Answer:

Exponential growth A, B;

exponential decay C, E;

neither D.

Step-by-step explanation:

The function y=a\cdot b^x

  • represents exponential growth when b>1;
  • represents exponential decay when 0

A. The equation f(t)=\dfrac{2}{3}\cdot \left(\dfrac{7}{3}\right)^t represents exponential growth, because \dfrac{7}{3}>1.

B. The equation P=22\cdot \left(1.76\right)^x represents exponential growth, because 1.76>1.

C. The equation V=\dfrac{1}{3}\cdot \left(0.45\right)^x represents exponential decay, because 0

D. The equation W=3.2\cdot (x) represents neither exponential growth nor exponential decay, because this function is linear.

E. The equation g(x)=4.2\cdot \left(\dfrac{1}{3}\right)^x represents exponential decay, because 0

LekaFEV [45]

Answer:

  • 4 months

Step-by-step explanation:

Let the number of months be x

Alligator 1 weight = 4 + 2x

Alligator 2 weight = 8 + x

  • 2x - x = 8 - 4
  • x = 4

The answer is 4 months
