The first function is an odd and the second one is neither even nor odd. The correct options are (1) and (2).
What is a function?A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
The given problem can be solved as follows,
(2) The graph of the given function shows the following,
The value of the function is positive for positive x and negative for negative x.
It can be mathematically written as,
f(-x) = -f(x).
Which shows the given graph is of an odd function.
(3) The given function is f(x) = 4x³ + 2x² - x⁵.
In order to check the type of the function, find its value at the same value of x with different signs as,
f(1) = 4 × 1³ + 2 × 1² - 1⁵ = 5
And, f(-1) = 4 × -1³ + 2 × -1² - -1⁵ = -1
Since, f(1) ≠ f(-1), the function is not even.
And f(-1) ≠ -f(1), the function is not odd.
Thus, the given function is neither even nor odd.
Hence, the first and the second functions of the given problem are odd and neither even nor odd respectively.

The equation for line s can be written as y+9=–9(x–8). Perpendicular to line s is line t, which passes through the point (9,9). What is the equation of line t?
Write the equation in slope-intercept form. Write the numbers in the equation as simplified proper fractions, improper fractions, or integers.
Answer:
Line t: y = 1/9x + 8
Step-by-step explanation:
The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
The formula for finding the slope the line perpendicular to line s is:
[tex]m_{2}=-\frac{1}{m_{1} }[/tex], where m2 is the slope of the line we don't know (in this case, line t) and m1 is the slope of the line we're given (in this case, line s).
Currently line s is in point-slope form or
[tex](y-y_{1})=m(x-x_{1})[/tex]. Since m is the slope, we know that the slope of line s is -9.
By plugging in -9 for m1 in our equation, we have:
[tex]m_{2}=-\frac{1}{-9}\\ m_{2}=-\frac{1}{9}[/tex]
Since we know -1/9 is the slope of line t, we can plug this in for m and (9,9) for x and y in the slope-intercept equation to find b:
[tex]9=1/9(9)+b\\9=1+b\\8=b[/tex]
Thus, the equation of line t in slope intercept form is y = 1/9x + 8

4. C
Step-by-step explanation:
2. In a function, the x value cannot have two y values (for example: if the points are (1,2) and (1,3) then that is not a function).
In this question, none of the x values repeat with multiple y values, so it is a function. the answer is C.
It is not D, because not all straight lines are functions. If the straight line is vertical, then there is only one x value and it has infinitely many values for y. So, not all straight lines are necessarily functions.
3. Range is the y values. The points are (3,4), (-2,3), (7,1), (2, 1/2)
Here, the y values are 4, 3, 1, and 1/2
Choices B,C,E,F are the answers.

Two basketball players are trying to have the most
points per game for the season. The current leader has
2112 points in 77 games and the second place player
has 2020 in 74 games. Assuming the current leader
plays no more games, how many points per game will
the second place player have to score in each of the
next three games to take the lead in this category?
The second place player must earn 0.0467 points per game in each of the next three games to take the lead in this category.
What is PPG Statistics?
The average amount of points scored by a player per game played in a sport, over the length of a run of games, a season, or a career, is known as points per game, or PPG. It is computed by dividing the total points by the number of games. Basketball and ice hockey are two sports where the jargon is frequently utilized.The points per game is an important statistic and it can range between 0 to 40+.First, calculate the PPG earned by the current leader of the season.
The total points earned by the current leader amount to 2112 and he had participated in a total of 77 games.
The following formula can be used to determine the PPG earned by the current leader per game,
PPG = Total Points / Total Games
[tex]\implies PPG=\frac{2112}{77}\\ \implies PPG = 27.42[/tex] -----(1)
Now, calculate the PPG of the player who is ranked in the second place for the season.
The total number of points earned by the second place player is 2020 and he played a total of 74 games.
The second place player earned the following points per game,
PPG = Total Points / Total Games
[tex]\implies PPG=\frac{2020}{74}\\ \implies PPG = 27.29[/tex] ---(2)
The difference in score with the leading team can be found by subtracting (2) from (1),
[tex]\implies 27.42-27.29=0.13[/tex]
So, to be the leading player, the second place player must obtain a lead of 0.14 points per game in the next three games if the current player plays no more games.
In such a situation, the total PPG of the player should be 27.43 and the number of games to be played is 3.
So, the number of points required to take lead can be calculated as,
PPG = Total Points / Total Games
[tex]\implies 27.43=P/3[/tex]
So, the Total Points required, [tex]P=27.43 \times 3 =82.29[/tex]
And, the PPG required by the second place player to score in each of the next three games is calculated as,
[tex]\frac{0.14}{3}=0.0467[/tex]
Therefore, the second place player must earn 0.0467 points per game in each of the next three games to take the lead in this category.

In a raffle, one ticket will win a $560 prize, one ticket will win a $490 prize, one ticket will win a $270 prize, one ticket will win a $180 prize, and the remaining tickets will win nothing. There are 500 in the raffle. If you have a ticket, what is the expected payoff?
The expected payoff from the raffle is given as follows:
$3.
How to obtain the expected payoff?The payoff is modeled by a discrete distribution, hence the expected payoff is the expected value of the said discrete distribution.
There are 500 tickets in the raffle, hence the probabilities are given as follows:
P(X = 560) = 1/500.P(X = 490) = 1/500.P(X = 270) = 1/500.P(X = 180) = 1/500.P(X = 0) = 496/500.The expected value of a discrete distribution is calculated as the sum of all outcomes multiplied by it's respective probability, hence:
E(X) = 560 x 1/500 + 490 x 1/500 + 270 x 1/500 + 180 x 1/500 + 0 x 496/500 = $3.

1 meter and 59 centimeters.
Describe the hypotenuse.The longest side in a right triangle is called the hypotenuse. In other terms, the hypotenuse is the side that faces the right angle.
theorem of Pythagoras
[tex]a^{2} +b^{2} = c^{2}[/tex]
A is a right triangle's side.
B is the right triangle's side.
c = hypotenuse
Think of a right triangle where the height and distance are the legs and the hypotenuse is the rope.
We are aware that:
cos(45°) =x/10
cos(30°) =y/10,
where x represents the distance between the ship and the dock at low tides and y represents the distance during high tides.
We are searching for the y-x distance difference (since it will be farther away during high tides).
Using the previous equations:
x=cos(45°) and y=cos(30°)
Hence:
y - x = 10(cos(30°) - cos(45°))
Hence, the exact value of the distance is 10(cos30° - cos45°)
Using a calculator, this is approximately 1.59 meters.
