How to tell if there is a horizontal asymptote?
To tell if there is a horizontal asymptote, for rational functions, compare the degrees of the numerator and denominator; if they are equal, the asymptote is the ratio of their leading coefficients. If the numerator's degree is less, the asymptote is at y=0; if greater, there is no horizontal asymptote. Polynomials do not have horizontal asymptotes.
To determine if a function has a horizontal asymptote, we look at the behavior of the function as x approaches infinity (x →∞). For rational functions, the degrees of the numerator and denominator play a crucial role. If the degree of the numerator is equal to the degree of the denominator, the horizontal asymptote is the ratio of the leading coefficients of the numerator and denominator. For instance, as x approaches infinity, the term with the highest power dominates and the constant terms become less significant, leading to the horizontal asymptote at y = 1.
In a scenario where the degree of the numerator is less than the degree of the denominator, the function will have a horizontal asymptote at y = 0, since the function approaches zero as x increases without bound. Conversely, if the degree of the numerator is greater than the degree of the denominator, no horizontal asymptote exists because the function grows without limit.
Remember, polynomials do not have horizontal asymptotes, as their values continue to increase or decrease indefinitely with x.

To solve the quadratic equation x^2 - 10x + 15 = 0 by completing the square, we manipulate it to the form (x - 5)^2 = 10, then solve for x to get two solutions: x = 8.16 and x = 1.84.
Explanation:To solve the quadratic equation by completing the square, we need to manipulate the equation x^2 - 10x + 15 = 0 so it takes the form of (x - a)^2 = b, where a is half of the coefficient of x, and b is a constant.
First, we move the constant to the other side of the equation:
x^2 - 10x = -15
Next, we find the value that completes the square. This value is (10/2)^2 = 25.
Adding 25 to both sides, we get:
x^2 - 10x + 25 = 25 - 15
Now the equation is a perfect square:
(x - 5)^2 = 10
To find the solution for x, we take the square root of both sides:
x - 5 = ±10√10
x = 5 ± √10
Thus, the solutions rounded to the nearest hundredth are:
x = 5 + √10 ≈ 8.16
x = 5 - √10 ≈ 1.84
The complete answer in the template is:
Form:
( x - 5 )^2 = 10

2x^3y + 18xy - 10x^2y - 90y Part A: Rewrite the expression so that the GCF is factored completely. (3 points)
To factor 2x^3y + 18xy - 10x^2y - 90y, find the GCF of the terms, rewrite the expression, factor out the GCF from the terms inside the parentheses, and simplify the expression.
Explanation:To factor the expression 2x^3y + 18xy - 10x^2y - 90y, we can begin by finding the greatest common factor (GCF) of the terms. The GCF of the coefficients is 2, and the GCF of the variables is y.
So, we can rewrite the expression as 2y(x^3 + 9x - 5x^2 - 45).
Next, we can factor out the GCF from the terms inside the parentheses. The GCF of x^3, 9x, -5x^2, and -45 is x. Factoring out x, we get x(x^2 + 9 - 5x - 45).
Finally, we simplify the expression inside the parentheses. Rearranging the terms, we have x(x^2 - 5x + 9 - 45). Combining like terms, we get x(x^2 - 5x - 36).

Write the equation in standard form for the parabola with vertex (0,0) and directrix y=-6
To find the equation of a parabola with a vertex at (0,0) and a directrix of y=-6, we determine the focus is at (0,6), leading to the standard form equation of the parabola as y = 1/4x^2.
Explanation:The question asks for the equation of a parabola in standard form given its vertex at (0,0) and directrix as y=-6. In parabolic equations, the standard form is usually y = ax^2 + bx + c for horizontal parabolas, or x = ay^2 + by + c for vertical parabolas. Given the vertex is at the origin (0,0) and the directrix is y = -6, this means the focus is at (0,6) because the distance from the vertex to the focus is equal to the distance from the vertex to the directrix but in the opposite direction.
For a parabola that opens upwards or downwards, the standard form is y = ax^2 (since the vertex is at the origin, b and c are 0). Given that the distance from the vertex to the focus (which is also the distance from the vertex to the directrix) is 6, the parabola opens upwards, and its focal distance (p) is 6. Hence, the value of 4p = 24, which leads us to conclude that a = 1/4. Therefore, the equation of the parabola is y = 1/4x^2.

