Which statement best describes the conditions for f ( x ) = a ( b ) x to be a model for exponential growth?
irina1246 [14]

Exponential functions grow is the base is greater than 1, while you have an exponential decay if the base is between 0 and 1. Finally, exponentials are not defined, as real functions, if the base is negative.

So, the answer is D, b > 1

The profits of mr cash’s company is represented by the equation p(t)=-3t^2+18t-4, where p(t) is the amount of profit in hundreds
Anika [276]

Answer:

  • $2300000- max profit
  • 5.77 years into operation - zero profit time

Step-by-step explanation:

<u>Given function:</u>

  • p(t)= -3t^2 + 18t - 4

It is a quadratic function with general form of y = ax^2 + bx + c

It opens down if a < 0 and gets maximum value at vertex which is determined at x = -b/2a

<u>For the given function vertex is:</u>

  • t = -18/-3*2 = 3

<u>Maximum value of p is:</u>

  • p(3) = -3*3^2 + 18*3 - 4 = -27 + 54 - 4 = 23 ($2300000)

<u>The time when profit is zero:</u>

  • -3t^2 + 18t - 4 = 0
  • 3t^2 - 18t + 4 = 0
  • t = (18 ± √18² - 4*3*4)/2*3 = (18 ± √276)/6 = (18 ± 16.61)/6
  • t = (18 - 16.61)/6 = 0.23 this is the time when company has just started to make profit, it is not applicable as is the past time
  • t =  (18 + 16.61)/6 = 5.77 years into operation, after this time there will be no profit
