To find out how many hours Elmer will have to work to pay for the new bike, we first need to know the total cost of the bike, which is $90 according to the previous question.

Elmer earns $12 per hour. So, we can calculate the total hours he would need to work by dividing the total cost of the bike by his hourly wage.

Total hours = Total cost / Hourly wage = $90 / $12 = 7.5 hours

Therefore, Elmer will have to work for 7.5 hours to pay for the new bike.

Answer:$364

Step-by-step explanation:

To find the number of cubic feet in this cylinder, we would need to find the volume by multiplying the height in feet of the cylinder by pi by the radius squared.

30 x pi x 0.5^2 = 23.56 cubic feet

since our height is given to us as 30, and the diameter is 1, we know our radius is 0.5.

After that, we simply multiply the charge per cubic foot ($15.45) by the number we got for volume (23.56)

$15.45 x 23.56 = $364.002 which rounded to the nearest cent = $364

The approximate price of a 12oz box of Kellogg's Corn Flakes in 2008, with an initial price of $0.89 in 1984 and two subsequent increases of 235% and 105%, would be approximately $6.12

To calculate the price of a 12oz box of Kellogg's Corn Flakes in 2008, considering an increase of 235% and an additional increase of 105% from the initial price in 1984, we can follow these steps:

Step 1: Calculate the first increase of 235%:

First, we need to find the price after the first increase. To do this, we multiply the initial price in 1984 by 235% and add it to the initial price:

First increase = $0.89 * (235/100) = $2.09315

New price after the first increase = $0.89 + $2.09315 = $2.98315 (rounded to 5 decimal places)

Step 2: Calculate the additional increase of 105%:

Next, we need to calculate the second increase based on the price after the first increase. To do this, we multiply the price after the first increase by 105% and add it to the price:

Second increase = $2.98315 * (105/100) = $3.13231

New price after the additional increase = $2.98315 + $3.13231 = $6.11546 (rounded to 5 decimal places)

Therefore, the approximate price of a 12oz box of Kellogg's Corn Flakes in 2008, with an initial price of $0.89 in 1984 and two subsequent increases of 235% and 105%, would be approximately $6.12.

The determinant or det(2ATB^(-1)) is = 96.

Given that A and B are 3 by 3 matrices with det(A) = 3 and det(B) = -2, we want to find det(2ATB^(-1)).

Using the formula for the determinant of the product of two matrices, det(AB) = det(A)det(B), we can solve for det(2ATB^(-1)) as follows:

det(2ATB^(-1)) = det(2)det(A)det(B^(-1))det(T)det(B)

Since det(2) = 2^3 = 8, det(A) = 3, and det(B) = -2, we can substitute these values into the formula:

det(2ATB^(-1)) = 8 * 3 * det(B^(-1)) * det(T) * (-2)

To calculate det(B^(-1)), we know that det(B^(-1)) * det(B) = I, where I is the identity matrix:

det(B^(-1)) * det(B) = I

det(B^(-1)) * (-2) = 1

det(B^(-1)) = -1/2

Now, let's substitute this value back into the formula:

det(2ATB^(-1)) = 8 * 3 * (-1/2) * det(T) * (-2)

Since det(T) is the determinant of the transpose of a matrix, it is equal to the determinant of the original matrix:

det(2ATB^(-1)) = 8 * 3 * (-1/2) * det(B) * (-2)

Simplifying further:

det(2ATB^(-1)) = 8 * 3 * (-1/2) * (-2) * (-2)

= 8 * 3 * 1 * 4

= 96

Therefore, det(2ATB^(-1)) = 96.

given that it leaves remainders of -110 when divided by x+2 and 13 when divided by x-1. Additionally, the remainder when dividing the expression by 3x+2 needs to be determined.

i. The values of a and b are determined to be a = 3 and b = -4, respectively.

ii. The remainder when the expression is divided by 3x + 2 is 2.

i. To find the values of a and b, we utilize the remainder theorem. When the expression is divided by x + 2, we substitute x = -2 into the expression and set it equal to the remainder, which is -110. This gives us the equation: -8a - 4b + 2C - 4 = -110.

Next, when the expression is divided by x - 1, we substitute x = 1 into the expression and set it equal to the remainder, which is 13. This gives us the equation: a - b + C + 2 = 13.

Solving the two equations simultaneously, we obtain a = 3 and b = -4.

ii. To find the remainder when the expression is divided by 3x + 2, we substitute x = -2/3 into the expression. Simplifying the expression, we find the remainder to be 2.

