Answers

Answer 1

a) The domain and the range of the function are given as follows:

Domain: [0, 7.1875].Range: [0,23].

The graph of the function is given by the image presented at the end of the answer.

b) The trip was 5.1875 hours long.

What are the domain and the range of a function?

The function for this problem is defined as follows:

g(t) = 23 - 3.2t.

The domain is the set of input values that can be assumed by the function. The time cannot have negative measures, hence the lower bound of the domain is of zero, while the gas cannot be negative, hence the upper bound of the volume is given as follows:

23 - 3.2t = 0

3.2t = 23

t = 23/3.2

t = 7.1875 hours.

The range is given by the set of all output values assumed the function, which are the values of the gas, hence it is [0,23].

The graph is a linear function between points (0, 23) and (7.1875, 0).

At the end of the trip there were 6.4 gallons left, hence the length of the trip is given as follows:

23 - 3.2t = 6.4

t = (23 - 6.4)/3.2

t = 5.1875 hours.

Find the 16th term of the arithmetic sequence described below.
ak = 3 + 4 (k − 1)
Show your work here

Answers

Answer: 63

Step-by-step explanation:

The given arithmetic sequence is defined by the formula:

ak = 3 + 4(k - 1)

To find the 16th term, we can substitute k = 16 into this formula and simplify:

a16 = 3 + 4(16 - 1)

a16 = 3 + 4(15)

a16 = 3 + 60

a16 = 63

Therefore, the 16th term of the arithmetic sequence is 63.

find the point(s) on the surface which are closest to the point . list points as a comma-separated list, (e.g., (1,1,-1), (2, 0, -1), (2,0, 3)).

The points on the surface z² = xy+ 1 which are closest to the point

(7, 11, 0) is x = 2 and y = 10.

The distance of any point on the surface from the point (7, 11, 0)  is

D(x, y) = { [ x -7]2 + [ y -11 ]2 + [ z -0 ]2 } 1/2

D(x, y) = { [ x -7]2 + [ y -11 ]2 +  z 2 } 1/2

D(x, y) = { [ x -7]2 + [ y -11 ]2 + z 2 } 1/2

D(x, y) = { [ x -7]2 + [ y -11 ]2 + x y +1 } 1/2

Now,

To minimize D  suffices to minimize

d (x ,y ) =  [ x -7]2 + [ y -11 ]2 + x y +1

You have three dice in your pocket, one is 4 -sided and two are 6-sided. You randomly select two of the dice, roll them, and record the sum. a. What's the probability the sum is 7 ? b. Given that the sum of the dice is 7 , what's the probability both dice are 6 -sided?

Answers

The probability that  sum of two randomly selected dice is 7 is 1/2. The given that the sum of the dice is 7, the probability that both dice are 6-sided is 1/3.

a. Each pair has a probability of being selected of 1/3 * 1/2 = 1/6. Now sum of the probabilities of the three pairs that have a sum of 7:  P = P(4-6) + P(6-4) + P(6-6) = 1/6 + 1/6 + 1/6 = 1/2

Let f(x) = ex and g(x)=x-3. What are the domain and range of (fog)(x)?

range: y < 0
O domain: x>3
range: y > 0
O domain: all real numbers
range: y < 0
domain: all real numbers
range: y > 0

Answers

Answer:

To find the domain and range of (fog)(x), we need to first find (fog)(x):

(fog)(x) = f(g(x)) = f(x-3) = e^(x-3)

The domain of (fog)(x) is all real numbers because there are no restrictions on the input x that would make e^(x-3) undefined.

To find the range of (fog)(x), we need to determine the possible outputs of e^(x-3). Since e^x is always positive, e^(x-3) is positive for all x. Therefore, the range of (fog)(x) is y > 0.

So, the answer is: D. domain: all real numbers | range: y > 0

What is the measure of angle R?

A) 17 degrees
B) 25 degrees
C) 34 degrees
D) 65 degrees

Answers

Answer: D) Angle R is 65 degrees

Step-by-step explanation:

In the given figure, we have a right-angled triangle PQR.

Using the property of angles in a triangle, we know that the sum of angles in a triangle is 180 degrees. Therefore,

∠QRP + ∠QPR + ∠PRQ = 180 degrees

Since ∠PRQ is a right angle (90 degrees), we have:

∠QRP + ∠QPR = 90 degrees

Now, we are given that ∠QPR is 25 degrees. Substituting this in the above equation, we get:

∠QRP + 25 = 90 degrees

Solving for ∠QRP, we get:

∠QRP = 90 - 25 = 65 degrees

Therefore, the measure of angle R is 65 degrees, which is option (D).

