A function is given. g(x)=3−4/5x; x=−5 ,x=4 the net change between the given values of the variable is -7.2. The average rate of change between the given values of the variable is -0.8.

(a) To determine the net change between the given values of the variable, we need to find the difference between the function values at x = -5 and x = 4.

g(-5) = 3 - 4/5(-5) = 3 + 4 = 7
g(4) = 3 - 4/5(4) = 3 - 3.2 = -0.2

Net change = g(4) - g(-5) = -0.2 - 7 = -7.2

(b) To determine the average rate of change between the given values of the variable, we need to find the slope of the secant line between the points (-5, 7) and (4, -0.2).

Average rate of change = (g(4) - g(-5))/(4 - (-5)) = (-7.2)/(9) = -0.8

Therefore, the average rate of change between the given values of the variable is -0.8.

Answer:

Step-by-step explanation:

When writing the equation for a circle on a plane, we use the format:

[tex](x-x_{1})^2+(y-y_{1})^2=r^2[/tex]

x1 and y1 is the point of the center of the circle, which in this case is (1,-2)

r represents the radius, which is the distance from the center to the edge of the circle, which is (4,-2) - (1,-2) = 3

Our equation is now:

[tex](x-1)^2+(y+2)^2=9[/tex]

the reason why its y+2 is because (y-(-2) = (y+2)

r is squared, which is why it's 9 instead of 3. Hope this helps!

Since the two hexagons are similar, their corresponding sides are in the same ratio as the scale factor.

Let x be the length of a side of the smaller hexagon, then the corresponding length of a side of the larger hexagon can be expressed as (3/7)x.

The area of a hexagon can be calculated using the formula: A = (3√3/2)s², where s is the length of a side.

Since the area of the smaller hexagon is 18 m², we can solve for x as follows:

18 = (3√3/2)x²

x² = 12/√3

x = 2√3

Now we can calculate the area of the larger hexagon:

Area of the larger hexagon = (3√3/2)(3/7x)² = (3√3/2)(3/7(2√3))² = 54/49 m²

Finally, we can calculate the volume of the larger hexagon, assuming it is a regular hexagonal prism:

Volume of the larger hexagon = Area of hexagon x Height

The height of the hexagonal prism is the same as the length of the side of the larger hexagon, which is (3/7)x:

Volume of the larger hexagon = (54/49) x (3/7)x = 54/343 x² ≈ 0.212 x²

Substituting the value of x, we get:

Volume of the larger hexagon ≈ 0.212 x (2√3)² = 1.272 m³

Therefore, the volume of the larger hexagon is approximately 1.272 m³.

Well, I'm not sure if it's correct but I got 42.

I got this by doing something along the lines of:

1) 18/x = 3/7

2) Cross multiply

3) 3x = 126

4) Divide both sides by 3

5) x = 42

The polynomial g(x) can be written as the product of linear factors g(x) = (x - 5)(x - 1)(x + 3). Polynomial as the product of linear factors. g(x) = x3 – 3x2 + x + 5 g(x) = (x - 5)(x - 1)(x + 3) and all the zeroes of the function are x = 5, 1, and -3.

To find the zeros of a function, we need to set each factor of the polynomial to zero and solve for x. When x = 5, (x - 5) = 0, when x = 1, (x - 1) = 0, and when x = -3, (x + 3) = 0.

Therefore, the zeros of the function are x = 5, 1, and -3. We can use these zeros to graph the function, as each zero is a point on the x-axis. The graph of this function will have three x-intercepts at the given points. We can also use the zeros to find the y-intercept, which will be the constant term in the polynomial.

In this case, the constant term is 5, so the y-intercept will be (0, 5) the polynomial g(x) = (x - 5)(x - 1)(x + 3) has zeros at x = 5, 1, and -3, and a y-intercept at (0, 5).

Answer:

Step-by-step explanation:

the diameter of the circle is approximately 1.2 kilometers.

We can use the formula for the area of a circle:

Area = pi x (diameter/2)^2

where pi is a constant approximately equal to 3.14, and diameter is the distance across the circle passing through its center.

We are given the area of the circle as 1.1304 square kilometers, so we can substitute this value into the formula and solve for diameter:

1.1304 = 3.14 x (d/2)^2

1.1304 = 0.785d^2

d^2 = 1.1304/0.785

d^2 = 1.440

d = sqrt(1.440)

d ≈ 1.2

Therefore, the diameter of the circle is approximately 1.2 kilometers.

The expected value of the game in which you have a (1/20) chance of winning  is $1.50.  The probability of a student scoring between 75 and 89 is 0.5536. The probability of a student scoring above 85 is 0.4562.

1. To find the expected value of the game, we need to multiply the probability of each outcome by the value of that outcome and then add them together.

E(X) = (1/20)($300 + $15) + (19/20)(-$15)

E(X) = $315/20 - $285/20

E(X) = $30/20

E(X) = $1.50

So the expected value of the game is $1.50.

