A block of wood has a mass of 6.0 g and a volume of 12.0 cm^3 . What is the density of the block of wood?

Density = 0.5 g/cm³

Explanation: Density is the ratio of mass per unit volume or D = m/V

D = m/V

= 6 g / 12 cm³

= 0.5 g / cm³

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
