How much money does Barbara Mack owe at the end of 4 years if 6% interest is compounded continuously on her $2000 debt? Use the formula A=P e^rt to solve.

The amount of money owed is $ ? Round to the nearest cent as needed.

Answers

A = P*e^(r*t)
A = 2000*e^(0.06*4)
A = 2,542.49830064302
A = 2,542.50

The answer is 2,542.50

Barbara Mack owes approximately $2543.78 at the end of 4 years with 6% interest compounded continuously.

To find the total amount Barbara Mack owes after 4 years with a 6% continuously compounded interest rate, we use the formula:

A = P[tex]e^{rt}[/tex]

with P = $2000,

r = 0.06, and

t = 4

A = 2000 x [tex]e^{0.06 * 4}[/tex].

When we calculate e(0.06*4), we'll get a certain number that you then multiply by 2000 to find the total amount owed.

A= 2000 x [tex]2.71828 ^{0.24}[/tex]

A= 2543.78 ( approx)

So, Barbara Mack owes approximately $2543.78 at the end of 4 years with 6% interest compounded continuously.

The average annual cinema admission price y​ (in dollars) from 2003 through 2012 is given by y=0.28x+5.92. In this​ equation, x represents the number of years after 2003.
a. Complete the table.
x: 2, 5, 8
y:
b. Find the year in which the average cinema admission price was approximately ​$7.88. ​(Hint:Find x when y=7.88 and round to the nearest whole​ number.)
c. Use the given equation to predict when the cinema admission price might be ​$10.04. ​(Use the hint for part​ b.)

Answers

So, you take the equation for y given, y=0.28x+5.92. Then you substitute the values for x in, like so: 
y=0.28(2)+5.92=6.42
y=0.28(5)+5.92=7.17
y=0.28(8)+5.92=7.92
So There's your table. Next:
7.88=0.28x+5.92
x=7, so the year when admission was approximately $7.88 is year 7. 
Next, 
10.04=0.28x+5.92
x=14.7142857143, which rounds to year 15. 
I hope this helps!

Final answer:

By applying the given linear equation, we can calculate the average cinema admission price for specific years, find out in which year the price was approximately $7.88, and predict when it might reach $10.04.

Explanation:

The question involves solving a linear equation to complete a table, find a specific year based on the ticket price, and predict when the ticket price will reach a certain amount. To complete these steps, we apply the equation y=0.28x+5.92, where x represents the number of years after 2003, and y gives the price in dollars.

For a, plug in the values of x (2, 5, 8) into the equation to find y.

For b, set y=7.88 and solve for x (years after 2003) by rearranging the equation.

For c, with a target price of $10.04, use the equation again to solve for x.

When x=2, y=6.48.

When x=5, y=7.32.

When x=8, y=8.16.

For a ticket price of $7.88, solve for x: x =  (7.88 - 5.92) / 0.28 = 7 years after 2003, which is 2010.

To predict when the ticket price reaches $10.04, solve for x: x =  (10.04 - 5.92) / 0.28 = 14.71, rounding to 15 years after 2003, which is 2018.

Over the weekend, Statton and Tyler drove to Montana to go hunting. Now they're preparing to go hunting. Tyler needs gas for his jeep, which gets 22 miles gallon for gas mileage. When he stops at the gas station, he already has 5 gallons of gas in his tank, he buys more gas for $1.25 per gallon. If Tyler spends $22 on gas, what is the total distance the boys could travel?

Answers

Answer:

497.2 miles

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

To begin solving this problem we first need to calculate how much gas Tyler has in his jeep after stopping at the gas station. We calculate this by multiplying the total bill by the price per gallon of gas, and then we add the amount that was left in the tank.

[tex](22/1.25)+5 = 22.6gallons[/tex]

After stopping at the gas station Tyler has 22.6 gallons of gas in his jeep. Since he gets 22 miles per gallon we multiply this by the amount of gallons in his car to calculate the distance they can travel.

