which rate of change represents the graph shown
a: -200 feet per minute
b: 15 feet per minute
c: 200 feet per minute
d: -15 feet per minute

D

Step-by-step explanation: Since this is depth, we know the answer should be negative. According to the y-axis, the submarine’s “depth below sea level” increases in negativity fast, so it could be answer choice A. BUT, the answer choices also include “per minute,” whereas the graph goes by 10 minutes. Therefore, D is the best option.

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.
