The value of inverse function [tex]f^{(-1)}(5)[/tex] is 2 when function f(x)=√x+2+3.

To find [tex]f^{(-1)}(5)[/tex], we need to determine the value of x that satisfies f(x) = 5.

Given that f(x) = √(x+2) + 3, we can set √(x+2) + 3 equal to 5:

√(x+2) + 3 = 5

Subtracting 3 from both sides:

√(x+2) = 2

Now, let's square both sides to eliminate the square root:

a. The limit of lim x→27(x32−93x−3) is 2187

b The limit of lim x→2(x−2 4x+1−3) is 1/2

c. The limit of lim x→[infinity]4x2−3x+15x+3 is 0

d. The limit of lim x→0 tan(3x) cosec(2x) is 5/2

a. To find limx→27(x32−93x−3), first factor the numerator as (x - 27)(x³ + 3) and cancel out the common factor of x - 27 to get limx→27(x³ + 3)/(x - 27).

Since the numerator and denominator both go to 0 as x → 27, we can apply L'Hopital's rule and differentiate both the numerator and denominator with respect to x to get limx→27(3x²)/(1) = 3(27)² = 2187.

Therefore, the limit is 2187.

b. To find limx→2(x - 2)/(4x + 1 - 3), we can factor the denominator as 4(x - 2) + 1 and simplify to get limx→2(x - 2)/(4(x - 2) + 1 - 3) = limx→2(x - 2)/(4(x - 2) - 2). We can then cancel out the common factor of x - 2 to get limx→2(1)/(4 - 2) = 1/2

. Therefore, the limit is 1/2.

c. To find limx→∞4x² - 3x + 15/x + 3, we can apply the concept of limits at infinity, where we divide both the numerator and denominator by the highest power of x in the expression, which in this case is x², to get limx→∞(4 - 3/x + 15/x²)/(1/x + 3/x²).

As x → ∞, both the numerator and denominator go to 0, so we can apply L'Hopital's rule and differentiate both the numerator and denominator with respect to x to get limx→∞(6/x³)/(1/x² + 6/x³) = limx→∞6/(x + 6) = 0.

Therefore, the limit is 0.

d. To find limx→0 tan(3x)cosec(2x), we can substitute sin(2x)/cos(2x) for cosec(2x) to get limx→0 tan(3x)cosec(2x) = limx→0 (tan(3x)sin(2x))/cos(2x).

We can then substitute sin(3x)/cos(3x) for tan(3x) and simplify to get limx→0 (sin(3x)sin(2x))/cos(2x)cos(3x).

We can then use the trigonometric identity sin(a + b) = sin(a)cos(b) + cos(a)sin(b) to simplify the numerator to sin(5x)/2, and the denominator simplifies to cos²(3x) - sin²(3x)cos(2x).

We can then use the trigonometric identity cos(2a) = 1 - 2sin²(a) to simplify the denominator to 2cos³(3x) - 3cos(3x), and we can substitute 0 for cos(3x) and simplify to get limx→0 sin(5x)/[2(1 - 3cos²(3x))] = limx→0 5cos(3x)/[2(1 - 3cos²(3x))] = 5/2.

Therefore, the limit is 5/2.

The height of the triangular pyramid is 9 centimeters.

To calculate the height of the triangular pyramid, we can use the formula for the volume of a pyramid: Volume = (1/3) * Base Area * Height. In this case, the base of the pyramid is a right triangle with a leg of 8 centimeters and a hypotenuse of 10 centimeters.

The formula for the area of a right triangle is: Base Area = (1/2) * Base * Height. Since we are given the length of one leg (8 centimeters), we can use the Pythagorean theorem to find the length of the other leg. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Let's denote the height of the right triangle as 'h'. Using the Pythagorean theorem, we have: (8^2) + (h^2) = (10^2). Simplifying this equation, we get: 64 + h^2 = 100. Rearranging the equation, we have: h^2 = 100 - 64 = 36. Taking the square root of both sides, we find that the height of the right triangle is h = 6 centimeters.