2. To find the probability of a student scoring between 75 and 89, we need to use the z-score formula:

z = (x - μ)/σ

For x = 75, z = (75 - 84)/9 = -1

For x = 89, z = (89 - 84)/9 = 0.56

Using a z-table, we can find the probability of a student scoring between these two z-scores:

P(-1 < z < 0.56) = P(z < 0.56) - P(z < -1)

P(-1 < z < 0.56) = 0.7123 - 0.1587

P(-1 < z < 0.56) = 0.5536

So the probability of a student scoring between 75 and 89 is 0.5536.

3. To find the probability of a student scoring above 85, we need to use the z-score formula:

z = (x - μ)/σ

For x = 85, z = (85 - 84)/9 = 0.11

Using a z-table, we can find the probability of a student scoring above this z-score:

P(z > 0.11) = 1 - P(z < 0.11)

P(z > 0.11) = 1 - 0.5438

P(z > 0.11) = 0.4562

So the probability of a student scoring above 85 is 0.4562.

I don't know if you meant 2.5 or 25 but ill assume you meant 2.5

Step-by-step explanation:

The given function is a quadratic function with a positive leading coefficient, therefore it opens upwards and has a minimum value. To find the minimum value of the function, we can use the formula:

x = -b/2a

where a = 1 and b = 6 are the coefficients of the quadratic function.

x = -6/2(1) = -3

Substitute x = -3 into the function to find the minimum value:

f(-3) = (-3)^2 + 6(-3) + 11 = 2

Therefore, the minimum value of the function is 2.

The coordinates of the reflected polygon F'G'H'I' are as follows:

F'(-2, -1), G'(5, -4), H'(8, -5), and I'(6, -2).

In mathematics, reflection is defined as the mirror image of a figure crossing a line (drawn or imagined), known as the line of reflection.

The vertices of the polygon FGHI are as follows:

F(2, -1)

G(5, 2)

H(8, 3)

I(6, 0)

To reflect the polygon FGHI across the line y = -1, we need to flip the points over the line.

Now we can reflect each of the points of the polygon across the line y = -1 to get the image:

F(2, -1) stays in the same place because it lies on the line of reflection.

G(5, 2) is reflected to G'(5, -4) by flipping it vertically across the line y = -1.

If Emma needs to travel a distance of 15 miles or less, she should choose the red cab company because it has a lower cost. If she needs to travel more than 15 miles, she should choose the yellow cab company  

From the question, we are to determine which company Emma should use when she wants to minimize cost.

Let's assume that Emma needs to travel a distance of d miles to get to the airport.

The cost C of taking the red cab company can be represented by the function:

Cred(d) = 3.50 + 1.25d

Similarly, the cost C of taking the yellow cab company can be represented by the function:

Cyellow(d) = 5.00 + 1.15d

To determine which company Emma should use to minimize cost, we need to find the value of d that makes the cost of each company equal. In other words, we need to solve the equation:

Cred(d) = Cyellow(d)

Substituting the expressions for Cred(d) and Cyellow(d), we get:

3.50 + 1.25d = 5.00 + 1.15d

Simplifying and solving for d, we get:

0.10d = 1.50

d = 15

To investigate the claim that the shipment contains at most 2% defective items, we can use the 5% level of significance. The claim is that the population proportion of defective items is at most 2%, or p0 ≤ 0.02. The sample size is n = 200, and the sample proportion of defective items is pobs = 10/200 = 0.05.

The test statistic is then:

z = (pobs - p0) / √(p0(1-p0) / n)

= (0.05 - 0.02) / √(0.02(1-0.02)/200)

With a 5% level of significance, we can look up the critical value for a one-tailed z-test and find that it is zα/2 = 1.645. Because 1.02 < 1.645, the test statistic is not greater than the critical value, and thus we fail to reject the null hypothesis that the population proportion of defective items is at most 2%.

The response to the given question would be that The slope of the line is the constant of proportionality if the graph is a straight line through the origin.

Partnerships that have the same ratio across time are said to be proportional. For instance, how many trees there are in an orchard and how many apples there are in a harvest of apples are determined by the average number of apples per tree. Proportional in mathematics refers to a linear connection between two numbers or variables. As the first quantity doubles, so does the other. When one of the variables drops to 1/100th of its previous value, the other also decreases. When two quantities are proportional, it means that as one rises, the other rises as well, and the ratio between the two quantities stays the same at all levels. As an example, consider the diameter and circumference of a circle.  

It is difficult to estimate the constant of proportionality between two variables, y and x, without first viewing the graph.

Nevertheless, the constant of proportionality may be calculated by dividing any y-value by its corresponding x-value if the two variables are directly proportional, which means that when x rises, y rises as well at a consistent pace.

If y = kx, where k is the proportionality constant, then mathematically, k = y/x at every point on the graph.
