I LOVE Two & A Half Men!!!

How many people read books that they class as sexual literature, and what are they?

A parabolic satelitte dish has a diameter of 4m at a depth of 0.4m. Find the depth at which it's diameter is 3.5m, correct to 1 decimal place

Thanks lyounamu!!! It seems the days are gone when catching up on maths was simple!!!

Well I went 3x + 4y + 5 = 0 4y = -3x - 5 = 0 y = -3/4x - 1 1/4 Therefore y = -3/4x - 1 1/4 + 4 OR y = -3/4x - 1 1/4 - 4 y = -3/4x + 2 3/4 OR y = -3/4x -5 1/4 4y = -3x + 11 OR 4y = -3x - 21 3x + 4y - 11 = 0...

Ok I'm really not doing so well with this topic.... Find the equation of the locus of a point that moves so that its distance from the line 3x + 4y + 5 = 0 is always 4 units. I got 3x + 4y - 11 = 0 and 3x + 4y + 21 = 0 but the answers are 3x + 4y + 25 = 0 and 3x + 4y - 15 = 0 What have...

Ok I've got another one.... Find the equation of the locus of a point that moves so that it is equidistant from the point (2,-3) and the line y = 7.

Thanks! I've missed this stuff when I was away and am teaching myself, quess i just copied it out wrong.

Can someone tell me where i got it so wrong? The answer is x^2 - 12y + 36 = 0 Find the equation of the parabola with vertex (0,3) if it is concave upwards and a=3. (x-h)^2 = 4a(y-k)^2 (x-0)^2 = 4 x 3(y-3)^2 x^2 = 12(y^2 - 6y +9) x^2 - 12y^2 + 72y - 108 = 0
