What is limf(x) where f(x) is as shown in the table

the distance from each chord to the center of the circle is 85 inches.

what is  chord ?

In geometry, a chord is a line segment that connects two points on the circumference of a circle. It is the straight line that intersects a circle at two points. In other words, a chord is a line segment that lies entirely inside the circle and connects two points on the circle.

In the given question,

If we draw a diagram of the circle with diameter 170 inches, we can see that the chords of length 26 inches divide the circle into two regions. We are interested in finding the distance from each chord to the center of the circle.

To solve this problem, we can use the following formula:

distance from chord to center = 1/2 * √(4r² - c²)

where r is the radius of the circle and c is the length of the chord.

First, we need to find the radius of the circle. The radius is half of the diameter, so:

r = 1/2 * diameter = 1/2 * 170 = 85 inches

Next, we can use the formula above to find the distance from each chord to the center of the circle. Plugging in the values we have:

distance from chord to center = 1/2 * √(4r² - c²)

distance from chord to center = 1/2 * √(4(85)² - 26²)

distance from chord to center = 1/2 * √(28,900)

distance from chord to center = 1/2 * 170

distance from chord to center = 85

Therefore, the distance from each chord to the center of the circle is 85 inches.

The percent increase in the cost of the uniform from last year to this year is 25%.

To find the percent increase in the cost of the uniform from last year to this year, we need to calculate the difference between the two prices, divide it by the original price, and then multiply by 100 to express the result as a percentage.

The difference between this year's price and last year's price is:

$65 - $52 = $13

The original price (last year's price) is $52.

So the percent increase in the cost of the uniform is:

percent increase = (difference / original price) x 100

percent increase = ($13 / $52) x 100

percent increase = 0.25 x 100

percent increase = 25%

Therefore, the percent increase in the cost of the uniform from last year to this year is 25%.

The useful computational shortcut for the ANOVA test is SSW = SST - SSB

therefore,option d. SSW = SST - SSB is correct.


ANOVA (Analysis of Variance) is a statistical test used to analyze differences between group means.

The test involves partitioning the total variation into two components:

variation between groups (SSB, sum of squares between) and variation within groups (SSW, sum of squares within).

The total sum of squares (SST) represents the overall variability in the dataset.

The computational shortcut for ANOVA states that the sum of squares within groups (SSW) can be calculated by

subtracting the sum of squares between groups (SSB) from the total sum of squares (SST).

So, SSW = SST - SSB.

Answer:

42 degrees

Step-by-step explanation:

So, first to find <QUT, which is a vertical angle, we have to figure out either QUR or TUS.  So:

9x+3=11x-27

solve for x:

x=15

Then, plug it into one of the equations.  Let's use 9x+3.

9(15)+3=138

So, we know that QUR is 138 degrees.

That means that TUS is ALSO 138.

138x2=276

Now we know that QUT and RUS have to equal whatever 360-276 is:

360-276=84

QUT and RUS have to equal 84 degrees, so we DIVIDE by 2.

84/2=42

So, QUT=42 degrees

Answer:

42 Degrees

Step-by-step explanation

Becuase (11x-27) and (9x+3) are vertical angles that means they are equal to each other

(11x - 27) = (9x + 3)

First you will add 27 to both sides

11x -27 = 9x +3

     +27         +27

Making it to:

11x = 9x + 30

Now you need to subtract 9x from both sides

11x = 9x +30

-9x   -9x

Turning it into this

2x= 30

Now Lastly, divide both sides by 2

2x = 30

2x     2x

And the answer is...... X=15

Now that you have the x value, we go back to the 11x-27 and replace the X with 15

11(15) -27 = 138 degress

Now because angle QUT and 138 degrees make a straight line that means together they will be 180 degress so you will subtract 180 by 138

Giving you the final answer of

42 Degrees

Area of sector GHJ ≈ 2.04 square units

Since we are given the central angle GHJ in degrees and the radius GH of circle H, we can find the area of sector GHJ using the formula:

Area of sector GHJ = (θ/360) × πr^2

where θ is the central angle in degrees and r is the radius.

