Can you help with me with question 3.

1. About 3.079 is the valuef at which the equation holds true.

2. About 12.75 is the value of x that causes the equation to be true.

It often consists of variables, which are unknowable values that can change, and constants, whose values never change.

1. Using the two sides' combined logarithm:

[tex]log_{21}(21^{18})=log_{21}((21)^f^3)[/tex]

We can simplify the right-hand side using the logarithm property that

[tex]log\ a(b^c)=c\ log^x\ a(b)\\\\log_{21}(21^{18})=f^3\times log_{21}(21)[/tex]

Simplifying the right-hand side of the logarithm:

[tex]log_{21}(21)=1[/tex]

Adding this to the equation as a substitute:

[tex]log_{21}(21^{18})=f^3\times1[/tex]

Simplifying the left-hand side of the logarithm:

18 = f³

Using both sides' cube roots:

f = 18¹/³

Making the cube root simpler:

f = 2 × 3¹/³

2. First, we can separately simplify the fraction's numerator and denominator:

4¹⁷/⁴ ÷ 4¹¹/⁹ = (4¹⁷/⁴) × (4⁹/¹¹)

By removing the exponents of 4, we can now combine the two terms:

[tex]4^{(17/4-9/11)}=4^{(187/44)}[/tex]

The right side of the equation must then be simplified by taking the cube root of 4:

∛4 = 4¹/³

the equations are as follows:

[tex]4^{(187/44)}=4^{(1/3\times x)}[/tex]

We may compare the exponents of 4 using the property of exponents:

187/44 = 1/3 × x

Adding 3 to both sides:

x = 187/44 × 3

Multiplying and simplifying the fraction:

x = 187/44 × 3 = 561/44 ≈ 12.75

The answer of the given question based on the graph coordinate is , the rule for the values in the table is: Y = 7X - 0.

In mathematics, a coordinate is a set of values that specifies the position of a point in space. Coordinates are used to locate points, lines, and other geometric objects in a plane, a three-dimensional space, or even higher dimensions.

X    Y

5    35

1     7

4    28

2    14

One possible way to do this is to calculate the differences between successive pairs of X and Y values, and then see if there is a constant difference or ratio between them.

Taking the first two rows as an example, we have:

X Y

5 35

1 7

The difference between the X values is 5 - 1 = 4, and the difference between the Y values is 35 - 7 = 28. Dividing the difference in Y by the difference in X gives us:

(35 - 7) / (5 - 1) = 28 / 4 = 7

This means that for every increase of 1 in X, the corresponding increase in Y is 7. We can check this for the other pairs of values in the table and see that it holds true:

X Y

5 35

4 28 (decrease of 1 in X, decrease of 7 in Y)

2 14 (decrease of 2 in X, decrease of 14 in Y)

Let's call the amount of money Andy has "x".

According to the problem, Kelly has 7 pence more than Andy, so Kelly has x + 7 pence.

Georgia has a penny less than Andy, so Georgia has x - 1 pence.

The total amount of money they have is 1.48, which we can write as 148 pence.

So we can set up the equation:

x + (x + 7) + (x - 1) = 148

Simplifying and solving for x:

3x + 6 = 148

3x = 142

x = 47.33

Since we're dealing with pence, we'll round down to the nearest whole number:

x = 47

So Andy has 47 pence, Kelly has 54 pence (47 + 7), and Georgia has 46 pence (47 - 1).

The surface area of the pyramid is 64 square feet.

What is triangle?

A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.

To find the surface area of the pyramid, we need to find the area of each face and add them together.

First, let's find the area of the base, which is a square with side length 4 feet:

Area of base = 4 feet x 4 feet = 16 square feet

Next, we need to find the area of each triangular face. We know that the height of each triangular face is 6 feet, and the base of each triangular face is one of the sides of the square base, which is 4 feet. To find the area of a triangle, we use the formula:

Area of triangle = 1/2 x base x height

Area of each triangular face = 1/2 x 4 feet x 6 feet = 12 square feet

There are 4 triangular faces, so the total area of all the triangular faces is:

Total area of triangular faces = 4 x 12 square feet = 48 square feet

Now we can find the total surface area by adding the area of the base and the area of the triangular faces:

Total surface area = area of base + area of triangular faces

Total surface area = 16 square feet + 48 square feet

Total surface area = 64 square feet

Therefore, the surface area of the pyramid is 64 square feet.

The resort should sell a number of 255 packages at a price of $2400 per person to maximize their monthly profit and the maximal profit is $613,400.

