The rational function that meets all the conditions is:
[tex]f(x) = \frac{-15}{(x - 3)*(x + 5)}[/tex]
How to find the rational function?
A rational function is of the form:
[tex]f(x) = \frac{p(x)}{q(x)}[/tex]
As the horizontal asymptote is at y = 0, we know that the numerator can't depend on x, so it is just a constant.
p(x) = a
And we want to have two vertical asymptotes at x = 3 and x = -5, then q(x) becomes zero at these values, so we have:
q(x) = (x -3)*(x + 5)
At this point, the function is:
[tex]f(x) = \frac{a}{(x - 3)*(x + 5)}[/tex]
Finally, we know that the y-intercept is 1, then we need to solve:
[tex]f(0) = 1 = \frac{a}{(0 - 3)*(0 +5)} = \frac{a}{-15} \\\\-15 = a[/tex]
Then we conclude that our function is:
[tex]f(x) = \frac{-15}{(x - 3)*(x + 5)}[/tex]

A university interested in tracking its honors program believes that the proportion of graduates with a GPA of 3.00 or below is less than 0.09. In a sample of 260 graduates, 20 students have a GPA of 3.00 or below. The value of the test statistic and its associated p-value are __________.
The test static value is 1.44 and its associated p-value is 0.1335.
Given that the problem deals with the concept of test for single proportion. The parameter of the interest is the population proportion of graduates with GPA of 3.00 or below is less than 0.09.
Let the population proportion be p=0.09.
Let the number of graduates in a sample be n=260.
Let the number of students have a GPA of 3.00 or below be x=20.
Based on the known data, the null and alternative hypothesis are,
H₀:p≥0.09
H₁:p<0.09
The sample proportion of students have a GPA of 3.00 or below is,
[tex]\begin{aligned}\hat{p}&=\frac{x}{n}\\ &=\frac{20}{260}\\ &=0.07\end[/tex]
Under the null hypothesis, the test static value is,
[tex]\begin{aligned}z&=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}\\ &=\frac{0.07-0.09}{\sqrt{\frac{0.09(1-0.09)}{260}}}\\ &=\frac{-0.02}{0.018}\\ &=-1.11\end[/tex]
The p-value for the left-tailed test is
p-value=p(z<-1.11)
p-value=0.1335
Hence, the value of the test statistic and its associated p-value for the proportion of graduates with a GPA of 3.00 or below is less than 0.09. are 1.44 and 0.1335.

Step-by-step explanation:
The population of classroom grows x squared in one year. the current population of classroom is 12. in one year. one the las day of the year, each person in the classroom eats 3 slices of pizza. if an entire pizza cost $26.60, how much money does a class spend per year on pizza. a pizza has 8 slices. (sorry if this makes no sense teacher made up on the spot)
The class spends $1436.4 per year on pizza. Since the population grows x² in one year, the strength of the class on the last day of the year is 12² = 144.
How to find the total population of the class in one year?It is given that,
The current population of the classroom is 12. I.e., x = 12
So, at the end of the year, the population of the class = x²
⇒ 12² = 144
Thus, the population of the classroom on the end day of the year is 144.
How many slices of pizza are required for this population in the class?It is given that,
On the last day of the year, each person in the classroom eats 3 slices of pizza.
So, 144 persons eat,
144 × 3 = 432 slices of pizza
Thus, 432 slices of pizza are required for the given population.
How much money does a class spend per year on pizza?It is given that,
A single pizza has 8 slices and every single pizza costs $26.60.
Since there are 432 slices, then the number of pizzas
= 432/8
= 54 pizzas
Then, the cost of 54 pizza's = 54 × $26.60 = $1436.4
Therefore, $1436.4 was spent on pizza per year.

Determine whether the given sequence could be geometric, arithmetic, or neither. If possible, identify either the common ratio or the common difference. 7, 9, 10, 12, ....
The sequence is neither geometric nor arithmetic
How to determine the sequence type?The sequence is given as:
7, 9, 10, 12, ....
Calculate the common difference to determine if the sequence is arithmetic;
d = 12- 10 = 10 - 9 = 9 - 7
Evaluate
d = 2 = 1 = 2
The above is false because 2 and 1 are not equal.
So, the sequence is not arithmetic
Calculate the common ratio to determine if the sequence is geometric;
r = 12/10 = 10 /9 = 9/7
Evaluate
r = 1.2 = 1.11 = 1.29
The above is false because the numbers are not equal.
So, the sequence is not geometric.

A college student takes the same number of credits each semester. Before beginning college, the student had some credits earned while in high school. After 3 semesters, the student had 41 credits, and after 6 semesters, the student had 68 credits. If C(t), is the number of credits after t semesters, write the equation that correctly models this situation.
Answer:
C(t) = 9t + 14
Step-by-step explanation:
write two equations with the given information
x + 6y = 68
x + 3y = 41
(x and y are just random variables, with x being the number of credits from high school and y being the number of credits earned each semester)
subtract (x+3y=41) from (x+6y=68) to get 3y=27
y = 9
then plug back in to one of the equations to find x
x + 3(9) = 41
x + 27 = 41
x = 14
then write the equation for C(t)
C(t) = 9t + 14
because you start with 14 credits from high school then add 9 credits for each semester taken

This question only requires to to substitute t = 0 and t = 1 into the equation to find the displacement.
Lets find the displacement at t = 0.
[tex]x(0)=4sin(\pi (0)+\frac{\pi }{2} )\\=4sin(\frac{\pi }{2} )\\= 4m[/tex]
Lets find the displacement at t = 1.
[tex]x(1) = 4sin(\pi (1)+\frac{\pi }{2} )\\=4sin(\pi +\frac{\pi }{2} )\\=-4m[/tex]

A cylindrical tank with radius 3 m is being filled with water at a rate of 4 m3/min. How fast is the height of the water increasing (in m/min)
Answer:
Let R be the radius of the tank, H(t) the height of the water at time t, and V(t) the volume of the water. The quantities V(t), R and H(t) are related by the equation
V(t) = πR²H(t) ___(1)
The rate of increase of the volume is the derivative with respect to time,
dV/dt
and the rate of increase of the height is
dH/dt
We can therefore restate the given and the unknown as follows
Given:
dV/dt = 4m³/min
Unknown:
dH/dt
Now we take derivative of each side of (1) with respect to t:
dV/dt = πR²dH/dt
So
dH/dt = 1/πR²dV/dt
Substituting R = 3 m and dV/dt = 4m³/min we have

Women can be seated in 89 ways.
Let Sn be the number of possible seating arrangements with n women. Consider n≥3 and focus on the rightmost woman. If she goes back to her seat, then there are Sn−1 ways to seat the remaining n−1 women. If he is sitting in the penultimate seat, then the woman who was sitting there before must now sit in the rightmost seat.

Keep the triangle that you created in part A. You will now copy the triangle to a different location on the grid using three of its sides:
In a different place on the grid, draw a new line segment that is parallel to and has the same length as AB. Label this segment DE.
Next, copy AC and BC . A reliable way to do this is to draw a circle centered on each endpoint of your new line segment. Make the radius of each circle equal to each of the lengths of the two remaining line segments on the original triangle. One of the intersection points of the two circles marks the third vertex of your new triangle. Place a point on the intersection, and label the point F.
Finish copying the triangle by drawing a polygon through the three points that you've established.
You should now have two triangles on the grid. What do you notice about the two triangles in terms of their size and shape?
