I'm studying analytic geometry and i came accross this question;"find the tangents common to x²+ y²=8 and y²=16x.How am i going to work it out,please? I tried to work out their gradients which gave me x²+y²=8 2x+2ydy/dx=0 dy/dx=-2x/2y =-x/y y²=16 2ydy/dx=...

What is the domain of 4w2 – 9/ –5w

What is the domain of y2 – 4 / 2y2 + y – 1

Sustainability is defined as

Both places did have some rivers which provided rich soil along the banks (depends on the river) which is good for irrigation.

Thanks
