1- The population of mice in a field after n weeks is given by P = 500 x ( 1.12 )^n. A- How many mice were originally in the field?
B- How many mice were in the field after: i 10 weeks, ii 20 weeks?
C- Sketch the graph of P against n for n > 0.
D- How many weeks will it take for the mouse population to reach 2000?

2- The weight of bacteria in a culture hours after it has been established is given by the formula W = 20 x ( 1.007 )^t grams.

A- Find the original weight of bacteria in the culture.
B- Find the weight of the bacteria after 24 hours.
C- Sketch the graph of W against t for t > 0.
D- How long will it take for the weight to reach 50 grams?

hope this .

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
