The diagram shows the circle x2 + y2 = 10 P lies on the circle and has x-coordinate 1 The tangent at P intersects the x-axis at Q. Work out the coordinates of Q.

Apopulation of 1500 insects grows exponentially, by a factor of 3 every week. select all equations that represent or approximate the population, p, as a function of time in days, t, since the time it was 1500.
