Which expressions are equivalent to 4^−2 ⋅7 ^-2? A. (4⋅7)^−4
B. 12/82^2
C. 7^−2/4^2
D. (4⋅7)^4

answer: the answer is e

step-by-step explanation:

the answer to your question is b.

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.
