Answer:
f(x) = 1500(0.97)ˣ
Step-by-step explanation:
Given that:
f(x) = abˣ
a is the initial bone density, that is the bone density at 0 years, x is the number of years and b is any real value. For an exponential growth, b > 1 while for an exponential decay, b < 1.
Since the bone has a current density of 1,500 kg/m³, hence a = 1500.
The density is lost at a rate of 3% annually, therefore b = 100% - 3% = 97% = 0.97.
Therefore substituting the values of a and b into the function gives:
f(x) = 1500(0.97)ˣ

Answer:
88 square units
Step-by-step explanation:
The area can be found using the formula ...
A = 2(LW +H(L+W))
A = 2(6·2 +4(6 +2)) = 2(12 +4(8)) = 2(44) = 88 . . . square units
