What is the inverse of the function f(x)=1/9x+2
Anna35 [415]

Answer:

f^{-1}(x)=9x-18

Step-by-step explanation:

we have

f(x)=\frac{1}{9}x+2

Let

y=f(x)

y=\frac{1}{9}x+2

Exchange variables x for y and y for x

x=\frac{1}{9}y+2

Isolate the variable y

x-2=\frac{1}{9}y

y=9(x-2)

y=9x-18

Let

f^{-1}(x)=y

f^{-1}(x)=9x-18 -------> inverse function

At a golf course there are 18 holes. Of the 18 holes 3 are par threes 8 are par fours and 7 are par fives what fraction of the h
elena55 [62]

The fraction of holes that are par three is \frac{1}{6}

The fraction of holes that are par four is \frac{4}{9}

The fraction of holes that are par five is \frac{7}{18}

<em><u>Solution:</u></em>

Given that At a golf course there are 18 holes

Therefore,

Total number of holes = 18

Of the 18 holes 3 are par threes 8 are par fours and 7 are par fives

So there are par 3, par 4 and par 5

Number of par 3 holes = 3

Number of par 4 holes = 8

Number of par 5 holes = 7

To find: fraction of the holes that are par threes Par fives and par fours

<h3><u>Find the fraction of par 3 holes:</u></h3>

\text{ fraction of par 3 holes} = \frac{\text{ number of par 3 holes}}{\text{ total number of holes }}

\text{ fraction of par 3 holes} = \frac{3}{18} = \frac{1}{6}

<h3><u>Find the fraction of par 4 holes:</u></h3>

\text{ fraction of par 4 holes} = \frac{\text{ number of par 4 holes}}{\text{ total number of holes }}

\text{ fraction of par 4 holes} = \frac{8}{18} = \frac{4}{9}

<h3><u>Find the fraction of par 5 holes:</u></h3>

\text{ fraction of par 5 holes} = \frac{\text{ number of par 5 holes}}{\text{ total number of holes }}

\text{ fraction of par 5 holes} = \frac{7}{18}

Thus the required fractions are found

IrinaK [193]
10 quarters....5 nickels......15 in total

probability of picking a nickel first is 5/15 which reduces to 1/3
without replacement
probability of picking a quarter next is 10/14 which reduces to 5/7

probability of both is : 1/3 * 5/7 = 5/21 <==

There are dependent events being that u didn't replace what u picked <==
