A set of pulleys is used to lift a piano with a mass of 102 kg. The piano is lifted 3 meters in 1 minutes. How much power is use

agasfer [191]

Answer:

50.031 watts

Step-by-step explanation:

Formula

Power = Force * distance / time

The units are critical

distance = meters

time = seconds

force = newtons = kg * m / s^2

Solution

F = m * a

a = 9.81

m = 102 kg

F = 102 * 9.81 = 1000.62 Newtons

T = minute = 60 sec/min * 1 min

T = 60 seconds

d = 3 meters

Power = 1000.62 * 3 / 60

Power = 50.031

If f(x) and its inverse function, f Superscript negative 1 Baseline (x), are both plotted on the same coordinate plane, where is

bearhunter [10]

Answer:

(2,2)

Step-by-step explanation:

step 1

Find the equation of f(x)

is a line that passes through the points (0,6) and (3,0)

Find the slope

$m=(0-6)/(3-0)=-2$

The function f(x) in slope intercept form is equal to

$f(x)=-2x+6$

step 2

Find the inverse

Let y=f(x)

$y=-2x+6$

Exchange the variables x for y and y for x

$x=-2y+6$

Isolate the variable y

$2y=-x+6$

$y=-0.5x+3$

Let

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

$f^{-1}(x)=-0.5x+3$

step 3

Solve the system of equations

$f(x)=-2x+6$

$f^{-1}(x)=-0.5x+3$

equate both functions

$-0.5x+3=-2x+6$

solve for x

$2x-0.5x=6-3$

$1.5x=3$

$x=2$

substitute the value of x in any of the functions

$f(x)=-2(2)+6=2$

The solution is the point (2,2)

therefore

Their point of intersection is (2,2)
