the given pairs of functions are inverse of each other.

A function that can reverse into another function is known as an inverse function or anti-function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as "f-1" or "F-1." Here, (-1) should not be confused with an exponent or a reciprocal.

We have two function

f(x) = √(x+4)+9

let y=√(x+4)+9

y-9=√(x+4)

(y-9)²=x+4

x=(y-9)²-4

inverse of f(x) is (x-9)²-4

Now for g(x)= (x-9)²-4

The inverse of g(x)

In the given equation the value of mº is 17°. Answer: (D) 49 = 32° + mº.

A triangle is a geometrical figure with three straight sides and three angles. It is the simplest polygon and the building block for more complex shapes.

There are several kinds of triangles:

Equilateral triangle: This is a triangle with three equal sides and three equal angles of 60 degrees each.

Isosceles triangle: This is a triangle with two equal sides and two equal angles.

Scalene triangle: This is a triangle with no equal sides or angles.

Right-angled triangle: This is a triangle with one angle of 90 degrees, which is also known as the right angle. The side opposite to the right angle is the longest side, called the hypotenuse, while the other two sides are called legs.

Acute triangle: This is a triangle in which all three angles are acute angles, meaning they are less than 90 degrees.

Obtuse triangle: This is a triangle in which one angle is an obtuse angle, meaning it is greater than 90 degrees. The other two angles are acute angles.

The equation that can be used to solve for mº depends on the given information or conditions. If the problem provides the measures of two angles and their sum, then we can use the equation:

A + B + m = 180°

where A and B are the measures of the given angles, and m is the measure of the unknown angle in degrees.

However, if the problem only gives the measures of two angles and their sum is not required, we can use the equation:

A + B = m

where A and B are the measures of the given angles, and m is the measure of the unknown angle in degrees.

Based on the given information in the question, we are only provided with the measures of two angles, 49° and 32°, and there is no indication that their sum is required. Therefore, the correct equation to solve for mº is:

49° = 32° + mº

We can simplify this equation to solve for mº:

49° - 32° = mº

mº = 17°

Therefore, the value of mº is 17°. Answer: (D) 49 = 32° + mº.

Answer:

Step-by-step explanation:

Answer:Let's assume that the cost price for both products A and B is "C", and the selling price for both products A and B is "S". We can use this information to set up two equations, one for Tom and one for John, that relate the costs and profits for the two products:

Tom: 5C - 2(5S) = P1

John: 3(5C) - 13C = P2

where P1 and P2 are the profits made by Tom and John, respectively.

We know that at the end of the business day, John banks Ksh 110,000/- while Tom banks Ksh

230,000. So we can write:

P1 = 230,000 - 5C

P2 = 110,000 - 18C

Substituting these values into the equations for Tom and John, we get:

5C - 2(5S) = 230.000 - 5C

Simplifying these equations, we get:

10C - 10S = 230,000

2C = 110,000

Solving for C, we get:

C = 55,000

Substituting this value back into the first equation, we can solve for S:

10(55,000) - 10S = 230,000

Simplifying this equation, we get:

S = 32,000

Therefore, the price for product A is Ksh 55,000 and the price for product B is Ksh 32,000.

Approximately 75 students voted for the eagle.

A fraction is a numerical quantity that represents a part of a whole or a quotient of two numbers. It consists of two numbers separated by a horizontal or diagonal line called a fraction bar or a division bar.

The falcon won with 5/8 of the votes, which means that 3/8 of the votes were for the other candidates (since 5/8 + 3/8 = 1).

Let's represent the total number of votes as "x".

Then, the number of votes for the falcon is (5/8)x and the number of votes for the other candidates is (3/8)x.

Out of these other candidates, the eagle received 1/3 of the votes. So, the number of votes for the eagle is:

(1/3)(3/8)x = (1/8)x

We know that the total number of votes is 536, so we can set up the equation:

(5/8)x + (3/8)x + (1/8)x = 536

Simplifying the equation, we get:

(9/8)x = 536

Multiplying both sides by 8/9, we get:

x = 596

Therefore, the number of votes for the eagle is:

(1/8)x = (1/8)(596) = 74.5

Therefore, approximately 75 students voted for the eagle.

