Express the partial sums (sn) of the following geometric series recursively (Remember all three parts): 100 + 20 + 4 + ⅘ + ….

its a straight line parallel to the time axis

a is the right answer

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.

d will be the best answer
