Step-by-step explanation:

The cost of a taxi ride that is m miles long can be represented by the equation: Cost of ride, m miles = $2 + $1.50m

To calculate the cost of a taxi ride for 9 miles, we need to consider the fixed pickup cost of $2 and the additional cost per mile driven, which is $1.50.

For the 9-mile ride, the additional cost would be:

Additional Cost = $1.50 per mile × 9 miles = $13.50

Adding the pickup cost and the additional cost gives us the total cost of the ride:

Total Cost = Pickup Cost + Additional Cost = $2 + $13.50 = $15.50

Therefore, the cost of the taxi ride for 9 miles would be $15.50.

For a taxi ride that is m miles long, we can use the same formula. The additional cost would be:

Additional Cost = $1.50 per mile × m miles = $1.50m

The total cost of the ride would then be:

Total Cost = Pickup Cost + Additional Cost = $2 + $1.50m

This formula allows us to calculate the cost of the taxi ride for any given number of miles, represented by the variable m.

Dividing two polynomials may produce another polynomial only when the divisor has a lower degree than the dividend. Otherwise, it will generally result in a rational function.

No, dividing two polynomials may not result in another polynomial. It can produce a rational function.

A polynomial is an algebraic expression consisting of terms with non-negative integer exponents. When two polynomials are divided, the result is not always a polynomial.

If the degree of the polynomial being divided (dividend) is higher than the degree of the polynomial dividing (divisor), then the result can be a polynomial with a lower degree. However, if the degree of the divisor is equal to or greater than the degree of the dividend, the result will generally be a rational function, which is a ratio of two polynomials.

A rational function has the form P(x)/Q(x), where P(x) and Q(x) are polynomials and Q(x) is not equal to zero. The division can introduce terms with negative or fractional exponents, making the result a rational function rather than a polynomial.

answer 2. should be right

200 is the mean absolute deviation. Therefore, choice three (200) is the right one.

The absolute difference between the predicted and actual values must be determined, added together, and divided by the total number of periods.

Forecasted values are as follows: 1,500 and 1,400

Values in actuality: 1,200 and 1,500

Absolute differences:

|1,500 - 1,200| = 300

|1,400 - 1,500| = 100

Now, we calculate the MAD:

MAD = (300 + 100) / 2 = 400 / 2 = 200

The linear function which represents the line is y = - 3x + 14.

What is Point slope form?

Point slope form is used to represent a straight line using its slope and a point on the line. It means that the equation of a line whose slope is 'm' and which passes through a point (x1, y1) is found using the point-slope form.

Main body:

y - y1 = m (x - x1)

where, (x, y) is a random point on the line and m is the slope of the line.

The given point-slope equation is

y + 1 = - 3 (x - 5)

By further calculation

y + 1 = -3x + 15

y = -3x + 15 - 1

y = -3x + 14

Therefore, the linear function which represents the line is y = - 3x + 14.

Answer:

1/2 hours

Step-by-step explanation:

The square root of √(14 - 8√3) simplifies to ±√(14 + 8√3).

To simplify the expression √(14 - 8√3), we can follow these steps:

Let's assume √(14 - 8√3) = x.

Square both sides of the equation to eliminate the square root:

(√(14 - 8√3))² = x²

14 - 8√3 = x²

Rearrange the equation to isolate the radical term:

8√3 = x² - 14

To simplify further, let's solve for x by isolating the radical term:

x² = 8√3 + 14

x² = 14 + 8√3

Now, we can solve for x by taking the square root of both sides:

x = ±√(14 + 8√3)

In order to simplify the phrase (14 - 8), we may do the following:

Assume that (14 - 83) equals x.

To get rid of the square root, square both sides of the equation:

(√(14 - 8√3))² = x²

14 - 8√3 = x²

To find the radical term, reorder the equation:

8√3 = x² - 14

Let's solve for x using the radical term alone to further simplify the problem:

x² = 8√3 + 14 x² = 14 + 8√3

By taking the square root of both sides, we can now find x:

x = ±√(14 + 8√3)

There exists a sequence with a bounded subsequence but no convergent subsequences.