And so on.

A Maclaurin series, named after the Scottish mathematician Colin Maclaurin, is a special type of power series expansion of a function that is centered at zero. In other words, it is a way to represent a function as an infinite sum of terms that involve the function's derivatives evaluated at zero.

The general form of a Maclaurin series for a function f(x) is given by:

[tex]f(x) = f(0) + f'(0)x + (f''(0)/2!)x^2 + (f'''(0)/3!)x^3 + ...[/tex]

To evaluate the function f(x) = x^2 * [tex]e^x[/tex] using Maclaurin series, we can first find the Maclaurin series for [tex]e^x[/tex] and then multiply it with x^2 to obtain the Maclaurin series for f(x).

The Maclaurin series for [tex]e^x[/tex]is given by:

[tex]e^x = 1 + x + x^2/2! + x^3/3! + x^4/4! + ...[/tex]

Multiplying both sides by x^2, we get:

[tex]x^2 * e^x = x^2 + x^3 + x^4/2! + x^5/3! + x^6/4! + ...[/tex]

Therefore, the Maclaurin series for f(x) is:

[tex]f(x) = x^2 * e^x = x^2 + x^3 + x^4/2! + x^5/3! + x^6/4! + ...[/tex]

To approximate the value of f(x) using the Maclaurin series, we can truncate the series after a certain number of terms. The more terms we include, the more accurate the approximation will be. For example, if we use the first three terms of the series, we get:

Answer:

The given expression is,

-1/6+2/3(9-3/4)-1/2

According to BODMAS rule, we first do the operation of bracket ( as B comes first in the BODMAS).

∴ 9-3/4= (36-3)/4=33/4

Putting 33/4 in place of (9-3/4), the expression becomes

-1/6+2/3×33/4-1/2

Now, the priority of M in BODMAS is more than A and S, so we do the operation of multiplication.

∴2/3×33/4=11/2 ( as 33÷3=11 and 4÷2=2)

Replacing 2/3×33/4 by 11/2, the expression becomes,

-1/6+11/2-1/2

= -1/6+(11-1)/2

= -1/6+5

The combination of goods that would maximize the consumer's Utility per dollar leads to a utility equal to 14 utils.

To determine the combination of goods that would maximize the consumer's utility per dollar, we need to use the concept of marginal utility. Assuming that the consumer has $14 to spend and chips cost $1 while soda costs $2, the consumer could purchase either 14 chips, 7 sodas or a combination of the two.

Let's say the consumer decides to buy x chips and y sodas. The total expenditure would be 1x + 2y, and the total utility would be the sum of the marginal utility of each good multiplied by the quantity purchased.

Assuming the utility function is U(x, y) = x^(1/2) * y^(1/2), the marginal utility of chips would be (1/2)x^(-1/2)*y^(1/2) and the marginal utility of soda would be (1/2)x^(1/2)*y^(-1/2).

The consumer's goal is to maximize the utility per dollar, which is calculated as the total utility divided by the total expenditure. Therefore, the utility per dollar function would be U(x, y)/(1x + 2y).

Using the Lagrange multiplier method, we can find the combination of x and y that maximizes the utility per dollar. The first-order conditions give us the following system of equations:

(1/2)x^(-1/2)*y^(1/2) = λ

(1/2)x^(1/2)*y^(-1/2) = 2λ

x^(1/2)*y^(1/2) = 14

Solving this system of equations, we get x = 4 and y = 49/4. Therefore, the consumer should buy 4 chips and 12.25 sodas, which costs $29.50.

The utility function evaluated at this point is U(4, 49/4) = (4^(1/2))*(49/4)^(1/2) = 14. The utility per dollar function evaluated at this point is U(4, 49/4)/(1(4) + 2(49/4)) = 14/29.50 = 0.4746.

Therefore, the combination of goods that would maximize the consumer's utility per dollar leads to a utility equal to 14 utils.

To solve this expression, we need to apply the order of operations (also known as PEMDAS): 8 15/22 - 3/4 x 2 divided by 12 = 351/44.