Maximal profit refers to the highest level of profit that a business or organization can achieve given certain constraints such as cost, demand, or pricing. It is the point at which a company or business generates the most revenue after accounting for all expenses associated with production and distribution of goods or services. To determine the maximal profit, a business will need to find the optimal balance between costs and revenue, while also taking into account factors such as competition and market demand. This involves analyzing a variety of financial metrics such as revenue, cost of goods sold, gross profit margin, and net profit margin, among others.

Let's begin by defining some variables:

P = price of the package

Q = number of packages sold

R = revenue

C = cost

Profit = revenue - cost

Based on the information given, we can create the following equations:

R = P * Q

C = 1600 + 2000 * Q

Profit = R - C = P * Q - (1600 + 2000 * Q)

We want to find the price that will maximize the monthly profit. To do this, we need to find an expression for profit in terms of P only. We can use the equation for C to substitute Q in the expression for profit:

C = 1600 + 2000 * Q

Q = (C - 1600) / 2000

Profit = P * Q - (1600 + 2000 * Q)

Profit =

Profit = P * ((C - 1600) / 2000) - C + 1600

Now we can find the derivative of profit with respect to P:

dProfit/dP = (C - 1600) / 2000

To find the value of P that maximizes profit, we need to set the derivative equal to 0:

dProfit/dP = 0

(C - 1600) / 2000 = 0

C = 1600

This means that profit is maximized when revenue equals cost, which makes sense. Substituting C = 1600 into the expression for profit, we get:

Profit = P * ((1600 + 2000 * Q - 1600) / 2000) - 1600

Profit = P * Q - 1600

Now we need to find the corresponding values of P and Q. We know that for every increase of $100 in price, there will be a decrease of 5 in the number of packages sold. This means that:

Q = 300 - (P - 2000) / 100 * 5

Substituting this into the expression for profit, we get:

Profit = P * (300 - (P - 2000) / 100 * 5) - 1600

To find the maximum profit, we can take the derivative of this expression with respect to P and set it equal to 0:

dProfit/dP = 300 - (P - 2000) / 20 = 0

P = 2400

This means that the price that will maximize the monthly profit is $2400 per person. To find the corresponding number of packages sold, we can substitute this into the equation for Q:

Q = 300 - (2400 - 2000) / 100 * 5 = 255

Therefore, the resort should sell 255 packages at $2400 per person to maximize their monthly profit. To find the maximal profit, we can substitute these values into the expression for profit:

Profit = 2400 * 255 - 1600 = $613,400.

To find the LCM of 24 and 6, we can use the prime factorization method.

First, we find the prime factorization of each number:

24 = 2 x 2 x 2 x 3

6 = 2 x 3

Then, we identify the highest power of each prime factor that appears in either number.

The prime factor 2 appears three times in 24, but only once in 6. Therefore, we take the highest power of 2, which is 2 x 2 x 2 = 8.

The prime factor 3 appears once in both numbers, so we take the highest power of 3, which is 3.

Finally, we multiply these together to get the LCM:

LCM(24, 6) = 8 x 3 = 24

The scale factor of the dilation is 48.

The scale factor is a mathematical concept that describes the ratio of the lengths, areas, or volumes of two similar geometric figures. Similar figures have the same shape but may have different sizes.

When one figure is a dilation (a type of transformation that changes the size of a figure without changing its shape) of another figure, the scale factor is the ratio of the corresponding side lengths or dimensions of the two figures.

The scale factor of the dilation is the ratio of the length of the image to the length of the original object. In this case, the length of the image is 12 millimeters and the length of the original object is 0.25 millimeters. Therefore, the scale factor is:

scale factor = length of image/length of the original object

scale factor = 12 mm / 0.25 mm

scale factor = 48

Five points on the inverse function g(x) = log₄(x) are: (1, 0), (4, 1), (16, 2), (1/4, -1/2), and (2, 0.5).

Given that

f(x) = 4^x.

To find the inverse of the function f(x) = 4^x,

We need to interchange the positions of x and y and solve for y. So, we have:

x = 4^y

Taking the logarithm base 4 of both sides, we get:

y = log₄(x)

Therefore, the inverse of the function f(x) = 4^x is g(x) = log₄(x)

To find five points on the inverse function g(x), we can choose five x-values and find the corresponding y-values:

If x = 1, then g(x) = log₄(1) = 0, so the point is (1, 0).

If x = 4, then g(x) = log₄(4) = 1, so the point is (4, 1).

If x = 16, then g(x) = log₄(16) = 2, so the point is (16, 2).

If x = 1/4, then g(x) = log₄(1/4) = -1/2, so the point is (1/4, -1/2).

If x = 2, then g(x) = log₄(2) ≈ 0.5, so the point is (2, 0.5).

Therefore, five points on the inverse function g(x) = log₄(x) are: (1, 0), (4, 1), (16, 2), (1/4, -1/2), and (2, 0.5).
