21 = 4.8
8 x 2.1 = 16.8 - 12 = 4.8
8/9 x 3/4
8x3 = 24
9x4 = 36
24/36 simplified is 2/3
8/9 x 3/4 = 2/3
3. Like many epic heroes, Beowulf faces many external conflicts and virtually no internal conflicts. In your opinion, does this make him more or less sympathetic than the heroes of today's stories? Explain your answer.
Answer:
Suppose N is the size of a population of radioactive atoms at a given time t, and dN is the amount by which the population decreases in time dt; then the rate of change is given by the equation dN/dt = −λN, where λ is the decay constant.
