The magnitude of the vector sum (A + B) is approximately 4.974.

To find the magnitude of the vector sum (A + B), we need to add the corresponding components of vectors A and B and then calculate the magnitude of the resulting vector.

Given:

Vector A: (5.1, 0)

Vector B: (-2.6, -4.3)

To find the vector sum (A + B), we add the corresponding components:

(A + B) = (5.1 + (-2.6), 0 + (-4.3))

= (2.5, -4.3)

Now, let's calculate the magnitude of the vector (2.5, -4.3):

Magnitude = sqrt((2.5)^2 + (-4.3)^2)

= sqrt(6.25 + 18.49)

= sqrt(24.74)

≈ 4.974

Answer:

the value of {f/g}(5) is 10.8.

Step-by-step explanation:

To find the value of {f/g}(5), we need to evaluate the function f(x)/g(x) at x = 5.

First, let's calculate f(5) and g(5):

f(5) = 7 + 4(5) = 7 + 20 = 27

g(5) = (1/2)(5) = 5/2 = 2.5

Now, we can find {f/g}(5) by dividing f(5) by g(5):

{f/g}(5) = f(5) / g(5) = 27 / 2.5 = 10.8

If the function f(x)=7+4x and g(x)=1/2x, the value of {f/g}(5) is 10.8.

To calculate the value of {f/g}(5), substitute x = 5 into the expression for f(x) and g(x) and then divide f(5) by g(5).

Given that:

f(x) = 7 + 4x

g(x) = (1/2)x

f(5) = 7 + 4(5)

= 7 + 20

= 27

So,

g(5) = (1/2)(5)

= 5/2

= 2.5

Hence,

{f/g}(5) = f(5) / g(5)

= 27 / 2.5

= 10.8

Thus, 10.8 is the value of {f/g}(5).

The equation f(x) = k * (x + 2) / [(x - 5) * (x - 1)] could represent the given rational function with an x-intercept at (-2, 0) and vertical asymptotes at x = 5 and x = 1.

To write an equation that represents the given rational function with an x-intercept at (-2, 0) and vertical asymptotes at x = 5 and x = 1, we can start by considering the factors in the numerator and denominator of the function.

Since the function has an x-intercept at (-2, 0), it means that the numerator of the function has a factor of (x + 2).

Since the function has vertical asymptotes at x = 5 and x = 1, it means that the denominator of the function has factors of (x - 5) and (x - 1).

Putting these factors together, the equation that could represent this function is:

f(x) = k * (x + 2) / [(x - 5) * (x - 1)]

Here, k represents a constant multiplier that scales the function, and it can be any non-zero constant value.

The true statements are: The balance of Account A is growing at a rate of 5% per year. Account A is growing faster than Account B.

Let's analyze each statement one by one:

The balance of Account A is growing at a rate of 5% per year.

This statement is true. The equation for Account A is A(x) = 900(1.05)^x, where x represents the number of years after 2012. The term (1.05)^x accounts for the growth rate of 5% per year.

Account C had the largest balance in the year 2012.

This statement cannot be determined based on the given information. The equations only provide the balance after a certain number of years, but they do not provide the balances in the year 2012. Without the initial balances, we cannot determine which account had the largest balance in 2012.

Account A is growing faster than Account B.

This statement is true. Comparing the growth rates in the equations, we can see that the growth rate of Account A is 5% per year (multiplied by 1.05), while the growth rate of Account B is 3.8% per year (multiplied by 1.038). Therefore, Account A is growing faster than Account B.

The balance of Account C is decreasing at a rate of 85% per year.

This statement is false. The equation for Account C is C(x) = 5000(0.85)^x, where x represents the number of years after 2012. The term (0.85)^x represents a decrease of 15% per year, not 85% per year. Therefore, the balance of Account C is decreasing at a rate of 15% per year, not 85% per year.

[tex]\frac{1}{2}[/tex]  pound chocolate

Let x be the number of pounds of chocolate that needs to be mixed.

The cost of the chocolate is $14.60 per pound, so the cost of x pounds of chocolate is 14.6x dollars.

The cost of the trail mix is $4.40 per pound, so the cost of 12 pounds of trail mix is 4.4(12) = 52.8 dollars.

The cost of the mixture is $9.70 per pound, so the cost of (x + 12) pounds of the mixture is 9.7(x + 12) dollars.

We can set up an equation based on the fact that the total cost of the mixture equals the sum of the costs of the individual components:

14.6x + 52.8 = 9.7(x + 12)

Simplifying and solving for x, we get:

14.6x + 52.8 = 9.7x + 116.4

4.9x = 63.6

x = 12.98

Rounding to the nearest pound, we get x = 13.

Therefore, the store owner should mix 13 pounds of chocolate with 12 pounds of trail mix to create a mixture worth $9.70 per pound.

