What is
3x - 4 (2x5) = 2 (x-1) + 5/2

The number of horizontal asymptotes that graph of y = f(x) can have is (c) 2.

As x approaches negative infinity, the function f(x) approaches the horizontal-asymptote y = 0 because the term 1/x becomes negligible compared to other terms. This occurs in the portion of the function defined as 1/x when x < 0.

As x approaches positive infinity, the function f(x) approaches the horizontal-asymptote y = 2 because the term 2x becomes dominant compared to other terms. This occurs in the portion of the function defined as 2x - 1 when x ≥ 0.

Therefore, the graph of y = f(x) has two horizontal asymptotes: y = 0 as x approaches negative infinity and y = 2 as x approaches positive infinity. The correct answer is (c) 2.

Answer: $0.07 and $0.08

Step-by-step explanation: 1. To find the price per square inch of a 16 inch pizza for $14, we need to first calculate the area of the pizza.

The formula for the area of a circle is A = πr^2, where r is the radius of the circle. In this case, the radius is half of the diameter, which is 8 inches.

So, the area of the pizza is A = π(8)^2 = 64π square inches.

The price per square inch is the total price divided by the area of the pizza:

Price per square inch = Total price / Area

Price per square inch = $14 / (64π) square inches

Price per square inch ≈ $0.07

Therefore, the price per square inch of a 16 inch pizza for $14 is approximately $0.07.

Answer: $0.07

2. Following the same method as above, for a 14 inch pizza for $12, the radius is 7 inches and the area is A = π(7)^2 = 49π square inches.

The price per square inch is:

Price per square inch = Total price / Area

Price per square inch = $12 / (49π) square inches

Price per square inch ≈ $0.08

Therefore, the price per square inch of a 14 inch pizza for $12 is approximately $0.08.

Answer: $0.08

Therefore, function of x f(f(2)) = f(-3) = 9

To find  function of f f (2) we need to find the function f(2).

Given  f(3x - 1) = -6x + 3

Let  3x -1 = 2  we will get

3x =3

x =1

Therefore, let input x =1

f(3x - 1) = -6x + 3

f(3(1) - 1) = -(1) + 3

Therefore, we need to find function of f(-3) and get  f f (2).

f f (2). =f(-3) =9

f(3x - 1) = -6x + 3

f(-3) = -6(-1) + 3 =9

Therefore, if f(3x - 1) = -6x + 3, function of f(f(2)) = f(-3) = 9

The probability of the arrow landing on section a is 1/5 since there are 5 equal sections. The probability of the coin landing on heads is 1/2 since there are only 2 possible outcomes (heads or tails) for the coin.

To find the probability of both events happening, we need to multiply the probability of the arrow landing on section a by the probability of the coin landing on heads. This gives us (1/5) * (1/2) = 1/10. So the probability that the arrow will land on the section labeled a and the coin will land on heads is 1/10. In other words, there is a 1 in 10 chance of both events happening. It is important to note that each event is independent of each other, meaning the outcome of one does not affect the other. This is because the spinner and the coin are not connected or related in any way.

The angle between the normal to the diaphragm and a line to the first minimum in the diffraction pattern is approximately 9.43 degrees

To find the angle between the normal to the diaphragm and a line to the first minimum in the diffraction pattern, we can use the concept of diffraction and the formula for the angle of the first minimum in a single-slit diffraction pattern:

sin(θ) = λ / (diameter)

where θ is the angle, λ is the wavelength of the sound, and the diameter is the diameter of the diaphragm.

First, let's convert the frequency of 15.69 kHz to the corresponding wavelength using the formula:

wavelength = speed of sound / frequency

wavelength = 1450 m/s / (15.69 kHz * 1000 Hz/kHz)

wavelength = 0.09257 meters (rounded to five decimal places)

Next, we can substitute the values into the formula to find the angle:

θ = [tex]sin^{(-1)}[/tex] (0.09257 meters / 0.5806 meters)

θ ≈ 9.43 degrees (rounded to two decimal places)

Therefore, the angle between the normal to the diaphragm and a line to the first minimum in the diffraction pattern is approximately 9.43 degrees. This angle represents the bending or spreading of the sound waves as they pass through the circular hole of the diaphragm, creating the diffraction pattern.

