Question 102873: PLEASE HELP TONIGHT if possible! This problem doesn't come from a textbook, but it is the only one on the worksheet that I cannot solve. Here it goes:
The graph of the square function (f(x) = x^2) has been transformed by rotating the graph about the x-axis, pushing the entire graph down 5 units, and then left 8 units.
Write the equation of the transformed graph.
Thanks so much! If you can get it to me tonight, that would be great, since it is due by midnight!!!

Question 105089: Thank you for any help you can give me.
*Solving Algebraic Equations - The graduate solves algebraic equations and constructs equations to solve real-world problems.
*Explain why an answer to an algebraic or numerical calculation is unreasonable.
*Task:
A. A school bus holds 57 students but is only 40% full. How many students are on the bus?
1. Explain why the answer of 22.8 students is unreasonable.
2. Give a reasonable answer in its place.
3. Explain why your answer is more reasonable.
B. The length of a rectangular field is 2 yards more than its width. Find the width if the area of the field is 120 yd2.

Question 105770: A small company produces both bouquets and wreaths of dried flowers. The bouquets take 1 hour of labor to produce, and the wreaths take 2 hours. The labor available is limited to 80 hours per week, and the total production capacity is 60 items per week. Write a system of inequalities representing this situation, where x is the number of bouquets and y is the number of wreaths. Then graph the system of inequalities.

Question 106515: Hello,
I've never tried this before, but I'm having a lot of difficulty understanding and remembering all the steps in solving large polynomial equations. One in particular is as follows:
a)Use Descartes Chart to show all possible combinations of positive, negative, and imaginary zeros.
b)Use Rational Zero Theorem to show all possible rational zeros to the given polynomial equation.
c)Find an upper bound and lower bound for all zeros using the Bounds Theorem.
d)Using the above information and synthetic division to find all real and imaginary zeros of the polynomial.
Thank you so much in advance for all your help. This stuff is so intense, and I'd like some help finding ways to remember everything that goes into this and when to apply it. Thanks again!

Question 107006: The degree three polynomial f(x) with real coefficients and leading
coefficient 1, has –3 and + 4i among its roots. Express f(x) as a
product of linear and quadratic polynomials with real coefficients.
a. f (x) = (x + 3)(x2 +16)
b. f (x) = (x + 3)(x 2 + 8x +16)
c. f (x) = (x + 3)(x 2 − 8x +16)
d. f (x) = (x − 3)(x 2 +16)

Question 106877: Here is one of the hardest problems I have even seen! Can you please see if you can help with this one? I feel like I can write some functions, but I am really confused.
CAN YOU PLEASE HELP ME WORK THIS PROBLEM OUT IN FULL PLEASE?
Product x: Each item sold produces $100 profit
Labor cost: is 3 hours for assembly, 1 hour in detail work, and 2 hours for QA & packing product.
Product y: Each item sold produces $150 profit
Labor cost: is 5 hours for assembly, 3 hour in detail work, and 2 hours for QA & packing product.
Company has these hours available for production for each accounting period:
3900 hours for assembly, 2100 hours for detail work, & 2200 hours for QA & packing.
Questions are:
1) How many products of both x & y should be produced to make a max & min profit?
2) Now what if product y profit goes up to $170 each. How many products are needed to make a max & min profit?
I know this is not an easy question, but do you think you could help with this question please? Thank you kindly.
