bogdanovich [222]

Answer:

  • 2^45 or ≈ 3.5*10^13

Step-by-step explanation:

<u>Given equation</u>

  • f(t) = 2^(kt)
  • f - number of cells, t - number of months, k- coefficient

<u>We got 32 cells in the first month. It means:</u>

  • t = 1, f(1) = 32

<u>Using these numbers we can find the coefficient k:</u>

  • 32 = 2^(k*1)
  • 2^5 = 2^k
  • k = 5

<u>Then the equation becomes:</u>

  • f(t) = 2^(5t)

<u>Average time is 9 months, we can calculate the number of cells:</u>

  • f(9) = 2^(5*9) = 2^45 ≈ 3.5*10^13

Given f(x) and g(x) = k·f(x), use the graph to determine the value of k.<br> g(x)
djyliett [7]
<h2>Explanation:</h2>

The diagram for this exercise is attached below. We have two linear functions f(x) \ and \ g(x) and the following relationship:

g(x) = kf(x)

From the graph, we know that:

f(-3)=1 \\ \\ g(-3)=-3

Then, substituting into the relationship:

g(-3)=kf(-3) \\ \\ -3=k(1) \\ \\ \\ Finally: \\ \\ \boxed{k=-3}
