The total interest to be paid over the 5-year period is $403.22.

In a loan with a declining balance, interest is added to the outstanding balance at the start of each period, such as each month or each quarter. The outstanding balance, which decreases as the borrower makes repayments, is used to determine the interest rate. As a result, the borrower gradually pays less interest and more of each payment is used to lowering the main balance due. The lowering balance approach is frequently applied to mortgages, personal loans, and auto loans.

Given that, the quarterly installments are $1899.75.

For the entire year for a total of 5 years the total amount is:

Total amount = 4 * 5 * $1899.75 = $37995

For reducing balance loan the interest is calculated as:

For the first quarter, the interest to be paid is:

interest = (total amount - 0) * (0.14 / 4)

interest = (37995 - 0) * (0.14 / 4) = $94.50

Similarly for the remaining quarters we have:

Second quarter = $87.95

Third quarter: $81.05

Fourth quarter: $73.76

Fifth quarter: $65.96

The total interest to be paid over the 5-year period is:

$94.50 + $87.95 + $81.05 + $73.76 + $65.96 = $403.22

Hence, the total interest to be paid over the 5-year period is $403.22.

To convert minutes into seconds, you can multiply the number of minutes by 60, since there are 60 seconds in a minute. For example, if you want to convert 1 minutes into seconds, you would do:

1 minutes ×60 seconds/minute = 60 seconds

Therefore, 5 minutes is equal to 300 seconds.

3 minutes 4 seconds - 1 minute 16 seconds

We can start by subtracting the seconds:

3 minutes - 1 minute = 2 minutes

And add the borrowed 60 seconds to the seconds place:

The equation of the line is y = -2x. The correct option is the last option y = -2x

From the question, we are to write the equation of the line in the given graph using the slope and y-intercept from the graph

First, we will determine the slope of the graph

The slope of the graph calculated from the formula

Slope = Change in y / Change in x

Slope = (y₂ - y₁) / (x₂ - x₁)

Picking the points (-1, 2) and (0, 0)

Slope = (0 - 2) / (0 - (-1))

Slope = -2/(0 + 1)

Slope = -2/1

Thus,

Slope = -2

From the graph, the y-intercept of the graph is 0

Then,

From the slope-intercept form of the equation of a line,

y = mx + c

Where m is the slope

and c is the y-intercepts

Step-by-step explanation:

In scientific notation, a number is written as the product of a decimal number between 1 and 10 and a power of 10. The decimal number is called the mantissa, and the power of 10 is called the exponent. The mantissa indicates the significant digits of the number, while the exponent tells us the size of the number relative to 1. In the given calculator computations, the numbers are already written in scientific notation, where "E" represents the exponent notation. We just need to convert them into the standard form of scientific notation by expanding the notation as a product of the mantissa and the power of 10.

A function is a set of instructions or statements that perform a specific task or computation and returns a value or result. In programming, a function is typically defined using a specific syntax and can be called or invoked by other parts of the program to carry out a particular operation.

Functions are used in programming to break down complex tasks into smaller, more manageable pieces of code, which can then be reused in multiple parts of the program. They can also help to improve the organization, readability, and maintainability of code.

let the worker's original hourly wage be represented by the variable x. Then the function for the worker's new hourly wage when the 20% raise is applied before the $2 raise can be expressed as follows:

[tex]f(x) = (1.20x) + 2[/tex]

In this function, the expression (1.20x) represents the worker's hourly wage after the 20% raise is applied, and the additional $2 raise is added to this amount to determine the final hourly wage.

We can also express this function using function composition notation. Let g(x) represent the function that applies the 20% raise to the worker's hourly wage and let h(x) represent the function that adds the $2 raise to the resulting hourly wage. Then we have:

[tex]g(x) = 1.20x[/tex]

[tex]h(x) = x + 2[/tex]

Using function composition, we can write the function for the worker's new hourly wage as:

Two vectors v₁ and v₂ whose sum are (0, -1, -3), where v₁ is parallel to

(5, 0, -4) while v₂ is perpendicular to (5, 0, -4).

v1 = [40/13, -8/13 ]

v2 = [-1/13,  -5/13]

Parallel vectors will be multiples of each other.

Perpendicular vectors will have a dot product of 0.

Let v₁ = [a, b] and v₂ = [c, d]

v₁ || [-5,1]   means  v₁ = N [-5,1] = [a, b]

So  a = -5N  and b = N  

v₂ • [-5,1] = 0 (because they are perpendicular)

So [c, d] • [-5,1] = -5c + d = 0  or  d = 5c    

⇒ v₁ + v₂ = [a, b] + [c, d] = [3, -1]

So  a + c = 3      and     b + d = -1    

Now,

Substitute -5N for

a.  Substitute N for b.    

and Substitute 5c for d.  

This gives us a system of equations with two equations and 2 unknowns:

-5N + c = 3

 N + 5c = -1

Multiply everything in the  bottom equation by 5

-5N + c = 3

5N + 25c = -5

Now add vertically, eliminating the variable N and finding

26c = -2

or, c = -1/13

Now we work our way backwards.

