Sam has 2 brothers. His brothers are 5 cm shorter and 7 cm shorter than him. Sam's height is 140 cm. What is the median height o

pochemuha

Answer:

The median height of Sam and his brothers is 135.

Step-by-step explanation:

First, let's find the age of Sam's brothers:

$B_{1} = 140 cm - 5 cm = 135 cm$

$B_{2} = 140 cm - 7 cm = 133 cm$

The median height of Sam and his brothers is given by the middle number of the three values arranged from lowest to highest:

133 <u>135</u> 140

<em>Since the middle number is 135, then the median height is 135. </em>

Therefore, the median height of Sam and his brothers is 135.

I hope it helps you!

In general, f−1(f(x)) = f(f−1(x)) =

Anestetic [448]

Answer:

f−1(f(x)) = f(f−1(x)) = x

Step-by-step explanation:

Follow this simple example using the function f(x) = x + 2

f(x) = x + 2

NOw we find the inverse function f^(1)(x).

y = x + 2

x = y + 2

y = x - 2

f^(-1)(x) = x - 2

The inverse function is f^(-1)(x) = x - 2

Now we do the two compositions of functions:

f^(-1)(f(x)) = x + 2 - 2 = x

f(f^(-1)(x)) = x - 2 + 2 = x

Both are equal to x.

Answer: f−1(f(x)) = f(f−1(x)) = x