To sketch the given equations, we will start with the graph of the original function f(x) = 2/(x-2) + 2 and then apply the necessary transformations.

1. y = f(x-2):

To sketch y = f(x-2), we need to shift the graph of f(x) two units to the right. This can be done by replacing x in the equation f(x) with (x-2). The equation becomes y = f(x-2) = 2/((x-2)-2) + 2 = 2/(x-4) + 2.

2. y = f(x-1) - 3:

To sketch y = f(x-1) - 3, we need to shift the graph of f(x) one unit to the right and three units downward. This can be done by replacing x in the equation f(x) with (x-1) and subtracting 3 from the result. The equation becomes y = f(x-1) - 3 = 2/((x-1)-2) + 2 - 3 = 2/(x-3) - 1.

Now, let's plot these equations on a graph:

Note: The graph of the original function f(x) = 2/(x-2) + 2 should be sketched first before applying the transformations.

To find the area of the rectangular window in square inches, we need to convert the dimensions from feet to inches. Since there are 12 inches in a foot, we can multiply the length and width of the window by 12 to get the measurements in inches.

Length of the window: 4 ft * 12 in/ft = 48 inches

Width of the window: 2 ft * 12 in/ft = 24 inches

Now, we can calculate the area of the window by multiplying the length and width:

Area = Length * Width

Area = 48 inches * 24 inches

Area = 1152 square inches

Therefore, the area of the rectangular window is 1152 square inches.

The volume of a cylinder is base are of a circle multiplied by the height of the cylinder

The dimensions of the lot that maximize the enclosed area are 150 meters in width and 300 meters in length.

To find the dimensions of the lot that maximize the enclosed area, we can use the concept of calculus and optimization.

Let the width of the lot as 'w' and the length of the lot as 'l.'

Given that the lot is bordered on one side by a stream and on the other three sides by 600m of fencing,

we can set up the equation for the perimeter of the lot:

Perimeter = 600m

Since the length of the lot is bounded by the stream and the width is bounded by the remaining three sides, we have:

Length (l) + 2 × Width (w) = 600m

We may use the constraint equation to solve for one variable in terms of the other since we need to represent the area of the lot in terms of just one variable.

l = 600m - 2w

The area (A) of the lot is given by:

A = Length × Width

Substituting the value of l from the constraint equation, we have:

A = (600m - 2w) × w

A = 600w - 2w²

To find the maximum area, we differentiate A with respect to w and set it equal to zero:

dA/dw = 600 - 4w = 0

Solving this equation, we find:

4w = 600

w = 150m

Substituting the value of w back into the constraint equation, we can solve for l:

l = 600m - 2(150m)

l = 300m

Therefore, the dimensions of the lot that maximize the enclosed area are 150 meters in width and 300 meters in length.

The average amount the player can expect to win or lose per game over the long run. In this game, the Expected value is x/1000.

The expected value for the numbers game, we need to calculate the weighted average of the possible outcomes.

In this game, there are 1000 possible numbers that can be selected, ranging from 000 to 999. If the player selects the winning number, they win a certain amount, and if they select any other number, they win nothing.

Let's assume the amount won is $x when the winning number is selected

The probability of selecting the winning number is 1/1000 because there is only one winning number out of the 1000 possible numbers.

The probability of not selecting the winning number is 999/1000 because there are 999 other numbers that can be selected.

The expected value (EV) can be calculated using the following formula:

EV = (Amount won if winning number is selected) * (Probability of winning) + (Amount won if losing number is selected) * (Probability of losing)

In this case, the EV is:

Answer: B. Yellow

Step-by-step explanation: Yellow has the largest number of students out of the entire data set, so it will consume the largest area on a pie chart.

Answer:

A pie chart is a type of graph that shows the relative sizes of different categories of data by dividing a circle into sectors or slices. Each sector represents a fraction of the whole circle, which is equal to 100%. The angle of each sector is proportional to the percentage of the data it represents. To answer a question based on a pie chart, we need to compare the sizes of the sectors and find the one that matches the given condition.

For example, consider the following question:

When asked their favorite color, 20 students said red, 23 students said blue,

25 students said green, and 28 students said yellow. Students with which

favorite color would be represented by the largest wedge in a pie chart?

To answer this question, we need to find the total number of students who participated in the survey. We can do this by adding up the numbers of students who chose each color:

20 + 23 + 25 + 28 = 96

Next, we need to find the percentage of students who chose each color by dividing the number of students by the total and multiplying by 100:

Red: (20 / 96) x 100 = 20.83%

Blue: (23 / 96) x 100 = 23.96%

Green: (25 / 96) x 100 = 26.04%

Yellow: (28 / 96) x 100 = 29.17%

Finally, we need to compare the percentages and find the largest one. In this case, it is yellow with 29.17%. Therefore, students who chose yellow as their favorite color would be represented by the largest wedge in a pie chart.

The answer is B. Yellow.
