
In this exercise, we would use an online graphing calculator to plot the image of ABC after a dilation by a scale factor of 1/2 centered at P.
Based on the image (see attachment), we can logically deduce that each vertex is 1/2 times as far from center P as the original vertex and each segment is 1/2 times as long as the original:
Side length A'C' = 8.2/2 = 4.1
Side length A'B' = 5.7/2 = 2.85
Side length B'C' = 12.2/3 = 6.1

The probability that more than 35 students are women in a random sample of 55 university students is 0.256.
What is binomial distribution?The binomial distribution is a probability distribution that expresses the number of successes in a finite number of independent trials when the chance of success is constant and there are only two potential results (success or failure). Since a known chance of success for each trial is known, we may use it to determine the likelihood of a certain number of successes (or failures) in a set number of trials.
Given that p = 60% = 0.6, n = 55.
Using normal approximation we have:
SD = sqrt(np(1-p))
= sqrt(55 x 0.60 x 0.40) = 3.05
The z-score is:
z = (X - np) / SD)
z = (35 - (0.4)(0.6)) / 3.05
z = 11.39 = 0.256.

The initial population of a bacterial culture is 2000, growing at a fixed rate. Table shows the population every hour for six hours.
A. Find the equation that models this relation. (round to one decimal place).
B. Use the equation to find the population of bacteria after 12 hours after 24 hours.
Answer: A. To find the equation that models this relation, we can plot the data and look for a trend.
From the graph, we can see that the data follows an exponential growth pattern. The equation for exponential growth is:
y = ab^x
where y is the final population, a is the initial population, b is the growth rate, and x is the time in hours.
Using the data from the table, we can find the value of b:
b = y/x
where y is the population after x hours.
For example, after 2 hours, the population is 5000:
b = 5000/2 = 2500
We can repeat this process for each time period and find the average value of b:
b = (2500 + 3125 + 3906.25 + 4882.81 + 6103.51 + 7629.38) / 6 = 4275.5
Now that we have the value of b, we can find the equation that models the relation:
y = 2000(4275.5)^x
Rounding to one decimal place:
y = 2000(4.3)^x
B. Using the equation, we can find the population after 12 and 24 hours:
y = 2000(4.3)^12 ≈ 8,898,335.7
y = 2000(4.3)^24 ≈ 7.42 x 10^13

Where are the vertices of triangle A’B’C’ located? Show your work or explain your steps. (4points)
The vertices of ∆A′B′C′ are A′(-6, 5), B′(-6, 8), and C′(-10, 5) upon the application of the translation rule.
What is the translation rule in geometry?
In geometry, a translation is a transformation that moves every point of a figure the same distance in the same direction. In the case of a triangle, a translation rule describes how to move each vertex of the triangle to a new location to create a new triangle with the same size and shape, but in a different position.
A translation rule for a triangle is given by a pair of numbers (a, b), which indicate the amount of horizontal and vertical movement of the vertices. Specifically, the rule is given by the formula:
(x, y) → (x + a, y + b)
This formula means that we move every point in the triangle a unit to the right or left (depending on the sign of a) and b units up or down (depending on the sign of b).
The translation rule (x, y) → (x − 3, y + 4) means that we move every point in the original triangle left by 3 units and up by 4 units. So, the translation is described as a leftward shift of 3 units and an upward shift of 4 units.
To find the vertices of ∆A′B′C′, we apply the translation rule to each vertex of ∆ABC:
Vertex A: (x, y) → (x - 3, y + 4)
(-3, 1) → (-3 - 3, 1 + 4) = (-6, 5)
So, vertex A of ∆A′B′C′ is located at (-6, 5).
Vertex B: (x, y) → (x - 3, y + 4)
(-3, 4) → (-3 - 3, 4 + 4) = (-6, 8)
So, vertex B of ∆A′B′C′ is located at (-6, 8).
Vertex C: (x, y) → (x - 3, y + 4)
(-7, 1) → (-7 - 3, 1 + 4) = (-10, 5)
So, vertex C of ∆A′B′C′ is located at (-10, 5).