In mathematics, it is possible to have a sequence that contains a subsequence which is bounded but does not have any subsequence that converges. This means that although there are elements within the sequence that are limited within a certain range, there is no specific subsequence that approaches a definite value or limit.

To construct such a sequence, one approach is to alternate between two subsequences. Let's consider an example: {1, -1, 2, -2, 3, -3, ...}. Here, the positive terms form a subsequence {1, 2, 3, ...} which is unbounded, and the negative terms form another subsequence {-1, -2, -3, ...} which is also unbounded. However, no subsequence of this sequence converges because it oscillates between positive and negative values.

Therefore, this example demonstrates a sequence that contains a bounded subsequence but lacks any convergent subsequences.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

We can use the given information to find the rate at which Cassandra is knitting the scarf and the initial length of the scarf.

Let L be the initial length of the scarf in centimeters, and let r be the rate at which Cassandra is knitting the scarf in centimeters per hour. Then, we have:

L + 25h = length of scarf after h hours

Substituting h = 3 and the length of the scarf after 3 hours = 125, we get:

L + 25(3) = 125

L + 75 = 125

L = 50

The linear inequality of the graph is: -x + 2y + 1 > 0

First, we calculate the slope of the dashed line using:

\(m = \frac{y_2 - y_1}{x_2 - x_1}\)

Two points on the graph are:

(1, 0) and (3, 1)

The slope (m) is:

\(m = \frac{1 - 0}{3 - 1}\)

This gives

m = 0.5

The equation of the line is calculated as:

\(y = m(x -x_1) + y_1\)

So, we have;

\(y = 0.5(x -1) + 0\)

This gives

\(y = 0.5x -0.5\)

Multiply through by 2

\(2y = x - 1\)

Now, we convert the equation to an inequality.

The line on the graph is a dashed line. This means that the inequality is either > or <.

Also, the upper region of the graph that is shaded means that the inequality  is >.

So, the equation becomes

2y > x - 1

Rewrite as:

-x + 2y + 1 > 0

So, the linear inequality is: -x + 2y + 1 > 0

The distance between successive fourth roots of the complex number √3/2 - 1/2i on the unit circle is 5π/24 units.

To find the distance between successive fourth roots of a complex number on the unit circle, we can use the concept of the angle between the roots. Let's proceed step by step:

The given complex number is √3/2 - 1/2i. This complex number lies on the unit circle because its magnitude is equal to 1.

1. Convert the given complex number to trigonometric form:

  √3/2 - 1/2i = cos(θ) + i*sin(θ)

  By comparing the real and imaginary parts, we can determine the angle θ:

  cos(θ) = √3/2

  sin(θ) = -1/2

  Using the unit circle, we can find that θ = 5π/6 (or 150 degrees). This angle represents the position of the given complex number on the unit circle.

2. Find the angle between successive fourth roots:

  Since we are interested in the fourth roots, we divide the angle θ by 4:

  θ/4 = (5π/6) / 4 = 5π/24

  This angle represents the angular distance between two successive fourth roots on the unit circle.

3. Calculate the distance between the two points:

  To find the distance, we multiply the angular distance by the radius of the unit circle (which is 1):

  Distance = (5π/24) * 1 = 5π/24

  Therefore, the distance between successive fourth roots of the complex number √3/2 - 1/2i on the unit circle is 5π/24 units.

According to the Pythagoras property,

H denotes hypotenuse

B denotes base

P denotes perpendicular

Here,

→ (x)² = (35 cm)² + (12 cm)²

→ x² = 1225 cm² + 144 cm²

→ x² = 1369 cm²

→ x = √(1369 cm²)

→ x = 37 cm

Therefore, value of x is 37 cm.
