The composite function has its value to be 54168

From the question, we have the following parameters that can be used in our computation:

f(x)=10x^2-8x

g(x)=7x-3.

Given the composite function [f o g] (11)., we have

[f o g] (11) = f(g(11))

Substitute the known values in the above equation, so, we have the following representation

g(11) =7 * 11 - 3

Evaluate

g(11) =74

So, we have

[f o g] (11) = f(74)

[f o g] (11) = 10(74)^2 - 8(74)

[f o g] (11) = 54168

Hence, the solution is 54168

Answer:

≅20.9%

Step-by-step explanation:

To find the percent decrease, we need to calculate the difference between the old value (349) and the new value (276), divide that by the old value, and then multiply by 100 to express it as a percentage.

The formula for percent decrease is:

percent decrease = ((old value - new value) / old value) x 100%

Substituting the given values, we get:

percent decrease = ((349 - 276) / 349) x 100%

percent decrease = (73 / 349) x 100%

percent decrease = 20.92%

Rounding to the nearest tenth of a percent, we get:

percent decrease ≈ 20.9%

Therefore, the percent decrease in the number of petty crimes this year is [approximately 20.9%.]

The probabilities are given as follows:

1) Blue eyes: 0.132.

2) Female with green eyes: 0.09.

20 + 25 + 30 + 15 + 10 + 12 + 15 + 20 + 10 + 10 = 167.

10 + 12 = 22 people out of 167 have blue eyes, hence the probability is given as follows:

p = 22/167 = 0.132.

15 people out of 167 are female with green eyes, hence the probability is given as follows:

Answer:

Step-by-step explanation:

a) To find the probability that Mateo will die in his 60th year, we use the value of the probability distribution given in the problem statement: P(x=60) = 0.01051.

To calculate the expected cost to Big Rock Insurance if Mateo dies in his 60th year, we multiply the death benefit of $50,000 by the probability of death:

Expected cost = P(x=60) * $50,000 = 0.01051 * $50,000 = $525.50.

So the expected cost to Big Rock Insurance if Mateo dies in his 60th year is $525.50.

b) To find the probabilities that Mateo will die in years 61, 62, 63, and 64, we use the values of the probability distribution given in the problem statement: P(x=61) = 0.01477, P(x=62) = 0.01744, P(x=63) = 0.02035, and P(x=64) = 0.02227.

To calculate the expected cost to Big Rock Insurance if Mateo dies in each of these years, we multiply the death benefit of $50,000 by the corresponding probability of death:

Expected cost if Mateo dies in his 61st year = P(x=61) * $50,000 = 0.01477 * $50,000 = $738.50.

Expected cost if Mateo dies in his 62nd year = P(x=62) * $50,000 = 0.01744 * $50,000 = $872.00.

Expected cost if Mateo dies in his 63rd year = P(x=63) * $50,000 = 0.02035 * $50,000 = $1017.50.

Expected cost if Mateo dies in his 64th year = P(x=64) * $50,000 = 0.02227 * $50,000 = $1113.50.

So the expected costs to Big Rock Insurance if Mateo dies in his 61st, 62nd, 63rd, and 64th years are $738.50, $872.00, $1017.50, and $1113.50, respectively.

c) To calculate the total expected cost to Big Rock Insurance over the years 60 through 64, we add up the expected costs for each year:

Total expected cost = Expected cost in year 60 + Expected cost in year 61 + Expected cost in year 62 + Expected cost in year 63 + Expected cost in year 64

Total expected cost = $525.50 + $738.50 + $872.00 + $1017.50 + $1113.50

Total expected cost = $4267.00

So the total expected cost to Big Rock Insurance over the years 60 through 64 is $4267.00.

d) If Big Rock Insurance wants to make a profit of $700 above the expected total cost payout for Mateo's death, it would need to charge a premium equal to the expected cost plus the desired profit:

Premium = Total expected cost + Desired profit

Premium = $4267.00 + $700.00

Premium = $4967.00

So Big Rock Insurance should charge a premium of $4967.00 for the policy if it wants to make a profit of $700 above the expected total cost payout for Mateo's death.

that in the second year, we use the beginning book value of $639,900

a. Sum-of-the-years’-digits method:

To compute the depreciation using the sum-of-the-years’-digits method, we first need to determine the total number of years of the asset's useful life. We do this by subtracting the salvage value from the cost and dividing by the estimated yearly depreciation.

