Pre Calculus 12
Im going over my pre calculus 12 exam, and I need help with one question from the chapter Transformations of graphs and stuff. Combining Transformations 2y = f(5x-10)+8 The original points are (4,6) and the new points I got by translating it and stuff are : (14/5,20) But in ...

I am too embarassed to ask this Calculus (really pre-calculus) question in tutoring, because I know I should know. Is the inverse of f(x)=3x-1 actually f(x)=1/3x+1? How do I find it? What if it asks the same equation replaced with f to the -1 power (x)? I think I know how the ...

A quick analysis and sketch of the curve will show x-intercepts at -4,0, and 4 Since you want the area from 0 to 4, it will be the region above the x-axis. area = ⌠ 16x - x^3 dx from 0 to 4 ⌡ = [8x^2 - 1/4x^4] from 0 to 4 = (8(16) - 1/4(256)) - 0 = 128-64 = 64 I ...

Consider a class with 10 sophomores, 8 juniors, and 6 seniors. Two students are selected at random. 1) What is the probability of selecting 1 junior and 1 senior. 2) Find the odds of selecting two students who are not seniors. How do I set these up to solve?? Any help is ...

the total students are 24. Probability of 1junior and 1 senior are.. Pr=(8/24)(6/23) The second: Pr=(18/24)(17/23) Notice in each, the numerator is the number of possible ways to be successful,the denominator is the number of ways it can go.

Two cards are drawn from a standard deck of 52 cards. What is the probability of drawing 2 queens or 2 red cards? (4/52)(3/51)=1/221 ---drawing a queen (26/52)(25/51)=25/102--drawing a red card (1/221)(25/102)= 25/22542 drawing a queen or red card Is this correct?? Thanks for ...

No. You need to find the OR probability, a little tricker. And remember two queens are red... I cant do it better than this. Study it. http://en.allexperts.com/q/Basic-Math-657/Probability-5.htm

I am in Honors Pre-Calculus and am having a hard time understanding my teacher. I feel so stupid. Does anyone have any suggestions on a website that might give me some insight into what I am doing wrong? Thanks!

Ok I do not know how to do this problem. I know that csc is simply sin^-1 sin (- pi/12) csc ( (37 pi)/12 ok now I know this also sin (- pi /12 ) = - sin ( pi/12) not really sure how that helps I don't know were to go from here ( - sin (pi/12) )/(sin ( (25 pi)/12 ) )

Pre Calculus why is sin(-20)/cos 380 equal to tan (-200)

A class is given a list of eight study problems from which five will be part of an upcoming exam. If a given student knows how to solve six of these problems, find the probability that the student will be able to answer: (a) all five questions on the exam. (b) exactly eight ...

Method 1: use a graphing tool and enter the function. Method 2: Using several values for x, evaluate the function and plot the points (x,f(x)) to see the shape of the curve. If you can't evaluate f(x), then you might reconsider taking pre-calculus. As a starting point, note ...

Reiny you helped me with this logarithm yesterday: How did you write it out as log2 ( √A / B^3 ) Laws of logarithms combine, write as a single logarithm Need help on this question please, Im stuck, dont know where to go abouts from here: I did it on paint and uploaded it...

Looks like calculus not pre-calculus to me by the way. I do not see how to do it without taking the derivative.

a) when it hits the ground, f(t) = 0 0 = -16t^2 + 67t 16t^2 - 67t = 0 t(16t - 67) = 0 t = 0 or t = 67/16 = appr 4.19 seconds t=0 would be the start of the toss so the answer you want is t = 4.19 sec b) since you labeled it "pre-calculus" I assume you cannot at this point take ...

Pre-Calculus? That is a nasty equation. We might use Newton's Method, but that would be Calculus. I tried some "trial and erro" and got x = appr .371 using 2 decimals 4 sin .37 = 1.44646 e^.37 = 1.4477 I am curious what method was suggested that you should use.

P=2(W+L) A=WL, so L = 180/W so, P = 2(W+180/W) This is pre-cal, so you don't have calculus at your disposal. But, you do know that a square has maximum area for a given perimeter. So, W = L = √180 = 6√5
