By using the squeeze theorem, we conclude that, [tex]$$\lim _{x \rightarrow a} f(x)=b .$$[/tex]

Limit of a function, Squeeze Law:

The squeeze theorem 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. We can use the theorem to find tricky limits like sin(x)/x at x=0, by "squeezing" sin(x)/x between two nicer functions and ​using them to find the limit at x=0

We say that a function f(x) approaches a limit L approaches a, or, [tex]$\lim _{x \rightarrow a} f(x)=L$[/tex]

if, for every number [tex]$\epsilon > 0$[/tex], however small, such that [tex]$|f(x)-L| < \epsilon$[/tex],

there always exists a number δ>0 such that

[tex]|x-a| < \delta \text {. }[/tex]

The Squeeze Law:

Suppose that g(x) ≤ f(x) ≤h(x) in some neighborhood of a and also that

[tex]$$\lim _{x \rightarrow a} g(x)=L=\lim _{x \rightarrow a} h(x)$,[/tex]

then,

[tex]$$\lim _{x \rightarrow a} f(x)=L .$$[/tex]

We have to find the limit of f(x) as x approaches to x.

Let [tex]$b-|x-a|=g(x)$[/tex] and [tex]$b+|x-a|=h(x)$[/tex].

Then we have the inequality, g(x) ≤ f(x) ≤h(x)

Let us see what happens to g(x) and h(x) as [tex]$$x \rightarrow a$.[/tex]

[tex]$$\begin{aligned}g(x) & =b-|x-a| \\\\lim _{x \rightarrow a} g(x) & =\lim _{x \rightarrow a} b-|x-a| . \\& =b\end{aligned}$$[/tex]

Similarly,

[tex]$$\begin{aligned}h(x) & =b+|x-a| \\\lim _{x \rightarrow a} h(x) & =\lim _{x \rightarrow a} b+|x-a| . \\& =b\end{aligned}$$[/tex]

We have the conditions required by the Squeeze law,

[tex]$$\lim _{x \rightarrow a} g(x)=b=\lim _{x \rightarrow a} h(x)$$[/tex]

so we conclude that, [tex]$$\lim _{x \rightarrow a} f(x)=b .$$[/tex]

Answer:

A

Step-by-step explanation:

Answer:

40.2°

Step-by-step explanation:

formula: y = mx + b

current points we know:

m = 1/2

x = 10

y = 0

so we solve for the b value.

0 = 1/2 (10) + b

0 = 5 + b

(inverse operation we subtracted 5 on both sides)

-5 = b

so the equation for a line with slope 1/2 passing through the point (10,0) is

y = (1/2)x + (-5) or y = (1/2)x - 5

The total cost of the skateboard if Loui has to pay a state sale tax of 6. 25% is 72.26.

As per the given data, Loui wants to buy a skateboard that has an original price of 79.91, will be discounted 12 %, and will have a sales tax of 6.25 %.

When performing the calculations, remember to convert percent to decimal form and if needed, round to two decimal places since money must be rounded to the nearest cent.

First, we need to find the amount of the discount and then find the sale price (the price after the discount):

Sale price:

Original price - Amount of discount = 79.91 - 11.9 = 68.01

Now that we have the sale price, we can find the amount of tax and then the total cost:

Amount of tax  = ( sale price) × (sales tax percent)

[tex]$$\begin{aligned}& =\ 68.01 \times \ 0.0625 \\& \approx \ 4.25 \end{aligned}$$[/tex]

Total cost = sale price + amount of tax

= 68.01 +  4.75

= 72.26

Comparing both given functions, we can state that: B. Function 1 has the greater rate of change; the slope is 2.

Another name for the rate of change of a function is the slope. It is calculated using the formula:

Slope / rate of change = change in y / change in x.

If the equation of a linear function is given in slope-intercept form as y = mx + b, the rate of change or the slope is represented by "m".

Given the first function as an equation, y = 2x - 6, the slope of this function is represented as 2. This means, the rate of change is m = 2.

