13 people are required to do so
Answer: 207/4 or -51.75
Step-by-step explanation:
Given: <span>f(x) = log3 (x + 1), look for f^-1 (2)
We are looking for the inverse of a function. The inverse of the function can be obtained by switching the variables and obtaining the values of the new function, before substituting f(2). Using a calculator:
</span><span>f^-1 (2) = 8</span>
Use ratio and proportion
5.25/x= 82/100
cross multiply
82 x= 525
x= 6.4 miles