Now that we have the base area and the height of the triangular pyramid, we can use the volume formula to find the height of the pyramid. The given volume is 144 cubic centimeters, so we have the equation: 144 = (1/3) * Base Area * Height. Plugging in the values, we get: 144 = (1/3) * (1/2) * 8 * 6 * Height. Simplifying this equation, we have: 144 = 4 * Height. Dividing both sides by 4, we find: Height = 36/4 = 9 centimeters.

Therefore, the height of the triangular pyramid is 9 centimeters.

The flux from top to bottom (through the bottom) of the cone shell B := (x, y, z) = R³ : x² + y² ≤ 1, z = 1 is u.

Given vectorfield: v(x, y, z) = (yz, −xz, x² + y²)

Conical frustum K := (x, y, z) = R³ : x² + y² < z², 1 < ≈ < 2

We need to calculate the flux from top to bottom (through the bottom) of the cone shell B :

= (x, y, z) = R³ : x² + y² ≤ 1, z = 1.

A cone shell can be expressed as given below;`x^2 + y^2 = r^2 , 1 <= z <= 2, 0 <= r <= z.

`Given that the vector field is;`v(x, y, z) = (yz, −xz, x² + y²)`We can calculate flux through surface integral as follows;

∫∫F.ds = ∫∫F.n dS , where n is the outward normal to the surface and dS is the surface element.

We need to calculate the flux through the closed surface. The conical frustum is open surface, so we will need to use Divergence theorem to find the flux from the top to bottom through the bottom of the cone shell.

In Divergence theorem, the flux through a closed surface is equal to the triple integral of the divergence of the vector field over the volume enclosed by the surface i.e.

,[tex]\iiint_D\nabla . F dV = \iint_S F. NdS[/tex].

In this problem, Divergence theorem can be given as;[tex]\iint_S F. NdS = \iiint_D\nabla . F dV[/tex]

We can write the vector field divergence [tex]\nabla . F as;\nabla . F = \frac{{\partial }}{{\partial x}}\left( {yz} \right) - \frac{{\partial }}{{\partial y}}\left( {xz} \right) + \frac{{\partial }}{{\partial z}}\left( {{x^2} + {y^2}} \right)\nabla[/tex]. F = y - x.

We can integrate this over the given cone shell region to get the flux through the surface. But as the cone shell is an open surface, we will need to use the Divergence theorem.

Now, we will calculate the flux from the top to bottom (through the bottom) of the cone shell.[tex]= \iiint_D {\nabla . F dV} = \int\limits_1^2 {\int\limits_0^{2\pi } {\int\limits_1^z {\left( {y - x} \right)dzd\theta dr} } }This can be calculated as; = \int\limits_1^2 {\int\limits_0^{2\pi } {\left( {\frac{1}{2}{z^2} - \frac{1}{2}} \right)d\theta dz} }[/tex]

This gives us the flux as;

[tex]= \int\limits_1^2 {\int\limits_0^{2\pi } {\left( {\frac{1}{2}{z^2} - \frac{1}{2}} \right)d\theta dz} } = \pi\left[ {\frac{7}{3} - \frac{1}{3}} \right] = \frac{{6\pi }}{3} = 2\pi[/tex]

To find the eigenvalues, we solve the characteristic equation det(A - λI) = 0, where A is the given matrix and I is the identity matrix. This equation gives us the polynomial λ³ - λ² - λ + 4 = 0.

By solving the polynomial equation, we find the eigenvalues λ₁ = -1, λ₂ = 1, and λ₃ = 4.

For each eigenvalue, we subtract λ times the identity matrix from matrix A and row reduce the resulting matrix to obtain a row-reduced echelon form.

From the row-reduced form, we can identify the variables that are free (resulting in a row of zeros) and choose appropriate values for those variables.

By solving the resulting system of equations, we find the corresponding eigenvectors.

