1. Lucy and Ann want to purchase a house. The price of the house is $450,000 with 20% down payment. They are qualified for a 30-year loan at 4.5%. Calculate the anticipated monthly payments to the nearest two decimals.
The anticipated monthly payments for Lucy and Ann would be approximately $1,821.35.
To calculate the anticipated monthly payments, we need to consider the loan amount and the interest rate. The down payment for the house is 20% of the purchase price, which is $450,000 * 0.20 = $90,000. Therefore, the loan amount is $450,000 - $90,000 = $360,000.
Next, we need to calculate the monthly interest rate and the number of months. The annual interest rate is 4.5%, so the monthly interest rate is 4.5% / 12 = 0.375% (expressed as a decimal). The loan term is 30 years, which is equivalent to 30 * 12 = 360 months.
Using these values, we can calculate the anticipated monthly payment using the formula for a fixed-rate mortgage:
M = P * (r * (1 + r)^n) / ((1 + r)^n - 1),
where M is the monthly payment, P is the loan amount, r is the monthly interest rate, and n is the number of months.
Plugging in the values, we get:
M = $360,000 * (0.00375 * (1 + 0.00375)^360) / ((1 + 0.00375)^360 - 1)
M ≈ $1,821.35 (rounded to the nearest two decimals)
Lucy and Ann can anticipate monthly payments of approximately $1,821.35 for their 30-year loan at 4.5% interest rate, considering a $450,000 house price with a 20% down payment. It's important to note that this calculation does not include additional costs such as property taxes or insurance, which could affect the overall monthly expenses.

Pam and Erin start at the same point and begin rollerblading in different directions. Pam is rollerblading west at a speed of 2 miles per hour. Erin is rollerblading north at a speed of 4 miles per hour. After how many hours will they be exactly 14 miles apart? Round your answer to two decimal places
It will take 5.71 hours for Pam and Erin to be 14 miles apart.
If Pam and Erin start at the same point and rollerblade in different directions, then the total distance between them at any given time can be represented by the Pythagorean Theorem. The Pythagorean Theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse.
Let x represent the number of hours it takes for Pam and Erin to be 14 miles apart. Then, the distance traveled by Pam will be 2x, and the distance traveled by Erin will be 4x.
Using the Pythagorean Theorem, the equation that represents the distance between them can be written as 2x^2 + 4x^2 = 14^2.
Solving this equation, we get 6x^2 = 196, which can be written as x^2 = 32.75. Taking the square root of both sides, we get x = 5.71.

The value of the given sine function is √3/2, so the correct option is 2nd.
Given that an function Sin (-5π/3) we need to evaluate the expression,
To evaluate the trigonometric function sine of the angle (-5π/3), we can use the periodicity of the sine function.
Since the sine function has a period of 2, the sine of any given angle is equal to the sine of that angle plus or minus any multiple of 2.
To find an equal angle inside the main range (between -π and π), we can add 2 to the angle (-5/3).
Once adding 2:
(-5π/3) + 2π = (-5π/3) + (6π/3) = π/3
Now we can evaluate the sine of π/3, which is a commonly known angle. The sine of π/3 is √3/2.
Therefore, sin(-5π/3) = sin(π/3) = √3/2.
Hence the correct option is √3/2

Complete Question:-
Roller Coaster Crew
Ray and Kelsey have summer internships at an engineering firm. As part of their internship, they get to assist in the planning of a brand new roller coaster. For this assignment, you help Ray and Kelsey as they tackle the math behind some simple curves in the coaster's track.
Part A
The first part of Ray and Kelsey's roller coaster is a curved pattern that can be represented by a polynomial function.
Ray and Kelsey are working to graph a third-degree polynomial function that represents the first pattern in the coaster plan. Ray says the third-degree polynomial has 4 intercepts. Kelsey argues the function can have as many as 3 zeros only. Is there a way for the both of them to be correct? Explain your answer.
Kelsey has a list of possible functions. Pick one of the g(x) functions below and then describe to Kelsey the key features of g(x), including the end behavior, y-intercept, and zeros.
g(x) = x3 − x2 − 4x + 4
g(x) = x3 + 2x2 − 9x − 18
g(x) = x3 − 3x2 − 4x + 12
g(x) = x3 + 2x2 − 25x − 50
g(x) = 2x3 + 14x2 − 2x − 14
Create a graph of the polynomial function you selected from Question 2.
Part B
The second part of the new coaster is a parabola.
Ray needs help creating the second part of the coaster. Create a unique parabola in the pattern f(x) = ax2 + bx + c. Describe the direction of the parabola and determine the y-intercept and zeros.
The safety inspector notes that Ray also needs to plan for a vertical ladder through the center of the coaster's parabolic shape for access to the coaster to perform safety repairs. Find the vertex and the equation for the axis of symmetry of the parabola, showing your work, so Ray can include it in his coaster plan.
Create a graph of the polynomial function you created in Question 4.
Part C
Now that the curve pieces are determined, use those pieces as sections of a complete coaster. By hand or by using a drawing program, sketch a design of Ray and Kelsey's coaster that includes the shape of the g(x) and f(x) functions that you chose in the Parts A and B. You do not have to include the coordinate plane. You may arrange the functions in any order you choose, but label each section of the graph with the corresponding function for your instructor to view.
Part D
Create an ad campaign to promote Ray and Kelsey's roller coaster. It can be a 15-second advertisement for television or radio, an interview for a magazine or news report, or a song, poem, or slideshow presentation for a company. These are just examples; you are not limited to how you prepare your advertisement, so be creative. Make sure to include a script of what each of you will say if you are preparing an interview or a report. The purpose of this ad is to get everyone excited about the roller coaster.

what happens to an inequality sign when the inequality is multiplied or divided by a negative number
When an inequality is multiplied or divided by a negative number, the inequality sign will flip, meaning it will change its direction. For example, if you have a > b and you multiply or divide both sides by a negative number, the inequality will become a < b. This is because the relationship between the values reverses when multiplied or divided by a negative number.
Explanation:
When an inequality is multiplied or divided by a negative number, the direction of the inequality sign is flipped. This is because multiplication or division by a negative number, results in a reversal of the order of the numbers on the number line.
To see why this happens, consider the following example:
Suppose we have the inequality x < 5. If we multiply both sides of this inequality by -1, we get -x > -5. Notice that we have flipped the inequality sign from "<" to ">". This is because multiplying by -1 changes the sign of x to its opposite, and also changes the sign of 5 to its opposite, resulting in a reversal of the order of the numbers on the number line.
Similarly, if we divide both sides of the inequality x > 3 by -2, we get (-1/2)x < (-3/2). Here, we have again flipped the inequality sign from ">" to "<". This is because dividing by a negative number also changes the order of the numbers on the number line.
In general, if we have an inequality of the form a < b or a > b, where a and b are real numbers, and we multiply or divide both sides by a negative number, we obtain:
If we multiply by a negative number, the inequality sign is flipped. For example, if a < b and c < 0, then ac > bc.
If we divide by a negative number, the inequality sign is also flipped. For example, if a > b and c < 0, then a/c < b/c.
Therefore, it is important to be mindful of the signs of the numbers involved when performing operations on inequalities. If we multiply or divide by a negative number, we must flip the direction of the inequality sign accordingly.
