Write a rational function with an x-intercept at (-9,0), a vertical asymptote at x=3, and a hole located at (1,-5). Then, identify the horizontal asymptote.
Answers
Answer:
The rational function is [tex]f(x) = \dfrac{x^2 + 8\cdot x - 9}{x^2 - 4 \cdot x + 3}[/tex]
The horizontal asymptote occur at y = 1
Step-by-step explanation:
Given that the function has an x-intercept at (-9, 0), we have;
(x + 9) is a factor of the function
Also, given that the function has a vertical asymptote at x = 3, we have that a factor of the denominator of the function is (x - 3)
With a hole at (1, -5), we have, (x - 1) in both the numerator and the denominator and when x = 1, f(x) = -5
The general form of the function can be presented as follows;
f(x) = ((x + 9)·(x - 1))/((x - 3)(x - 1)) = (x² + 8·x - 9)/(x² - 4·x + 3)
Given that the power of the numerator and the denominator are equal, the horizontal asymptote occur at ratio of the leading coefficient of the numerator and the denominator which from the above equation is 1/1 = 1
The horizontal asymptote occur at y = 1

The tennis team has played 28 matches so far this season. They have won 10 matches so far. How many matches will the team need to win for the team to have a 55% success rate?
Answers
Answer: they would have to win 22/40 games
Step-by-step explanation:
22 divided by 40 is 0.55 or 55%
Answer:
x = 12 (I took the FLVS assignment for 04.04, and I'll show you guys how to do this!)
Step-by-step explanation:
The team has completed 28 matches so far and has won 10 of them.
The current success rate is:
[tex]r=\frac{10}{28} *1.00=.35714[/tex]
(1.00 = 100% and .35714 = 35.714%)
We need the success rate to be 55%
Then the team must win a number of "x" matches, so:
[tex]r=\frac{10+x}{28+x} =0.55[/tex]
Now we solve the equation for x:
[tex]\frac{10+x}{28+x} =0.55[/tex]
[tex]10+x=0.55(28+x)[/tex](distributive property here!)
[tex]10+x=15.4+0.55x[/tex]
Now, move the 0.55x to the other side by subtracting it from both sides:
[tex]10+x-0.55x=15.4[/tex]
And move the 10 by doing the same thing (subtracting from both sides):
[tex]x-0.55x=15.4-10[/tex]
[tex]0.45x=5.4[/tex]
(You might ask: 15.4 - 10 = 5.4, but how do you get 0.45x out of x - 0.55x? Use Quick Math, and you should get the answer!)
[tex]x=\frac{5.4}{0.45}[/tex]
[tex]x = 12[/tex]
So, by following these steps, x = 12 is your answer!
The team must win 12 matches to have a success rate of 55%.
Hope this helps! Have a wonderful day!

A train first travels east for 20 kilometers. Then it turns north and travels for 43 kilometers. Next it goes west for 20 kilometers. Finally, it travels south for an unknown number of kilometers. At the end of the journey, the train is back at the original location. How far did it travel southward?
Answers
Answer: the train traveled 43km southwards
Step-by-step explanation:
First, let's define.
North as the positive y-axis.
East as the positive x-axis.
And the initial position of the train is (0, 0).
Now, we know that:
"A train first travels east for 20 kilometers."
The new position will be:
(0, 0) + (20km, 0) = (20km , 0)
"Then it turns north and travels for 43 kilometers."
The new position will be:
(20km, 0) + (0, 43km) = (20km, 43km)
"Next it goes west for 20 kilometers."
If East if the positive x-axis, then West is the negative x-axis.
The new position of the train will be:
(20km, 43km) + (-20km, 0) = (0, 43km)
Then it travels south for an unknown number of kilometers, such that the final position is the same as the initial position, then if the train goes X kilometers to the south (and because North is the positive y-axis, South will be the negative y-axis), we have:
(0, 43km) + (0, -X) = (0, 0)
(0, 43km - X) = (0, 0)
Then we must have that:
43km - X = 0
43km = X
This means that the train traveled 43km southwards.
3(x + 2) = -5 - 2(x - 3) *
Answers
Answer:
x = -1
Step-by-step explanation:
3(x + 2) = -5 -2(x-3)
open parenthesis
3 * x + 3 * 2 = -5 + -2 * x + -2 * -3
3x + 6 = - 5 - 2x + 6
subtract 6 from both sides
3x + 6 - 6 = -5 - 2x + 6
3x = -5 -2x
add 2x from both sides
3x + 2x = -5 - 2x + 2x
5x = -5
divide both sides of the equation by 5
5x/5 = -5/5
x = -5/5
x = -1