In summary, the values of a and b are a = 3 and b = -4, respectively. When the expression is divided by 3x + 2, the remainder is 2.

The solution is;

If a < b, then (a,b) ∩ Q ≠ ∅

To prove this statement, we need to show that if a is less than b, then the intersection of the open interval (a,b) and the set of rational numbers (Q) is not empty.

Let's consider a scenario where a is a rational number and b is an irrational number. Since the set of rational numbers (Q) is dense in the set of real numbers, there exists a rational number r between a and b. Therefore, r belongs to the open interval (a,b), and we have (a,b) ∩ Q ≠ ∅.

On the other hand, if both a and b are rational numbers, then we can find a rational number q that lies between a and b. Again, q belongs to the open interval (a,b), and we have (a,b) ∩ Q ≠ ∅.

In both cases, whether a and b are rational or one of them is irrational, we can always find a rational number within the open interval (a,b), leading to a non-empty intersection with the set of rational numbers (Q).

This result follows from the density of rational numbers in the real number line. It states that between any two distinct real numbers, we can always find a rational number. Therefore, the intersection of the open interval (a,b) and the set of rational numbers (Q) is guaranteed to be non-empty if a < b.

b) It will take approximately 24.6 years to save $3,000 for your vacation by saving $100 each month with a 3% nominal interest rate compounded monthly.

c) equivalent effective interest rates are:

i. Semi-annually: 5.06%

ii. Quarterly: 5.11%

iii. Daily: 5.13%

iv. Continuously: 5.13%

EXPLANATION:

To calculate the time it will take for you to save $3,000 for your vacation, we can use the future value formula for monthly compounding:

[tex]Future Value = Principal * (1 + rate/n)^(n*time)[/tex]

Where:

- Principal is the amount you save each month ($100)

- Rate is the nominal interest rate (3% or 0.03)

- n is the number of compounding periods per year (12 for monthly compounding)

- Time is the number of years we want to calculate

We need to solve for time. Let's substitute the given values into the formula:

[tex]$3,000 = $100 * (1 + 0.03/12)^(12*time)Dividing both sides of the equation by $100:30 = (1.0025)^(12*time)[/tex]

Taking the natural logarithm (ln) of both sides:

[tex]ln(30) = ln((1.0025)^(12*time))Using logarithmic properties (ln(a^b) = b * ln(a)):ln(30) = 12*time * ln(1.0025)[/tex]

Solving for time:

[tex]time = ln(30) / (12 * ln(1.0025))[/tex]

Using a calculator:

time ≈ 24.6

c)To calculate the equivalent effective interest rate for a nominal rate of 5% compounded at different intervals:

i. Semi-annually:

The effective interest rate for semi-annual compounding is calculated using the formula:

Effective Interest Rate = (1 + (nominal rate / number of compounding periods))^number of compounding periods - 1

For semi-annual compounding:

[tex]Effective Interest Rate = (1 + (0.05 / 2))^2 - 1[/tex]

Calculating:

Effective Interest Rate ≈ 0.050625 or 5.06%

ii. Quarterly:

The effective interest rate for quarterly compounding is calculated similarly:

[tex]Effective Interest Rate = (1 + (0.05 / 4))^4 - 1[/tex]

Calculating:

Effective Interest Rate ≈ 0.051136 or 5.11%

iii. Daily:

The effective interest rate for daily compounding is calculated using the formula:

Effective Interest Rate = (1 + (nominal rate / number of compounding periods))^number of compounding periods - 1

Since there are approximately 365 days in a year:

[tex]Effective Interest Rate = (1 + (0.05 / 365))^365 - 1[/tex]

Calculating:

Effective Interest Rate ≈ 0.051267 or 5.13%

iv. Continuously:

The effective interest rate for continuous compounding is calculated using the formula:

[tex]Effective Interest Rate = e^(nominal rate) - 1[/tex]

The derivative of y = tan(5x - 4) is 5sec^2(5x - 4). This can be found using the chain rule, where dy/dx = dy/du * du/dx, and substituting the derivative of the tangent function and simplifying.

To find dy/dx for y = tan(5x - 4), we can use the chain rule. Let u = 5x - 4, so that y = tan(u). Then, by the chain rule,

dy/dx = dy/du * du/dx

To find du/dx, we can take the derivative of u with respect to x:

du/dx = 5

To find dy/du, we can use the derivative of tangent function:

dy/du = sec^2(u)

Substituting these values back into the chain rule equation, we get:

dy/dx = dy/du * du/dx = sec^2(u) * 5

Substituting back u = 5x - 4 and using the identity sec^2(x) = 1/cos^2(x), we get:

dy/dx = 5/cos^2(5x - 4)

The new ratio of the siblings' share of sweets is 19:28:25. Thus, option A is correct..

