Answer:

the median is 100

Step-by-step explanation:

the numbers are already in order so the number in the middle is 100.

The true statement about monthly income is "The family's monthly income must be less than $5,092." (option a).

The table provided shows the median income levels for different family sizes in various states, including Georgia. To determine whether the family of three is eligible for Chapter 7 bankruptcy, we need to compare their monthly income to the median income for a three-person family in Georgia, which is $61,104.

If the family's monthly income is less than the median income for their family size in their state, they are presumed to be eligible for Chapter 7 bankruptcy. In this case, the family's monthly income must be less than $61,104.

Looking at the table, we can see that the median income for a three-person family in Georgia is $61,104, which means that the family's monthly income must be less than $5,092 in order to be eligible for Chapter 7 bankruptcy.

Therefore, the correct answer is (a) - the family's monthly income must be less than $5,092 for them to be eligible to file for Chapter 7 bankruptcy.

Answer:

Let x be the width of the flag in feet. Then the length of the flag is x + 60 feet. The perimeter of the flag is the sum of the lengths of its four sides, which is:

2(x + x + 60) = 4x + 120 feet

Setting this equal to 480 feet, we have:

4x + 120 = 480

Solving for x, we get:

4x = 360

x = 90

Therefore, the width of the flag is 90 feet and the length is 150 feet.

Three situations to which this system of equations could be applied are:

A farmer wants to plant a rectangular field of flowers. He knows the perimeter of the field but needs to determine the length and width in order to calculate the area and decide how many flowers to buy.

A carpenter wants to build a rectangular frame for a painting. She knows the perimeter of the frame but needs to determine the length and width in order to calculate the amount of wood needed and the cost.

The critical points of h are -2 and 3

Recall that  a critical point of a function y = f(x) is a point (c, f(c)) on the graph of f(x) at which either the derivative is 0 (or) the derivative is not defined.

The given function is h(x) = [(x+2)(x-3)]

Finding the product of the brackets

(x+2)(x-3) = x²-3x+2x-6

Collecting like terms to have

h(x) = x²-x -6

h(x) = [(x+2)(x-3)] =  x²-x -6

factorizing this to get

(x²-3x)+(2x-6) = 0

x(x-3) + 2(x-3) = 0

x+2 = 0 or x-3 = 0

x=-2 or x = 3

Therefore the critical points are -2 and 3

The value of h is 0.895, the arc cosine of h is 0.462 and it terminates in the correct quadrant

Lastly, the measure of angle θ is 1.46 π

Given that

Terminal point = (-1.79, -0.89)

This means that

(x, y) = (-1.79, -0.89)

Also, we have

Radius, r = 2 units

So, the value of h is

h = |x|/r

This gives

h = |-1.79|/2

Evaluate

h = 0.895

In part (a) of this solution, we have

h = 0.895

Take the arc cos of both sides

So, we have

cos⁻¹(h) = cos⁻¹(0.895)

Evaluate the arc cos using a calculator

So, we have the following representation

h = 0.462 rad

This angle is in the first quadrant

It means that the angle terminates in the correct quadrant

For the value of θ, we have the following

This is calculated as

θ = π + tan⁻¹(-0.89/-1.79)

Evaluate

θ = π + 0.46 π

Answer:

1. w = [tex]\bold{e^{7+6x}}[/tex]

2. [tex]\bold{t = 2(log_a(7) - log_a(3))}[/tex]

Step-by-step explanation:

1.

a. The exponential form of a logarithmic equation is given by:

[tex]\bold{log_a(b) }[/tex]= c is equivalent to [tex]a^c = b[/tex]

Using this rule, we can rewrite the equation:

ln w = 7 + 6x as w = [tex]\bold{e^{7+6x}}[/tex]

Therefore, the exponential form of the given equation is w = [tex]\bold{e^{7+6x}}[/tex]

2.

a. To solve for t using a logarithm with base a, we can take the logarithm of both sides of the equation:

[tex]\bold{3a^\frac{t}{2} = 7 }\\\bold{log_a3a^\frac{t}{2}= log_a(7)}[/tex]

Using the rule of logarithms that log_a(b^n) = n*log_a(b), we can simplify the left side:

[tex]\bold{log_a(3) +\frac{t}{2} log_a(a) = log_a(7)}[/tex]

Since log_a(a) = 1 for any base a, we can simplify the expression further:

[tex]\bold{log_a(3) + \frac{t}{2}*1= log_a(7)}[/tex]

Now we can solve for t by isolating it on one side of the equation:

[tex]\bold{ \frac{t}{7} = (log_a(7) - log_a(3))} \\ \bold{t = 2(log_a(7) - log_a(3))}[/tex]

Therefore, the solution for t using a logarithm with base a is[tex]\bold{t = 2(log_a(7) - log_a(3))}[/tex]

Answer:

[tex]\textsf{1.} \quad w = e^{7 + 6x}[/tex]

[tex]\textsf{2.} \quad t= \log_a\left(\dfrac{49}{9}\right)[/tex]

Step-by-step explanation:

Exponential form is a way to represent a number using an exponent, where the base is raised to a power.

