A pulley system with a mechanical advantage of 15 is used to lift a 1750 N piano to a third floor balcony that is 7 m above the

devlian [24]

Answer:

The force is $E = 117 \ N$

Explanation:

From the question we are told that

The mechanical advantage is $ME = 15$

The load is $L = 1750 \ N$

The height is $h = 7 \ m$

Generally mechanical advantage is mathematically represented as

$ME = \frac{L }{E }$

Here E is the force that must be applied to move the piano

=> $E = \frac{L}{ ME }$

=> $E = \frac{1750 }{15 }$

=> $E = 117 \ N$

F(x)= 10x-5<br>What is the value of f-1(-4) ?

Afina-wow [57]

Answer:

$f^{-1}(-4) = \frac{1}{10}$

Explanation:

Firstly finding $f^{-1}(x)$

So,

$f(x) = 10x-5$

Substitute $y = f(x)$

$y = 10x-5$

Exchange the values of x and y

$x = 10y-5$

Solving for y

$x = 10y-5$

Adding 5 to both sides

$10y = x+5$

Dividing both sides by 10

$y = \frac{x+5}{10}$

Replace $y = f^{-1}(x)$

$f^{-1}(x) = \frac{x+5}{10}$

For x = -4

$f^{-1}(-4) = \frac{-4+5}{10}$

$f^{-1}(-4) = \frac{1}{10}$