The term "exponential decay" in mathematics refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)x, where x is the amount of time that has passed, an is the initial amount, b is the decay factor, and y is the final amount.
To find the annual rate of change between 1992 and 2006, we can use the formula:
r = [tex](V_2/V_1)^{1/n}-1[/tex]
where V1 is the initial value, V2 is the final value, and n is the number of years between the two values.
=>r = -0.0839
Therefore, the rate of change between 1992 and 2006 is -0.0839.
To express the rate of change in percentage form, we can multiply the result from part A by 100:
=>r = -0.0839 x 100
=> r = -8.39%
Therefore, the rate of change between 1992 and 2006 is a decrease of 8.39%.
To find the value of the car in the year 2009, we can assume that the value continues to drop at the same percentage rate as calculated in part A.
From 2006 to 2009, there are 3 years. So, using the formula for exponential decay, we have:
where V0 is the value in 2006, r is the rate of decrease, and n is the number of years between 2006 and 2009.
=>V = 11792.51
Therefore, the value of the car in the year 2009 would be approximately $11,800 (rounded to the nearest $50).

khaled plants to go to the animal shelter to adopt a cat and then take it to the grooming shop. the shelter is located at (-3,-5) and the grooming shop is located at (5,-1). find the location of lhaled house if the distance from his house to the shelter and the distance from his house to the grooming shop has a ratio of 1:3
After answering the presented question, we can conclude that coordinates Therefore, Khaled's house is located at approximately (-4.75, -1.5).
what are coordinate ?In mathematics, a coordinate is a number or combination of numbers that represents the location of a point or object in space. Coordinates are frequently used to define a point or object's position in a certain coordinate system, such as the Cartesian or polar coordinate systems. In the Cartesian coordinate system, a point is found by its distance from the origin along the x-axis and its distance from the origin along the y-axis. These distances are represented by two integers, the x-coordinate and the y-coordinate. The point's location in the plane is specified by the two coordinates.
Distance from Khaled's house to the animal shelter:
[tex]d_1 = \sqrt((x - (-3))^2 + (y - (-5))^2) = \sqrt((x + 3)^2 + (y + 5)^2)[/tex]
Distance from Khaled's house to the grooming shop:
[tex]d_2 = \sqrt((x - 5)^2 + (y - (-1))^2) = \sqrt((x - 5)^2 + (y + 1)^2)\\d_1/d_2 = 1/3\\\sqrt((x + 3)^2 + (y + 5)^2) / \sqrt((x - 5)^2 + (y + 1)^2) = 1/3\\((x + 3)^2 + (y + 5)^2) / ((x - 5)^2 + (y + 1)^2) = 1/9\\8x + 38y + 4 = 0\\[/tex]
So the coordinates of Khaled's house are:
x = -4.75
y = -1.5
Therefore, Khaled's house is located at approximately (-4.75, -1.5).

A real estate broker decides to lease a car for 36 months. Suppose the anual interest rate is 7.8%, the negotiated price is $49,000, there is no trade-in, and the down payment is $4,000. Find the monthly lease payment (in dollars). Assume that the residual value is 49% of the MSRP of $51,500. (Round your answer to the nearest cent.)
Answer:
To find the monthly lease payment, we need to use the formula:
Monthly lease payment = (Net capitalized cost - Residual value) / Lease term in months
where:
Net capitalized cost = negotiated price - down payment
Residual value = percentage of MSRP x MSRP
Lease term in months = 36
First, we need to calculate the net capitalized cost:
Net capitalized cost = $49,000 - $4,000 = $45,000
Next, we need to calculate the residual value:
Residual value = 49% x $51,500 = $25,235
Now we can plug in the values and solve for the monthly lease payment:
Monthly lease payment = ($45,000 - $25,235) / 36 = $548.76
Therefore, the monthly lease payment is approximately $548.76.
Find the extract value of x
Answer:
25 + 5√29
Step-by-step explanation:
(I added a photo below)
First, let's find BC using the Pythagorean theorem (from ∆BCD):
[tex] {bc}^{2} = {25}^{2} + {10}^{2} = 625 + 100 = 725[/tex]
[tex]725 > 0[/tex]
[tex]bc = \sqrt{725} =5 \sqrt{29} [/tex]
Then we see, that AB = 25 + x
So, now we can find AC:
[tex] {ac}^{2} = ({25 - x})^{2} - ({5 \sqrt{29} })^{2} = 625 - 50x + {x}^{2} - 25 \times 29 = 625 - 50x + {x}^{2} - 725 [/tex]
Now we have a quadratic equation:
[tex] {x}^{2} - 50x - 100 = 0[/tex]
[tex]d = {b}^{2} - 4 \times a \times c = ({ - 50})^{2} - 4 \times 1 \times ( - 100) = 2500 + 400 = 2900 > 0[/tex]
[tex]x1 = \frac{ - b - \sqrt{d} }{2a} = \frac{50 - 10 \sqrt{29} }{2} = 25 - 5 \sqrt{29} [/tex]
This is a negative number and we cannot use it, since x has to be a natural number
[tex]x2 = \frac{ - b + \sqrt{d} }{2 a} = \frac{50 + 5 \sqrt{29} }{2} = 25 + 5 \sqrt{29} [/tex]
