characteristics of the functions? Select two options.
Of(x) has an all negative domain.
g(x) has the greatest maximum value.
All three functions share the same range.
Oh(x) has a range of all negative numbers.
All three functions share the same domain.
Answer:
The statements that can be used to compare the characteristics of the functions are:
1. g(x) has the greatest maximum value.
2. All three functions share the same domain.
Explanation:
- The table shows the values of three functions - f(x), g(x), and h(x) - evaluated at different values of x.
- We cannot determine the domain of f(x) or h(x) from the given table but we can see that g(x) has a domain of all real numbers.
- We can see that g(x) has the highest maximum value among the three functions, which is 8.
- We cannot determine the range of f(x) or g(x) from the given table but we can see that h(x) has a range of all negative numbers.
- We cannot say anything about the domain or range of f(x) based on the given table.
- Therefore, the two statements that can be used to compare the characteristics of the functions are: g(x) has the greatest maximum value and all three functions share the same domain.

A wildlife group is trying to determine how many wild hogs are in a certain area. They trapped, tagged, and released 20 wild hogs. Later, they counted 8 wild hogs out of the 40 they saw.
What can the wildlife group estimate is the total population of wild hogs in that area
A. 80
B. 90
C. 100
D. 16
Answer:
The correct answer is 16
Step-by-step explanation:
Answer:
C. 100
Step-by-step explanation:
Assuming that the proportion of tagged hogs in the population is the same as the proportion of tagged hogs in the sample that was later observed, we can set up a proportion to estimate the total population of wild hogs:
tagged hogs in population / total population = tagged hogs in sample / size of sample
We know that 20 wild hogs were tagged and released, and that 8 out of 40 hogs observed were tagged. So we can plug these numbers into the proportion and solve for the total population:
20 / total population = 8 / 40
Simplifying this equation, we get:
total population = (20 * 40) / 8 = 100
Therefore, the wildlife group can estimate that the total population of wild hogs in the area is 100. Answer choice C is correct.

What is Permutation?A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters. Mathematically, number of possible arrangements can be calculated using -
\(\bold{P(n, r) = n! \div (n - r)!}\)
Given is a dog show in which 3 medals are to be awarded to 4 finalists.
Number of medals [n] = 3
Number of finalists [f] = 4
Number of ways for awarding 3 medals to 4 finalists can be calculated using permutation as follows -
\(\bold{P(n, r) = n! \div (n - r)!}\)
\(\text{P}(4, 3) = 4! \div (4 - 3)!\)
\(\text{P}(4, 3) = 4! \div 1!\)
\(\text{P}(4, 3) = (4 \times 3 \times 2 \times 1 )\div(1 \times 1)\)
\(\text{P}(4, 3) = 4 \times 3 \times 2\)
\(\bold{P(4, 3) = 24}\)
Therefore, the total number of possible ways to award 3 medals to 4 finalists are 24.

Find the sum of the all the multiple of 3 beta between 100 and 301 cinclusives which are multiples of 3.
Answer: 13,467
Step-by-step explanation:
The first multiply of 3 after 100 is 102 (102/3 = 34) and the last multiple of three before 301 is 300 (300/3 = 100).
So, we can organize the multiples of 3 in a sequence: (102, 105, ..., 297, 300).
As we can see, we have an arithmetic sequence above, with the following parameters:
first term = a1 = 102
last term = an = 300
number of terms = n = ?
common difference = d = 3
First, we have to find the number of terms of this sequence. To do this, we can use the following formula:
\(\begin{gathered} an=a_1+(n-1)\cdot d \\ 300=102+(n-1)\cdot3 \\ 300-102=(n-1)\cdot3 \\ 198=(n-1)\cdot3 \\ \frac{198}{3}=n-1 \\ 66=n-1 \\ 66+1=n \\ n=67 \end{gathered}\)Now, we can use the formula for the sum (S) of the arithmetic sequence and find the sum of the terms:
\(\begin{gathered} S=\frac{n\cdot(a_1+an)}{2} \\ S=\frac{67\cdot(102+300)}{2} \\ S=13,467 \end{gathered}\)The sum is 13,467.
Randall recorded the total number of comic books in five different school libraries.
Rank the libraries from 1 having the
GREATEST total number of comic books to 5 having the LEAST total number of comic books.
Library A: 30 comic books are 2% of its total books.
Library B: 45 comic books are 5% of its total books.
Library C: 65 comic books are 2% of its total books.
Library D: 75 comic books are 10% of its total books.
Library E: 90 comic books are 3% of its total books.
To rank the libraries from 1 having the greatest total number of comic books to 5 having the least total number of comic books, we need to first calculate the total number of books in each library.
Let's start by using the information given to find the total number of books in each library:
For Library A, we know that 30 comic books are 2% of its total books. So, we can set up the following equation:
30 = 0.02x
where x is the total number of books in Library A. Solving for x, we get:
x = 1500
Therefore, Library A has a total of 1500 books.
For Library B, we know that 45 comic books are 5% of its total books. So, we can set up the following equation:
45 = 0.05x
where x is the total number of books in Library B. Solving for x, we get:
x = 900
Therefore, Library B has a total of 900 books.
For Library C, we know that 65 comic books are 2% of its total books. So, we can set up the following equation:
65 = 0.02x
where x is the total number of books in Library C. Solving for x, we get:
x = 3250
Therefore, Library C has a total of 3250 books.
For Library D, we know that 75 comic books are 10% of its total books. So, we can set up the following equation:
75 = 0.1x
where x is the total number of books in Library D. Solving for x, we get:
x = 750
Therefore, Library D has a total of 750 books.
For Library E, we know that 90 comic books are 3% of its total books. So, we can set up the following equation:
90 = 0.03x
where x is the total number of books in Library E. Solving for x, we get:
x = 3000
Therefore, Library E has a total of 3000 books.
Now that we have the total number of books in each library, we can rank them based on the number of comic books they have:
Library C: 65 comic books
Library E: 90 comic books
Library B: 45 comic books
Library A: 30 comic books
Library D: 75 comic books
Therefore, the libraries ranked from 1 having the greatest total number of comic books to 5 having the least total number of comic books are: C, E, B, A, D.