What is expressiοn ?

An expressive in mathematics is a collection of numbers, variables, and complicated mathematical operations (such as addition, subtraction, multiplication, division, multiplicands, and others) that convey a quantity's value. Expressions can be as straightforward as "3 + 4" or as complex as "(3x2 - 2) / (x + 1)". They could also include functions like "sin(x)" or "lg(y)".

The real way to evaluate an expression is to insert the variables with their values and carry out the arithmetic operations in the order specified. For instance, the phrase "3x + 5" means 3(2) + 5 = 11 if x = 2. In mathematics, expressions are typically used to describe actual situations, build equations, and decompose challenging mathematical diagrams.

The shape of the resultant matrix of the multiplication of a "2 by 4" matrix and a "4 by 3" matrix will be a "2 by 3" matrix, the correct option is (d).

We know that the general rule for matrix multiplication, which is If matrix A is "m by n" matrix (it has m rows and n columns) and the matrix B is "n by k" matrix (it has n rows and k columns),

Then the product AB is an "m by k" matrix, which means, that the resulting matrix will have "m" rows and "k" columns.

In this case, the "2 by 4" matrix means that matrix has 2-rows and 4-columns, and

The "4 by 3" matrix means the matrix has 4-rows and 3-columns.

Since the number of columns in the first matrix (4) matches the number of rows in the second matrix (4), we can perform the multiplication.

The resulting matrix will have 2 rows and 3 columns,

Therefore, the shape of the resultant matrix is (d) 2 by 3.

Answers

The percent abundance of medium nails in the sample is approximately 18.95%.

What is weighted averaging?

An average value for a collection of data is calculated statistically via weighted averaging, where each data point is assigned a weight based on its relative relevance or frequency. This method is frequently applied when certain data points are more important than others or when the sample sizes for several sets of data vary. Each data point is multiplied by its weight in weighted averaging, and the resulting products are added up and divided by the overall weight.

The number of each type of nail is:

Abundance = 67 + 18 + 10 = 95

The weighted average is:

Weighted Average = (Abundance1 x Value1 + Abundance2 x Value2 + ... + AbundanceN x ValueN) / Total Abundance

For different types of nails we have:

Short nail: Abundance1 = 67, Value1 = 2.5

Medium nail: Abundance2 = 18, Value2 = 5.0

Long nail: Abundance3 = 10, Value3 = 7.5

Substituting the values:

Weighted Average = (67 x 2.5 + 18 x 5.0 + 10 x 7.5) / 95

Weighted Average ≈ 3.53

The percent abundance is:

Percent Abundance = (Abundance2 / Total Abundance) x 100%

Substituting the values:

Percent Abundance = (18 / 95) x 100%

Percent Abundance ≈ 18.95%

Hence, the percent abundance of medium nails in the sample is approximately 18.95%.

The retail price of a television set is $4,500. If the buyer pays by cash, the price is 10% below the retail price. If the set is bought on higher purchase, the buyer pays a down payment of $675 and 24 monthly installments of $212.50. Calculate for the television the:

cash price to the buyer, if he pays by cash.
amount payable.
outstanding balance.
hire purchase price.
interest.
difference between the hire purchase and the cash price.
percentage interest charged.

Answers

Cash price to the buyer, if he pays by cash:

The cash price would be 10% less than the retail price of $4,500:

Cash price = $4,500 - (10% * $4,500)

Cash price = $4,500 - $450

Cash price = $4,050

Amount payable:

If the buyer chooses to purchase the TV on higher purchase, the amount payable would be the sum of the down payment and the total amount of monthly installments:

Amount payable = Down payment + (24 * Monthly installment)

Amount payable = $675 + (24 * $212.50)

Amount payable = $5,175

Outstanding balance:

The outstanding balance would be the difference between the amount payable and the down payment:

Outstanding balance = Amount payable - Down payment

Outstanding balance = $5,175 - $675

Outstanding balance = $4,500

Hire purchase price:

The hire purchase price would be the sum of the down payment and the outstanding balance:

Hire purchase price = Down payment + Outstanding balance

Hire purchase price = $675 + $4,500

Hire purchase price = $5,175

Interest:

