The value of the expression given as √x³ is x√x

The expression is given as

√x³

Express 3 as the sum of 2 and 1

So, we have the following equation

√x³ = √x²⁺¹

Apply the law of indices to expand the equation

So, we have the following equation

√x³ = (√x² * √x)

Next, we expand the equation

So, we have the following equation

√x³ = √x² * √x

Evaluate the square root of x²

So, we have the following equation

√x³ = x * √x

Evaluate the product

So, we have the following equation

√x³ = x√x

Hence, the value of the expression is x√x

If He rides back home, taking the same route, on a bus that travels at a rate of 40mi/hr. The entire trip takes 3.5 hrs. How far along this route is Terrence’s house from the theater is : 50 mile.

Movie time = 2hrs and 15mins

Let convert the movie time

2hrs and 15mins = 2 15/60 h = 2 1/4 h = 2.25 h

Now let calculate the bus time and the distance

Bus time = Entire time - Walking time

Bus time = 3.5 h - 2. 25 h

Bus time =  1.25 h

Now let calculate the distance

Distance = Speed × Time

Distance =  40mi/hr ×  1.25 h

Distance = 50 mile

Therefore the distance is 50 mile.

The quota sampling produces the same advantages for convenience sampling that stratified random sampling produces for probability sampling.

Sampling:

Sampling is defined as the process in statistical analysis where researchers take a predetermined number of observations from a larger population.

Given,

Here we need to find the type of sampling that produces the same advantages for convenience sampling quota sampling.

Before, move on to the result, first we have to know the details about quota sampling and the probability sampling.

Probability sampling defined as the selection of a sample from a determined number of population, when this selection is based on the principle of randomization, that is, random selection or chance.

In contrast to probability sampling, Quota sampling means a non-probability sampling method in which researchers create a sample involving individuals that represent a population.

Based on these definition we have identified that the method that is best suitable answer for this one is stratified random sampling.

Because the stratified random sampling means, is a probability sampling technique in which the total population is divided into homogenous groups to complete the sampling process.

Answer:

f ( 5, 2 )

h ( 4, -2 )

a ( 1,0 )

d ( -3, 5 )

Step-by-step explanation:

Assuming every point is one space.

We can find this by counting how far away it is form the origin for example f is 5 place right of the origin so x=5 and is above the origin two places so y=2. So (5,2) is the answer.

The function f,g and h are defined by f(x)=xSin(1/x²), g(x)=x²Sin(1/x) and h(x)=Sinx/x. The 1st and 2nd inequality are satisfying the function, Option A is correct.

Given that,

The function f,g and h are defined by

f(x)=xSin(1/x²)

g(x)=x²Sin(1/x) and

h(x)=Sinx/x

We have to find which inequality can be used with squeeze theorem to find the limit of the function.

The inequality are

1. -|x|<f(x)<|x|

2. -x²<g(x)<x²

3. -x<h(x)<x

The squeeze (or sandwich) theory states that if f(x)g(x)h(x) for all numbers and at some point x=k we have f(k)=h(k), then g(k) must also be equal to them. Theorem: We can use them to achieve challenging limits, such as sin(x)/x at x=0, by "squeezing" sin(x)/x between two better functions and using them to find the limit at x=0.

First we see the 1st inequality.

The range of sin function is from -1 to 1

-1<Sin(1/x²)<1

-x<xSin(1/x²)<x

-|x|<xSin(1/x²)<|x|

-|x|<f(x)<|x|
The 1st inequality satisfy the function.

Now, we see the 2nd inequality.

The range of sin function is from -1 to 1

-1<Sin(1/x)<1

-x²<x²Sin(1/x²)<x²

-x²<g(x)<x²
The 2st inequality satisfy the function.

Now, we see the 3nd inequality.

The range of sin function is from -1 to 1

-1<Sinx<1

-1/x<Sinx/x<1/x

-1/x<h(x)<1/x
The 3st inequality does not satisfy the function.

Therefore, the 1st and 2nd inequality are satisfying the function, Option A is correct.

Jim's percent error is 3.03%.

The percentage error is given as the difference between the actual value and the estimated value divided by the actual value, multiplied by 100%.

The percentage error is a relative value that compares the actual value and the estimated value to explain any deviations.

Estimated width of wall = 8 feet

The actual width of the wall = 8.25 feet

The difference in estimate = 0.25 feet (8.25 - 8)

Percentage Error = 3.03% (0.25/8.25 x 100)

Thus, we can conclude that Jim made a percentage error of 3.03% in his estimate of the width of the wall.

Step-by-step explanation:

Hello, there! Nice to meet you.

This is a pretty easy question, as it's written in y = mx + b form.

When it's written like this, the m in replacement is your slope value.

So, in this case, -6.3 is your slope.

If I had y = 3x + 6, then 3 would be the slope, but that's just an example.

Once more, the m value is your slope.

The slope of the line between the two points defined in the graph is 1/2.

Slope of the line:

The slope of a line is the change in y coordinate with respect to the change in x coordinate.

m = Δy/Δx

Where the net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx. Where “m” is the slope of a line

Given,

There is a graph presented here.

Through the graph we have identified two points,

They are (3,0) and (-3, -3).

Now we need to find the slope of the line between these points.

Here we consider the values of (x1,y1) as (3,0) and the value of (x2,y2) as (-3,-3).

Through the values we have to identify the slope of the line.

For that, we have to apply the values on the formula,

Then we get,

m = (-3 - 0)/(-3-3)

m = -3/-6

m = 1/2

Therefore, the slope of the line is 1/2.