To find the rate of change of function 2, use two points from the table, (1, -4) and (2, -5):

Rate of change / slope (m) = (-5 - (-4)) / (2 - 1) = -1/1

m = -1.

The slope value of 2 is greater than the slope value of -1, therefore, we can conclude that: B. Function 1 has the greater rate of change; the slope is 2.

Based on the correlation coefficient from the technology data given, the data has a strong negative association.

The correlation coefficient is defined as a statistical measure of the strength of a linear relationship that exists between two variables.

The possible range of values for correlation coefficient is from -1.0 to 1.0. This tells us that the values cannot be more than 1.0 nor be less than -1.0.

Thus, a correlation coefficient of -1.0 shows a perfect negative correlation, while a correlation coefficient of 1.0 shows a perfect positive correlation.

We are given a correlation coefficient of r = -0.9478.

Now, the closer the negative correlation is to -1 indicates a strong negative correlation while the farther it is from -1 indicates a weak negative correlation.

Thus, we can conclude that in this case where the  negative correlation is closer to -1 than farther, it can be said to be a strong negative correlation.

Answer: The two expressions that represent the perimeter of the rectangular pool include the following:

A. x + 3x + 1 + x + 3x + 1

E. 8x + 2

How to calculate the perimeter of a rectangle?

Mathematically, the perimeter of a rectangle can be calculated by using this equation;

P = 2(L + x)

Where:

P represents the perimeter of a rectangle.

L represents the length of a rectangle.

x represents the width of a rectangle.

Since the length is 1 more than 3 times the​ width, we have;

Length, L = 3x + 1

Therefore, the two expressions for the perimeter of this rectangle is given by:

P = 2(3x + 1 + x) = x + 3x + 1 + x + 3x + 1

P = 2(4x + 1) = 8x + 2

Next, we would determine the total cost as follows;

P = 8x + 2

P = 8(20) + 2

P = 162 feet.

Total cost = 1.86 × 162

Total cost = $301.32

Step-by-step explanation:

To determine the total price of the phone including taxes, we need to first calculate the amount of sales tax by multiplying the price of the phone by the sales tax rate:

Sales tax = Price of phone * Sales tax rate

Sales tax = $39 * 5%

Sales tax = $1.95

Next, we can calculate the total price of the phone including taxes by adding the amount of sales tax to the price of the phone:

Total price including taxes = Price of phone + Sales tax

Total price including taxes = $39 + $1.95

Total price including taxes = $40.95

Rounded to the nearest cent, the total price of the phone including taxes is $41.00.

The train does not always go the same distance each minute.

Predicted amount of time to travel 30 kilometers is equal to 47.52 minutes.

In order to determine a linear equation for the line of best fit (trend line) that models the data points contained in the table, we would have to use a graphing calculator (scatter plot).

In this scenario, the time (in minutes) would be plotted on the x-axis of the scatter plot while the distance (km) would be plotted on the y-axis of the scatter plot.

On the Excel worksheet, you should right click on any data point on the scatter plot, select format trend line, and then tick the box to display an equation for the line of best fit (trend line) on the scatter plot.

From the scatter plot (see attachment) which models the relationship between the distance (km) and time (in minutes), a linear equation for the line of best fit is given by:

y = 1.40x + 5.52

Next, we would determine the predicted amount of time to travel 30 kilometers:

Option (d) is correct. Heteroscedasticity of residuals in regression suggests that there is a non constant variation in the error.

Heteroscedasticity means unequal scatter. In regression analysis, we talk about heteroscedasticity in the context of the residuals or error term. Heteroscedasticity is a systematic change in the spread of the residuals over the range of measured values. Heteroscedasticity is a problem because ordinary least squares regression assumes that all residuals are drawn from a population that has a constant variance that is heteroscedasticity. the residuals should have a constant variance. Heteroscedasticity is also called as heteroskedasticity. It occurs more often in datasets that have a large range between the largest and smallest observed values. This explains Heteroscedasticity.