The interest charged on the hire purchase would be the difference between the hire purchase price and the cash price:

Interest = Hire purchase price - Cash price

Interest = $5,175 - $4,050

Interest = $1,125

Difference between the hire purchase and the cash price:

The difference between the hire purchase price and the cash price would be the interest charged:

Difference = Interest

Difference = $1,125

Percentage interest charged:

To calculate the percentage interest charged, we can divide the interest by the hire purchase price and multiply by 100:

Percentage interest charged = (Interest / Hire purchase price) * 100

Percentage interest charged = ($1,125 / $5,175) * 100

Percentage interest charged = 21.74%

Therefore, the cash price to the buyer is $4,050, the amount payable is $5,175, the outstanding balance is $4,500, the hire purchase price is $5,175, the interest charged is $1,125, the difference between the hire purchase and the cash price is $1,125, and the percentage interest charged is 21.74%.

Answer:

x = 0

Step-by-step explanation:

4x+4 = 4

Subtract 4 from both sides:-

4x+4-4 = 4-4

4x = 0

Divide both sides by 4:-

4x/4 = 0/4

Suppose that your mass is 86 kg How fast (in m/s) would vou have t0 run to have the same linear momentum as 1490 kg car moving at 2.7 km/h? Number Azo Units mfs The number of _ significant digits is set to 2; the tolerance is +/-3%/

Answers

The velocity with which we have to move to have the momentum equal to the car is 46.78 km/h.

Linear momentum is the vector quantity and described as the product of the mass of an object, m, and its velocity, v. It is represented by the symbol "p," which is also used to denote momentum. Please be aware that the body's momentum always points in the same direction as its vector of motion.

We are given:-

The mass of the car (M1) = 1490kg.

The velocity of the car (V1V1)= 2.7 km/h.

The formula to calculate linear momentum:- linear momentum= mass of the body* Velocity of the body (P= mvmv)

therefore, the momentum (P1) of the car = M1V1

P1= 1490*2.7= 4023

let momentum of yourself is P2 which is equal to P1 according to the question, Hence P2= 4023.

M2= 86 kg.

V2= ?

P2= M2V2

V2= P2/M2
V2 = 4023/86

V2= 46.78 km/h.

hhence toto the velocity with which we have to run to get momentum equal to the car is 46.78 km/h.

Locate the absolute extrema of the function on the closed interval

Answers

Answer:

The absolute extrema is minimum at (-1, 2/9)

Step-by-step explanation:

Absolute extrema is a logical point that shows whether a the curve function is maximum or minimum.

Forexample a curve in the image attached. A, B and C are points of absolute maxima or absolute maximum. and P and Q are points of absolute minima or minimum.

Remember A, B, C, P, Q are critical points or stationary points.

How do we find absolute extrema?

The find the sign of the second derivative of the function.

From the question;

[tex]{ \sf{g(x) = \sqrt[3]{x} }} \\ \\ { \sf{g(x) = {x}^{ \frac{1}{3} } }} \\ [/tex]

Find the first derivative of g(x)

[tex]{ \sf{g {}^{l}(x) = \frac{1}{3} {x}^{ - \frac{2}{3} } }} \\ [/tex]

Find the second derivative;

[tex]{ \sf{g {}^{ll} (x) = ( \frac{1}{3} \times - \frac{2}{3}) {x}^{( - \frac{2}{3} - 1) } }} \\ \\ { \sf{g {ll}^{(x)} = - \frac{2}{9} {x}^{ - \frac{5}{3} } }}[/tex]

Then substitute for x as -1 from [-1, 1]

[tex]{ \sf{g {}^{ll}(x) = - \frac{2}{9} ( - 1) {}^{ - \frac{5}{3} } }} \\ \\ = \frac{ - 2}{9} \times - 1 \\ \\ = \frac{2}{9} [/tex]

Since the sign of the result is positive, the absolute extrema is minimum

In a certain company, employees contribute to a welfare fund at the rate of 4% of the first $1000 earned, 3% of the next $1000, 2% of the next $1000 and 1% of any extra monies. How much will an employee who earned $20,000 contribute to the fund?​

Answers

The employee will contribute 4% of the first $1000, which is $40. Then, the employee will contribute 3% of the next $1000, which is $30. Following that, the employee will contribute 2% of the next $1000, which is $20. Finally, the employee will contribute 1% of the remaining $17,000, which is $170. Therefore, the employee will contribute a total of $260 to the fund.

