A1. A particle is located at the origin. A second particle is a distance D away in a direction [E A N]. At the same time, the first and second particles suddenly move at constant speeds |v1| and |v2| in directions [E Θ1 N] and [W Θ2 N] respectively. If D = 25m, A = 30o, Θ1 = 50o and Θ2 = 35o and |v1| = 5.3m/s, what is |v2|, and at what time do they meet? [5 points]

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
