Find The Value Of XZY

Answers

Answer 1

Answer:

x = 40° , y = 43° , z = 97°

Step-by-step explanation:

∠ DAC = y = ∠ ACB = 43°

• opposite angles in a parallelogram are congruent , then

z = ∠ D = 97°

the sum of the 3 angles in Δ ACD = 180° , that is

x + y + 97° = 180°

x + 43° + 97° = 180°

x + 140° = 180° ( subtract 140° from both sides )

x = 40°

then

x = 40° , y = 43° , z = 97°

Analyzing Interest Rates
The Federal Reserve has control over the nation’s monetary policy. Through adjusting the required reserve ratio, buying and selling government bonds on the open market, or adjusting the discount rate, the Fed can influence interest rates and the money supply in the country. When we talk about interest rates, it’s important to distinguish between long-term and Short-term interest rates. Short-term interest rates are directly affected when the Fed changes its federal funds and discount rates and are for loans made for short periods. long-term interest rates are set by market forces. Lower long-term interest rates encourage investment by businesses and consumers because the cost of paying back the money over a long period is low.

The maximum total deduction that can be claimed is OE. $17,100.

What is deduction ?

Deduction refers to the process of subtracting or taking away something. In the context of taxes, a deduction is a specific amount of money that a taxpayer is allowed to subtract from their income before calculating their tax liability. Deductions are one way to reduce the amount of taxes owed and can help to lower a person's overall tax burden.

There are two main types of deductions in the U.S. tax system: standard deductions and itemized deductions. The standard deduction is a fixed amount that varies depending on the taxpayer's filing status, while itemized deductions are specific expenses that a taxpayer can deduct from their taxable income. Some common examples of itemized deductions include mortgage interest, charitable contributions, medical expenses, and state and local taxes.

It's important to note that not all deductions are available to all taxpayers, and there are specific rules and limits that apply to each type of deduction. It's also important to keep accurate records and documentation to support any deductions that are claimed on a tax return.

The maximum total deduction that can be claimed is OE. $17,100, because that is the sum of the deductible expenses and the standard deduction.

The question is asking for the maximum total deduction that can be claimed, given certain deductible expenses and a standard deduction.

The standard deduction for the tax year is $6,100, and the deductible expenses are $6,000 in mortgage interest and $5,000 in charitable contributions.

Since the deductible expenses ($6,000 + $5,000 = $11,000) are less than the standard deduction of $6,100, it makes sense to use the standard deduction instead of itemizing deductions.

Therefore, the maximum total deduction would be the sum of the deductible expenses and the standard deduction:

$11,000 + $6,100 = $17,100

So, the maximum total deduction that can be claimed is OE. $17,100.

A square pen is made using four posts on each side. How many posts were used?​

Answers

Answer:

Step-by-step explanation:

If a square pen is made using four posts on each side, then the total number of posts used can be found by multiplying the number of sides by the number of posts per side. Since there are four sides to a square, we can multiply 4 by 4 to get:

4 x 4 = 16

Therefore, 16 posts were used to make the square pen.

Answer: 12 posts

Explanation: there are 4 posts on each side, but some posts will overlap because there must be posts on the 4 corners.
So first do
4x4=16
Then you have to subtract the overlapping posts on the 4 corners, so
16-4=12

After a 27% decrease the value of a game card was now on sale for $34.00. What was the original price?

Answers

The original price of the game card was approximately $46.58.

What purpose does a game serve?

When the game can be effectively described by a numerical "characteristic function," such as v(S), which expresses how much any coalition S of players may win with certainty, regardless of the behaviour of the other players, then we can most readily determine the value of the game.

Let x represent the game card's initial cost. So 1 - 0.27 = 0.73, the price would be 0.73x after a 27% drop.

We are aware that 34.00 = 0.73x. We can divide both sides by 0.73 to find x:

x = 34.00 ÷ 0.73

x ≈ 46.58

Thus, the game card's initial cost was only about $46.58.

A lighthouse has a shadow that is 36 36 feet long. Zara is 4 4 feet tall, and has a shadow that is 3 3 feet long. The two triangles formed are similar because the angle to the sun is the same. Use this information to complete the statement about the lighthouse.

Answers

The height of the lighthouse is 48 feet.

To find the height of the lighthouse, we can use the concept of similar triangles. When two triangles are similar, it means that they have the same shape but different sizes. In this case, the two triangles are similar because they have the same angle to the sun. That is, the angle between the ground and the line from the top of the lighthouse to the sun is the same as the angle between the ground and the line from Zara to the sun.

This proportion is based on the fact that the two triangles are similar, so the corresponding sides are in proportion.

