The formula for estimating the number, N, of a certain product sold is N = 9200ln(5t + 3), where t is the number of years after
Lilit [14]
To determine the expected number of sales after 3 years of a product, we need an equation that would relate time with the number of sales. In this case, we use the equation above which expresses the number of sales as a function of time. We simply substitute the time which would be 3 years to the equation and evaluate the value of N. We do as follows:

<span> N = 9200 ln (5t + 3)
</span><span> N = 9200 ln (5 ( 3 ) + 3)
</span><span> N = 9200 ln 18
 N = 26591.42

Therefore, the correct answer would be option B. The number of sales after 3 years would be about 26591.</span>

The mnemonic SOH CAH TOA reminds you of the relationships between sides and angles in a right triangle. The one applicable here is ...

  Sin = Opposite/Hypotenuse

  sin(32°) = 20/x

  x = 20/sin(32°)

  x ≈ 37.74
