For this question, please consider the hash function and the collision resolution method specified for the formative programming exercise.

For a$=21,$ c$=7$ and m$=30,$ what is the load factor $(2$ decimal places$)$ of the hash table after calling the function insert $20$ times? In the i$-$th call, the value to insert is given by $2*$i$*$i$+5*$i$-5.$ That is$,$ the first value to insert is $2,$ the second value is $13$ and so on$.$

Please, use a point as a decimal separator
