You deposit $300 in an account that earns simple interest at an annual rate of 6.5%.

If no other deposits or withdrawals were made, what is the total amount of money in the account at the end of 8 years?

Answers

Answer 1

Total amount of money in the account will be $456.

How much money will be in the account after 8 years?

Simple interest is an interest charge that borrowers pay lenders for a loan. It is calculated using the principal only and does not include compounding interest.

The formula for simple interest is: Simple Interest = Principal × Rate × Time

Principal (P) is $300

Rate (R) is 6.5%

Time (T) is 8 years.

Simple Interest = $300 × 0.065 × 8

Simple Interest = $156

Total Amount = Principal + Simple Interest

Total Amount = $300 + $156

Total Amount = $456.

the equation given: f(x) = 2/x-2 +2

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

Answers

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.

Find the expected value for this game and describe what this means.

Answers

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:

EV = (x * 1/1000) + (0 * 999/1000)

  = x/1000

A rectangular lot is bordered on one side by a stream and on the other three sides by 600m
of fencing. Find the dimensions of the lot to maximize the enclosed area.

Answers

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.

To find the missing values, we need additional information about the probabilities of events A and B individually. Specifically, we need either P(A) or P(B) or both.

The probability notation P(B | A) represents the conditional probability of event B occurring given that event A has already occurred. It can be interpreted as the probability of event B happening "under the condition" that event A has already taken place.

A store owner want to develop a new snack mix by mixing chocolate and trail mix. How many pounds of chocolate costing $14.60 per pound should be mixed with 12 pounds of trail mix costing $4.40 per pound to create a mixture worth $9.70 per pound? (round to the nearest pound)

Answers

Answer:

Step-by-step explanation:

[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.

a rectangular window is 4 ft long and 2 ft wide. Martina would like to buy a screen for the window. the the cost of the screen is based on the number of square inches the screen is. use the facts to find the area of the window in square inches ​

Answers

Answer:

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.

Answers

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.

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.

D. Red

Answers

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.

O is the center of the regular dodecagon below. Find its perimeter. Round to the nearest tenth if necessary.

Answers

Answer:

80.55

Step-by-step explanation:

Formula to calculate the perimeter (P) of a regular dodecagon with a radius (r) is:

P = 24 * r * sin(π/12),

where π is approximately 3.14159.

Using this formula, with the given radius of 13, we can calculate the perimeter as follows:

P = 24 * 13 * sin(π/12).

Calculating sin(π/12), we find that it is approximately 0.2588190451.

Substituting this value into the formula, we have:

P = 24 * 13 * 0.2588190451.

Evaluating the expression, we get:

P ≈ 80.55223123.

Therefore, the approximate perimeter of a regular dodecagon with a radius of 13 is approximately 80.55 units.

Perimeter = 12 × 13 × sin(π/12) ≈ 121.41 units

regular dodecagon with a radius of 13.

A regular dodecagon can be divided into 12 congruent isosceles triangles, each with a central angle of 30 degrees (360 degrees divided by 12 sides). The base of each triangle is a side of the dodecagon, and the two equal sides are radii of the dodecagon.

To find the length of the base of each triangle (i.e., the side of the dodecagon), we can use trigonometry. The formula is:

base = 2 * radius * sin(π/12),

where radius is 13 and π is approximately 3.14159.

Substituting the given values into the formula, we have:

base = 2 * 13 * sin(π/12).

Calculating sin(π/12), we find that it is approximately 0.2588190451.

Now we can substitute this value into the formula:

base = 2 * 13 * 0.2588190451.

Evaluating the expression, we get:

base ≈ 6.712685936.

Since there are 12 sides in the dodecagon, the perimeter is the sum of all the sides:

perimeter = 12 * base.

Substituting the value of the base, we have:

perimeter = 12 * 6.712685936.

Calculating the expression, we find:

perimeter ≈ 80.55223123.

Therefore, the approximate perimeter of a regular dodecagon with a radius of 13 is approximately 80.55 units

Answer:

80.8 units

Step-by-step explanation:

We have:

radius(r)=13

no of side(n)=12

First of all, we need side lenght::

we have

[tex]\boxed{\bold{Length \: of\: 1\: side(s)=2 r * sin(\frac{180}{n}})}[/tex]

substituting value:

[tex]\boxed{\bold{Length \: of\: 1\: side(s)=2 *13* sin(\frac{180}{12}})=6.729}[/tex]

now

We have Perimeter= no of side* length of one side=12*6.729=80.78 in nearest tenth it is 80.8 units
