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

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.

The area of the given figure is 48 [tex]ft^{2}[/tex].
What is area?Area is a measurement of the space inside a two-dimensional shape. It is determined by multiplying the length and width of the shape together. Area is most commonly measured in square units, such as square feet, square meters, or square kilometers. When measuring curved shapes, the area is determined by measuring the space inside the shape and applying a mathematical formula to calculate the total area. Area is an important concept in mathematics and is used to measure surface area, volume, length, and other measurements. It can also be used to compare the sizes of different shapes.
Firstly, to calculate the area assume the figure as two separate rectangles. Think that you a drawing an imaginary line in the gap between the two 4-ft segments to make a line of 12ft in length.
To solve, multiply to find individual areas then add together to get the total area.
Given: The first rectangle is 5ft by 4ft.
We know, the area of a rectangle = Base × Height
[tex]4ft[/tex] × [tex]3ft[/tex] = [tex]12ft^{2}[/tex] .....(1)
The next rectangle is 12 by 3ft, as you have to add the missing length in the middle to accurately calculate the length of the line.
[tex]12ft[/tex] × [tex]3ft[/tex] = [tex]36ft^{2}[/tex] .....(2)
Adding (1) and (2) we get,
[tex]12ft^{2} +36ft^{2}[/tex] = [tex]48ft^{2}[/tex]

Which translation maps the graph of the function f(x) = x² onto the function g(x) = x² - 6x + 6?
left 3 units, down 3 units
Right 3 units, down 3 units
Left 6 units, down 1 unit
Right 6 units, down 1 unit
Answer: Based on the information you provided, it seems that the correct answer is "left 6 units, down 1 unit." This translation will map the graph of the function f(x) = x² onto the graph of the function g(x) = x² - 6x + 6.
To understand why this is the case, it helps to understand what the different parts of the function g(x) represent. The term x² represents the original function f(x) = x², the term -6x represents a horizontal translation of the graph of f(x) by 6 units to the left, and the constant term 6 represents a vertical translation of the graph of f(x) by 1 unit downward. Together, these transformations map the graph of f(x) onto the graph of g(x).
Note that if we were to apply the other translations you listed, they would not produce the correct graph. For example, if we were to apply a translation of "right 3 units, down 3 units," this would produce a graph that is shifted 3 units to the right and 3 units down, which is not the same as the graph of g(x). Similarly, if we were to apply a translation of "right 6 units, down 1 unit," this would produce a graph that is shifted 6 units to the right and 1 unit down, which is also not the same as the graph of g(x).

A ball is thrown directly upward from a height of 5 ft with an initial velocity of 24 ft/sec. The function s(t)=−16t2+24t+5 gives the height of the ball, in feet, t seconds after it has been thrown. Determine the time at which the ball reaches its maximum height and find the maximum height.
Answer:
The ball reaches 14 ft in 0.75 seconds
Step-by-step explanation:
[tex]h(t) = -16t^2+24t+5\\h'(t) = -32t+24\\[/tex]
The highest point occurs when the derivative is equal to 0, because the tangent line is horizontal at that point
[tex]-32t + 24 = 0\\24 = 32t\\t = \frac{24}{32}=\frac{3}{4}=0.75s\\[/tex]
plug t back into h(t) to get height
[tex]h(0.75) = -16(0.75)^2+24(0.75)+5\\=(-16)(9/16)+23\\=-9 + 23\\= 14 ft[/tex]
Note: If you are not familiar with the concept of derivatives yet, you can find the time of the highest point using the equation [tex]t =-\frac{b}{2a}[/tex] where [tex]h(t) = at^2 + bt + c[/tex]

a. Find the maximum height of the birdie.
The maximum height of the birdie is ___ feet.
b. How long does it take for the birdie to hit the ground?
About ___seconds
The ball may rise up to a height of 20 feet. and it will strike the ground in 1 second.
Describe height.Height is the vertical measurement from an object's top to its base. On sometimes, it has the designation "altitude."
The vertex at point (h,k) of a parabola, y = ax2 + bx + c, is first determined using the equation h = -b / 2a, and then that point is entered into the equation to determine k.
Let's now solve for h in this issue. We know that a = -16, b = 32, and c = 4 in the equation y = -16t2 + 32t + 4.
h = -b/2a
h = -(32) / 2(-16) (-16)
1 second is equal to h = -32/-32.
This means the the ball will reach it's maximum height after 1 seconds. But the problem is asking is for what that height is. So for our final step, let's plug in t=1 to our equation:
y = -16t^2 + 32t + 4
y = -16*(1)^2 + 32*(1)+ 4
y = -16 + 36
y = 20 feet
which means that the final answer is that the maximum height of the ball is 20 feet. and it will take 1sec to hit the ground.

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.
4. If the domain is x[tex]\geq[/tex]0, then 0 is the lowest we can plug into x.
y=2(0)+6
y=6
So, the answer is C. y[tex]\geq[/tex]6
You were on the right track :)
Keith drove to the mountains last weekend. There was heavy traffic on the way there, and the trip took 12 hours. When Keith drove home, there was no traffic and the trip only took 8 hours. If his average rate was 20 miles per hour faster on the trip home, how far away does Keith live from the mountains?
Do not do any rounding.
Keith live 480 miles far way from the mountains.
How far away does Keith live from the mountains?The distance between two locations is represented by the length of the line linking them. If the two points are on the same horizontal or vertical line, subtracting the various coordinates will show how far apart they are.
Consider the provided information.
Keith drove to the mountains last weekend. The trip took 12 hours because of the high traffic on the way there.
Let the distance is D and average rate or speed is x miles.
Distance = speed × time
Substitute the respective values.
D = x * 12
D= 12x
When Keith drove home, there was no traffic and the trip only took
hours. The average rate was 8 miles per hour faster on the trip home,
The average rate or speed during return is x+20 miles.
Substitute the respective values in the above formula.
D = (x+20) ×8
D= 8x+160
Equate both the equations.
8x+160 = 12x
4x= 160
x=160/4
=40
Substitute the value of x in D= 12x
D=12(40)
D= 480
Hence, Keith live 480 miles far way from the mountains.
