The value of the function given as (f . g)(2) is D. (f.g)(2) = 44, the number of boats

It's important to note that functions are the expressions that are separated by an equal sign. It should be noted that that they've dependent as well as independent variables.

In this case, the function f(x)=2x²+3 represents the rate of a boat traveling with the current in miles per hour and the function g(x)=x+ 2 represents the time the boat traveled in hours. This will be illustrated as:

f(x) = 2x² + 3.

g(x) = x + 2

Therefore, we will evaluate the product

(f . g)(x) = (2x² + 3(x + 2)

(f . g)(x) = (2 × 2² + 3)(2 + 2)

(f . g)(2) = 44

The correct option is D.

Answer:

Step-by-step explanation:

alternate interior

Answer:

b) The stock is 5.5 less than the original value, and the absolute value is 5.5.

Step-by-step explanation:

First of all, let's make our number line. The question says you need it to start at -9, so we can assume that it will go until 10. It also wants us to make half-tick marks. (There is an image attached of the number line.)

It says that -5.5 is labeled, so do that on your number line.

Next, it explains that 0 is the original price. 0 is where the stock is starting at. This does not mean that the value of the stock is 0!!! (It means that NO MATTER what the price of the stock is, that is now considered 0.)  

Now for the multiple choice, here's why all the answers are incorrect/correct.

a) If something is -5.5 less, it's the same as subtracting a negative number- which makes it positive!! SO this would mean that it added value.

b) Correct! Since it value is lower by 5.5, it's 5.5 less than the og value.

c) Since it's -5.5 greater, that's like adding a negative number: it's the same as subtracting. I suppose this is technically correct, but it's weird.

d) This one says's it's 5.5 greater, which is totally wrong. The value is decreasing, not increasing!

All of them say the absolute value is 5.5. This is correct. Absolute value is the distance from 0, and -5.5 is 5.5 units away from 0. (put simply, absolute value is just making the number positive.

hopefully this makes sense and helps you!!

With the bottom of the Ferris Wheel being 5 meters off the ground, and a radius of, r = 7.5 meters, the center of the Ferris Wheel is 12.5 meters off the ground.

A horizontal  line through the center of the Ferris Wheel is 12.5 meters off the ground, and therefore the lower half of the Ferris Wheel is always below 14 meters.

The distance from the horizontal to 14 meters is 1.5 meters (14 - 12.5), and angle between the horizontal and a radius to 14 meters is sin(θ) = 1.5/7.5 or θ = sin-1(1.5/7.5) = 11.54o. This angle height is on both sides of the Ferris Wheel and therefore 180o + 2*11.54o = 203.07o is always under 14 meters. What is above 14 meters is 360o - 203.07o = 156.93o.

Since it takes 8 minutes for 1 revolution, (156.93o/360o)*8 min ≈ 3.5 min, the amount of time the Ferris Wheel is above 14 meters.

Answer: 1 knife costes £5.52

Step-by-step explanation:

Let a knife costes £x and a spoon costes £y

Hence, we obtain a system of equations:

x=3y                         (1)

12x+9y=82.80         (2)

Divide both parts of the equation (2) by 3:

x=3y                    

4x+3y=27.6        (3)

We substitute the value of x=3u into equation (3):

4(3y)+3y=27.6

12y+3y=27.6

15y=27.6

Divide both parts of the equation by 15:

y=£1.84

x=3y

x=3(1.84)

The z-score corresponding to an observation is -1.02

From the given data μ=335

X=284

It is a way to compare the results from a test to a “normal” population.

If X is a random variable from a normal distribution with mean (μ) and standard deviation (σ), its Z-score may be calculated by subtracting mean from X and dividing the whole by standard deviation.

Where, x = test value

μ is mean and

σ is SD (Standard Deviation)

For the average of a sample from a population ‘n’, the mean is μ and the standard deviation is σ.

X=284 now we have to find Z score

so from the formula the Z score corresponding to observation X=284 is we have

Z=X- μ/σ

If a lawyer charges 120 an hour then the bill for 3 hours and 20 minutes will be 400

Bill: A bill is the printed or written statement of the money owed for goods or services.In later Latin, bulla became billa, and in English billa became bill. The word can still refer to various official documents, such as a proposed law that is brought before parliament, although it is now most commonly used for documents that request payment of money.

One hour = 60 minutes

3 hours and 20 minutes = 3×60 +20

                                        = 180+20=200

Here, one hour=60 minutes charges 120

1 minute charges = 120/60

Step-by-step explanation:

Only answers A, C, and D are in standard form, so we can rule B out immediately.

If you throw (5,1) into A, you get:

   5(5) - 2(1) = 23

        25 - 2 = 23

The amount of tax that Eric and Maria will pay on their dividend income is 24% so 24% * $3,000 = $720. This amount will then be added to their taxable income of $88,910, and the resulting amount will be used to calculate the total tax they owe for the year.

