In order to satisfy the condition, must have the 4th toss and 5th toss both being heads. Note that the 3rd toss must be tails as otherwise we would terminate the coin tosses prematurely. This leaves the f...

We start with parametric equations of x=2t+3 and y=3t^2+3t+2.
To find dy/dx, we need to work out either (dy/dt)/(dx/dt) or (dy/dt)*(dt/dx). This makes the dt's cancel each other out, allowing us to ...

So, for a standard liner function, Y=mx+c, where Y is the output, m is the gradient or slope of our line, x is the input value and c is our y-intercept, where our line crosses the Y-axis. So, we have two ...
