a) h(3x) = k
x
Find the value of k
b) Find the value of x when f(x) = g(2)
c) Find f
−1
(x)

its definatley   this on your answer choice?

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