Initially, the siblings shared the 42 chocolate sweets according to the ratio 3:6:5.

To find the total number of parts in the ratio, we add the individual ratios: 3 + 6 + 5 = 14 parts.

To determine the share of each sibling, we divide the total number of sweets (42) into 14 parts:

Trust's share = (3/14) * 42 = 9 sweets

Hardlife's share = (6/14) * 42 = 18 sweets

Innocent's share = (5/14) * 42 = 15 sweets

The phrase "cocktail party effect" describes how the brain may choose concentrate on one discussion while in a noisy setting, such as a packed party. It allows people to tune out unimportant sounds and focus on important auditory information.

Due to the presence of arrowheads or fins at the ends of two lines of equal length, the Müller-Lyer illusion causes the lines to appear to be different. In contrast to the line with inward-pointing fins, the line with outward-pointing fins appears longer.

The cocktail party effect highlights our ability to focus on a specific sound amidst noise, while the dynamic Müller-Lyer illusion and the Ponzo illusion demonstrate how our visual perception can be influenced by contextual cues and depth cues, leading to misjudgments of size and distance.

The cocktail party effect occurs when individuals can effectively tune in to a specific conversation or sound amidst a noisy background. It is a remarkable ability of the human auditory system to filter out irrelevant stimuli and focus on the desired information.

This phenomenon allows us to follow a single conversation at a crowded social event, like a cocktail party, while ignoring other conversations and background noise.

The dynamic Müller-Lyer illusion is a visual illusion where two lines of equal length appear to be different due to the addition of arrow-like figures at their ends.

One line with outward-pointing arrows seems longer than the other line with inward-pointing arrows. This illusion demonstrates how our perception can be influenced by contextual cues and suggests that our brain interprets the length of a line based on the surrounding visual information.

The Ponzo illusion is another visual illusion that deceives our perception of size and distance. It involves two identical horizontal lines placed between converging lines that create the illusion that one line is larger than the other.

This illusion occurs because our brain interprets the size of an object based on the surrounding context. The converging lines give the impression that one line is farther away, and according to depth cues, objects farther away should appear larger.

The cocktail party effect refers to the phenomenon where individuals can selectively focus their attention on a specific conversation or sound in a noisy environment.

a. To evaluate the integral ∫S z²dz, where S is the line segment from 0 to -1+2i sin(22)dz:

We need to parameterize the line segment S. Let's parameterize it by t from 0 to 1:

a) The selling price of the sound bar = $900

Trade discount series = 29%, 16.5%, 2% (Successive discounts)

Formula used: Net price formula = List price - Discount List price

= Net price / (100% - Rate of discount)

Amount of discount = List price × (Rate of discount / 100%)

Single equivalent discount formula  = (Total discount / Original price) × 100%

Calculate the list price using the net price formula,

List price = Net price / (100% - Rate of discount)

List price after 1st discount = $900 × (100% - 29%) = $639

List price after 2nd discount = $639 × (100% - 16.5%) = $533.14

List price after 3rd discount = $533.14 × (100% - 2%)

= $522.48

Therefore, the net price of the sound bar is $522.48.

b) The amount of discount = List price × (Rate of discount / 100%)

Amount of discount after 1st discount = $900 × (29% / 100%) = $261

Amount of discount after 2nd discount = $639 × (16.5% / 100%)

Answer: A

Step-by-step explanation:

The amount of the additional discount Maycon received is $23.0625 - $20.50 = $2.5625.

To find the amount of the additional discount Maycon received, we first need to calculate the price of the shirt after applying the 25% coupon discount.

The original price of the shirt is $30.75. After applying the 25% off coupon, Maycon would get a discount of 25% of $30.75, which is 0.25 * $30.75 = $7.6875.

So, the price of the shirt after the coupon discount would be $30.75 - $7.6875 = $23.0625.

Now, we know that the final price of the shirt, after both the coupon discount and the additional discount, is $20.50.

The given non-homogeneous problem is a second-order linear differential equation with variable coefficients. To find the general solution, we first solve the corresponding homogeneous problem by setting the right-hand side to zero.

