Answer:

f(2a + 3) = 8a² + 20a + 27

Step-by-step explanation:

f(x) = 2x² + 4x - 3

f(2a + 3) = 2(2a + 3)² + 4(2a + 3) - 3

f(2a + 3) = 8a² + 12a + 18 + 8a + 12 - 3

f(2a + 3) = 8a² + 20a + 27

The value of f(2a+3) for the given function f(x) = 2x² + 4x - 3 will be 8a² + 20a + 27.

A certain kind of relationship called a function binds inputs to essentially one output.

In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.

Given the function f(x) = 2x² + 4x - 3

⇒ f(2a + 3) = 2(2a + 3)² + 4(2a + 3) - 3

⇒ f(2a + 3) = 2(4a² + 9 + 6a) + 8a + 12 - 3

⇒ f(2a + 3) = 8a² + 18 + 12a + 8a + 12 - 3

⇒  f(2a + 3) = 8a² + 20a + 27.

Hence "The value of f(2a+3) for the given function f(x) = 2x² + 4x - 3 will be 8a² + 20a + 27".

the eigenvalues for the given boundary value problem are λ = 0 and λ = 1, and the corresponding eigenfunctions are y₁(x) = 1 and y₂(x) = \(x^{(1-\lambda)\).

To find the eigenvalues and eigenfunctions for the given boundary value problem, we can solve the differential equation and apply the boundary conditions.

First, let's rewrite the differential equation in standard form by dividing through by x²:

y'' + (1/x) y' + (λ/x²) y = 0

Now, let's assume the solution has the form y(x) = \(x^r\), where r is a constant to be determined. Substituting this into the differential equation:

\(x^r\) (r(r-1) + r + λ/x) = 0

Rearranging and simplifying:

r² + (λ - 1) r = 0

This is a quadratic equation for r. The solutions for r are:

r₁ = 0

r₂ = 1 - λ

These are the eigenvalues.

Next, we find the corresponding eigenfunctions for each eigenvalue by substituting the values of r back into the assumed form of the solution.

For r₁ = 0, the corresponding eigenfunction is y₁(x) = x⁰ = 1.

For r₂ = 1 - λ, the corresponding eigenfunction is y₂(x) = \(x^{(1-\lambda)\).

Therefore, the eigenvalues for the given boundary value problem are λ = 0 and λ = 1, and the corresponding eigenfunctions are y₁(x) = 1 and y₂(x) = \(x^{(1-\lambda)\).

Answer:

$33.60

Step-by-step explanation:

Original price of shirt: $40

Percent discount: 20%

Amount of discount: 20% of $40 = 0.2 × $40 = $8

Price after discount: $40 - $8 = $32

Percent of tax: 5%

Amount of tax: 5% of $32 = 0.05 × $32 = $1.60

Total paid after discount and tax: $32 + $1.60 = $33.60

Answer: Lydia paid the amount of 33.60 dollar

Step-by-step explanation:

Retail price of shirt = 40 dollar

Discount = 20%

Discount value:

=20% of 40 dollar                   [ 20/100 * 40 ⇒ 1/5 * 40 ⇒ 40/5 = 8 ]

= 8 dollar  [ discount value]

Price of shirt after discount :

= 40 - 8

= 32 dollar

As she paid 5% discount on the discounted price ( 32 dollar )

So,  5% of 32 = 1.6 dollar        [ 5/ 100 * 32 ⇒  1/20 * 32 ⇒ 32/20 = 1.6]

Amount to pay = 32( price after discount)  + 1.6 ( Tax)

= 33.60 dollar

Answer: you should expect 218,750 tons of pollutants from City B.

Step-by-step explanation:

When two variables vary "directly", it means that they fit into the equation y=mx, where y varies directly with x, with the multiplier m to be determined by the information you are given.

For this problem, P (pollutants) varies directly with N (people) so the equation is P=mN for their relation.

You are given that City A has P = 260,000 tons of pollutants and N = 416,000 people. Plug these into the equation above (P=mN) and you get 260,000=(m)(416,000). If we divide each side by 416,000, you get that m=0.625. So now you have the multiplier for your equation: P=(0.625)N.

Use the complete equation now to find out how many P (pollutants) City B will produce.

P=(0.625)N

P=(0.625)(350,000)      [[350,000 was the given "N" or amount of people in City B]]

P=218,750 tons of pollutants

The process of taking the observed values of x to estimate corresponding y values is called interpolation.

In interpolation, we use the known values of x to estimate or approximate the values of y that correspond to those x values. This is done by assuming that there is a functional relationship between x and y and using mathematical techniques to fill in the gaps between the observed data points.

Interpolation is commonly used in various fields such as statistics, mathematics, computer science, and engineering. It allows us to make predictions or obtain estimates for y values at specific x values within the range of the observed data.

There are different methods of interpolation, including linear interpolation, polynomial interpolation, and spline interpolation. These methods vary in complexity and accuracy depending on the nature of the data and the desired level of precision. The choice of interpolation method depends on the specific requirements of the problem at hand.

Three friends decide to share the cost to rent an apartment equally. The apartments that they are considering cost at least 1 200 per month. Write and solve an inequality to represent each person's share of the rental cost​

Lets highlight some key words.

There are three friends and they equally have to share an unknown amount of number to earn up to the 1200 per month,

X=Amount needed to pay the rent fee.

Since there are 3 friends and they have to split we have to multiply,

3x, "At least" is less than or equal to so .

3x \(\leq\)

Additionally theres 1200 per month so the friends need to share there rent and 1200 is the total it should be put as

3x \(\leq\) $1200

To add up to the rent, and to solve the inequality

we have to do the opposite of multiplication, and divide.

1200/3 = 400, x \(\leq\) 400

The domain and range need to be determined for a given relation, and it will be determined whether the relation represents a function.

To determine the domain and range of a relation, we need to examine the set of inputs (domain) and the set of corresponding outputs (range). The domain is the set of all possible input values for which the relation is defined, while the range is the set of all possible output values that result from the given inputs.

In the context of determining whether the relation represents a function, we need to ensure that each input value from the domain corresponds to a unique output value. If there is any input value that produces multiple output values, the relation is not a function.

To determine the domain, we examine the set of all valid input values. This can be based on restrictions or limitations stated in the problem or the nature of the relation itself. The range, on the other hand, is determined by observing the set of all output values that result from the given inputs.

Once the domain and range are determined, we can check if each input in the domain corresponds to a unique output in the range. If every input has a unique output, the relation represents a function. If there is any input that maps to multiple outputs, the relation does not represent a function.

Yes, the business did better on the second campaign. Since a higher ROI or ROAS value indicates better performance, the business did better on the second campaign.

ROI stands for Return on Investment, which is a measure of profitability. It is calculated by dividing the net profit by the total investment and expressing it as a percentage.

In this case, the ROI for the first campaign was 3, indicating that the business generated three times the profit compared to the investment.

ROAS stands for Return on Advertising Spend, which is a measure of the effectiveness of advertising campaigns. It is calculated by dividing the revenue generated by the advertising campaign by the cost of that campaign.

In this case, the ROAS for the second campaign was 4, indicating that the business generated four times the revenue compared to the advertising cost.

Since a higher ROI or ROAS value indicates better performance, the business did better on the second campaign. The ROAS value of 4 is higher than the ROI value of 3, indicating that the second campaign was more effective in terms of generating revenue compared to the investment made.
