How to tell if there is a horizontal asymptote?
Answers
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.
2x^3y + 18xy - 10x^2y - 90y Part A: Rewrite the expression so that the GCF is factored completely. (3 points)
Answers
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).

A) $1,257
B) $1,557
C) $1,559
D) $2,341
Answers
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.
Write the equation in standard form for the parabola with vertex (0,0) and directrix y=-6
Answers
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.

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
Answers
198 / 360 = 0.55 mousetraps per minute
no, 2 mousetraps per minute is not accurate
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.

Jacob and Isaiah are brothers. Their combined ages are 63. Jacob is 7 years older than Isaiah. How old are each of the boys?
Answers
x = 7 + y --> eqn 1
x + y = 63 --> eqn 2
Substituting eqn 1 to eqn 2, then solve for x and y:
(7+y)+y = 63
7 + 2y = 63
2y = 63 - 7
2y = 56
y = 56/2
y = 28
x = 28 + 7 = 35
Therefore, Jacob is 35 years old, and Isaiah is 28 years old.
Final answer:
To solve this problem, set up a system of equations and solve for the variables. Isaiah is 28 years old and Jacob is 35 years old.
Explanation:
To solve this problem, we can set up a system of equations.
Let's say Isaiah's age is represented by x. Jacob's age is then represented by x + 7, since he is 7 years older than Isaiah.
We know that the sum of their ages is 63, so we can set up the equation: x + (x + 7) = 63.
Simplifying the equation gives us: 2x + 7 = 63.
Subtracting 7 from both sides of the equation gives us: 2x = 56.
Dividing both sides of the equation by 2 gives us: x = 28.
So, Isaiah is 28 years old, and Jacob is 28 + 7 = 35 years old.

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.
