Suppose that the revenue R, in dollars, from selling x cell phones, in hundreds, is R(x) = -1.8x^2+ 154x. The cost C, in dollars, from selling x cell phones, in hundreds, is C(x)= 0.06x^3- 3x^2+ 55x + 200. (a) Find the profit function, P(x) = R(x) - C(x).
(b) Find the profit if x = 19 hundred cell phones are sold.
(c) Interpret P(19)

what graph

step-by-step explanation:

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.

well, if it's triangular garden, the triangle could represent the garden.
