Hey there!
Linear functions have a continuous change.

Let's check these tables and see if we can tell linear functions from non-linear functions.

The first one is

- we add 1 each time

- we subtract 3 each time

\(\rule{200}{2}\)

Let's try the next one:

- we add 1 each time

- we add 5 each time

\(\rule{200}{2}\)

Let's try the third one:

        - we add 3, then 2, then 1..

So this table doesn't represent a linear function.

Let's check the fourth one:

- we add 1 each time

- we add 1 each time

Thus, Option C is the right option.

Hope everything is clear.

Answer:

0.22

Step-by-step explanation:

2/9 = 0.22

Given:

The equation is:

\(2540=\dfrac{22}{7}r^2(20)\)

To find:

The solution for the given equation.

Solution:

We have,

\(2540=\dfrac{22}{7}r^2(20)\)

It can be written as:

\(\dfrac{2540\times 7}{22\times 20}=r^2\)

\(\dfrac{17780}{440}=r^2\)

\(\dfrac{889}{22}=r^2\)

Taking square root on both sides, we get

\(\sqrt{\dfrac{889}{22}}=r\)               [Radius cannot be negative]

\(r=6.3568145\)

\(r\approx 6.36\)

Therefore, the value of r is about 6.36 cm.

To calculate the angle between the transmission axes of the two polarizers, we need to use the equation for the intensity of transmitted light through two polarizers:

I = I0 * cos^2(θ)

Where:

I is the intensity of transmitted light,

I0 is the initial intensity of unpolarized light incident on the first polarizer,

θ is the angle between the transmission axes of the two polarizers.

Given:

I0 = 65 W/m^2 (initial intensity of unpolarized light)

A = (1.0 cm)^2 (area of the photodiode)

E = 10 mJ (energy absorbed by the photodiode)

t = 4.0 s (exposure time)

To calculate the intensity I, we can use the formula:

I = E / (A * t)

Plugging in the given values:

I = (10 mJ) / [(1.0 cm)^2 * 4.0 s]

  = (10 × 10^(-3)) / [(1.0 × 10^(-2))^2 * 4.0]

  = 2.5 × 10^(3) / 4.0

  = 625 W/m^2

Now, we can equate the transmitted intensity I to the initial intensity I0 * cos^2(θ):

625 = 65 * cos^2(θ)

Dividing both sides of the equation by 65:

cos^2(θ) = 625 / 65

cos^2(θ) = 9.615

Taking the square root of both sides to solve for cos(θ):

cos(θ) = √(9.615)

θ ≈ arccos(√9.615)

θ ≈ 27.6 degrees

Therefore, the angle between the transmission axes of the two polarizers is approximately 27.6 degrees.

The probability of a standard normal random variable being larger than 0.7 is approximately 0.2420, or 24.20%.

To find the probability of a standard normal random variable being larger than a specific value, we can use the cumulative distribution function (CDF) of the standard normal distribution.

In this case, we want to find P(Z > 0.7), where Z is a standard normal random variable with mean 0 and standard deviation 1.

Using a standard normal distribution table or a calculator with the CDF function, we can find the probability associated with the value 0.7.

P(Z > 0.7) ≈ 1 - P(Z ≤ 0.7)

Looking up the value of 0.7 in the standard normal distribution table, we find that the corresponding cumulative probability is approximately 0.7580.

Therefore, P(Z > 0.7) ≈ 1 - 0.7580 ≈ 0.2420

Answer:

f(5) = -2

Step-by-step explanation:

Hello! So, when we have f(5), that is in the form of f(x). That means that our x = 5. Another thing to note is that f(x) is equivalent to our y-coordinate: the x-coordinate is the x value in the equation and the value is the f(x) in the equation.

Now we need to locate where x = 5 on the graph. When you find that, you need to see what point falls on x = 5. That points y-coordinate is your answer.

So if we look at x=5, the point (5, -2) falls on it. So f(5) = -2.

The probability that a randomly selected freshman has English as the first class of the day is 1/5 or 20%.

The expression that represents the conditional probability that a randomly selected freshman has English as the first class of the day is: p(E|Fr), where E represents English and Fr represents freshman.

To calculate this probability, we need to use the information from the two-way table. The total number of freshmen is given in the table as 150. The number of freshmen with English as their first class is 30.

So, the probability that a randomly selected freshman has English as the first class of the day can be calculated as:

p(E|Fr) = Number of freshmen with English as first class / Total number of freshmen

p(E|Fr) = 30 / 150

Simplifying the expression:

p(E|Fr) = 1/5

The length of the base of the rectangle is 11.9 yards if it has a perimeter of 57.6 yards.

We can determine the length of the base of the given rectangle by using the following for the perimeter as follows;

P = 2 ( L + W )

Here L represents length, W represents width and P represents the perimeter.

Since the height of the rectangle is 16.9 yards and we have to find the length of the base, the height can be considered to be the width of the rectangle. Therefore;

57.6 = 2 ( L + 16.9 )

57.6 = 2L + 33.8

2L = 57.6 - 33.8

2L = 23.8

L = 23.8 ÷ 2

L = 11.9

Therefore; the length of the base is calculated to be 11.9 yards.

Risk is the potential that a chosen action may lead to an undesirable outcome.

In simple terms, the definition of risk is a condition that is uncertain, but contains an element of danger as a consequence or result of something. Once again, this something is a business, business, activity, or decision that you make.

The risks themselves are divided into several types, complete with different characteristics.

