Check the picture below.

The true statement is,

⇒ The total fare changes by $3 per kilometer, and it will cost $22 for a distance of 6 kilometers.

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The graph shows the taxi fare. y, in is city, for a distance of x kilometers.

Now,

Since, The graph shows the taxi fare. y, in is city, for a distance of x kilometers.

Let two points on the graph are (2, 10) and (4, 16).

Hence, The slope of the line = (16 - 10) / (4 - 2)

                                             = 6/2

                                             = 3

Thus, The equation of line for the graph is,

⇒ y - 10 = 3 (x - 2)

⇒ y - 10 = 3x - 6

⇒ y = 3x - 6 + 10

⇒ y = 3x + 4

For 6 kilometer, the cost is find as;

Substitute x = 6;

⇒ y = 3x + 4

⇒ y = 3 × 6 + 4

⇒ y = 22

Therefore, The total fare changes by $3 per kilometer, and it will cost $22 for a distance of 6 kilometers.

Answer:

The amplitude of the function y=2*sin(x) is 2. The amplitude is the maximum value of the function, and in this case, the maximum value of y is 2.

The period of the function y=2*sin(x) is 2π. The period is the distance in the x-axis between two points at which the function has the same value. And in this case, the function reaches the maximum value of 2 at x = π/2, and the next time it reaches the same value is x = 3π/2, which is a distance of 2π in the x-axis.

The total amount of money Williams will pay if he downloaded 45 song is 36.5 dollars.

A. Work shows that as the probability of success approaches 0, the standard deviation decreases and approaches 0.

The standard deviation for the binomial distribution with a probability of success p = 0.017 for 20 trials would be 0.282. The standard deviation for a binomial distribution can be calculated using the formula =√np(1−p).

Inserting the values for n = 20, p = 0.017 gives us an answer of 0.282. As the probability of success approaches 0, the standard deviation decreases and approaches 0.

This is because as the probability of success approaches 0, the number of successes in the trials approaches 0, so there is less variation in the number of successes and the standard deviation approaches 0.

a) To calculate the after-tax cost of debt, we first need to calculate the pre-tax cost of debt, which is the coupon interest rate. In this case, the bond has a coupon interest rate of 8%. We then need to multiply this by (1-tax rate) to get the after-tax cost of debt. In this case, the firm is in a 40% tax bracket, so:

After-tax cost of debt = 8% x (1 - 40%) = 4.8%

b) To calculate the cost of preferred stock, we need to know the dividend yield, which is the annual dividend payment per share divided by the price per share. In this case, the preferred stock does not have any dividends, so its cost of capital is 0%.

c) To calculate the cost of new common stock, we need to know the dividend yield, which is the annual dividend payment per share divided by the price per share. We also need to know the rate of growth in dividends. In this case:

Dividend yield = Dividend per share / Price per share

Dividend yield = 7 / 90 = 0.0778

Cost of new common stock = (Dividend per share / Price per share) + (Dividend growth rate)

Cost of new common stock = 0.0778 + 0.06 = 13.78%

d) To calculate the firm's weighted average cost of capital (WACC), we need to use the capital structure weights and the costs of each type of capital. In this case:

WACC = (Weight of debt x After-tax cost of debt) + (Weight of preferred stock x Cost of preferred stock) + (Weight of new common stock x Cost of new common stock)

Note: These weights can be calculated from the proportion of each source of financing in the firm's capital structure.

WACC = (0.354.8%) + (00%) + (0.65*13.78%) = 7.63%.

The firm's weighted average cost of capital using retained earnings and the capital structure weights is 7.63%.

Cost of capital is the minimum rate of return or profit a company must earn before generating value. It's calculated by a business's accounting department to determine financial risk and whether an investment is justified.

The height of BC is calculated from the knowledge of similar triangles to be 2.76 m

This is a term used in geometry to mean that the respective sides of the triangles are proportional and the corresponding angles of the triangles are congruent

Hence assuming the corresponding angles of the triangle are congruent then the side should be in proportions

Examining the figure shows that pair of equivalent sides are

AE and DE, AC and BC.

The solution is worked out using the proportion as follows

AE / DE = AC / BC

5 / 0.92 = (5 + 10) / BC

5 * BC = 0.92 * 15

BC = 2.76 m

2x + 3y = 120

There is no number that I can substitute for 2x and 3y and get two different answers (60 and 120)

2x + 3y = -60

2x + 3y = 120 ⇒ multiply all the way through by -1 ⇒ -2x -3y = -120

You want to solve this system of equations by graphing and by substitution.

The graph of the system of equations is attached. The solution is ...

  (x, y) = (1, 4)

Using the second equation, we can write an expression for y:

  y = 2x +2

Substituting that into the first equation gives ...

  3x = 3 . . . . . . . . subtract 2

  x = 1

Then ...

  y = 2(1) +2 = 4

The solution is (x, y) = (1, 4).

Step-by-step explanation:

For f(x) = -2x² + 8x + 1

To find the y-intercept, set x = 0 and determine the value for f(x). This will work out to +1 so the y-intercept is (0, 1)

To find the vertex y-value. Note that we are given the x value as 2. Substitute 2 for x in the function expression. This will give you a value of 9. So the vertex is (2, 9)

The coefficient of x² is negative so it will be a maximum vertex and therefore opens downward

For g(x) = 3x² + 6x -4

To find the x value of the vertex, differentiate with respect to x and set this first derivative equal to zero

First derivate of g(x), g'(x) = 6x + 6

Set 6x + 6 =0 to get x = -1

The axis of symmetry is nothing but the x value of the vertex and therefore x = -1

The coefficient of x² is positive. So the vertex will be a minimum and it will be an upward opening parabola

An algebraic expression in mathematics is an expression created using variables, constant algebraic numbers, and algebraic operations. A collection of one or more linear equations containing the same variables is known as a system of linear equations in mathematics. A set of two or more linear equations with two or more variables each constitutes a system of linear equations, all of which are taken into account simultaneously. Finding a numerical value for each variable in the system that will simultaneously satisfy all of the system's equations is necessary to identify the one and only solution to a system of linear equations.

A y-intercept, also known as a vertical intercept, is the location where the graph of a function or relation intersects the coordinate system's y-axis. This is done in analytic geometry using the common convention that the horizontal axis represents the variable x and the vertical axis the variable y. These points satisfy x = 0 because of this.

In mathematics, the slope or gradient of a line is a number that indicates the line's steepness as well as its X and Y directions.