What is PEMDAS?

1.  First, we need to simplify any expressions inside parentheses, but there are no parentheses in this expression.

2. Next, we need to perform any multiplication or division, working from left to right. So, we need to calculate 3/4 x 2 = 3/2.

3. Then, we can rewrite the expression with the new result: 8 15/22 - 3/2 divided by 12.

4. Next, we need to perform the division, which means we need to divide 3/2 by 12. To do this, we can rewrite 12 as a fraction with a denominator of 2: 12/1 x 1/2 = 6/1. Then, we can simplify 3/2 divided by 6/1 by multiplying by the reciprocal of 6/1: (3/2) x (1/6) = 1/4.

5. Now we can substitute this value back into the expression: 8 15/22 - 1/4.

6. Finally, we need to convert the mixed number 8 15/22 to an improper fraction: 8 x 22/22 + 15/22 = 181/22.

7. Now we can combine like terms: 181/22 - 1/4 = (181 x 4)/(22 x 4) - 1/4 = 724/88 - 22/88 = 702/88.

8. We can simplify the fraction by dividing both the numerator and denominator by the greatest common factor (GCF), which is 2: 702/88 = 351/44.

Therefore, 8 15/22 - 3/4 x 2 divided by 12 is equal to 351/44.

The surface area of an object indicates the overall space occupied by its surface. The surface area of a three-dimensional form is the entire amount of space that surrounds it. The surface area of a three-dimensional form refers to its full surface area. By summing the areas of each face, the surface area of a cuboid with six rectangular faces may be computed. As an alternative, you may use the following formula to name the box's dimensions: 2lh + 2lw + 2hw = surface (SA). Surface area is a measurement of the total amount of space occupied by the surface of a three-dimensional form (a three-dimensional shape is a shape that has height, width, and depth).

To get the surface area of the prism, sum the areas of all six faces.

The top and bottom rectangular faces have the same size and area:

10 feet x 8 feet = 80 square feet

The dimensions of the other four faces are the same:

12 feet tall x 10 feet wide = 120 square feet

As a result, the total surface area is:

[tex]31.5*HE =21^{2}[/tex]

[tex]HE = 21^{2} /31.5 = 14[/tex]

Now, we can use the same property to find [tex]HC[/tex]. That is,

[tex]HC *HE =HG^{2}[/tex]

Substituting the values we have found, we get:

[tex]HC*14 = 21^{2} \\HC = 21^{2} /14 = 31.5[/tex]

Therefore, the length of the secant segment [tex]HC = 31.5[/tex].

b) [tex]VX*VZ= VY*VW[/tex]

Substituting the given values, we get:

[tex]14.4*12= VY *36\\VY = (14.4*12)/36 = 4.8[/tex]

Therefore, the length of [tex]VY, XY = 4.8[/tex]

Answer:

Step-by-step explanation:

The prism A have lateral surface area = 685 and total surface area = 1021, while the prism B have lateral surface area = 328 and total surface area = 448.

The triangular prisms A and B have two same size triangle faces and two different size rectangle face with a rectangle bottom face.

For 6 and 7;

area of one triangle face = 1/2 × 21 × 9

area of one triangle face = 94.5

area of the two triangle faces = 2(94.5) = 189

area of one smaller rectangle face = 16 × 14 = 224

area of one bigger rectangle face = 17 × 16 = 272

Area of lateral surface area = 188 + 224 + 272 = 685

Area of bottom rectangle face = 21 × 16 = 336

Total surface area of prism A = 685 + 336 = 1021

For 8 and 9;

area of one triangle face = 1/2 × 24 ×

area of one triangle face = 84

area of the two triangle faces = 2(84) = 168

area of one smaller rectangle face = 7 × 5 = 35

area of one bigger rectangle face = 25 × 5 = 125

Area of lateral surface area = 168 + 35 + 125 = 328

Area of bottom rectangle face = 24 × 5 = 120

Total surface area of prism A = 328 + 120 = 448

Therefore, the prism A have lateral surface area = 685 and total surface area = 1021, while the prism B have lateral surface area = 328 and total surface area = 448.
