Answer:
Step-by-step explanation:
Given function is,
f(x) = ![\sqrt[3]{8x}+4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8x%7D%2B4)
To find the inverse of this function,
Rewrite the function as a equation,
y =
Interchange x by y and y by x,
x = ![\sqrt[3]{8y}+4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8y%7D%2B4)
Now solve this equation for y,
x - 4 = ![\sqrt[3]{8y}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8y%7D)
(x - 4)³ = ![(\sqrt[3]{8y})^3](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7B8y%7D%29%5E3)
(x - 4)³ = 8y
y = 
Now convert the equation into function,
Answer:
C
Step-by-step explanation:
Add all the marbles, you get 20.
count the number of non-red marbles, you get 15.
Now to find probability, you want a fraction, or a percentage, so either way, you write 15/20.
which simplified is 3/4
Answer:
5/12
Step-by-step explanation:
Answer:
1/4 month per book. other answer options: 0.25 or 25%
Step-by-step explanation:
If he is reading 8 books in two months, each number can be divided by 2 to get his number of books read in one month.
8/2 = 4
2/2 = 1
4 books per 1 month is equivalent to a quarter of a month per book. This means after each month, he will have 4 books read. After two months, he will have his 8 read.