The substance with a lower hydrogen ion concentration has a greater pH level, and the substance with a higher hydrogen ion concentration has a lower pH level. The pH level of Substance A minus the pH level of Substance B equals 0.3 (8.7 - 9)

The substance with lower hydrogen ion concentration has a greater pH level. If the hydrogen ion concentration of substance A is twice that of substance B, then substance B has a higher pH level. What is the greater pH level minus the lesser pH level?

The pH scale is logarithmic, ranging from 0 to 14. If Substance B has a hydrogen ion concentration of 1 x 10^-9 moles per liter (pH 9), Substance A would have a hydrogen ion concentration of 2 x 10^-9 moles per liter (pH 8.7). Therefore, the pH level of Substance A minus the pH level of Substance B equals 0.3 (8.7 - 9).

Explanation: The hydrogen ion concentration and the pH level are inversely related. pH is defined as the negative logarithm of the hydrogen ion concentration. The lower the hydrogen ion concentration, the higher the pH level, and vice versa. As a result, the substance with a lower hydrogen ion concentration has a greater pH level, and the substance with a higher hydrogen ion concentration has a lower pH level.

ϕ (m/n) = ϕ (m)/ϕ (n) if and only if m = nk, where (n,k) = 1.

First, we need to understand the concept of Euler's totient function (ϕ). The totient function ϕ(n) calculates the number of positive integers less than or equal to n that are coprime (relatively prime) to n. In other words, it counts the number of positive integers less than or equal to n that do not share any common factors with n.

To prove the given statement, we start with the assumption that ϕ(m/n) = ϕ(m)/ϕ(n). This implies that the number of positive integers less than or equal to m/n that are coprime to m/n is equal to the ratio of the number of positive integers less than or equal to m that are coprime to m, divided by the number of positive integers less than or equal to n that are coprime to n.

Now, let's consider the case where m = nk, where (n,k) = 1. This means that m is divisible by n, and n and k do not have any common factors other than 1. In this case, every positive integer less than or equal to m will also be less than or equal to m/n. Moreover, any positive integer that is coprime to m will also be coprime to m/n since dividing by n does not introduce any new common factors.

Therefore, in this case, the number of positive integers less than or equal to m that are coprime to m is the same as the number of positive integers less than or equal to m/n that are coprime to m/n. This leads to ϕ(m) = ϕ(m/n), and since ϕ(m/n) = ϕ(m)/ϕ(n) (from the assumption), we can conclude that ϕ(m) = ϕ(m)/ϕ(n). This proves the given statement.

x^2+13x-2x-26

x(x+13) -2(x+13)

(x+13) (x-2)

Answer:

Step-by-step explanation

A) To factorize x^2 + 11x - 26, we need to find two numbers that multiply to give -26 and add to give 11. These numbers are 13 and -2. Therefore, we can write:

x^2 + 11x - 26 = (x + 13)(x - 2)

B) To factorize x^2 -5x -24, we need to find two numbers that multiply to give -24 and add to give -5. These numbers are -8 and 3. Therefore, we can write:

x^2 -5x -24 = (x - 8)(x + 3)

C) To factorize 9x^2 + 6x - 8, we first need to factor out the common factor of 3:

9x^2 + 6x - 8 = 3(3x^2 + 2x - 8)

Now we need to find two numbers that multiply to give -24 and add to give 2. These numbers are 6 and -4. Therefore, we can write:

9x^2 + 6x - 8 = 3(3x + 4)(x - 2)

The single discount rate that is equivalent to the given trade discounts is 24.5%. The last date to get the 4% cash discount is 24 June 2020. The amount of trade discount received is RM 1,305. The amount paid if payment was made on 20 June 2020 is RM 8,395.20.

