find the equation of the tangent to y=x-(a^3/x^2) at the point (a,0) how to i work this out??can someone please show me how to do it step by step?thanks!!! Take the dervative of y y= x- a^3 x^-2 y'=1+2a^3/x^3 so the equation for the tangent is y= mx + b where m is y' a...
Rearrange to give d in terms of e: (3d-7)/(4+5d) = e I got 3d - 5de = 4e + 7 but where do I go from there? Thanks :) 1st you must Multiply the polynomial. Please try the tutorial at the following site: http://www.webmath.com/polymult.html
6/x + 6/x-5 = 1 I got to x^2 -17x +5 = 0 But I have no idea if that is right? How do I find the answer? Thanks 6/x 6/x-5 =1 multiply both sides by x x(6/x +6/x-5)= (1) x The denominator x will cancel giving: 6 + 6 --- = x -5 Now -5 into 6 = -1.2 so 6 -1.2= x x= 4.8

If g(x = log subscript 7 x then what is the value of g(1/49)? I believe it's 1/2 but I'm not sure. no recall that log 1/49 (base7) = log 1 - log 49 = 0 - 2 =-2
I believe that the domain for f(x) = log subscript 3 (1-x) is x is a real number I think the range for the same equation is y > 1 . the domain of log (1-x) would be such that 1-x > 0 -x>-1 x < 1 whereas the range would be y is any real number Have you considered wh...
I posted a problem earlier and made a mistake the question is what is the domain and range of f(x)= log subscript 3 (1-x)? Sorry! The answer is the same. The domain and range will be the same as if it were log base 40.
