Answer:

5d+4

Step-by-step explanation:

Number of ticket sold by Daniel = d .... 1

If Sara sold 4 more tickets to the school play than the number Danielle sold, the total number sold by Sarah is expressed as d+4 .... 2

If Brett sold 3 times as many as Danielle sold, the amount sold by Brett is 3×d = 3d ..... 3

The number of tickets that the 3 students sold altogether can be gotten by adding equation 1, 2 and 3 together as shown;

d+(d+4)+3d

Collect like terms

= d+d+3d+4

= 2d+3d+4

= 5d+4

Step-by-step explanation:

The height of the triangle = 15 ft

The least required area A = 210 ft^2

We know that the area of a triangle = 1/2bh

Where

b is the base

h is the height

Substituting, we have

210 = 1/2 x b x 15

210 = 15/2 x b

420/15 = b

b = 28 ft

John is approximately 68.26 km away from his starting point after riding 68 km south and then 6 km west.

To find out how far John is from his starting point after riding 68 km south and then 6 km west, we will use the Pythagorean theorem.

The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, we will consider the 68 km south as one side, and the 6 km west as the other side, with the distance from the starting point being the hypotenuse.

Step 1: Square the lengths of the two given sides.
68^2 = 4624
6^2 = 36

Step 2: Add the squared values together.
4624 + 36 = 4660

Step 3: Find the square root of the sum to get the length of the hypotenuse (distance from the starting point).
√4660 ≈ 68.26 km

Answer:

-62 + (-5) = -67

Explanation:

If we need to find a temperature that is 5°C below, we need to subtract 5°C from the initial temperature.

For example, 5°C below 15°C is equal to:

15°C - 5°C = 10°C

If the initial temperature is -62°C, 5°C below is calculated as:

-62°C - 5°C

Since both numbers have a negative sign, we need to add the numbers and the result will also be negative.

It can also be written as:

-62 + (-5) = -67

It means that -67°C is 5°C below -62°C

Step-by-step explanation:

A rhombus diagonal bisect each other so that means half of the diagonal is equal to the other half.

Applying that, this means

Since they are equal we can divide AC by 2 to find AE and EC.

20/2=10

AE=10, EC=10

Same for DB

48/2=24

DE=24, EB=24

A rhombus diagonals are perpendicular to each other so each middle angle will measure 90 degree.

Looking closer, a rhombus has 4 right triangles. We only need to use one.

Look at triangle AEB. We know AE=10 and EB=24 and Angle E=90. We can apply pythagorean theorem to find side AB.

\( {ae}^{2} + {db}^{2} = {ab}^{2} \)

\( {10}^{2} + {24}^{2} = {ab}^{2} \)

\(100 + 576 = ab {}^{2} \)

\(676 = {ab}^{2} \)

\( \sqrt{676} = 26\)

The perimeter of rhombus is equal to

4a, where a is the length of one side.

One side measures 26 so we can plug that in.

\(26 \times 4 = 104\)

The equation of the line that passes through these coordinates is 3x-4y= 36

If you have the coordinates of two points on a line, you can use the slope formula to determine that line's slope. m=(y2-y1)/(x2-x1), or the ratio of the change in the y values to the change in the x values, is the slope formula.

To find the equation of the line we first have to find the slope which is represented by m.

The slope or m is given by : y₂ - y₁ / x₂ - x₁

thus, m= 3-(-12)/ 16-(-4)

m= 3+12/ 16+4 = 15/20

m= 3/4

The equation of a slope is y-y₁=m (x-x₁)

y- (-12) = 3/4 (x- (-4))

y+12 = 3/4 (x+4)

On solving it further we get:

4y+48= 3x+12

3x-4y= 36

Step-by-step explanation:

Theresa and Raul have approximately $264,875.60 in equity in their house after making 120 monthly payments. Emon’s balloon payment at the end of 7 years is approximately $190,347.68.

Let’s calculate the equity that Theresa and Raul have in their house now:

1. Initial purchase price: $200,000

Down payment: 20% of $200,000 = $40,000

Loan amount: $200,000 - $40,000 = $160,000

2. Monthly interest rate: 6% / 12 months = 0.06 / 12 = 0.005

Number of monthly payments: 30 years * 12 months = 360 months

To calculate the monthly payment, we can use the formula for a fixed-rate mortgage:

Monthly payment = P * r * (1 + r)^n / ((1 + r)^n – 1)

Where:

P = Loan amount = $160,000

R = Monthly interest rate = 0.005

N = Number of monthly payments = 360

Using this formula, we can calculate the monthly payment:

Monthly payment = $160,000 * 0.005 * (1 + 0.005)^360 / ((1 + 0.005)^360 – 1)

             ≈ $959.37

Now, let’s calculate the total amount paid over the 120 monthly payments:

Total amount paid = Monthly payment * Number of monthly payments

                = $959.37 * 120

                = $115,124.40

Finally, to calculate the equity, we subtract the total amount paid from the current house value:

Equity = Current house value – Total amount paid

      = $380,000 - $115,124.40

      = $264,875.60

Therefore, Theresa and Raul have approximately $264,875.60 in equity in their house now.

