Answers
a. To prove that for all n ≥ 0: an = 5.3 + 7(an-1) + an-2 + an-3, we will use mathematical induction.
Base Case: For n = 0, we have a0 = 5.3 + 7(a-1) + a-2 + a-3. Substituting the given initial values, we get a0 = 5.3 + 7(29) + 12 + 0 = 213.3.
Inductive Hypothesis: Assume that for some k ≥ 0, the statement holds true, i.e., ak = 5.3 + 7(ak-1) + ak-2 + ak-3.
Inductive Step: We need to prove that the statement holds for k+1, i.e., ak+1 = 5.3 + 7(ak) + ak-1 + ak-2.
Using the recurrence relation, we have ak+1 = b = 5.3 + 7(ak) + ak-1 + ak-2.
Now, by the inductive hypothesis, ak = 5.3 + 7(ak-1) + ak-2 + ak-3. Substituting this into the equation above, we get:
ak+1 = 5.3 + 7(5.3 + 7(ak-1) + ak-2 + ak-3) + ak-1 + ak-2
= 5.3 + 37.1 + 49(ak-1) + 7ak-2 + 7ak-3 + ak-1 + ak-2
= 52.4 + 48(ak-1) + 8ak-2 + 7ak-3.
This shows that ak+1 can be expressed in the desired form, completing the inductive step. Therefore, by mathematical induction, we have proven that for all n ≥ 0: an = 5.3 + 7(an-1) + an-2 + an-3.
b. The given recurrence relation, an = an-1 + an-2 + an-3, does not match the desired statement, an ≤ 3^n. Hence, it is not possible to prove an ≤ 3^n using the given recurrence relation.
c. The given recurrence relation, an = an-1 - 6an-2 + an-3, does not match the desired statement, an ≤ (amount of money that is greater than or equal to 13 cents). Hence, it is not possible to prove an ≤ (amount of money that is greater than or equal to 13 cents) using the given recurrence relation.
d. To prove that if you only have 3 cent and 5 cent coins available, you can generate any amount of money that is greater than or equal to 8 cents, we will use the concept of the Chicken McNugget theorem.
The Chicken McNugget theorem states that for any two relatively prime positive integers a and b, the largest integer that cannot be expressed as a linear combination of a and b (i.e., ax + by where x and y are non-negative integers) is ab - a - b.
In this case, a = 3 cents and b = 5 cents, which are relatively prime since their greatest common divisor is 1. Applying the Chicken McNugget theorem, the largest integer that cannot be expressed as a linear combination of 3 and 5 is 3 * 5 - 3 - 5 = 7.
Thus, any amount of money greater than or equal to 8 cents can be formed using only
3 cent and 5 cent coins. This can be achieved by adding the appropriate number of 5 cent coins and/or 3 cent coins to reach the desired amount, as long as it is at least 8 cents.
For example, to make 8 cents, you can use one 5 cent coin and one 3 cent coin. For 9 cents, you can use three 3 cent coins. By applying this approach, any amount greater than or equal to 8 cents can be formed using only 3 cent and 5 cent coins.

Part A
Find the magnitude of the ladybug's displacement vector.
Part B
Find the direction of the ladybug's displacement vector.
Answers
The turntable turns through a 45.0 degree angle, the radial line also rotates by 45.0 degrees. Therefore, the direction of the ladybug's displacement vector is 45.0 degrees counterclockwise from the positive x-axis.
Part A:
The radius of the turntable is half of the diameter, which is 6.0 in. The ladybug crawls in a straight radial line to the edge, which means its displacement vector is equal to the radius of the turntable. Therefore, the magnitude of the ladybug's displacement vector is 6.0 in.
Part B:
The direction of the ladybug's displacement vector is the same as the direction of the radial line from the center of the turntable to the edge. This direction can be described by the angle between the positive x-axis and the radial line.
Since the turntable turns through a 45.0 degree angle, the radial line also rotates by 45.0 degrees. Therefore, the direction of the ladybug's displacement vector is 45.0 degrees counterclockwise from the positive x-axis.

The blanket is 2.25 metres long and 1.8 metres wide. what is the area of the blanket? write the answer in centimetres.
Answers
$13608
Explanation:Amount saved by Bao per month = $179
Amount saved by Bao per month = Ada's savings - 179
Amount saved by Ada = $179 + $145
Amount saved by Ada per month = $324
time = three and a half years
We convert years to months:
12 months = 1 year
time = 3(12) + 1/2(12) = 36 + 6
time = 42 months
Amount Ada saved = $324 × number of months
Amount Ada saved = $324 × 42
Amount Ada saved = $13608

