1.64 as a fraction = 1 16/25
ANSWER:}------> <u><em>line b</em></u>
Answer:
Option 4 (±1, ±1/3, ±3, ±9) is the correct option.
Step-by-step explanation:
The given expression is 
We have to find the possible rational zeros for the function.
So by the rational zero theorem factors will be
=±(Factors of constant term 9)/±factors of coefficient of 
=±(Factors of 9)/±(Factors of 3)
=±(1, 3, 9)/±(1, 3)
=±(1, 3, 9, 1/3)
So option 4 is the correct answer.
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
