ASAP!! Which one is not an irrational number? I believe it’s A but I just want to double check.

The value of x that will make the two given solids similar is: d. x = 31.

If two solids are said to be similar to each other, it means that one is a scale copy of the other, and one is enlarged by a scale factor to get the dimension of the other.

Thus, the corresponding linear dimensions of two similar solids are proportional or they have equal ratio.

Based on this definition, the equation below would be created to find the value of x that would make both solids similar to each other.

29/14.5 = x/15.5

Cross multiply:

14.5x = (15.5)(29)

14.5x = 449.5

14.5x/14.5 = 449.5/14.5

x = 31.

If the profit function is P(x) = 13x - 741 then the units that must be produced to break even is 57 units.

What is a profit function?

The difference between income and costs is referred to as profit. A relationship that depicts the difference created by subtracting the cost function from the revenue function is called a profit function. The ideal pairing of revenues and expenses to generate the greatest possible profit can be seen on the graph of a profit function.

Here, we have

Given

R(x) = 16x (The revenue function)

C(x) = 3x + 741 (The cost function)

Profit = Revenue - Cost

P(x) = 16x - 3x - 741

P(x) = 13x - 741

Hence, the profit function P(x) is  13x - 741.

For the company to break even, R(x) = C(x)

16x = 3x + 741

13x = 741

x = 57

Hence, if the profit function is P(x) = 13x - 741 then the units that must be produced to break even is 57 units.

The ordered pair that lie on the graph as per the equation will be equal to (-2, -4). Hence, option B is correct.

In math, graph science is the theory of geometric structures called graphs that are used to represent pairwise different objects. Vertices—also known as nodes or points—that are joined by edges make form a network in this sense.

Undirected graphs, where edges connect two vertices equally, and focused therapy, where edges connect two vertices unevenly, are distinguished.

As per the given information in the question,

The given equation is,

f(x) = 2(x + 4) - 8

Let's check as per the points given in the question,

A. (24, 1)

f(x) = 2(24 + 4) - 8

f(x) = 48

So, the supplied exponential function's graph does not contain the point (24, 1) mentioned.

B. (-2, -4)

f(x) = 2(-2 + 4) - 8

f(x) = 4 - 8

f(x) = -4

As a result, the points (-2, -4) are located on the graph of the supplied exponential function.

C. (2, 256)

f(x) = 2(2 + 4) - 8

f(x) = 4

So, the supplied exponential function's graph does not contain the point (2, 56) mentioned.

Answer:

A. Yes, but only within the domain x ≥ 0

Step-by-s+tep explanation:

What you need to know to solve the question:

1. To find an inverse function (f⁻¹(x)) of f(x), rearrange the equation in terms of f(x), in other words, it should be in the form of x = ...

2. Rules of rearranging equations

3. The domain of √x is: x ≥ 0, since you cannot find the square root of a negative number (i.e. < 0)

Find the inverse function of F(x):

According to principles 1 and 2:

F(x) = √x - 6

F(x) + 6 = √x

(F(x) + 6)² = x

x = (F(x) + 6)²

So, the inverse function is:

F⁻¹(x) = (x + 6)²

And since:

G(x) = (x + 6)²

G(x) = F⁻¹(x)

Therefore, the answer is, also in light of principle 3:

A. Yes, but only within the domain x ≥ 0

y = 3x + 5 is a linear relationship with a slope of 3.

A straight line is formed on the graph by the equation y=2x+1, which is a linear equation. The value of y eventually rises by twice the value of x + 1. This happens when the value of x grows.

A linear graph is one that displays a single straight line for each given relation. A straight line is what the word "linear" denotes. A straight line graph linking points displayed on x and y coordinates is known as a linear graph.

A linear non - proportional relationship could be written with as a slope - intercept with a non - zero intercept value. One such relationship with a slope of 3 can be expressed thus :

y = 3x + 5

Here, the linear relationship, has a slope value of 3 and an intercept value of 5. The function cannot be proportional due to the presence of a non-zero constant

Hence, Using a graphing calculator, the sketch of the linear relationship is attached.

To solve the system of differential equations using Theorem 1, we first need to find the eigen values and eigen vectors of the matrix X'.

The characteristic equation is given by |X' - λI| = 0, where I is the identity matrix. Solving this equation, we find the eigenvalues to be λ = -2, 0, 3, 5.

Next, we need to find the corresponding eigenvectors. For each eigenvalue, we solve the equation (X' - λI)v = 0 to find the eigenvector.

For λ = -2, the eigenvector is v = [-2 -2 -2 -2 -2 1 -2 -2 -2 -2 -2 1 -2 -2 -2 1]

For λ = 0, the eigenvector is v = [-4 1 -2 -2 4 -3 2 -2 1 -2 -5 0 1 0 4 -1]

For λ = 3, the eigenvector is v = [4 -2 -2 -2 -4 3 -2 -2 -1 -2 5 0 -1 0 -4 1]

For λ = 5, the eigenvector is v = [0 2 2 2 0 -1 2 2 2 2 0 -1 2 2 0 -1]

Using these eigen values and eigen vectors, we can use Theorem 1 to find the general solution to the system of differential equations:

X(t) = c1e^(-2t)v1 + c2e^(0t)v2 + c3e^(3t)v3 + c4e^(5t)v4

where c1, c2, c3, and c4 are constants.

To show that this solution solves the original system of differential equations, we substitute it into the given differential equation:

X'(t) = -2c1e^(-2t)v1 + 0c2e^(0t)v2 + 3c3e^(3t)v3 + 5c4e^(5t)v4

This simplifies to:

X'(t) = [-4 0 0 0 8 -3 4 0 1 0 -5 0 2 1 4 -1 ]

which is equal to the given matrix X'(t). Therefore, the solution we have found does indeed solve the original system of differential equations.

m and n are integers such that mn is even, but m and n are both odd. This contradicts the assumption that mn is even, so we must conclude that either m is even or n is even.

Proof:

Assume m and n are integers such that mn is even and m is not even and n is not even.

However, since the product of two odd integers is always odd, this contradicts the assumption that mn is even.

Therefore, it must be true that m is even or n is even.

We assume that m and n are integers such that mn is even, but m and n are both odd. This contradicts the assumption that mn is even, so we must conclude that either m is even or n is even. This is a proof by contraposition, meaning that we have assumed the opposite of what we want to prove and showed that this is not true. This in turn implies that the original statement is true, and so we have proven that if mn is even, then m is even or n is even.

The standard deviation is a measure of how much the values of a random variable tend to vary from the mean of the variable. In this case, the standard deviation of the random variable W is 3.5, which means that the values of W typically vary from the mean of 4 by about 3.5 attempted experiments. Therefore, the best interpretation of the standard deviation, in this case, is that values of W typically vary from 4 by about 3.5 attempted experiments, on average.

To answer (b), we first need to calculate the z-score for 86.3 cm using the population mean of 85 cm and standard deviation of 14 cm. This gives us a z-score of 0.7. We can then use the normal distribution table to calculate the probability of a sample mean of at least 86.3 cm with a z-score of 0.7, which is 0.9982. To answer (c), we need to calculate the z-score for 86.3 cm using the population mean of 80 cm and standard deviation of 14 cm. This gives us a z-score of 1.5. We can then use the normal distribution table to calculate the probability of a sample mean of at least 86.3 cm with a z-score of 1.5, which is 0.9817.

Part (b):

Z-score = (86.3 - 85) / 14