To calculate the single discount rate equivalent to the given trade discounts, we can use the formula:

Single Discount Rate = 1 - [(1 - Trade Discount Rate 1) × (1 - Trade Discount Rate 2)]

Substituting the given trade discount rates, we get:

Single Discount Rate = 1 - [(1 - 10%) × (1 - 15%)]

                   = 1 - [(0.9) × (0.85)]

                   = 1 - 0.765

                   = 0.235

                   = 23.5%

However, the given trade discount rates are calculated based on the list prices before including the transportation cost. So, we need to adjust the trade discount rate by considering the transportation cost. Dividing the transportation cost (RM 400) by the total list price before discount (RM 4,160), we get 0.0962, which is approximately 9.62%. Adding this adjusted transportation cost percentage to the single discount rate calculated above, we get:

Single Discount Rate = 23.5% + 9.62%

                   = 33.12%

                  ≈ 33.1%

To find the last date to get the 4% cash discount, we use the cash discount terms. The "n" in the terms represents the number of days after the discount period ends, which is 30 days. Subtracting "n" from the given invoice date of 14 June 2020, we get the last date for the cash discount:

Last Date = Invoice Date + Discount Period - n

         = 14 June 2020 + 10 days - 30 days

         = 24 June 2020

The amount of trade discount received can be calculated by multiplying the list price per unit by the quantity and then applying the single discount rate:

Amount of Trade Discount = (Tyre Price × Tyre Quantity + Battery Price × Battery Quantity + Sport Rim Price × Sport Rim Quantity) × Single Discount Rate

                      = (110 × 8 + 160 × 12 + 180 × 15) × 33.1%

                      = RM 1,305

Finally, to calculate the amount paid if payment was made on 20 June 2020, we subtract the cash discount (4%) from the invoice amount and apply the single discount rate:

Amount Paid = (Invoice Amount - Cash Discount) × (1 - Single Discount Rate)

          = (Total List Price + Transportation Cost - Trade Discount) × (1 - Single Discount Rate)

           = (RM 4,160 + RM 400 - RM 1,305) × (1 - 33.1%)

           = RM 2,255 × 66.9%

           = RM 8,395.20

Where a, b, and c are coefficients in the quadratic equation, ax² + bx + c. In our equation, a = − 16, b = 89, and c = 50. Therefore:x = [ - 89 ± sqrt( 89² - 4 (- 16) (50))] / ( 2 (- 16))x = [ - 89 ± sqrt( 5041 + 3200)] / - 32x = [ - 89 ± sqrt( 8241)] / - 32x = [ - 89 ± 91] / - 32.

There are two solutions for x. One solution is: x = ( - 89 + 91 ) / - 32 = - 0.0625.

The other solution is:x = ( - 89 - 91 ) / - 32 = 5.5625.The time that the rocket will hit the ground is 5.5625 seconds (to the nearest 100th of a second). Therefore, the answer is:5.56 seconds (rounded to the nearest 100th of a second).

The time that the rocket would hit the ground is 2.95 seconds.

Based on the information provided, we can logically deduce that the height (h) in feet, of this rocket above the​ ground is related to time by the following quadratic function:

h(t) = -16x² + 89x + 50

Generally speaking, the height of this rocket would be equal to zero (0) when it hits the ground. Therefore, we would equate the height function to zero (0) as follows:

0 = -16x² + 89x + 50

16t² - 89 - 50 = 0

[tex]t = \frac{-(-80)\; \pm \;\sqrt{(-80)^2 - 4(16)(-50)}}{2(16)}[/tex]

Time, t = (√139)/4

Time, t = 2.95 seconds.

We would expect to capture 50% of the market share with the new competing store at location (x = 3, y = 2) with twice the capacity of the existing copy center.

To determine the market share we would expect to capture with the new competing store, we can use the gravity model of market share. The gravity model is commonly used to estimate the flow or interaction between two locations based on their distances and attractiveness.

In this case, the attractiveness of each location can be represented by the capacity of the copy center. Let's denote the capacity of the existing copy center as C1 = 1 (since it has the capacity of 1) and the capacity of the new competing store as C2 = 2 (twice the capacity).

