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).

The solution of the system of equations given y = -6x + 5 and 4x - y = 5,  is (1, -1).

To solve this system of equations, we can use the substitution method. We can rearrange the first equation to solve for y in terms of x:

y = -6x + 5

Next, we can substitute this expression for y in the second equation:

4x - (-6x + 5) = 5

Simplifying this equation, we get:

4x + 6x - 5 = 5

Combining like terms, we get:

10x = 10

Dividing both sides by 10, we get:

x = 1

Now that we have the value of x, we can substitute it back into one of the original equations to solve for y. Using the first equation, we get:

y = -6(1) + 5 = -1

Therefore, the solution of the system of equations is (1, -1). This means that the two equations intersect at the point (1, -1) on the coordinate plane, and this is the only point that satisfies both equations simultaneously.

In summary, to solve the system of equations y = -6x + 5 and 4x - y = 5, we used the substitution method to find that the solution is (1, -1).

The cash payback period for the project is 4.7 years.

The cash payback period is a financial metric that calculates the amount of time it takes for a project to generate enough cash flows to recover the initial investment (cost). It is calculated by dividing the initial investment by the estimated annual net cash flows.

Decimal refers to a system of numbers based on the number 10, where each digit represents a different power of 10. It is a way of expressing numbers using a decimal point to separate the whole number from the fractional part.

Given:

Estimated annual net cash flows = $55,800

Initial investment (cost) = $262,260

Cash Payback Period = Initial Investment / Estimated Annual Net Cash Flows

Putting the values:

Cash Payback Period = $262,260 / $55,800

Calculating the cash payback period:

Cash Payback Period = 4.7 years (rounded to one decimal place)

The perimeter of a square is the sum of its sides and they are all equal, so to obtain the length of each of them we divide the perimeter of the first fence between 4:

[tex]\text{P1}= \dfrac{\text{64 feet}}{\text{4 sides}}[/tex]

[tex]\text{P1}= 16 \ \text{feet}[/tex]

Then, the length of each side of the second fence will increase 2 feet at each end, as shown in the figure. We have then that the perimeter of the second fence is:

[tex]\text{P2 = 20 feet} \times \text{4 sides}[/tex]

[tex]\text{P2 = 80 feet}[/tex]

The sum of the perimeters of both fences is:

[tex]\text{PT = P1 + P2}[/tex]

[tex]\text{PT = 64 feet + 80 feet}[/tex]

[tex]\text{PT = 144 feet}[/tex]

A- Tanya's gross income for the first year was $7,940, and b- her net income was $5,840 after subtracting her total expenses.

a. To calculate Tanya's gross income for the first year, we need to multiply the rent per month by the number of months the house was rented:

Gross income from rent = $620/month x 7 months = $4,340

Tanya also paid $175/month in average expenses for the whole year, so her total expenses were:

Total expenses = $175/month x 12 months = $2,100

Adding the mortgage interest paid, Tanya's gross income for the first year was:

Gross income = $4,340 + $3,600 = $7,940

b. To calculate Tanya's net income or net loss, we need to subtract her total expenses from her gross income:

Net income = Gross income - Total expenses

Net income = $7,940 - $2,100

Net income = $5,840

The number 2 is the one for which the theoretical probability matches the experimental probability.

To determine which number has a theoretical probability that matches the experimental probability, we need to calculate both the theoretical and experimental probabilities for each of the four numbers.

The theoretical probability of spinning any one of the four numbers is 1/4, or 0.25. This is because there are four equally likely outcomes, and each outcome has a probability of 1/4.

To calculate the experimental probability, we need to count the number of times each number was spun and divide by the total number of spins. Here are the results:

- Number 1 was spun 9 times out of 28 spins, so its experimental probability is 9/28, or approximately 0.321.

- Number 2 was spun 7 times out of 28 spins, so its experimental probability is 7/28, or approximately 0.250.

- Number 3 was spun 6 times out of 28 spins, so its experimental probability is 6/28, or approximately 0.214.

- Number 4 was spun 6 times out of 28 spins, so its experimental probability is 6/28, or approximately 0.214.

To find the number that has a theoretical probability that matches the experimental probability, we can compare the theoretical probability to each of the experimental probabilities. The number that has an experimental probability that is closest to the theoretical probability of 0.25 is number 2, which has an experimental probability of approximately 0.250.

Therefore, the number 2 is the one for which the theoretical probability matches the experimental probability.

The length of the guy wire should be option D √(25) ft. that is 25 ft.

Perpendicular means that two lines or objects intersect each other at a 90-degree angle, forming a right angle. This means that if you were to draw a line at the point of intersection, it would split the angles on either side of it into two equal parts. In simpler terms, if you imagine a horizontal line and a vertical line intersecting each other, they would be perpendicular to each other. The concept of perpendicularity is important in geometry and is used in many different applications, such as construction, engineering, and design.

We can use the Pythagorean theorem to find the length of the guy wire c. According to the theorem, in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. Therefore:

c² = a² + b²

Substituting the given values:

c² = (20 ft)² + (15 ft)²

c² = 400 ft² + 225 ft²

c² = 625 ft²

Taking the square root of both sides:

c = √(625) ft

c = 25 ft

Therefore, the length of the guy wire should be 25 feet.

The equation is given as y = -x + 8

The purpose of an equation is to find the value of the variable that makes the equation true. Equations are used in various fields of mathematics and science to represent relationships between different quantities and to solve problems.

To create an equation that represents the relationship between x and y in the table, we need to first determine the pattern or trend in the data.

From the given data, we can see that as x increases by 2, y decreases by 2. This suggests that there is a linear relationship between x and y.

Using the two points (-2,10) and (0,8), we can find the slope:

m = (y2 - y1) / (x2 - x1) = (8 - 10) / (0 - (-2)) = -1

Now that we have the slope, we can use any point on the line to find the y-intercept. Let's use the point (0,8):

With this strategy, the ball will travel approximately 28.98 meters horizontally before it hits the ground.

To solve this problem, we will need to find the time of flight and the horizontal velocity. We can use the following kinematic equations:

Vertical motion:

Maximum height: h = (v^2 * sin^2(angle)) / (2 * g)

Time of flight: t = 2 * v * sin(angle) / g

Horizontal motion:

Range: R = v * t * cos(angle)

Given:

Initial velocity (v) = 20 m/s

Angle = 45 degrees

Acceleration due to gravity (g) = 9.81 m/s²

Calculations:

Convert angle to radians: 45 degrees = 45 * (π/180) = 0.785 radians

Calculate time of flight: t = 2 * 20 * sin(0.785) / 9.81 = 2.04 seconds

Calculate horizontal range: R = 20 * 2.04 * cos(0.785) = 28.98 meters
