Find the values of y such that log2(11y-3)-log2(3)-2log2(​y) = 1

Find the values of y such that log 2 (11y-3)-log 2 3-2log 2 y = 1 Power law: 2log 2 y = log 2 y 2 Product law: log 2 (11y-3) - log 2 3 - log 2 y2 = log 2 (11y-3) - log 2 (3y 2 ) Quotient law: log 2 (11y-3) -...

Let y=arcsin(x-1), 0<=x<=2 (where <= means less than or equal to). Find x in terms of y, and show that dx/dy=cos(y).

First, the question asks us to find x in terms of y, or in other words, rearrange the equation to be in the form ' x= ' , rather than ' y= ', as it is currently. We start with y=acrsin(x-1) , as given in the...

The line l is a tangent to the circle x^2 + y^2 = 40 at the point A. A is the point (2, 6). The line l crosses the x-axis at the point P. Work out the area of triangle OAP.

This will involve drawing a diagram to aid your answer. Where O is the origin, A is a point on the circle and P is a point on the x-axis. OA is the radius of the circle. Line l crosses through point A and me...