The market share (MS) can be calculated using the following formula:

MS = (C1 * C2) / ((A * d^2) + (C1 * C2))

Where:

- A represents the attractiveness factor (convenience) = 2

- d represents the distance between the two locations (x = 2 to x = 3 in this case) = 1

Plugging in the values:

MS = (1 * 2) / ((2 * 1^2) + (1 * 2))

  = 2 / (2 + 2)

  = 2 / 4

The new competing store would capture approximately 2/3 (or 66.67%) of the market share.

To determine the market share that the new competing store at (x = 3, y = 2) would capture, we need to compare its attractiveness with the existing copy center located at (x = 2, y = 2).

b

Let's calculate the attractiveness of the existing copy center first:

Attractiveness of the existing copy center:

A = 2

Expenditure per customer order: $10

Next, let's calculate the attractiveness of the new competing store:

Attractiveness of the new competing store:

A' = 2 (same as the existing copy center)

Expenditure per customer order: $10 (same as the existing copy center)

Capacity of the new competing store: Twice the capacity of the existing copy center

Since the capacity of the new competing store is twice that of the existing copy center, we can consider that the new store can potentially capture twice as many customers.

Now, to calculate the market share captured by the new competing store, we need to compare the capacity of the existing copy center with the total capacity (existing + new store):

Market share captured by the new competing store = (Capacity of the new competing store) / (Total capacity)

Let's denote the capacity of the existing copy center as C and the capacity of the new competing store as C'.

Since the capacity of the new store is twice that of the existing copy center, we have:

C' = 2C

Total capacity = C + C'

Now, substituting the values:

C' = 2C

Total capacity = C + 2C = 3C

Market share captured by the new competing store = (C') / (Total capacity) = (2C) / (3C) = 2/3

Based on the given CDI and BDI values, investing in Segment 2 would be more advantageous for the brand.

Brand X's growth can be determined by analysing  CDI (Category Development Index) and BDI (Brand Development Index) in two segments, Segment 1 and Segment 2.

Segment 1 has a CDI of 125 and a BDI of 95, while Segment 2 has a CDI of 85 and a BDI of 110. Based on the CDI and BDI values, Segment 2 appears to be a more favourable investment opportunity for the brand because the BDI is higher than the CDI.

CDI is an index that compares the percentage of a company's sales in a specific market area to the percentage of the country's population in the same market area. It provides insights into the market penetration of the brand in relation to the overall population.

BDI, on the other hand, compares the percentage of a company's sales in a given market area to the percentage of the product category's sales in that same market area. It indicates the brand's performance relative to the product category within a specific market.

A higher BDI suggests that the product category is performing well in the market area, indicating a higher growth potential for the brand. Conversely, a higher CDI indicates that the brand already has a strong presence in the market area, implying limited room for further growth.

Therefore, The higher BDI suggests a stronger potential for growth in this market compared to Segment 1, where the CDI is higher than the BDI. By focusing on Segment 2, the brand can tap into the market's growth potential and expand its market share effectively.

Step-by-step explanation:

14. There are 56 different arrangements of president and vice-president possible in a club consisting of eight members.

16. There are 10 different arrangements possible.

14. Finding the number of different arrangements of president and vice-president in a club with eight members, consider that the positions of president and vice-president are distinct.

For the position of the president, there are eight members who can be chosen. Once the president is chosen, there are seven remaining members who can be selected as the vice-president.

The total number of different arrangements is obtained by multiplying the number of choices for the president (8) by the number of choices for the vice-president (7). This gives us:

8 * 7 = 56

16. To determine the number of different arrangements possible for Tito's essay, we can use the concept of combinations. Tito has to choose three questions out of the five available to write his essay. The number of different arrangements can be calculated using the formula for combinations, which is represented as "nCr" or "C(n,r)." In this case, we have 5 questions (n) and Tito needs to choose 3 questions (r) to write his essay.

Using the combination formula, the number of different arrangements can be calculated as:

[tex]C(5,3) = 5! / (3! * (5-3)!)= (5 * 4 * 3!) / (3! * 2 * 1)= (5 * 4) / (2 * 1)= 20 / 2= 10[/tex]

Step-by-step explanation:

Round the number based on the sixth digit. That is the millionth.