Substituting the given values, we get:

Area of sector GHJ = (46/360) × π(4)^2

= (0.1278) × 16π

= 2.0448 square units

Rounding to the nearest hundredth, we get:

The height of the center of the Ferris wheel 51 m.

The height of capsule M is 51 m and the height of capsule T is 102 m.

Using this information, we can calculate the height of the center of the Ferris wheel, the height of capsule M, and the height of capsule T.

Height of the center of the Ferris wheel:

The center of the Ferris wheel is the midpoint of its diameter. Therefore, the height of the center of the Ferris wheel is half of the height of the top of the wheel above the ground.

Height of center of Ferris wheel = 102 meters / 2 = 51 meters.

Height of capsule M:

Since capsule M is at the same height as the center of the Ferris wheel, the height of capsule M is also 51 meters.

Height of capsule T:

Since capsule T is at the very top of the Ferris wheel, its height above the ground is equal to the height of the top of the Ferris wheel above the ground.

Height of capsule T = 102 meters.

A threat to internal validity occurs only if a potential design confound varies systematically with the independent variable.

In experimental research, an independent variable is a variable that the researcher manipulates or systematically varies in order to study its effect on the dependent variable. It is called "independent" because it is not influenced by any other variables in the experiment, and its effects on the dependent variable can be observed and measured independently of any other factors.

Only when a possible design confound fluctuates systematically with the independent variable does internal validity come under threat. In other words, it might be challenging to distinguish between the effects seen on the dependent variable and the independent variable if there is a component that fluctuates consistently or predictably with changes in the independent variable. Internal validity is less likely to be threatened by random or unplanned variation.

A threat to internal validity occurs only if a potential design confound varies systematically with the independent variable. This means that if the confound varies randomly or haphazardly, it is less likely to affect the results of the study.

This means that the confound is consistently related to the independent variable, making it difficult to determine if the observed effects are due to the independent variable or the confound. If the confound varies spontaneously or haphazardly, it is less likely to pose a threat to internal validity, as it would not be consistently associated with the independent variable.

However, if the confound is related to the independent variable in a consistent and predictable way, it can introduce bias and undermine the internal validity of the study. It is important for researchers to carefully control for potential confounds and ensure that any observed effects are truly due to the independent variable and not some other factor.

Trend component is easy to identify by using Moving average, Exponential smoothing, Regression analysis. So, correct options are A, B and C.

The trend component of a time series is a long-term movement in the data that represents a gradual increase or decrease over time. It is an important component of time series analysis because it can provide insights into the overall direction of the data and help forecast future trends.

One of the easiest ways to identify the trend component of a time series is by using a moving average. A moving average is a statistical method that calculates the average of a set of data over a specified period of time. By calculating the moving average, we can smooth out the short-term fluctuations in the data and identify the underlying trend.

Exponential smoothing is another method that can be used to identify the trend component of a time series. It is a forecasting technique that assigns exponentially decreasing weights to older observations, which places greater emphasis on more recent data.

This approach can help identify the trend by smoothing out the data and highlighting the underlying pattern.

Regression analysis can also be used to identify the trend component of a time series. It involves fitting a mathematical model to the data and identifying the relationship between the independent and dependent variables.

If the independent variable represents time and the dependent variable represents the data being analyzed, then regression analysis can help identify the trend component.

The Delphi approach is not typically used to identify the trend component of a time series. It is a forecasting technique that involves gathering expert opinions and using them to make predictions about future events.

In conclusion, the methods that are most commonly used to identify the trend component of a time series are moving average and exponential smoothing. Regression analysis can also be used in certain situations.

The result of subtracting 7.06 from 4.25 is -2.81.

Let's see how these steps apply to the problem at hand:

4.25

-7.06

In this case, we don't need to borrow because the top number 4.25 is already smaller than the bottom number 7.06.

