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>
Her teacher would be 42. you would take 14 * 3 and get the teachers age.
Circumference of circular path=pi*d^2/4
=44.156
length of light=1.45
light needed=44.156/1.45
=31 approx
The answer is 16x because if you add 10 and 2 you get 12 then add 4 you get is 16 but you need to multiply by x so you write it as 16x