Describe the transformations of f(x) to get to g(x) pic attached below
The transformation sequence of the function is:
The function is first shifted to the left, then vertically stretched, and finally vertically shifted up and down to get the final graph.
We have,
The transformations of f(x) = 2^x to get to g(x) = -5 + 2^{x + 6} + 3 are as follows:
Translation:
f(x) is translated 6 units to the left, which gives 2^{x+6}.
Vertical stretch/compression:
The entire function is multiplied by 2, which makes it taller.
Vertical shift:
The entire function is shifted up 3 units and down 5 units, which raises the entire graph 3 units and then lowers it 5 units from its original position.
Thus,
The function is first shifted to the left, then vertically stretched, and finally vertically shifted up and down to get the final graph.

Dennis wants to save $189 for a trip to an amusement park. He sets aside $14 of his allowance at the end of each week. How many weeks will it take him to save enough money for the whole trip?
Answer:
x = 13.5 weeks
Step-by-step explanation:
Since he wants to save $189 in total, that will be on one side of the equation by itself. You have to set this up in a y = mx + b equation. The y will be the 189. Since the word "each" goes with the number 14, that will be your m value. There is no value for b.
189 = 14x is your equation. The only step after setting up the equation is to divide 189 by 14. This gives you 13.5. Dennis will have to save up for 13.5 weeks.

Hi there!
it would be 30m+100
Expressions can’t have equal signs or just a number so we can cross out A and B...
m-30m means money-30 times money which doesn’t make sense.
30m+100 would be 30m+100 which is correct since the total would be 130$ and if m is 1, then this expression is correct,

A car is driving away from El Paso with constant velocity. At 1 p.m., it is 145 miles away from El Paso. At 3 p.m., it is 275 miles away from El Paso.
Part A: Write a linear function that describes the distance (in miles) the car is from El Paso in terms of time (in hours after 12:00 p.m.).
The linear function that describes the distance (in miles) is therefore y = 65x + 80
How to solve for the linear functionWe have to find the slope and the intercept in other to get the linear function
The data points are:
(1, 145) and (3, 275).
m = (y2 - y1) / (x2 - x1)
fixing the data points we have
m = (275 - 145) / (3 - 1)
= 130 / 2
= 65
y = mx + b
(1, 145):
145 = 65(1) + b
b = 145 - 65
= 80
y intercept is 80

First, we need to cross multiply on both sides, which gives us:
9 * (5x - 6) = 27 * (2 + x)
45x - 54 = 54 + 27x
Now, we want to isolate x on either side.
We can substract 54 from both sides:
(45x - 54 = 54 + 27x) - 54
45x - 108 = 27x
We then subtract 45 from both sides:
(45x - 108 = 27x) - 45
-108 = -18x
Finally, we divide both sides by -18:
(-108 = -18x) / -18

Answer:
Let's assume the original price of the stock was x.
When the company announced it overestimated demand, the stock price fell by 40%.
So, the new price of the stock after the first decline was:
x - 0.4x = 0.6x
A few weeks later, when the seats were recalled, the stock price fell again by 60% from the new lower price of 0.6x.
So, the new price of the stock after the second decline was:
0.6x - 0.6(0.6x) = 0.24x
Given that the current stock price is $2.40, we can set up the equation:
0.24x = 2.40
Solving for x, we get:
x = 10
Therefore, the stock was originally selling for $10.
