Answer:

0.5P - L

Step-by-step explanation:

P = 2S + 2L

P - 2L = 2S +2L - 2L

P - 2L = 2S

0.5P - L = S

Answer:

Step-by-step explanation:

P = 2S + 2L

2S + 2L = P

       2S = P - 2L

          S = \frac{P-2L}{2}

Please just (c)fog-¹​

<em>f(x)</em> = 1/(1 - <em>x</em>)

<em>g(x)</em> = (<em>x</em> - 1)/<em>x</em>

The inverse functions <em>f</em> ⁻¹<em>(x)</em> and <em>g </em>⁻¹<em>(x)</em>, if they exist, are such that

<em>f( f</em> ⁻¹<em>(x) )</em> = <em>x</em>

<em>g( g</em> ⁻¹<em>(x) )</em> = <em>x</em>

So we have

<em>f( f</em> ⁻¹<em>(x) )</em> = 1/(1 - <em>f</em> ⁻¹<em>(x) </em>) = <em>x</em>

Solve for <em>f</em> ⁻¹<em>(x)</em> :

1 = (1 - <em>f</em> ⁻¹<em>(x)</em> ) <em>x</em>

1 - <em>f</em> ⁻¹<em>(x)</em> = 1/<em>x</em>

<em>f</em> ⁻¹<em>(x)</em> = 1 - 1/<em>x</em>

<em>f</em> ⁻¹<em>(x)</em> = (<em>x</em> - 1)/<em>x</em>

and so <em>f</em> ⁻¹<em>(x)</em> = <em>g(x)</em>.

Similarly, you can solve for <em>g</em> ⁻¹<em>(x)</em> <em>:</em>

<em>g(</em> <em>g</em> ⁻¹<em>(x) )</em> = (<em>g</em> ⁻¹<em>(x)</em> - 1) / <em>g</em> ⁻¹<em>(x)</em> = <em>x</em>

1 - 1/<em>g</em> ⁻¹<em>(x)</em> = <em>x</em>

1/<em>g</em> ⁻¹<em>(x)</em> = 1 - <em>x</em>

<em>g</em> ⁻¹<em>(x)</em> = 1/(1 - <em>x</em>)

So we know <em>f(x)</em> and <em>g(x)</em> are inverses of one another,

<em>f</em> ⁻¹<em>(x)</em> = <em>g(x)</em>

<em>g</em> ⁻¹<em>(x)</em> = <em>f(x)</em>

Then

(a) (<em>f</em> o <em>g</em>)(<em>x</em>) = <em>x</em>

(b) (<em>g</em> o <em>f</em> ⁻¹)(<em>x</em>) = <em>g(g(x))</em> = (<em>g(x)</em> - 1)/<em>g(x)</em> = 1 - 1/<em>g(x)</em> = 1 - <em>x</em>/(<em>x</em> - 1) = 1/(1 - <em>x</em>)

(c) (<em>f</em> o<em> g</em> ⁻¹)(<em>x</em>) = <em>f(f(x))</em> = 1/(1 - <em>f(x) </em>) = 1/(1 - 1/(1 - <em>x</em>)) = 1/(<em>x</em>/(<em>x</em> - 1)) = (<em>x</em> - 1)/<em>x</em>

A kitten and a puppy found a sausage which is 14cm long and started eating it simultaneously from each end. The kitten is eating
julsineya [31]

It takes them 12 seconds to eat the whole sausage.

<h3>What is speed?</h3>

Speed is the rate of change of distance.

Analysis:

If kitten eats x cm, then puppy will eat 14 - x cm

speed = d/t

speed of kitten = 1/2

speed of puppy = 2/3

1/2 = x/t

2/3 = 14 - x / t

t = 2x--------1

2t = 3(14 - x ) -------- 2

substitute t in equation 2

2(2x) = 3(14 - x)

4x = 42 - 3x

7x = 42

x = 42/7 = 6cm

substitute value of x in equation 1

t = 2(60 = 12 seconds.

In conclusion, it takes the both animals 12 seconds to finish the sausage.