The amount of tax that Eric and Maria will pay on their dividend income will depend on their marginal tax rate. In 2021, the federal tax rate is progressive, meaning that the higher their taxable income, the higher their marginal tax rate. For a taxable income between $80,251 and $171,050, the marginal tax rate is 24%. Therefore, the tax that Eric and Maria will pay on their dividend income will be 24% of the amount of dividend income they received. This amount will then be added to their taxable income of $88,910, and the resulting amount will be used to calculate the total tax they owe for the year.

Answer:

x-intercept is (10,0)

y-intercept is (0, -8)

Step-by-step explanation:

Our equation is 4x - 5y = 40

Let's find x-intercepts first

X-intercepts is when the y = 0

So we put 0 in for the y, and we have the equation

4x =40

x =10

So our x-intercept located at (10,0)

Now find the y-intercepts

Y-intercepts is when the x = 10

So we put 0 in for the x, and we have the equation

-5y = 40

y= -8

So our y-intercept is located at (0,-8)

Answer:

Step-by-step explanation:

Y-int: (0, -8)

X-Int: (10, 0)

To find the y and x intercepts you have to plug in the 0 for the variable. You'd get 4(0)-5y=40 you get this by plugging in the 0 for x and then you solve. 4 x 0 is 0 so you'd get -5y=40 divide -5 on both sides and get y=-8 meaning that is the y-intercept.

You'd do the same when you look for the x-int. Just that you'd plug in a 0 for y instead of x. Which is 4x-5(0)=40. -5 x 0 is 0. So you'd have 4x=40 divide both sides by 4 and you'd get x=10 meaning that is the x intercept.

Remember that when looking for the y- intercept there should always be a zero in front meaning the x-value, and when looking for the x-intercept there should always be a  zero in the back meaning the y-value.

(Hopefully you were able to understand how I got the x and y intercepts for this equation)

To make x the subject of the equation q^2 = x - m^2, we can start by adding m^2 to both sides of the equation:

q^2 + m^2 = x

We can then rearrange the terms to get x on the left side:

x = q^2 + m^2

This is the equation with x as the subject.

Answer:

  y = (4 -x)e^-2

Step-by-step explanation:

You want an equation of the tangent line to the graph of f(x) = xe^−x at its inflection point.

The inflection point on a curve is the point where the second derivative is zero, where the curve changes from being concave downward to concave upward, or vice versa.

We can use the product rule to differentiate f(x):

  (uv)' = u'v +uv'

  f'(x) = 1·e^-x +x·(-1)(e^-x) = (e^-x)(1 -x)

Then the second derivative is ...

  f''(x) = (-e^-x)(1 -x) +(e^-x)(-1) = (e^-x)(x -2)

The second derivative is zero where one of its factors is zero. e^-x is never zero, so we have ...

  (x -2) = 0   ⇒   x = 2

The point of inflection occurs at x = 2.

The point-slope equation of the line with slope m through point (h, k) is ...

  y -k = m(x -h)

For this problem, we have ...

  m = f'(2) = (e^-2)(1 -(2)) = -e^-2

  (h, k) = (2, f(2)) = (2, 2e^-2)

So, the equation of the tangent line is ...

  y -2e^-2 = -e^-2(x -2)

In slope-intercept form, this is ...

  y = (-e^-2)x +4e^-2

__

Additional comment

We can rearrange the equation to ...

  y = (4 -x)e^-2

Usually a tangent line touches the graph, but does not cross it. The tangent at the point of inflection necessarily crosses the graph.

the three vectors are linearly dependent and they cant generate a 3 dimensional vector subspace.

Lets take v1 = (1,0,0), v2 = (1,1,0) and v3 = (0,1,0). Neither of the vectors are a multiple of the other, however they dont generate R³ because for example the vector (0,0,1) is not a linear combination of v1, v2 and v3.

Not that, despite not being a multiple of v1 or v3, v2 is a linear combination of v1 and v3, because it is the sum of both of them. Therefore, the three vectors are linearly dependent and they cant generate a 3 dimensional vector subspace.

The population means may be the same

So, option D is correct.

What is meant by confidence interval?

In statistics, the probability that a population parameter will fall between a set of values a predefined percentage of the time is known as the confidence interval. Analysts typically use confidence intervals that cover 95% or 99% of the expected observations while assessing data. In frequentist statistics, an estimation range for an unknown parameter is referred to as a confidence interval. The most common confidence level for computing confidence intervals is 95%, however other levels, such 90% or 99%, are also occasionally employed. The conclusion is reached that the result is statistically significant if the confidence interval eliminates the value of zero effect.

If (μ₁- μ₂=0) is included in the confidence interval, that means this two means have the same difference that is zero.

Therefore, they may be nearly same,
