Answer:

<h2>c. -0.432</h2>

Step-by-step explanation:

The given formula is

T_{n}=T_{1}(n)^{b}

Where T_{1}=200, T_{n} =15 and n=400. (givens of the problem).

Replacing and solving for b , we have

15=200(400)^{b} \\(400)^{b} =\frac{15}{200}= 0.075\\log((400)^{b} )=log(0.075)\\b(log(400))=log(0.075)\\b=\frac{log(0.075)}{log(400)}\\ b \approx -0.432

Therefore, the right answer is c.
