What is the basic plot of Titus by Shakespere? It doesn't have to be detailed. I think it's about the guy who like kills someone and bakes them in the pie? i don't know if i have it right

inverse function question
Hey, I'm having trouble fully understanding absolute value graphs and I've been asked find the largest value of a so that f^-1 exists for the function: f: (-efinity,a) --> R where f(x)= logel2x-1l *note: i have used 'l' to represent the straight line indicat...

Ah, it's right. Thanks alot!

The cable of an elevator of mass M = 1020 kg snaps when the elevator is at rest at one of the floors of a skyscraper. At this point the elevator is a distance d = 18.4 m above a cushioning spring whose spring constant is k = 6500 N/m. A safety device clamps the elevator agains...

Physics
Um are you saying Wtotal = [(1020)(9.8)-6678] (18.4+x) ?.. In that case, I did the quadratic and got x=17.33m, but still wrong answer :( argg

Physics
Wtotal = [(1020)(9.8)-6678] 18.4 = 61051.2J 61051.2J = 1/2 (6500)x^2 x = 4.33m STill wrong :( Help

hi, i'd also really like some help for another binomial distribution question, i have no idea where to start... the question is: A manufacturer makes 10,000 ball point pens per day and estimates that 400 will be defective. She decides that if a random sample of 10 pens con...

binomial distribution
hey, i'd really appreciate some help with this question: A medical treatment is successful 75% of the time. A hospital wishes to treat a group of patients. How many patients should they take so that the probablity that all are cured is 1/10? I know that p=0.75 and q=0.25 b...