Cost of asset = $711,000

Salvage value = $60,000

Useful life = 20 years

Yearly depreciation = (Cost - Salvage value) / Useful life

Yearly depreciation = ($711,000 - $60,000) / 20 = $32,550

To calculate the sum-of-the-years’-digits (SYD) for this asset, we add up the digits of the useful life in descending order. For a 20-year useful life, the SYD would be:

SYD = 20 + 19 + 18 + ... + 1 = 210

Using the SYD and the number of remaining years, we can calculate the depreciation expense for each year as follows:

Year 2020:

Depreciation expense = (20/210) x ($711,000 - $60,000) = $64,286

Year 2021:

Depreciation expense = (19/210) x ($711,000 - $60,000) = $60,952

b. Double-declining-balance method:

To compute the depreciation using the double-declining-balance (DDB) method, we first need to determine the asset's straight-line depreciation rate, which is calculated as follows:

Straight-line depreciation rate = 1 / Useful life

Straight-line depreciation rate = 1 / 20 = 0.05

The DDB depreciation rate is twice the straight-line rate, or 0.10. We can then calculate the depreciation expense for each year as follows:

Year 2020:

Depreciation expense = Beginning book value x DDB rate

Beginning book value = Cost of asset

Depreciation expense = $711,000 x 0.10 = $71,100

Year 2021:

Depreciation expense = Beginning book value x DDB rate

Beginning book value = Cost of asset - Accumulated depreciation from previous years

Accumulated depreciation (2020) = $71,100

Beginning book value (2021) = $711,000 - $71,100 = $639,900

Depreciation expense = $639,900 x 0.10 = $63,990

There are no numbers between 1.8×100 and 195%.

The representation of quantities or values using numbers is a fundamental idea in mathematics. They can be applied to measure, compare, compute, and count. Depending on the situation and the chosen notational system, numbers can be represented in a variety of ways, such as digits, words, or symbols.

Based on their attributes and traits, several sorts of numbers can be distinguished in mathematics. The following list includes some of the most typical numbers:

To identify the numbers between 1.8×100 and 195%, we need to convert both numbers to the same unit of measurement.

1.8×100 = 180

195% = 1.95 (since 195% is equal to 1.95 times the original quantity)

Now, we need to identify all numbers between 180 and 1.95. To do this, we can simply list all the numbers that are greater than 180 and less than 1.95, excluding 180 and 1.95 themselves. However, we notice that there are no such numbers, because:

Any number greater than 180 is also greater than 1.95 since 1.95 is less than 2 and 180 is greater than 2.

Any number less than 1.95 is also less than 180 since 180 is greater than 100 (which is 1% of 10,000) and 1.95 is less than 2.

Therefore, there are no numbers between 1.8×100 and 195%.

The solution to the matrix is x1 = (-555 - 356x3)/90, x2 = (138 + 89x3)/10 and x3 = free variable

To find the solution to this matrix, we need to perform row operations to put it into row echelon form or reduced row echelon form. We can do this by adding multiples of one row to another row, multiplying a row by a nonzero scalar, and swapping two rows.

Here are the row operations we can use to put this matrix into row echelon form:

1. Add 5 times the first row to the third row to eliminate the 5 in the (3,1) entry:

0 0 -9 6

0 -1 -4 4

25 35 11 38

2. Multiply the second row by -1 to make the pivot in the second row, second column equal to 1:

0 0 -9 6

0 1 4 -4

25 35 11 38

3. Add 9 times the second row to the first row to eliminate the -9 in the (1,3) entry:

0 9 0 -30

0 1 4 -4

25 35 11 38

4. Add -25 times the second row to the third row to eliminate the 25 in the (3,1) entry:

0 9 0 -30

0 1 4 -4

0 10 -89 138

5. This matrix is now in row echelon form. We can solve for the variables by back-substitution. Starting with the last row:

0 10 -89 138 | x3

We have:

10x2 - 89x3 = 138

Solving for x2, we get:

x2 = (138 + 89x3)/10

Substituting this expression for x2 in the second row, we have:

Copy code

0 1 4 -4 | (138 + 89x3)/10

Solving for x1, we get:

9x1 + 4(138 + 89x3)/10 = -30

Simplifying and solving for x1, we get:

x1 = (-555 - 356x3)/90

So the solution to the matrix is:

x1 = (-555 - 356x3)/90

x2 = (138 + 89x3)/10

Answer:

Step-by-step explanation:

To find the third year value of the deposit, we can use the formula for compound interest:

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

where A is the amount of money after t years, P is the principal (the initial deposit), r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.

For the first year, we have:

P = $500

r = 0.05

n = 1 (compounded annually)

t = 1

So, the amount after the first year is:

A1 = $500(1 + 0.05/1)^(1*1) = $525

For the second year, we have:

P = $525 (the amount after the first year)

r = 0.06

n = 1

t = 1

So, the amount after the second year is:

A2 = $525(1 + 0.06/1)^(1*1) = $556.50

For the third year, we have:

P = $556.50 (the amount after the second year)

r = 0.07

n = 1

t = 1

So, the amount after the third year is:

A3 = $556.50(1 + 0.07/1)^(1*1) = $594.64

Therefore, the third year value of the deposit is $594.64.