1. Pure Risk 

This pure risk is certain, meaning that when the risk occurs, you will experience a loss. And vice versa, if pure risk does not occur, then you will make a profit.

2. Speculative Risk 

There are three possibilities that will happen, if you experience speculative risk, namely profits, losses, or maybe break even. What is meant by break even is the break even point.

Conditions where there are no profits or losses, so it's normal. The most obvious examples of speculative risk are the lottery, stock exchange, exchange risk, and others.

3. Particular Risk or Special Risk

Specific risks originate from individual activities, so the impact can still be estimated or anticipated at the outset because they are local in nature. For example, a turbine explosion, a shipwreck, or maybe a crash.

How to anticipate it (example for collision risk). You can take out insurance to provide guarantees or protection, both for the vehicle and for yourself.

4. Fundamental Risk 

Fundamental risks come from the surrounding environment or nature which can have quite a big impact, because humans are not able to control them.

To compare the two options, we need to calculate the total earnings for each option over the 4-year period.

Option 1: Earning an additional $500 each year

The total earnings for this option will be:

Year 1: $15,000

Year 2: $15,500 ($15,000 + $500)

Year 3: $16,000 ($15,500 + $500)

Year 4: $16,500 ($16,000 + $500)

Total earnings over 4 years = $15,000 + $15,500 + $16,000 + $16,500 = $63,000

Option 2: Earning 2% of current salary

To calculate the earnings for this option, we need to find the salary for each year using the formula:

salary = $15,000 + 2% × (previous year's salary)

Year 1: salary = $15,000

Year 2: salary = $15,300 ($15,000 + 2% × $15,000)

Year 3: salary = $15,606 ($15,300 + 2% × $15,300)

Year 4: salary = $15,924.12 ($15,606 + 2% × $15,606)

Total earnings over 4 years = $15,000 + $15,300 + $15,606 + $15,924.12 = $61,830.12

Therefore, the first option of earning an additional $500 each year results in higher total earnings of $63,000 over 4 years, compared to earning 2% of the current salary, which results in total earnings of $61,830.12. Hence, the first option of earning an additional $500 each year is the better choice.

We know that the x intercepts of a function are given when y = 0

like the function of this figure, that intercepts x axis on the blue points.

Then, we want to know the values of x that makes y = 0:

y = 3x² + 18x + 27

↓

0 = 3x² + 18x + 27

We want to find GCF of the terms of the addition:

0 = 3x² + 18x + 27

Since

3 · 6 = 18 and 3 · 9 = 27, we can write:

0 = 3x² + 18x + 27

↓

0 = 3 · x² + 3 · 6x + 3 · 9

Then, the GCF of the terms of the addition is 3. So we can write:

0 = 3 · x² + 3 · 6x + 3 · 9

↓

0 = 3(x² + 6x + 9)

We want to write

x² + 6x + 9 = (x + _ ) (x + _ )

in order to do so we must find the numbers that fill the space.

This couple of numbers satisfy that:

1- their addition is the second term, 6.

2- their product is the last term, 9.

We have that

3 + 3 = 6

and

3 · 3 = 9

Then, the numbers are 3:

x² + 6x + 9 = (x + 3 ) (x + 3) = (x + 3)²

Since we have factored completely the equation, we have

3x² + 18x + 27 = 3(x + 3)²

then

3(x + 3)² = 0

We have that this product is zero, 0, iff

(x + 3) = 0

If

x = -3

then

x + 3 = 0

Then

when x = -3, then y = 0

Therefore,

when x = -3, the function intercepts x:

Answer: when x = -3, the function intercepts x.

With a mean of 82 and a standard deviation of 5, the random variable x has a normal distribution. The stated probability is roughly 0.3446, or 34.46%.

To find the probability P(x < 80) for a normally distributed random variable with mean μ = 82 and standard deviation σ = 5, we need to calculate the area under the normal curve to the left of the value x = 80.

We can standardize the variable x using the formula z = (x - μ) / σ, where z is the standard score. In this case, x = 80, μ = 82, and σ = 5, so we have:

z = (80 - 82) / 5 = -2 / 5 = -0.4

Now, we need to find the cumulative probability associated with the z-score -0.4. This represents the probability of obtaining a value less than x = 80.

We may determine the associated cumulative probability using a calculator or a basic normal distribution table.

According to a conventional normal distribution table, the cumulative probability for -0.4 is around 0.3446.

Therefore, P(x < 80) ≈ 0.3446.

So, the indicated probability is approximately 0.3446 or 34.46%.

Step-by-step explanation:

The correct answer is 4 km per hour Lashonda would swim if there were no current.

Here, we'll suppose that Lashonda is moving at x km/hr. in the absence of any current.

Speed of the current is 2 km/hr.

Distance swim against current is 5km

Time taken to swim against current is  5 ÷ (x - 2)

Distance swim with current is 15km

Time is taken to swim with current is 15 ÷ (x + 2)

Now,

Given that  if the time taken in both instances are the same, So, the equation will be 5 ÷ (x - 2) = 15 ÷ (x + 2)

After solving for x we will be solving;

⇒ 5 ÷ (x + 2) = 15 ÷ (x - 2)

⇒ 5x + 10 = 15x - 30

⇒ 10 + 30 = 15x - 5x

⇒ 40 = 10x

⇒ x= 40 ÷ 10 = 4 km per hour

Hence, 4 km per hour Lashonda would swim if there were no current.
