Find the inverse function

Alex

The inverse of this function is f(x) = $\frac{3x + 15}{4}$

To find the inverse of any function, start by switching the x and f(x) term. Then solve for the new f(x). The result will be the inverse function. The step-by-step process is below for you.

f(x) = $\frac{-15 + 4x}{3}$ ----> Switch the x and f(x)

x = $\frac{-15 + 4f(x)}{3}$ ----> Muliply both sides by 3

3x = -15 + 4f(x) ----> Add 15 to both sides

3x + 15 = 4f(x) ----> Divide both sides by 4.

f(x) = $\frac{3x + 15}{4}$

Unit rate for typing 34 words in a minute in a half

katrin [286]

Answer:

Rate is 1.1333 words per second 

Step-by-step explanation:

We understand rating as frequency or speed of doing something per time (seconds mainly)

${ \green{ \tt{rate = \frac{item \: quantity}{time} }}} \\$

Let's find rate in terms of seconds (words per second)

${ \rm{rate = \frac{34 \: words}{ (\frac{1}{2} \times 60) \: seconds} }} \\ \\ { \rm{rate = \frac{34}{30} }} \\ \\ { \rm{rate = 1.133 \: \: words \: per \: second}}$

b) 0.000244

Step-by-step explanation:

By the Fundamental rule of counting, there are

4*4*4*4*4*4 = 4,096

ways of forming six-digit arrangements where each position has 4 possibilities (1 to 4)

The probability of entering the correct code on the first try, assuming that the owner does not remember the code is

1/4096 = 0.000244
