Using the asymptote concept, the function with a vertical asymptote at x = 3 and an horizontal asymptote at [tex]y = -\frac{1}{2}[/tex] is given by:
[tex]f(x) = -\frac{x}{2(x - 3)}[/tex]
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.The vertical asymptote at x = 3 means that x = 3 is a root of the denominator, hence:
[tex]f(x) = \frac{g(x)}{x - 3}[/tex]
The horizontal asymptote at y = -1/2 means that:
[tex]\lim_{x \rightarrow \infty} f(x) = -\frac{1}{2}[/tex]
Which happens if [tex]g(x) = -\frac{x}{2}[/tex], hence the function is:
[tex]f(x) = -\frac{x}{2(x - 3)}[/tex]

The value of f⁻¹(f⁻¹(7)) is 10
How to determine the value of the expression?The expression is given as:
f⁻¹(f⁻¹(7))
We start by solving the inner expression f⁻¹(7).
The above means that we determine the x value when y = 7.
So, we have:
f⁻¹(7) = 14
Substitute f⁻¹(7) = 14 in f⁻¹(f⁻¹(7))
f⁻¹(14)
Next, we determine the x value when y = 14
f⁻¹(14) = 10
Hence, the value of f⁻¹(f⁻¹(7)) is 10

A ski resort claims that there is a 75% chance of snow on any given day in january and that snowfall happens independently from one day to the next. a family plans a four-day trip to this ski resort in january. let x represent the number of days it snows while the family is there. what are the mean and standard deviation of x? mu subscript x baseline = 1, sigma subscript x baseline = 1 mu subscript x baseline = 2, sigma subscript x baseline = 0.56 mu subscript x baseline = 3, sigma subscript x baseline = 0.75 mu subscript x baseline = 3, sigma subscript x baseline = 0.87
Using the binomial distribution, it is found that the mean and the standard deviation of variable x are given as follows:

If f(x)=2(3x-5) when f(x) =74,what is the value of x??
Answer:
x = 14
Step-by-step explanation:
given f(x) = 2(3x - 5) and f(x) = 74 , then equating gives
2(3x - 5) = 74 ( divide both sides by 2 )
3x - 5 = 37 ( add 5 to both sides )
3x = 42 ( divide both sides by 3 )
x = 14

[tex]\cos{\theta} = \pm \frac{2\sqrt{2}}{3}[/tex][tex]\tan{\theta} = \pm \frac{\sqrt{2}}{4}[/tex]What is the trigonometric identity using in this problem?The identity that relates the sine squared and the cosine squared of the angle, as follows:
[tex]\sin^{2}{\theta} + \cos^{2}{\theta} = 1[/tex]
In this problem, we have that the sine is given by:
[tex]\sin{\theta} = \frac{1}{3}[/tex]
Hence, applying the identity, the cosine is given as follows:
[tex]\cos^2{\theta} = 1 - \sin^2{\theta}[/tex]
[tex]\cos^2{\theta} = 1 - \left(\frac{1}{3}\right)^2[/tex]
[tex]\cos^2{\theta} = 1 - \frac{1}{9}[/tex]

[tex]\cos{\theta} = \pm \sqrt{\frac{8}{9}}[/tex]
[tex]\cos{\theta} = \pm \frac{2\sqrt{2}}{3}[/tex]
The tangent is given by the sine divided by the cosine, hence:

⇒ x = 16
Part C⇒ x + 8 = 3x
⇒ 3x - x = 8
⇒ 2x = 8
⇒ x = 4
Part D⇒ x = (x + 5)/2
⇒ 2x = x + 5

Astrid travels 130 km in 2 hours and then at 85 km/h for another 3 hours to reach her
destination. On the return journey home, she travels a total of 5 hours.
Determine the speed of the car that Astrid will travel to get home.
Answer:
[tex]\huge\boxed{\sf Speed = 77\ km/hr}[/tex]
Step-by-step explanation:
Formula to be used in the question:Speed = Distance / TimeDistance for the first 2 hours:= 130 km
Distance for the next 3 hours:Speed = 85 km/h
Time = 3 hours
So,
Distance = Speed × Time
Distance = 85 × 3
Distance = 255 km
So,
Total distance from home to destination:= 130 + 255
= 385 km
Speed on the return journey:Total distance = 385 km
Time = 5 hours
Speed = Distance / Time
Speed = 385 / 5
Speed = 77 km/hr

4. At which point does the function y = -x² + 6x - 5 reach its maximum value?
Answer:
(3,4)
Step-by-step explanation:
Hello!
To find the maximum value, we can find the vertex of the graph.
Since the coefficient of x² is negative, the graph opens downwards, meaning that the vertex would be the highest point.
To solve for the vertex, we can convert it to vertex form.
Converty = -x² + 6x - 5y = -1(x² - 6x) - 5y = -1(x² - 6x + 9) - 5 + 9y = -1(x - 3)² + 4The vertex is (3,4)

What are independent and dependent variables?Even though everything can be almost always related to its reason, when we talk about two related things, there might happen that one of those things is dependent on other.
If a variable is taking its values independently of any visible direct cause, then that variable is called independent variable.The variables who take their values based on some other variables' values are called dependent variables.The complete question is:
A telephone company charges a $0.25 connection fee, then $0.10 per minute for long distance calls. Which statement is true regarding this situation?
A. The rate of change is $0.25 and minutes are the independent variable.
B. The rate of change is $0.25 and minutes are the dependent variable.
C. The rate of change is $0.10 per minute and minutes are the independent variable
D. The rate of change is $0.10 per minute and minute are the dependent variable.
The cost of making a call is the sum of the cost of connection fee which is one time fee and cost $0.25, and the cost charged for a minute which depends on the number of minute for which the call is been established. Therefore, the total cost can be written for a x minute call is,
Total Cost = $0.25 + $0.10(x)
Since the total cost is dependent on x, therefore, x which is the minute is the independent variable. The rate of change is $0.10 per minute and minutes are the independent variable.

It will take them exactly 4hours 48 minutes.
what is rate?Rate is a measure of a given quantity against a known or standard quantity.
Analysis:
If Tanya and Tim cleaned the house in 3 hours. Then either of them would clean the house in 2 x 3 = 6 hours.
If their 3 children cleaned the house in 6 hours, then each child would clean the house in = 3 x 6 = 18 hours
Total time for cleaning the house = 18 hours + 6 hours = 24 hours
If the five people were to do it at once then time taken to clean the house = 24/5 = 4.8 hours = 4 hours 48 minutes