The auxiliary equation is obtained by replacing the derivatives with the characteristic equation: r^2 - 6r + 10 = 0. Solving this quadratic equation gives us the roots 3+1 and 3-i.

From these roots, we find a fundamental set of solutions using the formulas e^(ax)cos(bx) and e^(ax)sin(bx).

Thus, the complementary solution is C1e^(3x)cos(x) + C2e^(3x)sin(x), where C1 and C2 are arbitrary constants.

To determine a particular solution, we use the method of undetermined coefficients.

We assume a solution of the form yp = Acos(2x) + Bsin(2x) and find the values of A and B by substituting this into the non-homogeneous equation and comparing coefficients.

The general solution is then given by the sum of the complementary and particular solutions: y = C1e^(3x)cos(x) + C2e^(3x)sin(x) + 24cos(2x) + 12sin(2x).

To solve the IVP, we substitute the initial conditions y(0) = 25 and y'(0) = 26 into the general solution and solve for the values of the arbitrary constants C1 and C2, resulting in the unique solution.

If a media planner wishes to run 120 adult 18-34 GRPS per week, the frequency of the advertisement needs to be 3 times per week.

The Gross Rating Point (GRP) is a metric that is used in advertising to measure the size of an advertiser's audience reach. It is measured by multiplying the percentage of the target audience reached by the number of impressions delivered. In other words, it is a calculation of how many people in a specific demographic will be exposed to an advertisement. For instance, if the GRP of a particular ad is 100, it means that the ad was seen by 100% of the target audience.

Frequency is the number of times an ad is aired on television or radio, and it is an essential aspect of media planning. A frequency of three times per week is ideal for an advertisement to have a significant impact on the audience. However, it is worth noting that the actual frequency needed to reach a specific audience may differ based on the demographic and the product or service being advertised.

To find the probability P(greater than 16) of drawing a card numbered greater than 16 from a hat containing cards numbered 1 through 28, we need to determine the number of favorable outcomes (cards greater than 16) and divide it by the total number of possible outcomes (all the cards).

P(greater than 16) = Number of favorable outcomes / Total number of possible outcomes

To calculate the number of favorable outcomes, we need to determine the number of cards numbered greater than 16. There are 28 cards in total, so the favorable outcomes would be the cards numbered 17, 18, 19, ..., 28. Since there are 28 cards in total, and the numbers range from 1 to 28, the number of favorable outcomes is 28 - 16 = 12.

To find the total number of possible outcomes, we consider all the cards in the hat, which is 28.

Now we can calculate the probability:

P(greater than 16) = Number of favorable outcomes / Total number of possible outcomes

P(greater than 16) = 12 / 28

Simplifying this fraction, we can reduce it to its simplest form:

P(greater than 16) = 6 / 14

P(greater than 16) = 3 / 7

Therefore, the probability of drawing a card numbered greater than 16 is 3/7 or approximately 0.4286 (rounded to four decimal places).

In summary, the probability P(greater than 16) is determined by dividing the number of favorable outcomes (cards numbered greater than 16) by the total number of possible outcomes (all the cards). In this case, there are 12 favorable outcomes (cards numbered 17 to 28) and a total of 28 possible outcomes (cards numbered 1 to 28), resulting in a probability of 3/7 or approximately 0.4286.

The minimal cost for the optimal order quantity, Q*, for Consumed by Kaffein (CBK) is $X. The ordering and holding costs per year will be Y% of the annual purchase cost for the coffee beans.

To determine the minimal cost for the optimal order quantity, we need to consider both the ordering and holding costs. The ordering cost consists of a fixed cost of $100 per delivery, independent of the order size. The holding cost is incurred for carrying inventory and is given as 20% per year.

First, we calculate the optimal order quantity, Q*, which minimizes the total cost. This can be done using the economic order quantity (EOQ) formula:

EOQ = √((2DS) / H),

where D is the annual demand (60 bags), S is the cost per order ($100), and H is the holding cost per unit ($30 * 20% = $6 per bag).

Plugging in the values, we get:

EOQ = √((2 * 60 * 100) / 6) ≈ 55.9 bags.

Next, we calculate the minimal cost, C(Q*), for the optimal order quantity. It consists of both the ordering cost and the holding cost. The ordering cost can be calculated by dividing the annual demand (60 bags) by the optimal order quantity (55.9 bags) and multiplying it by the cost per order ($100):

Ordering cost = (60 / 55.9) * $100 ≈ $107.36.

The holding cost can be calculated by multiplying the optimal order quantity (55.9 bags) by the holding cost per unit ($6 per bag):

Holding cost = 55.9 * $6 = $335.40.

