Find the limit
(calculus)
Answer:
I believe [tex]\lim_{x \to a} f(x)[/tex] also equals 0.
Step-by-step explanation:
We know that g(x) has to be greater than or equal to 0. That means f(x) has to be smaller than g(x) or equal to 0.
If we plug in any value of x, f(x) will be positive because of the absolute value. The only way we are going to get f(x) smaller than g(x) or equal to g(x) is to have very small fractions.
Therefore, if [tex]\lim_{x \to a} g(x)=0[/tex], then [tex]\lim_{x \to a} f(x)=0[/tex] because f(x) must be smaller or equal to 0 as well.
Answer:
[tex]\displaystyle{ \lim_{x\to a}f(x)=0[/tex]
Step-by-step explanation:
The other user posted a great answer, but I would like to show you a more mathematical way!
We have [tex]|f(x)|\leq g(x)[/tex].
By the definition of absolute value, this is the same as saying:
[tex]f(x)\leq g(x)\text{ and } -f(x)\leq g(x)[/tex]
For the right, we can divide both sides by -1 to acquire:
[tex]f(x)\leq g(x)\text{ and } f(x)\geq- g(x)[/tex]
We can now combine them. This yields:
[tex]-g(x)\leq f(x)\leq g(x)[/tex]
Now, we can use the Squeeze Theorem (a.k.a. Pinch or Sandwich Theorem). The Squeeze Theorem posits that if we have:
[tex]g(x)\leq f(x)\leq h(x)[/tex]
And:
[tex]\displaystyle{ \lim_{x \to c} g(x)= \lim_{x \to c} h(x)=L}[/tex]
Then the following must be true:
[tex]\displaystyle{ \lim_{x \to c} f(x)=L[/tex]
We have:
[tex]-g(x)\leq f(x)\leq g(x)[/tex]
And we know that:
[tex]\displaystyle{ \lim_{x \to a} g(x)=0[/tex]
Then it follows that:
[tex]\displaystyle{ \lim_{x \to a} -g(x)=- \lim_{x \to a} g(x)=0[/tex]
Therefore, by using the Squeeze Theorem, we can conclude that:
[tex]\displaystyle{ \lim_{x\to a}f(x)=0[/tex]
And we're done!

Graph the solution of the inequality 2x - (3 – x) > x + 1 on the number line.
Answer:
do multiply
Step-by-step explanation:
and take line in right side
The solution of the inequality 2x - (3 – x) > x + 1 is the values greater than 2. Therefore, option D is the correct answer.
The given inequality is 2x - (3 – x) > x + 1.
What is the solution of the inequality?A solution for an inequality in x is a number such that when we substitute that number for x we have a true statement.
Now, 2x - (3 – x) > x + 1 can be solved as follows:
2x -3+x>x+1 (Simplify the bracket)
⇒3x-3>x+1
Subtract x on both the sides of the inequality.
That is, 3x-3-x>x+1-x
⇒2x-3>1
Add 3 on both the sides of the inequality.
That is, 2x>4
Divide 2 on both the sides of the inequality.
That is, 2x÷2>4÷2
⇒ x > 2
The solution of the inequality 2x - (3 – x) > x + 1 is the values greater than 2. Therefore, option D is the correct answer.

What is exponential growth or decay function?Consider the function:
[tex]y = a(1\pm r)^m[/tex]
where m is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.
If there is plus sign, then there is exponential growth happening by r fraction or 100r %
If there is negative sign, then there is exponential decay happening by r fraction or 100r %
We are given that;
f(x)=ab^x
Now,
An exponential growth function is a function that increases as x increases. For the function f(x) = ab^x, this means that the base b must be greater than 1, so that the exponent x makes the function larger.
Therefore, by the exponential growth and decay the answer will be square root of 2 and 1.1

Divide the number 90 into three parts in the ratio 1:4:5.
Answer:
9, 36, and 45
Step-by-step explanation:
The order is 9, 36, and 45 because as we have to divide 90 into 1:4:5, 1+4+5=10 total parts. Then 90 divided by 10 equals to 9. The first number has 1 part, so 9x1=9 for the first number. For 4 parts, 9x4=36 for the second number. For 5 parts, 9x5=45 for the third number. The order is 9, 36, and 45. Hope it helps!
When we divide 90 in 1:4:5 ratio so it comes 9,36, and 45.
Given that,
The number is 90. We have to divide the above number in 1:4:5 ratio.
Based on the above information, the calculation is as follows:
x + 4x + 5x = 90
10x = 90
x = 9
Now multiply each ratio with 9 to get each value.
So, the values should be 9,36, and 45.
Therefore we can conclude that when we divide 90 in 1:4:5 ratio so it comes 9,36, and 45.