[tex]\frac{22.miles}{gallon} * 22.6gallons = 497.2miles[/tex]

Tyler and his friends can travel 497.2 miles with the amount of gas they have.

If 10 cars are sold to a rental company, what is the probability that at most 3 cars have at least one surface flaw?

Answers

Given a Poisson distribution with 0.05 flaws/sq ft and 10 sq ft panels, each car has a 60.65% chance of no flaws.

The probability of at least 1 car with flaws is 99.35%.

Considering only 1 car with flaws, the final probability of at most 1 car with flaws is 90.2%.

Probability of at most 1 car with flaws: 90.2%

Here's how to calculate the probability that at most 1 car out of 10 has any surface flaws, given the Poisson distribution parameters:

1. Define parameters:

Mean flaws per square foot (λ) = 0.05

Area of plastic panel per car (A) = 10 square feet

Number of cars (N) = 10

2. Calculate probability of no flaws:

Probability of no flaws in one car (P(X=0)) = e^(-λA) = e^(-0.0510) ≈ 0.6065

3. Calculate probability of 1 car with flaws (complementary probability):

Probability of at least 1 car with flaws (1 - P(no flaws in all cars))

P(X ≥ 1) = 1 - (P(X=0))^N = 1 - (0.6065)^10 ≈ 0.9935

Probability of exactly 1 car with flaws (P(X=1)) = N * P(X=0) * (1-P(X=0))^N-1

≈ 10 * 0.6065 * (1 - 0.6065)^9 ≈ 0.3869

4. Final probability:

Probability of at most 1 car with flaws (P(X ≤ 1)) = P(X=0) + P(X=1) ≈ 0.6065 + 0.3869 ≈ 0.9934

The probability that at most 1 car out of 10 has any surface flaws is approximately 90.2%.

Therefore, Given a Poisson distribution with 0.05 flaws/sq ft and 10 sq ft panels, each car has a 60.65% chance of no flaws.

The probability of at least 1 car with flaws is 99.35%.

Considering only 1 car with flaws, the final probability of at most 1 car with flaws is 90.2%.

The probable question may be: The number of surface flaws in plastic panels used in the interior of automobile has a Poisson distribution with a man of 0.05 flaws per square foot of plastic panel. Assume an automobile interior contains 10 square feet of plastic panel. If 10 cars are sold to a rental company, what is the probability that at most 1 car has any surface flaws?

a. The probability of no surface flaws in an auto's interior is approximately 0.7408.

b. The probability of none of the 10 cars having any surface flaws is approximately 0.0498.

c. The probability of at most 1 car having any surface flaws is approximately 0.9631.

a. Probability of no surface flaws:

Calculate the lambda parameter: The lambda parameter for the Poisson distribution represents the expected number of flaws, which is calculated as the mean flaws per square foot multiplied by the total area.

In this case, [tex]\lambda[/tex] = 0.03 flaws/sq ft * 10 sq ft = 0.3 flaws.

Use the Poisson probability formula: The probability of no flaws (x = 0) in a Poisson distribution is given by [tex]e^{(-\lambda)[/tex].

Plugging in lambda = 0.3, we get

P(x = 0) = [tex]e^{(-0.3)[/tex] ≈ 0.7408.

b. Probability of none of the 10 cars having flaws:

Treat each car as an independent event: Since the flaws are random and independent for each car, we can treat each car as a separate event with the same probability of no flaws (0.7408) calculated in part (a).

Calculate the combined probability: To get the probability of none of the 10 cars having flaws, we simply multiply the individual probabilities.

P(no flaws in all 10 cars) = [tex](0.7408)^{10[/tex] ≈ 0.0498.

c. Probability of at most 1 car having flaws:

Calculate probabilities for 0 and 1 flaws: We need the probabilities of 0 flaws (already calculated in part (a)) and 1 flaw (x = 1) to determine the probability of at most 1 flaw.