The natural logarithm function is the inverse of the exponential function:

[tex]\boxed{\ln x=y \iff x=e^y}[/tex]

Therefore we can use this definition to change the given equation to exponential form:

[tex]\begin{aligned}\ln w & = 7 + 6x\\\\e^{\ln w} & = e^{7+6x}\\\\w&=e^{7+6x}\end{aligned}[/tex]

Therefore, the exponential form of the equation is:

[tex]w = e^{7 + 6x}[/tex]

[tex]\hrulefill[/tex]

To solve for t using a logarithm with base a, begin by taking the logarithm of both sides of the equation with base a:

[tex]\log_a (3a^{\frac{t}{2}})=\log_a(7)[/tex]

[tex]\textsf{Apply the log product law:} \quad \log_axy=\log_ax + \log_ay[/tex]

[tex]\log_a (3)+\log_a(a^{\frac{t}{2}})=\log_a(7)[/tex]

Subtract logₐ(3) from both sides of the equation:

[tex]\log_a (3)+\log_a(a^{\frac{t}{2}})-\log_a (3)=\log_a(7)-\log_a (3)[/tex]

[tex]\log_a(a^{\frac{t}{2}})=\log_a(7)-\log_a (3)[/tex]

[tex]\textsf{Apply the log quotient law:} \quad \log_ax - \log_ay=\log_a \left(\dfrac{x}{y}\right)[/tex]

[tex]\log_a(a^{\frac{t}{2}})=\log_a\left(\dfrac{7}{3}\right)[/tex]

[tex]\textsf{Apply the log power law:} \quad \log_ax^n=n\log_ax[/tex]

[tex]\dfrac{t}{2}\log_a(a)=\log_a\left(\dfrac{7}{3}\right)[/tex]

Apply the log law:  logₐ(a) = 1

[tex]\dfrac{t}{2}(1)=\log_a\left(\dfrac{7}{3}\right)[/tex]

[tex]\dfrac{t}{2}=\log_a\left(\dfrac{7}{3}\right)[/tex]

Multiply both sides of the equation by 2:

[tex]2 \cdot \dfrac{t}{2}=2 \cdot \log_a\left(\dfrac{7}{3}\right)[/tex]

[tex]t=2 \log_a\left(\dfrac{7}{3}\right)[/tex]

Finally, apply the log power law:

[tex]t= \log_a\left(\dfrac{7}{3}\right)^2[/tex]

[tex]t= \log_a\left(\dfrac{7^2}{3^2}\right)[/tex]

[tex]t= \log_a\left(\dfrac{49}{9}\right)[/tex]

Therefore, the solution for t in terms of logarithm with base a is:

[tex]\boxed{t= \log_a\left(\dfrac{49}{9}\right)}[/tex]

An equation for f', the inverse function is: f¹(x) = (x - 3)/7, for x ≥ 4.

The equation is correct as it has been shown that f(f'(x)) = x and f'(f(x)) = x.

In Mathematics, an inverse function simply refers to a type of function that is obtained by reversing the mathematical operation in a given function (f(x)).

In this exercise, you are required to determine the inverse of function f. This ultimately implies that, we would have to swap (interchange) both the independent value (x-value) and dependent value (y-value) as follows;

f(x) = y = 7x + 3

x = 7y + 3

7y = x - 3

y' = f¹(x) = (x - 3)/7, for x ≥ 4.

Proof:

f(f'(x)) = f[(x - 3)/7] = 7[(x - 3)/7] + 3

f(f'(x)) = f[(x - 3)/7] = x - 3 + 3

f(f'(x)) = f[(x - 3)/7] = x.

f'(f(x)) = x

f'(f(x)) = f¹[(7x + 3)]

f'(f(x)) = (7x - 3 + 3)/7

f'(f(x)) = 7x/7

f'(f(x)) = x

What is a horizontal shift?

A horizontal shift is a type of transformation in which a function is shifted left or right along the x-axis without changing its shape or orientation. If a function f(x) is shifted to the right by a distance of c units, the resulting function is denoted by f(x - c), and if it is shifted to the left by a distance of c units, the resulting function is denoted by f(x + c). Horizontal shifts are commonly used in calculus, geometry, and other branches of mathematics to analyze the behavior of functions and to solve problems related to graphs and equations.

By plotting the inverse of the function the following graph is obtained.

We know that the function is x = -y² + 4.

The inverse of the function x = -y² + 4 would be y = , which is a vertical parabola opening upwards. When we use the horizontal line test, we find that any horizontal line would intersect the once, which means that a single input (x) would have single corresponding output (y). Therefore, the inverse of the function x = -y² + 4 is a function.

you will need 180 mL of the 55% alcohol mixture to create a 25% alcohol solution.

How to solve the question?

To find out how much of the 55% alcohol mixture is needed to create a 25% alcohol solution, we can use the formula:

(amount of pure alcohol in the 10% mixture + amount of pure alcohol in the 55% mixture) / total volume of solution = desired alcohol concentration

Let x be the amount of the 55% alcohol mixture needed.

First, we need to calculate the amount of pure alcohol in the 10% mixture. We know that the 10% mixture contains 10% alcohol, which means that there are 0.10 x 360 = 36 mL of pure alcohol in the mixture.

Next, we need to calculate the amount of pure alcohol in the 55% mixture. We know that the 55% mixture contains 55% alcohol, which means that there are 0.55 x x = 0.55x mL of pure alcohol in the mixture.

The total volume of the solution will be 360 mL + x mL.

Using the formula above, we can set up the equation:

(36 + 0.55x) / (360 + x) = 0.25

Simplifying the equation, we get:

36 + 0.55x = 0.25(360 + x)

36 + 0.55x = 90 + 0.25x

0.3x = 54

x = 180 mL

Therefore, you will need 180 mL of the 55% alcohol mixture to create a 25% alcohol solution.
