The answer is
f(x) = (x - 1) 2(x +1)(x - 3 ).
Given equation
f(x) = (x − 2)2(x + 1)(x − 3)
f(x) = (x + 2)2(x − 1)(x + 3)
f(x) = (x + 2)2(x + 1)(x + 3)
f(x) = (x − 2)2(x − 1)(x − 3)

Two sailboats are sailing up a river. The relationship between the distance (d ), in miles, from the starting point to the time (t ), in hours, it takes to sail a distance d for each boat is given.
The correct statement regarding the proportional relationships is given as follows:
Boat A travels at a faster rate than Boat B.
What is a proportional relationship?A proportional relationship is a special case of a linear function with intercept zero in which the output variable is given by the multiplication of the input variable and the constant of proportionality, in the case of a direct relationship, as follows:
y = kx
The function for boat A is:
d = 10.5t.
Hence the rate is:
10.5 miles per hour.
From the graph, the rate for boat B is obtained as follows:
k = 90/10 = 9 miles per hour.
A higher constant means a faster rate, 10.5 is greater than 9, hence boat A travels faster.

Y intercept = -1 and goes through the point (3,8)
The equation of a line for y-intercept and the coordinate point is y=3x-1.
Given that, y-intercept is -1 and the line passes through the point (3, 8).
What is a y-intercept?In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.
Put, c=-1 and (x, y)=(3, 8) in y = mx+c, we get
8=m(3)-1
⇒ 3m=9
⇒ m=3
Substitute c=-1 and m=3 in y = mx+c, we get
y=3x-1
Therefore, the equation of a line for y-intercept and the coordinate point is y=3x-1.

Which system of equations is represented by the graph ?
A. y=x^2+2x+1
2x+y=2
B. y=x^2-2x+1
2x+y=2
C. y=x^2+2x+1
2x+y=2
D. y=x^2-2x+1
2x-y=2
y = x²-2x+1, 2x-y=2 is the system of equations represented by the graph
How to determine the system of equations represented by the graph?
By examining the graph, you will notice that the straight and the curve meet at (3,4) and (1,0) as indicated. The x values of these points of intersection give the solution of the system. Thus:
We have x = 3 and x = 1
These values can be used to form the equation of the system. Thus:
(x-3)(x-1) = 0 (Clear the parenthesis)
x² -x-3x +3 = 0
x² -4x +3 = 0
Next, we are going to check for the option that gives the x² -4x +3 = 0
Given: y = x²-2x+1, 2x-y=2
Rewrite 2x-y=2 to be in form y: y =2x-2
We now have y = x²-2x+1 and y =2x-2
Equate the two y: x²-2x+1 =2x-2
x²-2x+1 -2x+2 = 0
x²- 4x+ 3 = 0
Since y = x²-2x+1, 2x-y=2 gives the same equation, therefore, the system of equations represented by the graph is y = x²-2x+1, 2x-y=2. So option D is the answer

An 80 kg jumper in flight accelerates at a rate of 8 m/s^2. What is the force of the long jumper? F = ma
By taking the product between the mass and the acceleration, we will see that the force is:
F = 640 N
What is the force of the long jumper?
By the second Newton's law, we know that a force can cause motion on a body by accelerating it, such that the force is equal to the product between the mass of the object and the acceleration.
F = m*a
F = forcem = massa = acceleration.Here we know that:
m = 80kg
a = 8 m/s^2

in a tournament there are six teams that play each other twice. a team earns 3 points for a win, 1 point for a draw, and zero points for a loss. after all the games have been played it turns out that the top three teams earned the same number of total points. what is the greatest possible number of total points for each of the top three teams?
The greatest possible number of total points for each of the top three teams is 24.
Given;
Six teams compete against one another twice in a tournament. A team receives three points for a victory, one point for a tie, and no points for a defeat. The top three clubs ended up with the same total number of points when all the games were completed.
After fully understanding the problem, we immediately know that the three top teams, say team A, team B, and team C, must beat the other three teams D, E, F. Therefore, A, B, and C must each obtain (3 + 3 + 3 ) = 9 points. However, they play against each team twice, for a total of 18 points against D, E, and F. For games between A, B, and C, we have 2 cases. There is an equality of points between A, B, and C in the following cases.
Case (I): A team ties the two other teams. For a tie, we have 1 point, so we have (1 + 1) * 2 = 4 points (they play twice).
Therefore, this case brings a total of 4 + 18 = 22 points.
Case (II): A team beats one team while losing to another. This gives equality, as each team wins once and loses once as well. For a win, we have 3 points, so a team gets 3 * 2 = 6 points if they each win a game and lose a game.
This case brings a total of 18 + 6 = 24 points.
Therefore, we use case (II) since it brings the greater amount of points as 24.

What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
The sum of a finite geometric sequence with n terms is given as follows:
[tex]S_n = \frac{a_1(1 - r^n)}{1 - r}[/tex]
In this problem, the first term and the common ratio are given as follows:
[tex]a_1 = 2, n = 3[/tex]
Hence the equation is:
[tex]a_n = 2(3)^{n - 1}[/tex]
The nth term is of 1458000, hence the number of terms of the sequence is obtained as follows:
[tex]a_n = 2(3)^{n - 1}[/tex]
[tex]1458000 = 2(3)^{n - 1}[/tex]
[tex]3^{n - 1} = 729000[/tex]
[tex]3^{n - 1} = 3^{90}[/tex]
Then:
n - 1 = 90
n = 91.
Thus the sum of the sequence is given as follows:
[tex]S_n = \frac{a_1(1 - r^n)}{1 - r}[/tex]
[tex]S_{91} = \frac{2(1 - 3^{91})}{1 - 3}[/tex]
S = 2.62 x 10^(43).