An employee who earned $20,000 will contribute $260 to the welfare fund.

To calculate the contribution to the welfare fund for an employee who earned $20,000, we can break down the earnings into different tiers based on the given rates.

The first $1000 will have a contribution rate of 4%.

Contribution for the first $1000 = 4% of $1000 = $40.

The next $1000 will have a contribution rate of 3%.

Contribution for the next $1000 = 3% of $1000 = $30.

The next $1000 will have a contribution rate of 2%.

Contribution for the next $1000 = 2% of $1000 = $20.

The remaining amount above $3000 ($20,000 - $3000 = $17,000) will have a contribution rate of 1%.

Contribution for the remaining amount = 1% of $17,000 = $170.

Now, let's sum up the contributions for each tier:

$40 + $30 + $20 + $170 = $260.

Therefore, an employee who earned $20,000 will contribute $260 to the welfare fund.

A simple random sample of size n is drawn. The sample mean, x, is found to be 18.1, and the sample standard deviation, s, is found to be 4.1.

(a) Construct a 95% confidence interval about u if the sample size, n, is 34.

Answers

In response to the stated question, we may state that Hence, the 95% CI function for u is (16.72, 19.48), rounded to two decimal places in increasing order.

what is function?

In mathematics, a function is a connection between two sets of numbers in which each member of the first set (known as the domain) corresponds to a single element in the second set (called the range). In other words, a function takes inputs from one set and produces outputs from another. Inputs are commonly represented by the variable x, whereas outputs are represented by the variable y. A function can be described using an equation or a graph. The equation y = 2x + 1 represents a linear function in which each value of x yields a distinct value of y.v

We use the following formula to create a confidence interval around the population mean u:

CI = x ± z*(s/√n)

where x represents the sample mean, s represents the sample standard deviation, n represents the sample size, z represents the z-score associated with the desired degree of confidence, and CI represents the confidence interval.

Because the degree of confidence is 95%, we must calculate the z-score that corresponds to the standard normal distribution's middle 95%. This is roughly 1.96 and may be determined with a z-table or calculator.

CI = 18.1 ± 1.96*(4.1/√34)

CI = 18.1 ± 1.96*(0.704)

CI = 18.1 ± 1.38

Hence, the 95% CI for u is (16.72, 19.48), rounded to two decimal places in increasing order.

We are working on a survey that shows what 100 insurance holders claim for that survey. We find that 40 are fire claims (FIRE), 16 of which are fraudulent (FRAUD). Also, there are a total of 40 fraudulent claims.
(a) Let us construct a contingency table summarizing the claims data. Use the pairs of Events FIRE and FIRE, FRAUD and FRAUD as shown below:

Answers

The probability of a claim being both fire and fraudulent is:

P(Fire and Fraud) = number of claims that are both fire and fraudulent/total number of claims

= 16 / 100

= 0.16

We can use the information given to construct a contingency table as follows:

Fraud No Fraud Total

Fire 16 24 40

No Fire 24 36 60

Total 40 60 100

This table shows the number of insurance claims that fall under each combination of the FIRE and FRAUD events. For example, 16 claims are both fire and fraudulent, and 24 claims are fire but not fraudulent.

We can also calculate some probabilities from this table. For example, the probability of a claim being fraudulent is:

P(Fraud) = number of fraudulent claims / total number of claims

= 40 / 100

= 0.4

The equation of the line in slope-intercept form is y = 2.5x + 210.

What is slope intercept form?

y = mx + b, where m is the line's slope and b is its y-intercept, is the equation of a line in slope-intercept form. This version of the equation is advantageous since it makes it simple to determine a line's slope and y-intercept and to utilise its equation to graph the line.

We may first apply the formula for the slope to get the slope of the line in order to calculate the equation of a line given two points. Next, we solve for the y-intercept using the slope-intercept version of the problem, substituting the slope and one of the supplied locations.

The given coordinates of the line are (46, 325) and (64, 370).

The slope is given by:

m = (y2 - y1) / (x2 - x1)

Substituting the values we have:

m = (370 - 325) / (64 - 46)

m = 45 / 18

m = 2.5

The slope intercept form of the line is given as:

y = mx + b

here, b is the y-intercept.

325 = 2.5(46) + b

b = 325 - 115

b = 210

Hence, the equation of the line in slope-intercept form is y = 2.5x + 210.
