Hi there! f(18) makes the value of x 18 and x is the number of movies watched in 1 month. Therefore, A and C are eliminated because we’re talking 18 movies, not 18 months. B is also out, because Kelsey would pay more than $27 a month for the service, especially with the service fee. 18 * 1.50 is 27 and 27 + 12.50 is 39.50. Kelsey spends $39.50 a month watching 18 movies per month. The answer is D.
Okay so i would do this with a logarithm.
5^(2x) = 28
take the log of both sides
log5^(2x) = log28 and because of this log rule: logA^n = nlogA
(2x)log5= log28
then divide by log5 on both sides
2x = log28 / log5
and divide by 2
x = (log28 / log5) /2
this can be found with a calculator:
x= about 1.03521...
round that to whatever the question says to
the anwser is 36...................
Answer is about 3 times
About 3 times in April bc it’s saying It rained two times out of the 12 days in March in there about 30 days in March and 30 days in April so if you just add 12 and 12 equals 24 so it rained 4 times but if you are 12 it would equal 36 so if you would take half of 12 which is sixto equal one rainy day it would give you about 3 days