Starting from the rightmost column, we subtract 5 from 6. Since 6 is larger than 5, we can subtract 5 from 6 and get 1. We write down 1 in the hundredths column.

Next, we move to the tenths column and subtract 2 from 0. We can't do this, so we need to borrow 1 from the digit in the ones column. The 4 in the ones column becomes 3, and the 2 in the tenths column becomes 12.

Now we can subtract 2 from 12, which gives us 10. We write down 0 in the tenths column and carry 1 to the ones column.

In the ones column, we have 3 - 7 - 1 (the borrowed 1) = -5. Since we can't have a negative number in this position, we need to borrow again from the digit in the tens column. The 2 in the tens column becomes 12, and we bring down the borrowed 1 to the ones column.

Now we can subtract 7 from 12, which gives us 5. We write down 5 in the ones column.

Step 4: Bring down any digits that have not been used.

We don't have any digits left to bring down, so we have finished the subtraction.

Therefore, the result of subtracting 7.06 from 4.25 is -2.81.

Answer: a)159 boxes of cereal will be sold during the 10th week, b) an = 15n + 9

Step-by-step explanation:

It takes the second marathoner 4 hours and 40 minutes to complete the marathon.

Let's assume the distance of the marathon is "d" miles.

The first marathoner runs at a constant speed for 4 hours, so we can find their speed as:

speed = distance / time = d / 4

The second marathoner starts by running at 4 times the speed of the first marathoner, so their speed is:

speed = 4(d / 4) = d

For the second half of the race, the second marathoner's speed drops to 3/4 of the first marathoner's speed. Let's assume it takes "t" hours for the second marathoner to complete the second half of the race. Then, we can write:

d / 2 = (3/4)(d / 4)(t)

Simplifying this equation, we get:

t = (2/3) hours

So the total time it takes the second marathoner to finish the race is:

Answer:

the pressure of the gas at a volume of 16 L would be 28 kPa.

Step-by-step explanation:

Using Boyle's Law:

P1V1 = P2V2

Where:

P1 = 112 kPa (initial pressure)

V1 = 4 L (initial volume)

V2 = 16 L (final volume)

Solving for P2:

P2 = (P1 x V1) / V2

P2 = (112 kPa x 4 L) / 16 L

P2 = 28 kPa

Therefore, the pressure of the gas at a volume of 16 L would be 28 kPa.

b) Initial conditions are a₀ = 0, a₁ = a₂ = 1

c) The number of messages sent in 12 microseconds are equal to 16.

A recurrence relation is an equation form for nth term of a sequence of numbers which is equal to some combination of the previous terms. We have a messages are sent over a communications channel using two different signals. Let an be different number of messages that can be transmitted in n microseconds. In case of First signal, it required 2 microsecondes time to tramissmit the signals. So, the different number of signals that can be transmitted in 2 microseconds are [tex]a_{n - 2} [/tex]

In case of second signal , Time required by second signal to to transmit signal = 3

microsecondes

So, different number of messages that can be transmitted in 3 microseconds are

[tex]a_{n - 3} [/tex]

Each signal of a message is transmitted one by one.

a) A recurrence relation for the number of different signals that can be sent in n microseconds is written as

[tex]a_n = a_{n - 2} + a_{n - 3}[/tex]

hat is an us sum of different signals transmitted by each signals.

b) recurrence relation is

The formula for the volume of a cylinder is V = πr²h,in which r= radius , h= cylinder height. Now we can rearrange formula by equating for r which gives the following formula:

V = πr²h

r² = V/(πh)

r = √(V/(πh))

By putting the values in the formula we can get:

r = √(490π/(π*10))

r = √49

r = 7

Therefore, the length of the radius is 7 inches.

Cylinder's volume can be viewed as the area that it takes up. It is computed by dividing the cylinder's height by the base's area, which is a circle. In this instance, we are informed that the height is 10 inches and the capacity is 490 cubic inches.
