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 ...

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!

P=2W+2L L=1.5W 480=2W+2(1.5W) solve for W, then go back and solve for L This is Pre-Cal?

c) and d) are correct for a) and the others I assume you used Calculus and the equation distance = -16t^2 + 320t to find your answers you must have set 1024 = -16t^2 + 320t after re-arranging and dividing by 16 this would give you t^2 - 20t + 64 = 0 (t-16)(t-4) = 0 so t = 16 ...

This is a long, long way from pre-calculus. 2,4 is in quadrant I when on any axis, it is not in a quadrant. In the case of 0,3 it is on the border between quadrants I,and II.

That's solvable easily with calculus, not sure whether you're supposed to be using it given your heading: C'(x) = 4.9(2)x - 617 = 9.8x -617.4 at its minimum, 9.8x = 617.4

If it is precalculus, you're not expected to use derivatives, which incidentally will give you x=0 as the answer. I do not know if you teacher has shown you a systematic method to calculate the minimum for a quartic. In this particular situation, we can find the answer rapidly...

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)

THIS IS FOR ALGEBRA/PRE-CALCULUS MATH. I POSTED IT JUST AS THE TEACHER WROTE IT.

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