What is the Y intercept of the line graphed on the grid
Answer:
5.5
Step-by-step explanation:
The y-intercept of the line graph shown above is the value of the point where the line cuts the y-axis. The y-intercept of this graph is between 5 and 6. However, we can get an accurate value by calculation. This can be done by generating an equation of the line.
Recall the slope-intercept equation, [tex] y = mx + b [/tex], where m = slope of the line, b = y-intercept.
To generate the equation of the line, first find slope using the points (-2, 7) and (6, 1):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 7}{6 -(-2)} = \frac{-6}{8} = -\frac{3}{4} [/tex].
Substitute m = ¾ and the coordinates (6, 1) into the slope-intercept equation to find the y-intercept (b):
[tex] y = mx + b [/tex]
[tex] 1 = -\frac{3}{4}(6) + b [/tex]
[tex] 1 = -\frac{18}{4} + b [/tex]
[tex] 1 = -4.5 + b + 4.5 [/tex]
[tex] 1 + 4.5 = -4.5 + b + 4.5 [/tex]
[tex] 5.5 = b [/tex]
Therefore, b = y-intercept = 5.5.
To generate the equation of the line, plug in the values of m and b, we would have:
y = ¾x + 5.5
The y-intercept of the line of the graph is 5.5.

Alexa is the popular virtual assistant developed by Amazon. Alexa interacts with users using artificial intelligence and voice recognition. It can be used to perform daily tasks such as making to-do lists, reporting the news and weather, and interacting with other smart devices in the home. In , the Amazon Alexa app was downloaded some 2800 times per day from the Google Play store (AppBrain website). Assume that the number of downloads per day of the Amazon Alexa app is normally distributed with a mean of 2800 and standard deviation of 860. What is the probability there are 2000 or fewer downloads of Amazon Alexa in a day (to 4 decimals)? What is the probability there are between 1500 and 2500 downloads of Amazon Alexa in a day (to 4 decimals)? What is the probability there are more than 3000 downloads of Amazon Alexa in a day (to 4 decimals)? Assume that Google has designed its servers so there is probability 0.01 that the number of Amazon Alexa app downloads in a day exceeds the servers' capacity and more servers have to be brought online. How many Amazon Alexa app downloads per day are Google's servers designed to handle (to the nearest whole number)?
Step-by-step explanation:
What is the probability there are 2000 or fewer downloads of Amazon Alexa in a day (to 4 decimals)?
First, find the z-score.
z = (x − μ) / σ
z = (2000 − 2800) / 860
z = -0.930
Use a chart or calculator to find the probability.
P(Z < -0.930) = 0.1761
What is the probability there are between 1500 and 2500 downloads of Amazon Alexa in a day (to 4 decimals)?
Find both z-scores.
z = (x − μ) / σ
z₁ = (1500 − 2800) / 860
z₁ = -1.512
z₂ = (2500 − 2800) / 860
z₂ = -0.349
Use a chart or calculator to find the probability.
P(-1.512 < Z < -0.349) = P(Z < -0.349) − P(Z < -1.512)
P(-1.512 < Z < -0.349) = 0.3636 − 0.0653
P(-1.512 < Z < -0.349) = 0.2983
What is the probability there are more than 3000 downloads of Amazon Alexa in a day (to 4 decimals)?
Find the z-score.
z = (x − μ) / σ
z = (3000 − 2800) / 860
z = 0.233
Use a chart or calculator to find the probability.
P(Z > 0.233) = 1 − P(Z < 0.233)
P(Z > 0.233) = 1 − 0.5919
P(Z > 0.233) = 0.4081
Assume that Google has designed its servers so there is probability 0.01 that the number of Amazon Alexa app downloads in a day exceeds the servers' capacity and more servers have to be brought online. How many Amazon Alexa app downloads per day are Google's servers designed to handle (to the nearest whole number)?
Use a chart or calculator to find the z-score given the probability.
P(Z > z) = 0.01
P(Z < z) = 0.99
z = 2.3263
Now find the corresponding number for that z-score.
z = (x − μ) / σ
2.3263 = (x − 2800) / 860
x = 4801
Using the binomial probability principle, the probability values for the number of downloads are :
P(X ≤ 2000) = 0.1762 P(1500 ≤ X ≤ 2500) = 0.2981P(X > 3000) = 0.4081Maximum number of downloads = 4800Given the Parameters :
Mean, μ = 2800Standard deviation, σ = 860The Zscore formula ::
Zscore = (X - μ) / σ1.) Probability of 2000 or fewer downloads :
P(X ≤ 2000) = P(Z ≤ (2000 - 2800)/860)) = -0.930
Using a normal distribution table :
P(Z ≤ - 0.930) = 0.1762
2.) Probability of between 1500 and 2000 downloads :
P(1500 ≤ X ≤ 2500) = P(Z ≤ (2500 - 2800)/860) - P(Z ≤ (1500 - 2800)/860)
P(1500 ≤ X ≤ 2500) = P(Z ≤ - 0.349) - P(Z ≤ - 1.511)
P(1500 ≤ X ≤ 2500) = 0.3635 - 0.0654
P(1500 ≤ X ≤ 2500) = 0.2981
3.) Probability of more than 3000 downloads :
P(X > 3000) = P(Z > (3000 - 2800) / 860)) = 0.2325
P(Z > 0.2325) = 1 - P(Z < 0.2325)
Using a normal distribution table :
P(Z > 0.2325) = 1 - 0.5919 = 0.4081
4.) Number of downloads given a probability of 0.01
P(X > 0.01) ;
Using a normal distribution table :
The Z score corresponding to P(Z > 0.01) is 2.326
Using the Zscore formula to calculate the number of downloads, X ;
Zscore = (X - μ) / σ
2.326 = (X - 2800) / 860
2.326 × 860 = X - 2800
2000.36 = X - 2800
X = 2000.36 + 2800
X = 4800.36
Therefore, maximum daily download system is designed to handle 4800.