Probability of 1 flaw: Using the Poisson formula again,

P(x = 1) = [tex]\lambda[/tex] * [tex]e^{(-\lambda)[/tex] = 0.3 * [tex]e^{(-0.3)[/tex] ≈ 0.2222.

Probability of at most 1 flaw: This includes both scenarios with 0 and 1 flaws. P(at most 1 flaw) = P(0 flaws) + P(1 flaw) = 0.7408 + 0.2222 ≈ 0.9631.

Question:-

Step-by-step explanation:

*Note:  

You could derive the Taylor Series for sin(x) using Taylor polynomials differentiation but usually you have to memorize it.

We are given the integral and are trying to find the infinite series of it:

[tex]\displaystyle \int {\frac{sin(x)}{2x}} \, dx[/tex]

We know that the power series for sin(x) is:

[tex]\displaystyle sin(x) = \sum^{\infty}_{n = 0} \frac{(-1)^nx^{2n + 1}}{(2n + 1)!}[/tex]

To find the power series for  [tex]\displaystyle \frac{sin(x)}{2x}[/tex], divide the power series by 2x:

[tex]\displaystyle \frac{sin(x)}{2x} = \sum^{\infty}_{n = 0} \bigg[ \frac{(-1)^nx^{2n + 1}}{(2n + 1)!} \cdot \frac{1}{2x} \bigg][/tex]

Simplifying it, we have:

[tex]\displaystyle \frac{sin(x)}{2x} = \sum^{\infty}_{n = 0} \frac{(-1)^nx^{2n}}{2(2n + 1)!}[/tex]

Rewrite the original integral:

[tex]\displaystyle \int {\frac{sin(x)}{2x}} \, dx = \int {\sum^{\infty}_{n = 0} \frac{(-1)^nx^{2n}}{2(2n + 1)!}} \, dx[/tex]

Integrate the power series:

[tex]\displaystyle \int {\frac{sin(x)}{2x}} \, dx = \sum^{\infty}_{n = 0} \frac{(-1)^nx^{2n + 1}}{2(2n + 1)(2n + 1)!}} + C[/tex]

To find tan x/2, given that tan x=3 and x terminates in π < x < (3π/2), we can use the half-angle formula for tangent. The half-angle formula for tangent is tan(x/2) = ±√((1-cosx) / (1+cosx)). Since tan x=3, we need to find the value of cos x first.

Given that tan x = 3, we can use the fact that tan x = sin x / cos x to find the value of cos x. Rearranging the equation, we have cos x = sin x / tan x = 1 / 3. Now, we can substitute this value of cos x into the half-angle formula to find tan (x/2).

tan (x/2) = ±√((1-cos x) / (1+cos x))
tan (x/2) = ±√((1-1/3) / (1+1/3))
tan (x/2) = ±√((2/3) / (4/3))
tan (x/2) = ±√(2/4)
tan (x/2) = ±√(1/2)
tan (x/2) = ±1/√2

write the complex number -12+16i in trigonometric form r(cos theta+i sin theta), with theta in the interval

Answers

First identify which quadrant we are in:
x = real = -12
y = imaginary = 16
(-12,16) is in 2nd quadrant, this means theta is between 90 and 180.

Next calculate "r", which is distance from (-12,16) to origin:
[tex]r = \sqrt{x^2 +y^2} = \sqrt{12^2 + 16^2} = \sqrt{400} = 20[/tex]
Finally, calculate theta:
[tex]\theta = \tan^{-1}(\frac{y}{x}) = \tan^{-1} (\frac{16}{-12}) = 126.87[/tex]
Note: when you put this in your calculator it will give you -53.13 (4th quadrant)
Just add 180 so that angle is in correct quadrant.
Final Answer:
[tex]-12 + 16i = 20(\cos 126.87 + i \sin 126.87)[/tex]

Two dice are rolled one after another. Construct a sample space and determine the probability that the sum of the dots on the dice total a number greater than 4 if the second die is a 3.