supposed that x1 and x2 have the bivariate normal distribution with means mu1 and mu2, and variances s1 and s2 and correlation rho. find the distribution of x1 - 3x2
Answers
The distribution of X₁ - 3X₂ is a normal distribution with mean μ₁ - 3μ₂ and variance s₁² + 9s²₂ - 6rhos₁s₂.
To find the distribution of X₁ - 3X₂, we need to find the mean and variance of this new variable.
The mean of X₁ - 3X₂ is:
E(X₁- 3X₂) = E(X₁) - 3E(X₂) = μ₁ - 3μ₂
The variance of X₁ - 3X₂ is:
Var(X₁ - 3X₂) = Var(X₁) + 9Var(X₂) - 6Cov(X₁,X₂)
Since X₁ and X₂ have a bivariate normal distribution with means μ₁ and μ₂, variances s₁ and s₂ and correlation rho, we know that:
Var(X₁) = s²₁
Var(X₂) = s²₂
Cov(X₁,X₂) = rhos₁ s₂
Substituting these values into the variance equation, we get:
Var(X₁ - 3X₂) = s₁² + 9s²₂ - 6rhos₁s₂.

You just bought a used car for $12,000 with no down payment using dealer financing at 4% APR compounded monthly. If you make monthly payments of $300, how many months will it take you to payoff the loan? Your Answer: Answer Question 9(0.5 points) You want to borrow $15,000 to buy a new car. Your annual interest rate is 5.9% over 5 years with monthly payments. Calculate your monthly payment. Your Answer:
Answers
your monthly payment for borrowing $15,000 over 5 years with an annual interest rate of 5.9% and monthly payments will be approximately $283.89.
To calculate the number of months required to pay off the loan, we can use the loan repayment formula:
n = -log(1 - (r * PV) / PMT) / log(1 + r)
Where:
n = Number of months
PV = Loan amount (purchase price of the car)
PMT = Monthly payment
r = Monthly interest rate (APR divided by 12)
Substituting the given values, the formula becomes:
n = -log(1 - (0.04/12 * 12000) / 300) / log(1 + 0.04/12)
Simplifying this expression, we find:
n ≈ 40
Therefore, it will take approximately 40 months to pay off the loan for the used car.
Moving on to the second question, to calculate the monthly payment for borrowing $15,000 over 5 years with an annual interest rate of 5.9% and monthly payments, we can use the loan payment formula:
PMT = PV * (r *\((1 + r)^n\)) / (\((1 + r)^n\) - 1)
Where:
PMT = Monthly payment
PV = Loan amount
r = Monthly interest rate (annual interest rate divided by 12)
n = Number of months (5 years * 12 months per year)
Substituting the given values, the formula becomes:
PMT = 15000 * (0.059/12 * (\((1 + 0.059/12)^(5*12)\))) / (\((1 + 0.059/12)^(5*12)\) - 1)
Calculating this expression, we find:
PMT ≈ $283.89

Answers
A graph of the resulting triangles after a reflection over the line y = -1 and over the y-axis is shown in the images below.
How to transform the coordinates of triangle ABC?In Mathematics, a reflection across the line y = k and y = -1 can be modeled by the following transformation rule:
(x, y) → (x, 2k - y)
(x, y) → (x, -2 - y)
Ordered pair A (0, 2) → Ordered pair A' (0, -4).
Ordered pair B (-8, 8) → Ordered pair B' (-8, -10).
Ordered pair C (0, 8) → Ordered pair C' (0, -10).
By applying a reflection over the y-axis to the coordinate of the given triangle ABC, we have the following coordinates for triangle A"B"C":
(x, y) → (-x, y).
Ordered pair A (0, 2) → Ordered pair A" (0, 2).

over the course of a year, malachi gets 2 haircuts at a price of $12.00 each, 3 haircuts at a price of $15.00 each, and 1 haircut at a price of $25.00. for malachi,what is the weighted mean cost of a haircut?
Answers
The weighted mean cost of a haircut for Malachi is $15.67, divided by the total number of haircuts, which comes to 6, to yield a total cost of $94.00.
We must compute the total cost of all haircuts and divide it by the total number of haircuts in order to determine the weighted mean price of a haircut for Malachi. The expense of each haircut must be weighed according to the frequency with which it occurred, though, because they varied in price.
To begin, let's figure out how much each haircut will cost overall:
2 haircuts at $12.00 each = $24.00
3 haircuts at $15.00 each = $45.00
1 haircut at $25.00 = $25.00
Total cost = $24.00 + $45.00 + $25.00 = $94.00
Next, We must determine the total number of cuts:
2 haircuts + 3 haircuts + 1 haircut = 6 haircuts
Finally, The weighted mean cost of a haircut can be determined by dividing the total cost by the total number of haircuts:
The weighted mean cost of a haircut = Total cost / Total number of haircuts
= $94.00 / 6 haircuts
= $15.67 per haircut (rounded to the nearest cent)
Therefore, Malachi's weighted mean haircut expense is $ 15.67 , divided by the total number of haircuts, which comes to 6, to yield a total cost of $94.00.
