You are driving (too fast) down a straight, country road. The posted limit is 40 miles per hour along this road. Two police officers are posted one mile apart along this road tracking vehicle speeds and are in contact with each other. At the first officer’s position, you drive by going 39 miles per hour. At the second officer’s position 63 seconds later, you drive by going 38 miles per hour. The second officer pulls you over and gives you a ticket. Were they justified in giving you a ticket, even though you were not caught speeding?

Hint: refer to the Mean Value Theorem to assist with your justification and reasoning.

Answers

Answer 1

Yes, they justified giving us a ticket, even though we were not caught speeding, because we drove at a speed higher than the posted speed limit.

It is given that we are driving down a straight country road. The posted limit is 40 miles per hour along this road. Two police officers are posted one mile apart along this road, tracking vehicle speeds, and are in contact with each other. At the first officer’s position, we drive by going 39 miles per hour. At the second officer’s position, 63 seconds later, we drive by, going 38 miles per hour.

The second officer pulls us over and gives us a ticket. We will use the mean value theorem to check whether getting a ticket was justified or not. Let the maximum speed be "v" that we reach between the officers at time "c". Let the function f(t) denote the distance at time "t".

f'(c) = [f(b) - f(a)]/(b - a)

v = (1 - 0)/(63 - 0)

v = 1/63 miles per second

We need to convert the speed into miles per hour.

v = 3600/63 = 57.143 miles per hour

The speed is higher than the posted speed limit. Hence, they justified giving us a ticket, even though we were not caught speeding.

Trevor is planning a 30-day trip to Africa, where he will visit three countries: first Benin,
then Ghana and then Togo. He wants to spend at least 2 and at most 12 days in Benin, at most 13 days
in Ghana, and at most 9 days in Togo. How many such itineraries are possible? (Assume that each day is
spent in just one country, and that she travels from one country to another at night.

Answers

The value of 12 - x can at most be 4 for the given inequality and it is true therefore, all itineraries are possible.

What is inequality?

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

Inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

Let's say the day spend in Benin, Ghana and Togo are B, G, and T respectively.

As per the given,

B + G + T = 30

Here, 2 ≤ B ≤ 12, G ≤ 13, and T ≤ 9.
(12 - B) + (13 - G) + (9 - T) = -30 + 12 + 13 + 9 = 4

Also, B ≥ 2 or B ≤ -2 ⇒ 12 - B ≤ 12 - 2 = 10

Hence "The value of 12 - x can at most be 4 for the given inequality and it is true therefore, all itineraries are possible".

Answers

The coordinates of the image of the point (−9,−3) under the same translation will be (-7,-5).

What is geometric transformation?

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

It is given that the image of the point (-3, -6) under a translation is (-1, -8).

The coordinate by which the first given condition is translated as,

(-3, -6) - (x,y) =  (-1, -8)

(x,y) = (-3, -6) - (-1, -8)

(x,y) =(-3-(-1), -6-(-8)

(x,y) =(-3+1),(-6+8)

(x,y) =(-2,+2)

The coordinates of the image of the point (-9, -3) are under the same translation obtained as,

=(−9,−3)- (-2,+2)

=(-9-(-2) , (-3-(+2))

=(-9+2),(-3-2)

= -7,-5

Thus, the coordinates of the image of the point (−9,−3) under the same translation will be (-7,-5).

A store purchased a digital camera and marked it up 100% from the original cost of $863.57. A week later the store placed the digital camera in sale for 40% off. What was the discount price?

Answers

Answer:

$1036.28

Step-by-step explanation:

Marking something up by 100% means doubling the price. Let's do this step first:

863.57 * 2 = 1727.14

Next, the discount is 40%

I would find this by taking the 10% value, multiplying that by 4 and subtracting that from our new value

10% = 172.714

40% = 690.856

Now our newest value:

1727.14 - 690.856

1036.284

Round to 2 decimal places (as is proper when dealing with cents):

1036.28

Thus, our newest (discounted) price is:

$1036.28

Answers

The probability that the tenth person randomly interviewed in that city is the fifth one to own a dog = 0.051

Given,

Consider the interview of a person is a trial.

Lets consider it success if a person  owns a dog and consequently , a person without a dog will be a failure.'

