y=f(1/3x) & find new coordinates
Answer:
A(-3,0)
B(6,1)
C(15,0)
Step-by-step explanation:
To find the three new coordinates A,B,C we have to find out the equation of the original curve y=f(x) which is shown in the figure. We find that equation by using the turning point (2,1) which is point B and take any other point either A or C which intercept's the x-axis, i took C. We put both these points into the completing square formula of the curve.
[tex]y=a(x-h)^2+k[/tex]
where (h,k) are the turning points (2,1) respectively and C (5,0) corresponds to (x,y)
so the equations becomes
[tex]0=a(5-2)^2+1\\0=a(3)^2+1\\0=9a+1\\-1=9a\\a=\frac{-1}{9}[/tex]
So our equation y=f(x) becomes
[tex]y=-\frac{(x-2)^2}{9}+1[/tex]
now for
[tex]y=f(\frac{x}{3} )[/tex]
we replace the x in the original equation above with x/3 which changes the equation to
[tex]f(\frac{x}{3} )=-\frac{(\frac{x}{3}-2)^2}{9} +1[/tex]
and now we sketch the curve we have our hints for the new points A,B,C our hint is that the original points A and C are the x-intercepts so the new A and C lets name them A' and C' must be the x-intercepts as well and B is the turning point of y=f(x) so the new point B' must be the turning point of y=f(x/3)
so we simply sketch the curve y=f(x/3) use an online graph plotter if you know how to sketch it to save time or if you don't know you can ask me and i'll teach you cause learning to sketch isn't in the question so furthermore we sketch the curve i attached the figure in an image you check it out and the new points as well.
At a certain college, the ratio to men to women is 5 to 4. If there are 2,800 men, how many women are there?
Answer:
2240
Step-by-step explanation:
braniest pls
there are 2,240 women at the college.
To find the number of women at the college, we can use the ratio of men to women given and the known number of men.
The ratio of men to women is 5 to 4, which can be expressed as 5/4.
If we know that there are 2,800 men, we can set up a proportion:
5/4 = 2,800/x
To solve for x, the number of women, we cross-multiply:
5x = 4 * 2,800
5x = 11,200
Dividing both sides by 5:
x = 11,200 / 5
x = 2,240
Therefore, there are 2,240 women at the college.

If you were to describe a translation of triangle , what information would you need to include in your description?
these are 3 different questions. if you answer can u explain so it can help me please.
Answer:
ans of problem 12 is:
x=65
y=10
Answer:
Step-by-step explanation:
Problem 12:
I think that (2x-y)+60=(2x+y)+40
Because of the Alternate Interior Angles theorem, which places the 40 next to (2x+y) so then you know they are a linear pair. Same can be done for the side with the 60 degree angle. So both sides add up to 180 so they are congruent themselves and you can put them in this format:
(2x-y)+60=(2x+y)+40
-40 -40
We do this to remove the 40 from the right side completely, and whatever you do to one side of the equation you have to do to the other as well so remove 40 from both.
(2x-y)+20=(2x+y)
-2x -2x
Again, we are just trying to find out y right now
-y +20=y
+y +y
20 = 2y
10 = y
Then insert the y into an equation telling us that it is equal to 180 (because we know that from before) to get what x is
(2x-y)+60=180
We can also input our y that we found out was 10 from before:
(2x-10)+60=180
And now we can add up 60 and -10
2x+50=180
Now subtract 50 to both sides
2x=130
And divide both sides by 2
x=75
So x=75 and y=10

b.
The height is 162 inches
you can stack 5 boxes
Answer:
A. 27x<=150
B. x <=5 5/9
C. 5
Step-by-step explanation:
A. The amount of the boxes in inches has to be less than or equal to the storage unit in inches.
B. X is less than or equal to 27 divided by 150, which is 5 5/9.
C. Since you cannot have 5/9 of a box, you must round down and say that you can only stack 5 boxes vertically.
Work out the size of angle x
Answer:
Let's name the angle right close to 51 as c.
c = 180°-51° since angles on a straight line is equal to 180°.
so c= 129°
so x = 129° since it corresponds to c
Answer:
Step-by-step explanation:
Notice that the line that the variable x is on is equal to 180 degrees. Because the angle that it is next to is equal to 51 degrees, you subtract 180 from 51:
180-51=129
The final answer to this problem is 129 degrees.

The jazz band has m(variable) members. To raise money for a tour, each member sold 12 raffle tickets. Write an expression that shows the number of raffle tickets sold.
Answer: 12m
Step-by-step explanation:
Each member sells 12 tickets, so you would have to multiply the amount of tickets(12) by the amount of members(m).
=============================================
Explanation:
1 person sells 12*1 = 12 tickets
2 people sell 12*2 = 24 tickets
3 people sell 12*3 = 36 tickets
....
m people sell 12*m = 12m tickets
m is a placeholder for a positive whole number (1,2,3,...)
