Which function represents the number of seconds, s, in d days? (hint: the number seconds in a day is 24 × 60 × 60 = 86,400.)
the function that represents the number of seconds, s, in d days is f(d) =

Suppose that the price p (in dollars) and the weekly sales x (in thousands of units) of a certain commodity satisfy the demand equation 4p cubedplusx squaredequals38 comma 400. determine the rate at which sales are changing at a time when xequals80, pequals20, and the price is falling at the rate of $.20 per week.

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)

10x − 5y + 14 = 0 whats the answer pls