-5N + c = -5N + (-1/13) = 3

-5N = 40/13

(-1/5) (-5N) = (40/13)(-1/5)

and

N = -8/13  and b = N so b = -8/13

d = 5c so d = -5/13

a = -5N, so a = 40/13

So the two vectors are:

v₁ = [40/13, -8/13 ]

v₂ = [-1/13,  -5/13]

Answer:

Step-by-step explanation:

We can start by assuming that the relationship between the ticket price and attendance is linear, so we can write the equation for the line that connects the two data points we have:

Point 1: (9, 23000)

Point 2: (7, 30000)

The slope of the line can be calculated as:

slope = (y2 - y1) / (x2 - x1)

slope = (30000 - 23000) / (7 - 9)

slope = 3500

So the equation for the line is:

y - y1 = m(x - x1)

y - 23000 = 3500(x - 9)

y = 3500x - 28700

Now we can use this equation to find the attendance for any ticket price. To maximize revenue, we need to find the ticket price that generates the highest revenue. Revenue is simply the product of attendance and ticket price:

R = P*A

R = P(3500P - 28700)

R = 3500P^2 - 28700P

To find the ticket price that maximizes revenue, we need to take the derivative of the revenue equation and set it equal to zero:

dR/dP = 7000P - 28700 = 0

7000P = 28700

P = 4.10

So the ticket price that would maximize revenue is $4.10. However, we need to make sure that this price is within a reasonable range, so we should check that the attendance at this price is between 23,000 and 30,000:

A = 3500(4.10) - 28700

A = 5730

Since 23,000 < 5,730 < 30,000, we can conclude that the ticket price that would maximize revenue is $4.10.

Step-by-step explanation:

Area of triangle = (1/2) · b · h

(1/2) · 3 · 4 = 6 square feet

There are 2 triangles, so we time 2

Area of rectangle = L × W

9 x 4 = 36 square feet

Now we take

12 + 36 = 48 square feet

The frequency in hertz of electromagnetic radiation which has a wavelength of 585nm is 5.13×10¹⁴ Hz.

The frequency(f) of electromagnetic radiation is related to its wavelength (λ) by the equation : f = c/λ;

Where, c = the speed of light in a vacuum, which is  3.00×10⁸ m/s.

So, to calculate the frequency of radiation with a wavelength of 585.0 nm, we need to convert the wavelength to meters:

⇒ 585.0 nm = 585.0×10⁻⁹ m;

Substituting the value in the above formula,

We get,

⇒ f = c/λ = 3.00×10⁸/(585.0×10⁻⁹)

⇒ 5.13×10¹⁴ Hz.

Therefore, the frequency of electromagnetic radiation is approximately 5.13 × 10¹⁴ Hz.

What is Algebraic Equations?

An algebraic equation is also known as a polynomial equation because both sides of the equal sign contain polynomials. An algebraic equation is built up of variables, coefficients, constants as well as algebraic operations such as addition, subtraction, multiplication, division, exponentiation, etc.

To solve the system of equations algebraically, we can set the two expressions for y equal to each other and solve for x:

[tex]-2x + 1 = -2x^2 + 3x + 1[/tex]

Simplifying, we get:

[tex]-2x^2 + 3x + 1 + 2x - 1 = 0[/tex]

[tex]-2x^2 + 5x = 0[/tex]

Factorizing x, we get:

x(-2x + 5) = 0

Therefore, the solutions for x are:

x = 0 or x = 5/2

To find the corresponding values of y, we can substitute these values of x into either of the original equations for y:

For x = 0:

y = -2(0) + 1 = 1

For x = 5/2:

[tex]y = -2(5/2)^2 + 3(5/2) + 1 = -13/2 + 15/2 + 1 = 3[/tex]

Yes, 8 divides n^2 - 1 when n = 4k + 3.

We are given that n = 4k + 3, where k is an integer. We want to determine if 8 divides n^2 - 1, which means we want to know if there exists an integer m such that n^2 - 1 = 8m.

To start, we can rewrite n^2 - 1 as (n + 1)(n - 1). This is a common trick in number theory problems involving divisibility, and it can often help us factorize expressions in a useful way.

Substituting n = 4k + 3, we get:

(n + 1)(n - 1) = (4k + 3 + 1)(4k + 3 - 1) = (4k + 4)(4k + 2)

Now, we want to determine whether 8 divides this expression. In other words, we want to know if there exists an integer m such that:

(4k + 4)(4k + 2) = 8m

We can simplify the left-hand side of this equation by factoring out 4

4(k + 1)(2k + 1) = 8m

Now, we see that 8 divides the left-hand side of the equation, since it is equal to 4 times an even number. Moreover, (k + 1) and (2k + 1) are both integers, so we can conclude that 8 divides n^2 - 1 when n = 4k + 3.

There is a linear function graphed that would pass through the first 4 points, but not the last one;

You can discern this as there is a common pattern we can identify, everytime the x-value increases by 2 the y-value increases by 3, except with the last coordinates;

The rate of change, also known as the gradient, is the change in x divided by the change in y (Δx/Δy);

In the case of the first 4 points, the rate of change would be 3/2 or 1.5;

This simply means when x increases by 1, y increases by 1.5, IF the function is linear;

However, as mentioned the last point doesn't fit the pattern;

There, we can see the y-value increases by 3 when the x-value only increases by 1;

This means the point (0, 23) isnt on the graph of the function, the points (0, 21.5) and (1, 23), on the other hand, would be.