Now let’s calculate Emon’s balloon payment at the end of 7 years:

1. Loan amount: $280,000

2. Monthly interest rate: 2.9% / 12 months = 0.029 / 12 = 0.00242

Number of monthly payments: 7 years * 12 months = 84 months

To calculate the monthly payment, we can use the same formula as before:

Monthly payment = P * r * (1 + r)^n / ((1 + r)^n – 1)

Where:

P = Loan amount = $280,000

R = Monthly interest rate = 0.00242

N = Number of monthly payments = 360

Using this formula, we can calculate the monthly payment:

Monthly payment = $280,000 * 0.00242 * (1 + 0.00242)^84 / ((1 + 0.00242)^84 – 1)

             ≈ $1,125.32

Since the monthly payments are based on a 30-year amortization, at the end of 7 years, there will still be a remaining balance on the loan.

Remaining balance = Loan amount – (Monthly payment * Number of monthly payments)

                = $280,000 – ($1,125.32 * 84)

                ≈ $190,347.68

Therefore, Emon’s balloon payment at the end of 7 years would be approximately $190,347.68.

Therefore, the area inside one loop of the curve is 1/2 square units.

The curve is a limacon with a loop. Using polar coordinates, the equation can be written as:

r = √(8sin(8))

The area inside one loop of the curve is given by:

A = (1/2) ∫θ2 -θ1 r(θ)² dθ

where θ1 and θ2 are the angles at which the curve intersects itself and forms a loop.

Solving for r(θ) = √(8sin(8)), we get:

A = (1/2) ∫0^(π/4) [√(8sin(8))]² dθ

Simplifying, we get:

A = 2 ∫0^(π/4) sin(8) dθ

Using the substitution u = 8θ, du/dθ = 8, and dθ = du/8, we get:

A = (1/4) ∫0^2π sin(u) du

In the number 89.567, the least value is 0, which is the least value of the decimal part of the number. The integer part of the number, which is 89, is greater than 0, so the least value in the number is in the decimal part.

After considering the given data we conclude that the correct statement that satisfy the given question is \(f(n) = 2 - n\)concerning nonnegative integer.

The given definition is a valid recursive definition of a function f from the set of nonnegative integers to the set of integers. The formula for f(n)
Here,
n = nonnegative integer is f(n) = 2 - n.
Now to evaluate that this formula is valid, we can apply mathematical induction.
First, we show that the formula holds for n = 0. Since f(0) = 1 by definition, we have f(0) = 2 - 0 = 1.
Next, we assume that the formula holds for some arbitrary nonnegative integer k.
That is, we assume that f(k) = 2 - k. We then show that the formula also holds for k + 1. By definition of the function f, we have f(k + 1) = f(k) - 1. Substituting our assumption into this equation gives:

f(k + 1) = (2 - k) - 1 = 1 - k

This is precisely the formula we would expect if f(k + 1) were equal to 2 - (k + 1). Therefore, by mathematical induction, we have shown that the formula \(f(n) = 2 - n\)is valid for all nonnegative integers n.

Heteroskedasticity in the errors has an impact on the accuracy of the standard errors estimated using Ordinary Least Squares (OLS) and can affect hypothesis tests. To address this concern, it is advisable to utilize robust standard errors, which provide more reliable inference regarding the parameters of interest.

In the presence of heteroskedasticity, the OLS estimator for the parameters remains unbiased, but the usual OLS standard errors reported by statistical packages become inefficient and biased. This means that the estimated standard errors do not accurately capture the true variability of the parameter estimates. As a result, hypothesis tests based on these standard errors, such as the t-test and F-test, may yield misleading results.

To address heteroskedasticity, robust standard errors can be used, which provide consistent estimates of the standard errors regardless of the heteroskedasticity structure. These robust standard errors account for the heteroskedasticity and produce valid hypothesis tests. They are calculated using methods such as White's heteroskedasticity-consistent estimator or Huber-White sandwich estimator.

In summary, heteroskedasticity in the errors affects the accuracy of the OLS standard errors and subsequent hypothesis tests. To mitigate this issue, robust standard errors should be employed to obtain reliable inference on the parameters of interest.

The expression \(t^2 + 4t - 77\) can be factored as

The general form of the quadratic expression is \(ax^2 + bx + c\), where a, b, and c are coefficients.

Here, a = 1, b = 4, and c = -77.

First, we find two numbers that multiply to c and add up to b. In this case, -7 and 11 fit the criteria.

Now, we write the expression as:

\(t^2 + 4t - 77 = (t + 7)(t - 11)\)

So the expression \(t^2 + 4t - 77\) can be factored as (t + 7)(t - 11) using the area model.

The distributive property states that for any numbers a, b, and c, we have \(a(b + c) = ab + ac.\)

Here, we can factor the expression \(t^2 + 4t - 77\)as:

\(t^2 + 4t - 77 = t^2 + (4 * 11)t - (7 * 11)\)

\(= t^2 + 44t - 77\)

Now, we can use the distributive property to factor the expression as:

\(t^2 + 44t - 77 = (t + 11)(t + 7)\)

So the expression \(t^2 + 4t - 77\) can be factored as (t + 11)(t + 7) using the distributive property.