The solution to the given system of linear equations is x₁ = 20/7 and x₂ = 40/7. This solution is obtained by using the inverse matrix method.

To solve the system of linear equations using an inverse matrix, we'll start by representing the system in matrix form. Let's consider the given system of equations:

Equation 1: 5x₁ + 4x₂ = 40

We can rewrite this equation as:

[ 5  4 ] [ x₁ ] = [ 40 ]

Now, let's find the inverse of the coefficient matrix [ 5  4 ]:

[ 5  4 ]⁻¹ = [ a  b ]

                [ c  d ]

To calculate the inverse, we'll use the following formula:

[ a  b ]   [  d -b ]

[ c  d ] = [ -c  a ]

Let's substitute the values from the coefficient matrix to calculate the inverse:

[ 5  4 ]⁻¹ = [  4/7  -4/7 ]

                [ -5/7   5/7 ]

Now, we can solve for the variable matrix [ x₁ ] using the inverse matrix:

[  4/7  -4/7 ] [ x₁ ] = [ 40 ]

[ -5/7   5/7 ]

By multiplying the inverse matrix with the constant matrix, we can find the values of x₁ and x₂. Let's perform the matrix multiplication:

[ x₁ ] = [  4/7  -4/7 ] [ 40 ] = [ 20/7 ]

                                          [ 40/7 ]

Therefore, the solution to the system of linear equations is:

x₁ = 20/7

x₂ = 40/7

The equation in a standard form that has the solutions x = 2 ± √2.

To find an equation with the given solutions x = 2 ± √2, we can use the fact that the solutions of a quadratic equation are given by the formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

In this case, we have x = 2 ± √2, which means our equation will have solutions that satisfy:

x - 2 ± √2 = 0

To eliminate the square root, we can square both sides:

(x - 2 ± √2)^2 = 0

Expanding the equation:

(x - 2)^2 ± 2(x - 2)√2 + (√2)^2 = 0

Simplifying:

(x^2 - 4x + 4) ± 2√2(x - 2) + 2 = 0

Rearranging terms and combining like terms:

x^2 - 4x + 4 ± 2√2(x - 2) + 2 = 0

x^2 - 4x + 6 ± 2√2(x - 2) = 0

The function f(x) is undefined when x = -8 or x = 1. The domain of f(x) is all real numbers except -8 and 1. In interval notation, the domain can be expressed as (-∞, -8) U (-8, 1) U (1, ∞).

To find the domain of the function f(x) = 3/(x+8) + 5/(x-1), we need to identify any values of x that would make the function undefined.

The function f(x) is undefined when the denominator of any fraction becomes zero, as division by zero is not defined.

In this case, the denominators are x+8 and x-1. To find the values of x that make these denominators zero, we set them equal to zero and solve for x:

x+8 = 0 (Denominator 1)

x = -8

x-1 = 0 (Denominator 2)

x = 1

Therefore, the function f(x) is undefined when x = -8 or x = 1.

The equation 3/2x - 5/3x = 2 can be solved as follows:

x = 12

To solve the equation 3/2x - 5/3x = 2, we need to isolate the variable x.

First, we'll simplify the equation by finding a common denominator for the fractions. The common denominator for 2 and 3 is 6. Thus, we have:

(9/6)x - (10/6)x = 2

Next, we'll combine the like terms on the left side of the equation:

(-1/6)x = 2

To isolate x, we'll multiply both sides of the equation by the reciprocal of (-1/6), which is -6/1:

x = (2)(-6/1)

Simplifying, we get:

x = -12/1

x = -12

To check the solution, we substitute x = -12 back into the original equation:

3/2(-12) - 5/3(-12) = 2

-18 - 20 = 2

-38 = 2

Since -38 is not equal to 2, the solution x = -12 does not satisfy the equation.

Therefore, there is no solution to the equation 3/2x - 5/3x = 2.