So, we have:

(height of lighthouse) / 36 feet = 4 feet / 3 feet

We can solve for the height of the lighthouse by cross-multiplying:

(height of lighthouse) = 36 feet × (4 feet / 3 feet)

A car was stopped at a red light. When the light turns green, the car reaches a speed of 47 miles per hour in 4 seconds. What is the acceleration, to 1 decimal place?
feet/s2.

Answers

Answer:

275.7 ft/s^2 appr.

Step-by-step explanation:

47mi*5280=248160 feet per hour.

4 seconds = 4/(60*60)=1/900 of an hour.

1/900*248160=275.7 feet/s^2 approx.

Answer:

The car's acceleration is 17.2 ft/s².

Step-by-step explanation:

First we need to do some unit conversions.

Unit Conversions

There is 60 seconds in 1 minute.

There is 60 minutes in 1 hour.

So therefore there is 3600 seconds in 1 hour.

There is 5280 feet in 1 mile.

Now we can create an expression convert mph to ft/s

Multiply the speed value in mph by [tex]\frac{5280}{3600}[/tex] to get the speed in ft/s

We can simplify [tex]\frac{5280}{3600}[/tex]  to [tex]\frac{22}{15}[/tex].

Multiply the speed value in mph by [tex]\frac{22}{15}[/tex] to get the speed in ft/s.

We are given a speed of 47 mph.

[tex]47*\frac{22}{15}=68.93[/tex]

Numerical Evaluation of Acceleration

Now we can solve for the acceleration.

The formula for acceleration is

[tex]a=\frac{v_f-v_i}{t}[/tex]

In this example we are given

[tex]v_f=68.93\\v_o=0\\t=4[/tex]

Substituting our values into the equation for acceleration yields

[tex]a=\frac{68.93-0}{4}[/tex]

Evaluate [tex]\frac{68.93-0}{4}[/tex]

[tex]a=17.23[/tex]

The equation for the graphed function is [tex]y=\frac{8\left(x-1\right)^2}{5\left(x-2\right)^2\left(x+2\right)}[/tex]

How to determine the equation for the function

From the question, we have the following parameters that can be used in our computation:

The graph

On the graph, we have the following asymptotes

x = -2 and x = 2

This means that the denominator of the function is

(x + 2) and (x - 2)²

(x - 2) is squared because the graph appears to turn (not intersect) at the zeros of x = 1 (close to x = 2)

So, we have

y = a/(x + 2)(x - 2)²

Where a is a real value

The zero is x = 1 with a multiplicity of 2 (because the curve turns at x = 1)

So, we have

y = a(x - 1)²/(x + 2)(x - 2)²

The y-intercept is (0, 0.2)

This means that

0.2 = a(0 - 1)²/(0 + 2)(0 - 2)²

So, we have

0.2 = a/8

Evaluate

a = 1.6

So, we have

a = 8/5

The function becomes

y = 8(x - 1)²/5(x + 2)(x - 2)²

Express properly

[tex]y=\frac{8\left(x-1\right)^2}{5\left(x-2\right)^2\left(x+2\right)}[/tex]

Measurement is the method of comparing the properties of a quantity or object using a standard quantity.

Measurement is important to determine the quantity of any object.

A same quantity can have more than one type of measurement which can be converted to each other.

Given,

Speed of the satellite in feet per second = 12700 feet per second (ft/s)

We have,

5280 feet = 1 mile

1 feet = 1/5280 mile

12700 feet = 12700/ 5280 miles

Also,

60 minute = 1 hour

1 minute = 1/60 hour

60 seconds = 1 minute = 1/60 hour

1 second = 1/3600 hour

12700 feet per second =  12700/ 5280 miles ÷ 1/3600 hour

To test the null hypothesis that the mean of the population is 3 against the alternative hypothesis, u <3 with a significance level of 0.05, we can use a one-tailed t-test since the sample size is small and the population standard deviation is unknown.

The formula for the t-test statistic is:

t = (x(bar) - μ) / (s / √n)

Where:

x(bar) = sample mean

μ = population mean (null hypothesis)

s = sample standard deviation

n = sample size

Given the sample of six measurements: 2, 3, -1.5, 1.2

First, we need to calculate the sample mean, sample standard deviation, and t-test statistic.

Sample mean (x(bar)) = (2 + 3 - 1.5 + 1.2) / 4 = 1.93

Sample standard deviation (s) = √[(∑(x - x(bar))^2) / (n - 1)]

= √[((2 - 1.93)^2 + (3 - 1.93)^2 + (-1.5 - 1.93)^2 + (1.2 - 1.93)^2 +  / (4 - 1)]

= 1.92

t-test statistic = (x(bar) - μ) / (s / √n)

= (1.93 - 3) / (1.92 / √5)

= -1.23 (rounded to two decimal places)

Answers

For the given insertion sort program the answer is (E) I, II, and III.