There are two ways you could approach this.

The first is to solve each inequality separately and see which one ends up equal to x ≥ -1.

Another and faster option is to test 0 in each inequality, because 0 is in the solution set and 0 is easy to work with.  (You could do this for any value in the solution set.)

A: Is 4(0) + 3 > 7 true?  No.  3 > 7 is false.  This eliminates A.

B. Is 0/3 - 2 ≥ 2 true?  No.  -2 ≥ 2 is false.  This eliminates B.

C. Is -2(0) - 3 ≤ -1 true?  Yes.  -3 ≤ -1 is false.  We cannot eliminate C.

D. Is 0 + 5 < 4 true?  No.  5 < 4 is false.  This eliminates D.

So based on using x=0, the only possible solution is C.

You can double check this by solving 2x - 3 ≤ -1 for x:

    -2x - 3 ≤ -1

         -2x ≤ 2  (by adding 3 to both sides)

Now when you divide by -2 to solve for x, remember to flip the inequality.

The standard deviation is approximately 24.28 units.

1. The standard deviation can be calculated using the formula for the normal distribution:

P(X > 250) = 0.05

Using a standard normal distribution table, we can find the corresponding z-score for a probability of 0.05, which is approximately 1.645.

z = (250 - 210) / σ

Solving for σ, we get:

σ = (250 - 210) / z = (250 - 210) / 1.645 = 24.28 units

Therefore, the standard deviation is approximately 24.28 units.




To determine the standard deviation of a normally distributed pollutant concentration in a lake, we first use the probability of exceeding 250 units (0.05) and a standard normal distribution table to find the corresponding z-score (1.645).

The probability of a type i error for a sample of size 10 depends on the significance level (α) chosen for the hypothesis test. Assuming a standard significance level of 0.05, the probability of a type i error for a sample of size 10 can be calculated using a t-distribution table or a statistical software.

A type i error occurs when a null hypothesis is rejected when it is actually true. In hypothesis testing, the significance level (α) is the probability of rejecting the null hypothesis when it is actually true. A common significance level used in statistical analysis is 0.05, which means that there is a 5% chance of rejecting the null hypothesis when it is actually true.

The probability of a type i error for a sample of size 10 can be calculated using a t-distribution table or a statistical software. The calculation involves finding the critical value of t at the chosen significance level and degrees of freedom (df), which is equal to the sample size minus 1 (n-1). For a sample size of 10 and a significance level of 0.05, the critical value of t is approximately 2.306 (from a t-distribution table with 9 degrees of freedom).

To calculate the cliff's elevation in 10 millennia, we need to use a little bit of math.

Since the cliff is losing elevation at a rate of 5% every millennium, we know that after one millennium, the cliff's elevation will be 95% of its current elevation. Therefore, we can use this formula to calculate the cliff's elevation after three millennia:
1,519 meters * 0.95^10 = 601.83 meters
So, after 10 millennia, the cliff's elevation will be approximately 601.83 meters. This means that the cliff will have lost approximately 917 meters of elevation over the course of 10,000 years due to erosion.

According to the statement the probability of getting either a head or an even number on the die is 3/4.

To calculate the probability of getting a head or an even number, we can use the formula for the probability of the union of two events:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
In this case, A represents getting a head, and B represents getting an even number on the die.
P(A) = Probability of getting a head = 1/2 (since there are two sides of the coin: heads and tails)
P(B) = Probability of getting an even number on the die = 3/6 (since there are three even numbers out of six possible outcomes: 2, 4, and 6)
P(A ∩ B) = Probability of getting both a head and an even number. Since these two events are independent, we can find this probability by multiplying the individual probabilities: P(A) * P(B) = (1/2) * (3/6) = 1/4
Now, we can find the probability of the union:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B) = (1/2) + (3/6) - (1/4) = 1/2 + 1/2 - 1/4 = 3/4