Answers

Final answer:

To find the probability of the sum of two dice being greater than 4 given the second die is a 3, first identify the sample space for the first die as {1, 2, 3, 4, 5, 6}. Then, calculate the favorable outcomes where the first die, added to 3, results in a number greater than 4, which are {2, 3, 4, 5, 6}. The probability is 5/6, rounded to approximately 0.8333.

Explanation:

Sample Space and Probability Calculation

When two dice are rolled one after another, and the second die results in a 3, we consider the outcomes of the first die only. As the first die is also a fair, six-sided die with faces numbered from 1 to 6, the sample space for the first die is S = {1, 2, 3, 4, 5, 6}.

The question asks for the probability of the sum being greater than 4 given that the second die is a 3. This means we are looking for the sum to be 5 or more. We can calculate the possible outcomes where the first die, when added to 3, results in a total greater than 4.

If the first die shows 1, the sum is 4 (not greater than 4).If the first die shows 2, the sum is 5 (which is greater than 4).If the first die shows 3, 4, 5, or 6, the sum is 6, 7, 8, or 9, respectively (all greater than 4).

Therefore, the outcomes in the sample space that result in a sum greater than 4 are {2, 3, 4, 5, 6}. The probability of this event, given the second die is a 3, is the number of favorable outcomes divided by the total number of possible outcomes of the first die. There are 5 favorable outcomes and 6 possible outcomes, so the probability is 5/6 or approximately 0.8333 when rounded to four decimal places.

Final answer:

To construct the sample space, we need to consider all possible outcomes of rolling two dice. The probability of the sum of the dots on the dice being greater than 4 given that the second die is a 3 is 5/36.

Explanation:

To construct the sample space, we need to consider all possible outcomes of rolling two dice. Since each die has six sides numbered 1 to 6, the sample space will consist of 36 outcomes. We can represent the outcomes as pairs of numbers, where the first number represents the result of the first die and the second number represents the result of the second die. For example, (1, 1) represents both dice landing on 1, (1, 2) represents the first die landing on 1 and the second die landing on 2, and so on.

To determine the probability of the sum of the dots on the dice being greater than 4 given that the second die is a 3, we need to identify the outcomes where the second die is 3 and the sum is greater than 4. These outcomes are (2, 3), (3, 3), (4, 3), (5, 3), and (6, 3). There are a total of 5 outcomes that satisfy these conditions. Since the sample space has 36 outcomes, the probability is 5/36. To find the probability that the sum of the dots on two dice is greater than 4 given the second die is a 3, we list the possible outcomes for the first die as {1, 2, 3, 4, 5, 6}. The favorable outcomes are those that, when added to 3, result in a number greater than 4: {2, 3, 4, 5, 6}. This results in a probability of 5/6.

Ariadne shadow is 15 feet long and Dixons shadow is 18feet long. If Ariadne is 5 feet tall how tall is dixon?

Answers

Use a proportion.

                 Shadow Length                  Real Height
Ariadne                15 ft                              5 ft
Dixon                   18 ft                                x

15 is to 5 as 18 is to x

15/5 = 18/x

Solve for x.
Final answer:

Using the concept of similar triangles, we found that Dixon's height is 6 feet, assuming that the light source causing the shadows is consistent.

Explanation:

This question is about the concept of similar triangles in Mathematics. If Ariadne's shadow is 15 feet long and she is 5 feet tall, it means the ratio of her height to her shadow length is 5:15 or 1:3. If Dixon's shadow is 18 feet long, and we assume the light source creating the shadows is the same, then the same ratio can apply to him, since their shadows will be proportional to their heights. Therefore, if the ratio of Ariadne's height to her shadow length is equal to the ratio of Dixon's height to his shadow length, we can form the following equation and solve for Dixon's height: 5/15 = x/18 where 'x' is Dixon's height. Solving this equation, we find that Dixon's height is 6 feet.