What is insertion sort?

Insertion sort is a simple sorting algorithm that works by repeatedly iterating through the elements of an array, or a list, and inserting each element into its proper position within the sorted portion of the array. The algorithm maintains a sorted sublist of elements, which starts as the first element of the array, and then iterates through the remaining unsorted elements one-by-one, comparing each element with the elements in the sorted sublist and moving them to the right until the correct position is found. In other words, insertion sort iteratively expands the sorted sublist by inserting each new element into its correct position, until the entire array is sorted. The time complexity of the insertion sort algorithm is O(n^2) in the worst-case scenario, where n is the number of elements in the array, but it can perform much better on small datasets or partially sorted arrays.

According to given conditions:

For the first question:

After the first pass of the outer loop, the array will be [2, 5, 4, 1, 3, 6]. After the second pass, the array will be [2, 4, 5, 1, 3, 6]. After the third pass, the array will be [1, 2, 4, 5, 3, 6]. Therefore, the answer is (C) [1, 2, 4, 5, 3, 6].

For the second question:

Statement 1 will execute 6 times because there are 6 elements in the array. Statement 2 will also execute 6 times because each element in the array will be moved to its correct position during the insertion sort. Therefore, the answer is (E) 6, 6.

For the third question:

To correctly separate the words in listofWords with commas and enclose them in braces, we need to iterate through the list and add each word to the result string followed by a comma (except for the last word) and a space. Then we need to remove the last comma and space and add the opening and closing braces. This can be achieved with the following expression and condition:

Expression: listofWords.get(k) + ", "

Condition: k != listofWords.size() - 1

Therefore, the answer is (A) expression: listofWords.get(k) + ", ", condition: k != listofWords.size() - 1.

For the fourth question:

To sort the integers in elements in descending order, we need to make two changes to the sort method:

I. Replace line 9 with: if (elements[k] > elements[index])

II. Replace lines 15-17 with:

Line 15: int temp = elements[index];

Line 16: elements[index] = elements[j];

Line 17: elements[j] = temp;

III. Replace line 3 with: for (int j = elements.length - 1; j > 0; j--) and replace line 7 with: for (int k = 0; k < j; k++)

Therefore, for the given insertion sort program the answer is (E) I, II, and III.

Write a program that takes three integers as input: low, high, and x. The program then outputs the number of multiples of x between low and high inclusive.

Answers

The program to find the divisible values gives the number of multiples of 2 between 3 and 8 inclusive is 3

To check if an integer is divisible by x, you could divide it by x and check if the remainder is 0.

If the remainder is 0, then the integer is divisible by x and therefore is a multiple of x.

We can use this concept to find the number of multiples of x between low and high inclusive.

If low is 3, high is 8, and x is 2, then we can check if each number between 3 and 8 is divisible by 2.

3 is not divisible by 2, so it is not a multiple of 2.

4, however, is divisible by 2, so it is a multiple of 2.

5 is not divisible by 2, so it is not a multiple of 2.

6, however, is divisible by 2, so it is a multiple of 2.

Then 7 is not divisible by 2, so it is not a multiple of 2. 8 is divisible by 2, so it is a multiple of 2.

Therefore, the number of multiples of 2 between 3 and 8 inclusive is 3 (4, 6, and 8).

What is the frequency of the function f(x)? f(x)=14cos(2x)+5 express the answer in fraction form. Enter your answer in the box.

Answers

The frequency of the function f(x) is 1/π.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable. In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

We need to find the frequency of given function;

f(x)=1/4 cos(2x)+5

To finding the period and then use the general relation frequency

frequency = 1/period

In the given function f(x)=1/4 cos(2x)+5 here, only the constant 2 which will multiply with x effects the period.

As we know that 2π is the period of cosx then the period of cos(2x) is

2x=2π

x=π

So, the period of cos(2x) is π

Now the frequency is F=1/π

Could someone help me with part A, please, thanks! :)

Answers

Answer:

a. The amount borrowed is $95,000. The annual interest rate is 5%. The number of payments per year is 12 (monthly payments). The loan term in years is 25, and the payment amount is $450.


b. The loan requires a total of 25 x 12 = 300 payments over the full term.


To calculate the total amount paid over the full term of the loan, we can use the formula for the present value of an annuity:


PV = PMT x [(1 - (1 + r)^-n) / r]


Where PV is the present value (the amount borrowed), PMT is the payment amount, r is the monthly interest rate (5% / 12 = 0.004167), and n is the total number of payments (300).


Plugging in the values, we get:PV = $95,000

PMT = $450

r = 0.004167

n = 300PV = $450 x [(1 - (1 + 0.004167)^-300) / 0.004167] = $144,781.92


Therefore, the total amount paid over the full term of the loan is $144,781.92.