Jamie has invested $1500 in a savings account. Each month the account pays an interest of 3.8%. How much money will she have in her account 4 years later if she does not make any deposits or withdrawals (round to the nearest dollar)?
A) $1,257
B) $1,557
C) $1,559
D) $2,341
Answer:
$4236.
Step-by-step explanation:
We have been given that Jamie has invested $1500 in a savings account. Each month the account pays an interest of 3.8%. We are asked to find the total amount Jamie will have in her account after 4 years.
We will use simple interest formula to solve our given problem.
[tex]A=P(1+rt)[/tex], where,
A = Final amount after t years,
P = Principal amount,
r = Interest rate in decimal form,
t = Number of years.
Let us convert our given rate in decimal form.
[tex]3.8\%=\frac{3.8}{100}=0.038[/tex]
Since the we have been given monthly interest rate, so we will convert the given rate to annual interest rate by multiplying 0.038 by 12.
Upon substituting our given values in above formula we will get,
[tex]A=\$1500(1+0.038*12*4)[/tex]
[tex]A=\$1500(1+1.824)[/tex]
[tex]A=\$1500(2.824)[/tex]
[tex]A=\$4236[/tex]
Therefore, Jamie will have $4236 in her account after 4 years.
A worker produced a total of 198 mousetraps during a 6 hour run with no rejects and no downtime. A report states that this worker produced at a rate of 2 mousetraps per minute. Based on the actual production, is the rate of 2 mousetraps per minute accurate?Exit Test
Based on the actual production, the rate of 2 mousetraps per minute is not accurate.
What is Rate?Rate of a quantity is the amount of that quantity with respect to some amount of another quantity.
If the quantity with respect to which the rate is measured is taken as single unit or one unit, then the rate is called unit rate.
Production of mousetraps by the worker in 6 hours = 198
Production of mousetraps by the worker in 1 hour = 198/6 = 33
That is, production of mousetraps by the worker in 60 minutes = 33
Production of mousetraps by the worker in 1 minute = 33/60 = 0.55
The worker produced mousetraps at a rate of 0.55 mousetraps per minute.
But the report states that this worker produced at a rate of 2 mousetraps per minute, which is not correct.
Hence the statement of report that the worker produced at a rate of 2 mousetraps per minute is not accurate, because he is only producing 0.55 mousetraps per minute.

The end points of AB are A(-2,-3) , B(3,2) point C lies on AB and is 2/5 of the way from A to . What is the coordinates of point C? Explain how you find your answer
To find the coordinates of point C which divides line AB into a 2:5 ratio, use the section formula. Therefore, the coordinates are (-4/7, -11/7). This provides point C's location on the line segment AB.
Explanation:The coordinates of C are determined through the section formula, which finds the coordinates of a point dividing a line segment into a specific ratio. In this case, the ratio is 2:5. To solve for the x-coordinate of C, the formula [(m*x2) + (n*x1)] / (m+n) is used, where m and n are the ratio values, x1 and x2 are the x-coordinates of points A(-2, -3) and B(3, 2). Using these, the x-coordinate of C is found to be (2*3 + 5*(-2)) / (2+5) = -4/7.
Similar calculations apply to solving for the y-coordinate of C: [(m*y2) + (n*y1)] / (m+n) = (2*2 + 5*(-3)) / (2+5) = -11/7.
Therefore, the coordinates of point C are (-4/7, -11/7). This is the point C on the line segment AB that is 2/5 of the way from point A to point B.
