A certain colony of bacteria began with one cell, and the population doubled every 20 minutes. What was the population of the colony after 2 hours?

Note:
This is a logical question and doesn’t require any prior knowledge except the idea of multiplication. This could also be solved by simply making a table with an interval of 20 min and population which is multiplies by 2 in consecutive cells till we get 2 hours.

In the x - y plane, the graph of line   has slope 3 . Line k  is parallel to line   and contains the point  ( 3, 10 ). Which of the following is an equation of line k ?

Note:
The general equation of a line is  Ax + By = c. This form is modified to give us many other forms of equation of a line which involve the use of slope, x intercept, y intercept, etc. The student needs to be familiar with all these forms of equation of a line.
