Question about logic functions

Bacteria grow in a nutrient solution at a rate proportional to the amount present. Initially, there are 250
strands of the bacteria in the solution which grows to 800 strands after seven hours. Show (a) an
expression for the approximate number of strands in the culture at any time t and (b) the time needed for
the bacteria to grow to 1600 strands.

Figure 1 shows a system of two blocks A weighs 1800 N and B weighs 2200 N, are lying on inclined planes. The two blocks are connected by a uniform horizontal rod of weight 800 N. Determine (a) the reaction of each block on the plane surfaces (b) the compression force of the rod on blocks A and B (c) the value of force P to impend the block A upward. Take the coefficient of friction for all the surfaces as 0.3
