Answer:
Third one will be correct.
Step-by-step explanation:
Given : y =[tex]log_{8}(x)[/tex].
To find : Graph and its inverse.
Solution : We have given that
y =[tex]log_{8}(x)[/tex].
For x - intercept , y =0.
y = 0
0 =[tex]log_{8}(x)[/tex].
x = 1
(1,0)
Inverse of y =[tex]log_{8}(x)[/tex].
Interchange the x and y.
x = [tex]log_{8}(y)[/tex].
Solving for y
y = [tex]8^{x}[/tex].
Then For x = 0
y = [tex]8^{0}[/tex].
y = 1
For inverse ( 0 ,1)
Then we can see from given graphs Third one will be correct.
Therefore, Third one will be correct.

A rectangular area is to be fenced in with 600 feet of chicken wire. find the maximum area that can be enclosed.
Answers
the area of the area is max when it's a square
the length of the square is 600/4 = 150
so the max area that can be enclosed is:
150×150 = 22500 ft square
The maximum area that can be enclosed is 22500 feet²
A rectangle is a quadrilateral in which opposite sides are equal and parallel to each other.
Let x represent the length and y represent the width. Hence:
perimeter = 2(length + width)
600 = 2(x + y)
300 = x + y
y = 300 - x
The area of a rectangle (A) = length * width
A = x * (300 - x)
A = 300x - x²
The maximum area is at dA/dx = 0, hence:
dA/dx = 300 - 2x
300 - 2x = 0
2x = 300
x = 150 feet
y = 300 - x = 300 - 150 = 150 feet
The maximum area = x * y = 150 * 150 = 22500 feet²
The maximum area that can be enclosed is 22500 feet²

Which function has the range (-infinity,0)u(2,infinity)?
A. y = sex x
B. y = cot (2x) - 1
C. y = cos (x+1)
D. y = csc(x) + 1
Answers
Answer:y=csc(x) -1
Step-by-step explanation:
The correct answer is option D. y = csc(x)+1
To determine which function has the range (-infinity, 0) U (2, infinity), we need to analyze each option:
A. y = sec(x): The range of sec(x) is [tex](-\infty,-1] \cup[1,\infty)[/tex], not matching our target range.B. y = cot(2x) - 1: The range of cot(x) is [tex](-\infty,\infty)[/tex], so cot(2x) also has a range of [tex](-\infty,\infty[/tex]). Shifting it down by 1 unit, the range becomes [tex](-\infty, \infty) - 1 = (-\infty, \infty)[/tex], also not matching.C. y = cos(x + 1): The range of cos(x) is [-1, 1], so cos(x + 1) still has a range of [-1, 1] after translating horizontally, which does not match.D. y = csc(x) + 1: The range of csc(x) is [tex](-\infty,-1]\cup[1,\infty)[/tex]. When we add 1 to it, we get [tex](-\infty,0]\cup[2,\infty)[/tex] - which simplifies to our target range of [tex](-\infty,0]\cup[2,\infty)[/tex].Therefore, the function is y = csc(x) + 1.

Answer the word problem:
Taylor and Blair are driving away from each other in opposite directions. If Blairs speed is 70mph and Taylors speed is 80mph, how many hours will it be before the two are 225 miles apart?
Answers
It will take 1.5 hours (or 1 hour and 30 minutes) before Taylor and Blair are 225 miles apart.
To find out how many hours it will be before Taylor and Blair are 225 miles apart, we can set up an equation based on the distance they travel.
Since they are driving away from each other in opposite directions, their distances add up to the total distance they will be apart.
Let t be the number of hours it takes for them to be 225 miles apart.
Distance traveled by Blair = Blair's speed * time (d = r * t)
Distance traveled by Taylor = Taylor's speed * time (d = r * t)
The total distance they will be apart is 225 miles:
Blair's distance + Taylor's distance = 225 miles
(70 mph * t) + (80 mph * t) = 225 miles
Now, solve for t:
70t + 80t = 225
150t = 225
t = 225 / 150
t = 1.5
So, it will take 1.5 hours (or 1 hour and 30 minutes) before Taylor and Blair are 225 miles apart.

He should visit Tampa Bay. The range is very large, so there is a better chance that any given day will be warm.
Answers
He should visit Orlando. The median is higher and the range is smaller, so the temperature is higher on average. This is the correct answer, as we are only interested in the average temperature in both cities in deciding which to go to. The larger the range (max - min values) or interquartile range (range of central box), the more spread out the temperatures are around the median. As Orlando's range and interquartile range is lower than Tampa Bay's, and its median (middle value in the data set of temperatures) is higher, Dominick would, on average, have more chance of visiting Orlando on a day when it was warmer than Tampa Bay than the other way around.
The correct answer is option b. Dominick should visit Orlando. The median is higher and the range is smaller, so the temperature is higher on average.
Option b is correct because if Orlando has a higher median temperature, this suggests that the middle value of the temperatures in Orlando is higher than in Tampa Bay. Additionally, a smaller range indicates less variability, suggesting more consistent warm temperatures. Therefore, the higher median and smaller range are strong indicators that, on average, the temperatures in Orlando are warmer.
Why other options are incorrect:
Option a is incorrect because the Interquartile Range (IQR) represents the middle 50% of the data. While a greater IQR indicates a larger spread in the middle 50% of the temperatures, it doesn't necessarily mean the average temperature is higher.
Option c is incorrect while Tampa Bay having the highest temperature might indicate that it reached the highest peak temperature, this single data point does not provide enough information about the overall average or consistency of warm temperatures. The highest temperature alone doesn't guarantee that the city is warmer on average.
Option d is incorrect because a larger range indicates a wider spread of temperatures, which could mean more variability. This does not necessarily mean that any given day will be warm; it could also mean that there are very low temperatures included in that range.
The complete question is
Dominick is planning to take a vacation to either Orlando or Tampa Bay. He wants to go to the city that is warmer, on average. The box plot shows the temperatures from the previous year during the time that Dominick will take his vacation:
Which city should Dominick visit, and why?
a. He should visit Orlando. It has a greater IQR.
b. He should visit Orlando. The median is higher and the range is smaller, so the temperature is higher on average.
c. He should visit Tampa Bay. The highest temperature occurred there.
d. He should visit Tampa Bay. The range is very large, so there is a better chance that any given day will be warm.

write an equation thats parellel to the given line & that passes through the given point y=5/2x-10;(6,-29)
Answers
Explanation: Any lines that are parallel to each other share the same slope but have different y-intercepts. To solve for this problem, keep you would first need to find out the b-value or the y-intercept. To do this, set up the y=mx+b equation and plug the slope into m (5/2). Then, since you know the line has to pass through points (6, -29) you would plug those points into the equation: -29=5/2(6) + b . You will then solve for b and your b-value will be -44. Now, since you know your slope and your y-intercept, you now know your answer is y= 5/2x-44.
