Use the logistic growth model $f(x)=\frac{170}{1+8 e^{-2 x}}$ Find $f(0)$. Round to the nearest tenth.

Step 1 ：The logistic growth model is given by \(f(x)=\frac{170}{1+8 e^{-2 x}}\).

Step 2 ：To find \(f(0)\), we simply need to substitute \(x=0\) into the equation and calculate the result.

Step 3 ：After calculating the value of \(f(0)\), we find that it is approximately 18.9 when rounded to the nearest tenth.

Step 4 ：Final Answer: \(\boxed{18.9}\)
