Answer:
54
Step-by-step explanation:
multiply 60 by 0.9 and you get 54..?
Let y = f(x)
y = ln(3x)
Exchange place with x and y.
x = ln(3y)
Solve for y.
y = (e^x)/3
Replace y with the inverse notation.
f^(-1) x = (e^x)/3
Done.
2t^2+1
Subtract t^2 from 3t^2 you get 2t^2
which is 2t^2+1 answer
So since a percent is out of 100 you would put 11/20 and right an equal sign next to that and the bottom fraction would be x/100. Then you would find the relationship between 100 and 20. 20 times 5 is 100 so then 11 times 5 is 55. 55% is your answer
The answer to the question is D