For the given percenatge of total cost, the total value of Gabe's health care coverage for the year is $9,984.

What is percentage?

Percentage is a way of expressing a fraction or a part of a whole as a portion out of 100. It is represented by the symbol "%".

We can start by using the information given to determine the total cost of the health care coverage. Let's call this cost "C". Since Gabe contributes 15% of this cost and pays $28.80 per week, we can write:

0.15C = 28.80

To solve for C, we can divide both sides by 0.15:

C = 28.80 / 0.15

= 192

So the total cost of the health care coverage is $192 per week. To find the total value of Gabe's health care coverage for the year, we need to multiply this weekly cost by the number of weeks in a year.

Assuming there are 52 weeks in a year, we have:

Total value of Gabe's health care coverage = 192 x 52

= 9984

Therefore, the total value of Gabe's health care coverage for the year is $9,984.

Answer:

Step-by-step explanation:

a. The average rate of change in the cost of the hamburger during the period from 2012 to 2022 can be calculated as the difference in the cost of the hamburger divided by the number of years between the two prices.

So, the average rate of change in the cost of the hamburger is:

(6.12 - 4.32) / (2022 - 2012) = 0.18

Therefore, the average rate of change in the cost of the hamburger during this period is $0.18 per year.

b. We can use the point-slope form of a linear equation to model the cost of the hamburger as it changes over time. Let y be the cost of the hamburger in dollars, and t be the number of years since 2012. We know that the cost of the hamburger in 2012 was $4.32, so we have a starting point of (0, 4.32).

Using the average rate of change calculated in part a, we can find the slope of the line:

slope = (6.12 - 4.32) / (2022 - 2012) = 0.18

Now we can write the equation of the line as:

y - 4.32 = 0.18t

y = 0.18t + 4.32

So, the linear equation that models the cost of the hamburger in terms of years since 2012 is y = 0.18t + 4.32.

c. To find when the cost of the hamburger will reach $7.02, we can substitute y = 7.02 into the equation we found in part b and solve for t:

7.02 = 0.18t + 4.32

2.7 = 0.18t

t = 15

So, the cost of the hamburger will reach $7.02 in the year 2012 + 15 = 2027.

The equation of rational function is f(x) = 3 - (5/2)(x - 5)(x + 1) / ((x + 2)(x + 6))

One possible equation for a rational function with the given properties is:

f(x) = 3 + (k(x + 5)(x - 5)) / ((x + 2)(x + 6))

Here, k is a constant that determines the vertical scale of the function. We choose the factor (x + 5)(x - 5) in the numerator to make the x-intercepts at x = 5 and x = -5. We choose the factors (x + 2) and (x + 6) in the denominator to make the vertical asymptotes at x = -2 and x = -6. We choose the constant term 3 in the equation to make the horizontal asymptote at y = 3.

To determine the value of k, we can use one of the x-intercepts, say x = 5. Substituting x = 5 into the equation and setting the result to 0 (since the function has an x-intercept at x = 5) gives:

0 = 3 + (k(5 + 5)(5 - 5)) / ((5 + 2)(5 + 6))

Simplifying the right-hand side, we get:

0 = 3 + 0 / (7 * 11)

0 = 3

This equation is not true, which means that we have made a mistake somewhere. The mistake is in assuming that the x-intercepts occur at x = 5 and x = -5. Instead, we should have x-intercepts at x = 5 and x = -1, which are the roots of the numerator (x - 5)(x + 1). So we need to adjust the numerator in the equation to (x - 5)(x + 1) in order to get the correct x-intercepts.

The correct equation for the rational function is:

f(x) = 3 + (k(x - 5)(x + 1)) / ((x + 2)(x + 6))

To determine the value of k, we can use the other x-intercept, x = -1. Substituting x = -1 into the equation and setting the result to 0 gives:

0 = 3 + (k(-1 - 5)(-1 + 1)) / ((-1 + 2)(-1 + 6))

Simplifying the right-hand side, we get:

0 = 3 + 6k / 5

Multiplying both sides by 5, we get:

0 = 15 + 6k

Solving for k, we get:

k = -15 / 6 = -5/2

So the final equation for the rational function is:

f(x) = 3 - (5/2)(x - 5)(x + 1) / ((x + 2)(x + 6))

Answer:

y- intercept = 7

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - 2 , then

y = - 2x + c ← is the partial equation

to find c substitute (4, - 1 ) into the partial equation

- 1 = - 2(4) + c = - 8 + c ( add 8 to both sides )

7 = c

that is the y- intercept = 7
