While nursing, blue whale calves can gain weight at a rate of 200 pounds per day. Two particular calves weigh 6000 pounds and 6250 pounds at birth.
a.Write equations that model the weight of each calf as a function of the number of days since birth
b.How much is each calf expected to weigh 30 days after birth?
c.How are the graphs of the equations for part (a) related? Justify your answer.

Answer 1

a. 6000 + 200t
6250 + 200t

b. 6000+ 200*30 = 12000
6250 + 200*30 = 12250

c. parallel lines..
