The nearest tenth how many miles is alshleys house from Bridget house is  AB = √[(xB-xA)² + (yB-yA)²]

The nearest tenth how many miles is Ashley’s house from carlys house is AC = √[(xC-xA)² + (yC-yA)²]

The distances from Ashley's house to both Bridget's house and Carly's house, we can compare them and see which one is shorter.

To find the distance between Ashley's house and Bridget's house, we need to know the coordinates of both locations. Let's say Ashley's house is located at point A, and Bridget's house is located at point B. We can use the distance formula to find the distance between A and B:

distance AB = √[(xB-xA)² + (yB-yA)²]

Here, xA and yA represent the coordinates of Ashley's house, and xB and yB represent the coordinates of Bridget's house. The formula calculates the square root of the sum of the squares of the differences between the x-coordinates and y-coordinates of the two points.

To find the distance between Ashley's house and Carly's house, we again need to know the coordinates of both locations. Let's say Ashley's house is located at point A, and Carly's house is located at point C. We can use the same distance formula as before:

distance AC = √[(xC-xA)² + (yC-yA)²]

Here, xC and yC represent the coordinates of Carly's house. Plug in the values and calculate the distance to the nearest tenth of a mile.

To determine whose house Ashley lives closest to, we need to calculate the distances from Ashley's house to both Bridget's house and Carly's house. Whichever house has the shorter distance will be the closer one.

To find the difference between the two distances, we can subtract the smaller distance from the larger distance.

Step-by-step explanation:

The probability that on a particular Monday, they each suggest a different activity is 0.11.

The probability that in a period of four consecutive Mondays, they all suggest the same activity on exactly two of the four Mondays is 0.0504.

1. Probability that on a particular Monday, they each suggest a different activity:

The probability is calculated using the formula below:

Probability = P(SMC) + P(MCS) + P(CSM)

Probability = (0.4 x 0.55 x 0.5) + (0.3 x 0.2 x 0.3) + (0.3 x 0.25 x 0.2)

Probability = 0.11

2. The probability that in a period of four consecutive Mondays, they all suggest the same activity on exactly two of the four Mondays is determined using the binomial distribution.

Let success be suggesting the same activity on exactly two of the four Mondays.

The probability of success on any Monday is:

P(success) = P(SSNN) + P(NSSN) + P(NNSS)

P(success) = 3 x (0.4 x 0.4 x 0.6 x 0.6)

P(success) = 0.3456

The probability of failure is:

P(failure) = 1 - P(success)

P(failure)= 1 - 0.3456

P(failure) = 0.6544

Choose exactly two Mondays out of four is ⁴C₂

The probability of exactly two successes = ⁴C₂ * P(success)² * P(failure)²

P(exactly 2 successes) = 6 x (0.3456)² x (0.6544)²

P(exactly 2 successes) = 0.0504 or 5.04%

f'(x) = (-2e^(-x) + 1/x)·(9x^2.5) + (2e^(-x) + ln(x))·(22.5x^1.5)

To find the derivative of f(x) = g(x) · h(x), we'll use the product rule, which states that (u·v)' = u'·v + u·v'. Let u = g(x) and v = h(x).

u = g(x) = 2e^(-x) + ln(x)
v = h(x) = 9x^2.5

Ion has a total of $4,378.05 in his savings account at the end of 3 years.

To solve this problem, we need to use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the total amount of money in the account at the end of the time period

P = the principal amount (initial deposit)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time period (in years)

In this case, we have:

P = $120

r = 0.029 (2.9% expressed as a decimal)

n = 12 (compounded monthly)

t = 3 (years)

We also need to calculate the total number of deposits made during the 3-year period. Since a deposit of $120 is made at the end of every month, and there are 12 months in a year, the total number of deposits made is:

12 deposits/year × 3 years = 36 deposits

Now we can plug in the values into the formula:

A = [tex]120(1 + 0.029/12)^(12 × 3) + 120[(1 + 0.029/12)^(12 × 3) - 1]/(0.029/12)[/tex]

Sine and cosine are both equivalent to x/y, depending on the angle of the point on the circle.

To find two trigonometric functions equivalent to the ratio x/y, we can use the unit circle. Let's assume that x and y are the coordinates of a point on the circle, where x represents the horizontal displacement, and y represents the vertical displacement.

From this, we can find that the sine of the angle that x and y make with the x-axis is y, and the cosine of that angle is x. Therefore, the two trigonometric functions equivalent to the ratio x/y are sine and cosine.

We can write this as sin(angle) = y/y and cos(angle) = x/y. It's important to note that the value of the angle depends on the position of the point on the unit circle.

So, sine and cosine are both equivalent to x/y, depending on the angle of the point on the circle.

Answer: $108,972

Step-by-step explanation:

To find the current value of Lawrence's condominium, we need to calculate the 8% increase in value over the past 2 years.

First, find the increase in value:

$100,900 * 0.08 = $8,072

Next, add this increase to the original price:

$100,900 + $8,072 = $108,972

So, the current value of Lawrence's condominium is $108,972.