The total minimal cost, C(Q*), is the sum of the ordering cost and the holding cost:

C(Q*) = $107.36 + $335.40 = $442.76.

Finally, we calculate the ordering and holding costs per year as a percentage of the annual purchase cost for the coffee beans. The annual purchase cost for the coffee beans is given by the number of bags (60) multiplied by the cost per bag ($30):

Annual purchase cost = 60 * $30 = $1800.

The ordering and holding costs per year can be calculated by dividing the total costs (ordering cost + holding cost) by the annual purchase cost and multiplying by 100:

Ordering and holding costs per year = ($442.76 / $1800) * 100 ≈ 24.6%.

Therefore, the minimal cost for the optimal order quantity, Q*, for CBK is $442.76, and the ordering and holding costs per year will be approximately 24.6% of the annual purchase cost for the coffee beans.

a. The total amount of money deposited in the bank as a result of these transactions is $3333.33.

b. The credit multiplier for this example is 33.33.

a. The total amount of money deposited in the bank as a result of these transactions can be found by summing up the amounts loaned out and eventually redeposited.

Starting with the original deposit of $100, 97% of it, which is $97, is loaned out. This $97 is then redeposited in the bank.

From this redeposited amount, 97% is loaned out again, which is $97(0.97) = $94.09. This $94.09 is also redeposited in the bank.

Continuing this process, we can find the total amount of money deposited in the bank.

After multiple rounds of lending and redepositing, we can observe that each new round decreases by 3%.

To calculate the total amount of money deposited, we can use the formula for the sum of a geometric series:

Total amount deposited = original deposit + (original deposit * lending percentage) + (original deposit * lending percentage^2) + ...

In this case, the original deposit is $100, and the lending percentage is 97% or 0.97.

Using the formula, we can find the total amount of money deposited by summing up each round:

$100 + $97 + $94.09 + ...

This is an infinite geometric series, and the sum of an infinite geometric series is given by:

Sum = a / (1 - r)

Where "a" is the first term and "r" is the common ratio.

In this case, "a" is $100 and "r" is 0.97.

Plugging in these values into the formula, we get:

Total amount deposited = $100 / (1 - 0.97)

Total amount deposited = $100 / 0.03

Total amount deposited = $3333.33 (rounded to 2 decimal places)

Therefore, the total amount of money deposited in the bank as a result of these transactions is $3333.33.

b. Now let's calculate the credit multiplier for this example.

The credit multiplier is the ratio of the total amount of money deposited to the original deposit.

Credit multiplier = Total amount deposited / Original deposit

Credit multiplier = $3333.33 / $100

Credit multiplier = 33.33 (rounded to 2 decimal places)

Therefore, the credit multiplier for this example is 33.33.

The area of the region bounded by the curves y = √x, x = 4 - y², and the x-axis is 1/6 square units.

To find the area of the region bounded by the curves y = √x, x = 4 - y², and the x-axis, we can set up the integral as follows:

A = ∫[a,b] (f(x) - g(x)) dx

where f(x) is the upper curve and g(x) is the lower curve.

In this case, the upper curve is y = √x and the lower curve is x = 4 - y².

To find the limits of integration, we set the two curves equal to each other:

√x = 4 - y²

Solving for y, we get:

y = ±√(4 - x)

To find the limits of integration, we need to determine the x-values at which the curves intersect.

Setting √x = 4 - y², we have:

x = (4 - y²)²

Substituting y = ±√(4 - x), we get:

x = (4 - (√(4 - x))²)²

Expanding and simplifying, we have:

x = (4 - (4 - x))²

x = x²

This gives us x = 0 and x = 1 as the x-values of intersection.

So, the limits of integration are a = 0 and b = 1.

Now, we can calculate the area using the integral:

A = ∫[0,1] (√x - (4 - y²)) dx

To simplify the integral, we need to express (4 - y²) in terms of x.

From the equation y = ±√(4 - x), we can solve for y²:

y² = 4 - x

Substituting this into the integral, we have:

A = ∫[0,1] (√x - (4 - 4 + x)) dx

A = ∫[0,1] (√x - x) dx

Integrating, we get:

A = [(2/3)x^(3/2) - (1/2)x²] evaluated from 0 to 1

A = (2/3 - 1/2) - (0 - 0)

A = 1/6

Therefore, the area of the region bounded by the curves y = √x, x = 4 - y², and the x-axis is 1/6 square units.
