| The distance, s, in meters, traveled by a particle is given by the formula s= 80t - 12t^2. Find the expression for velocity, and hence find the initial velocity. | v= 80 - 24t
initial velocity= 80m/s

| A rock is thrown vertically with an initial velocity of 40m/s from a point 5m above ground. The velocity of the rock after t seconds is given as: v= (40 - 10t) m/s Find s (t) | s (t)= 40t - 5t + c
s (t)= 40t - 5t + 5

| A rock is thrown vertically with an initial velocity of 40m/s from a point 5m above ground. The velocity of the rock after t seconds is given as: v= (40 - 10t) m/s Find the maximum height | When s'(t)=0, t= 4seconds
s(t)= 85m

| Factorize x^2 - 6x + 16 | (8 - x)(x + 2)
🗑
|

| Factorize 2x^2 - 2x - 12 | 2(x - 3)(x + 2)
🗑

| Find dy/dx when y= x^2 + 4x - 7 at the point (2,5) | dy/dx= 2x + 4 - 4 OR dy/dx= 2x
🗑
