Question 139988: hi,could you please help me solve this equation?
f(x)=(3x^5/2) Y^5/2 √25x^4y^4
I attempted to simplify the last part of the equation to 5x^2y^2, but then i got lost when i tried to simplify the whole thing together. thanks for your help in advance.

Question 141054: You provide the manager with a quadratic equation that models the expected number of ticket sales for each day x. (x=1 is the day tickets go on sale).
Tickets = -0.2x^2+12x+11
a. Does the graph of this equation open up or down? How did you determine this?
b. Describe what happens to the tickets sales as time passes?
c. Use the quadratic equation to determine the last day that tickets will be sold. (Note: Write your answer in terms of the number of days after ticket sales begin.)
d. Will tickets peak or be at a low during the middle of the sale? How do you know?
e. After how many days will the peak or low occur?
f. How many tickets will be sold on the day when the peak or low occurs?
g. What is the point of the vertex? How does this number relate to your answers in parts e and f?
h. How many solutions are there to the equation ? How do you know?
i. What do the solutions represent? Is there a solution that does not make sense? If so, in what ways does the solution not make sense?

Question 141931: Please,please,please I need your help! An application of a rational function is T = (AB)/(A+B), which gives the time, T, it takes for two worders to complete a particular task where A & B represent the time it would take for each individual worker to complete the identical task.
Estimate how long it takes you to complet a task of mowing the lawn in a given week. Suppose that Joe is slower than you to complete the task?
Include the type of job (mowing), the time it takes you and Joe individually to complete the job if you worked together. Include unit in your answer.
I don't have a clue. Please help...thanks in advance.

Question 141944: I am having difficulty trying to simplify radical equations that use exponents.
The problem I ma trying to solve is:
5x{sqrt(448x^5y^3}-3y{sqrt(63x^7y}
I understand I am supposed to factor down the 448 and 63, but I am not sure what is supposed to happen with the exponents. Any help is greatly appreciated.

Question 142279: I would really appreciate help on this problem. It is multiplying radicals.
the square root of 3x^3 divided by the sqaure root of 4y^2 times the sqaure root of 9x^2 divided by the square root of 2y^4.
I thought that you multiplied the top and bottom by the bottom, which gets rid of the radical on the bottom, but it just isnt working out.

Question 142300: Okay I worked this problem all the way to the last step and now Im no sure if I should write zero or no solution. The original problem was the square root of 3x+3 (+1)=the square root of 3x+4. I got 3x+4=3x+4, now solving this out will leave me with 0=0. So would the answer be no solution or zero?

Question 142304: Im having trouble with this one. The sqaure root of 12x^2y^3 - the sqaure root of 27x^4y. When I tried to solve it I got 2xy^2the square root of y minus 3x^2the sqaure root of y. It just doesnt seem right to me.

Question 142299: I really need some help. the square root of 3x^4y^3 divided the sqaure root of 9xy^5 The only thing I thought to do was to put the problems vertical instead of horizontal and then get the square root of 9. Im not sure what the next step is.