1. The income on your monthly budget is $2,932.24. 2. The realized income on your budget is $2,876.25.

1. To calculate the net income after deductions, we first need to find the amount deducted for each tax.

FICA deduction = 7.65% of gross income = 0.0765 x 3500 = $267.75

Federal tax withholding = 10.75% of gross income = 0.1075 x 3500 = $376.25

State tax withholding = 8.35% of gross income = 0.0835 x 3500 = $292.25

Total deductions = FICA + Federal tax withholding + State tax withholding = $267.75 + $376.25 + $292.25 = $936.25

Net income = Gross income - Total deductions = $3,500.00 - $936.25 = $2,563.75

Adding the income from the second job, the total income on the monthly budget is:

Total income = Net income + Second job income = $2,563.75 + $368.49 = $2,932.24

2. Let x be the realized income on the budget. We know that fixed expenses are 36% of realized income, so we can set up a proportion:

Fixed expenses / Realized income = 36% / 100%

or

$1,035.65 / x = 0.36 / 1

Cross-multiplying, we get:

x = $1,035.65 / 0.36 = $2,876.25

Therefore, the realized income on the budget is $2,876.25.

Step-by-step explanation:

The radius of convergence is 1/3. To find the radius of convergence for the power series using the ratio test, we need to analyze the general term of the series. The given series is:

Σ(an * x^n)

where an is the coefficient of the term with x raised to the power n. The coefficients in the given series are:

a1 = 3
a2 = 36
a3 = 243
a4 = 1296
a5 = 6075
...

Notice that each coefficient is a multiple of 3^n. Thus, we can write the general term as:

an = 3^n

Now, we apply the ratio test. The ratio test states that the series converges if the limit as n approaches infinity of the absolute value of the ratio of consecutive terms is less than 1:

lim (n → ∞) |(a(n+1) * x^(n+1)) / (an * x^n)|

= lim (n → ∞) |(3^(n+1) * x^(n+1)) / (3^n * x^n)|

To simplify, divide 3^(n+1) by 3^n:

= lim (n → ∞) |(3 * x)|

The series converges when |3 * x| < 1. To find the radius of convergence, solve for |x|:

|x| < 1/3

The number of P50, P100, and P20 bills Mr. Pilo got is calculated as follows;

Amount from P50-bills: 2/5 x P1,000 = P400

Amount from P100-bills: 1/2 x P1,000 = P500

The total amount he received from the P50-bills and P100-bills = P400 + P500

The total amount he received from the P50-bills and P100-bills = P900. The amount left to be changed into P20-bills = P1,000 - P900

The amount left to be changed into P20-bills = P100.

Yes, there is reason to doubt the randomness of the jury selection based on the information provided.

Given data:

Out of the 20 potential jurors, 8 were African American and 12 were white. The probability of randomly selecting an African American juror from the pool of potential jurors would ideally be 8/20, which simplifies to 2/5 or 40%. However, the actual jury selected had only 1 African American member out of 6 jurors, which is significantly lower than the expected 40% if the selection were truly random.

This deviation from the expected probability raises questions about the randomness of the selection process. The observed outcome appears to be disproportionately skewed against the representation of African American jurors. While random variations can occur, the extent of the deviation in this case warrants further investigation into the jury selection process to determine if there were any biases or factors influencing the outcome.

Answer:

11.86 units

Step-by-step explanation:

Volume = length x width x height

We know that the volume is 210 and the width is 5 3/5 (or 5.6) and the height is 3 1/3 (or 3.33).

Substituting these values into the formula, we get:

210 = length x 5.6 x 3.33

To solve for the length, we can divide both sides of the equation by (5.6 x 3.33):

length = 210 / (5.6 x 3.33)

Simplifying this expression, we get:

length ≈ 11.86

Therefore, the length of the large box is approximately 11.86 units.

The conversion is given as follows:

123 pounds per mile = 0.01 ounces per cm.

The conversion is obtained applying the proportions in the context of the problem.

There are 16 ounces in 1 pound, hence the number of ounces in 123 pounds is given as follows:

the formula for ak, we can set up a system of linear equations using the given values for ao, aj, and Ak+1.

Let x = ak-1 and y = ak. Then we have:

2 = a0 = x
4 = a1 = y
Ak+1 = 10ak-1 + 9ak

Substituting x and y, we get:

Ak+1 = 10(2) + 9(4) = 56

So we have the system of equations:

x = 2
y = 4
y = 10x + 9y

Rewriting the third equation, we get:

-10x + y = 0

Adding the first two equations, we get:

x + y = 6

Solving this system of equations, we get:

x = 2
y = 4

Therefore, ak = 4 for all k > 0.

To find lim kak, we can use the formula for ak:

lim kak = lim 4 = 4

So the limit of ak as k approaches infinity is 4.
To find the formula for a_k using linear algebra, we can first form a system of linear equations using the given recurrence relation:

a_(k+1) = 10a_(k-1) + 9a_k

Since we know a_0 = 2 and a_1 = 4, we can start by finding a_2:

a_2 = 10a_0 + 9a_1 = 10(2) + 9(4) = 20 + 36 = 56

Next, we can find a_3 using a_1 and a_2:

a_3 = 10a_1 + 9a_2 = 10(4) + 9(56) = 40 + 504 = 544

Now, we can represent this system of linear equations in matrix form:

[ [ 1  0 ]   [ a_0 ]   [  2 ]
 [ 0  1 ] * [ a_1 ] = [  4 ]
 [ 10 9 ] * [ a_2 ] = [ 56 ]  
 [ 10 9 ] * [ a_3 ] = [ 544 ] ]

We can then use methods of linear algebra such as Gaussian elimination, Cramer's rule, or matrix inversion to solve the system and find a_k.

However, this particular system does not provide a direct formula for a_k. Moreover, as the given information doesn't suggest a converging series, we cannot determine the limit as k approaches infinity (lim k→∞ a_k).
