Answer:

Option A

Step-by-step explanation:

To check which function satisfies the graph, substitute the points. Points: $(1, 12)$ is on the graph. Substitute it on the functions given in the options.

Option A: $f(1) = 20 { (\ \frac{3}{5} )\ }^1$

$\implies 4 \times 3 = 12$

Other options do not fit this $(1,12)$ . Hence Option A is our answer.

How do you calculate it? You start by expressing the density in the units you have. Then you multiply by appropriate conversion factors to get to the units you want. Treat units as though they were any other variable. A value cancels that appears in both the numerator and denominator of a fraction.

$\dfrac{56.15\,kg}{0.222\,hh}\cdot \dfrac{1000\,g}{1\,kg}\cdot \dfrac{1\,pw}{1.55\,g}\cdot \dfrac{1\,hh}{238.5\,L}\cdot \dfrac{9.091\,L}{1\,pk}\\\\=\dfrac{56.15\cdot 1000\cdot 9.091\,pw}{0.222\cdot 1.55\cdot 238.5\,pk}\\\\ \approx6220\,\frac{pw}{pk}$