Let the random variable X represent the number of persons to be interviewed to get 5 dog owner: in other words, to get 5 successors.

Probability of a success in each trial is p = 0.3. Therefore probability of a failure in each trial is q = 1 - p = 0.7 .

Because trials are independent. X has a negative binomial distribution with parameters k = 5, p = 0.3

P(X =x ) = b(x: k, p) = [tex][(x-1)(k-1)] p^kq^r^-^k[/tex]

where, x = k , k + 1 , k + 2......(1)

Now, Lets find the probability that the tenth person randomly interviewed in that city is the fifth one to own a dog

Using equation (1), we get:

P(X = 10) = b(10: 5, 0.3)

A polynomial that satisfies given conditions is:

In this question, we need to find a polynomial that satisfies given conditions.

We have been given that -9i is a root of polynomial.

This means, the conjugate of -9i that is, 9i must be a root of polynomial p.

From given information we can say that the zeros of polynomial p(x) must be (x - 1), (x + 9i), and (x - 9i)

So, we get a polynomial p(x) = 0

(x - 1)(x + 9i)(x - 9i) = 0

(x - 1)(x² - (9i)²) = 0

(x - 1)(x² - (-81)) = 0

(x - 1)(x² + 81) = 0

Considering the discrete probability distribution, it is found that:

a) The mean is of: 6.3

b)

The variance is of: 4.01.The standard deviation is of: 2.

What are the statistical measures for the discrete probability distribution?

The mean of the distribution is given by the sum of each outcome multiplied by it's probability, hence it is obtained as follows:

E(X) = 0.1 x 2 + 0.3 x 5 + 0.4 x 7 + 0.2 x 9 = 6.3.

The variance of the distribution is given by the sum of the difference squared between each observation and the mean, multiplied by it's probability, hence it is obtained as follows:

Var(X) = 0.1 x (2 - 6.3)² + 0.3 x (5 - 6.3)² + 0.4 x (7 - 6.3)² + 0.2 x (9 - 6.3)² = 4.01.

The standard deviation is the square root of the variance of the distribution, hence it is obtained as follows:

S(X) = sqrt(4.01) = 2.

markus makes $65,500 annually. assuming markus is paid on the 1st and the 15th of every month, calculate his earnings

Answers

Markus' biweekly earnings (gross pay every two weeks) are $2,727.16.

How is the biweekly earnings determined?

The annual gross pay can be divided by 26 to get the biweekly earnings.

Another way to compute the biweekly earnings is by adding up the withholding taxes, deductions, and net earnings.

In practice, the net earnings are equal to the gross pay less withholding taxes and deductions.

Annual gross pay = $65,500

Payment period = biweekly (1st and 15th every month)

Withholding taxes:

Social Security = $156.19

Medicare =            36.53

Federal tax  =     445.96

Total withholding = $636.68

Deductions:

Retirement = $45

Health Insurance = $200

Total deductions = $245

Net Earnings = $1,845.48

Biweekly ross pay (earnings) = $2,727.16 ($636.68 + $245 + $1,845.48)

Thus, Markus earns $2,727.16 every two weeks.

Answers

1. The revised annual depreciation on December 31, 2022, is $3,650.

2. The journal entry to record depreciation on December 31, 2022 is as follows:

Journal Entry:

Debit Depreciation Expense $3,650

Credit Accumulated Depreciation $3,650

To record the depreciation expense for the year.

3. The balance in Accumulated Depreciation for Equipment on December 31, 2022, is $37,150.

Cost of equipment = $75,000

Purchase date = July 1, 2019

Estimated useful life = 5 years

Salvage value = $8,000

Depreciable amount = $67,000 ($75,000 - $8,000)

Annual depreciation expense = $13,400 ($67,000/5)

Accumulated Depreciation for two and half years to December 2021 = $33,500 ($13,400 x 2.5)

Book value after 2.5 years = $41,500 ($75,000 - $33,500)

New estimated useful life = 10 years

Revised salvage value = $5,000

Revised depreciable amount = $36,500 ($41,500 - $5,000)

Revised annual depreciation expense = $3,650 ($36,500/10)

Accumulated Depreciation on December 31, 2022 = $37,150 ($33,500 + $3,650)
