A 165 inch rod is leaning up against a wall, but is sliding down the wall so that the vertical distance between the top of the r
zalisa [80]

Answer:

the horizontal distance is increasing at a rate of 4.953 in/s

Step-by-step explanation:

since the rod is leaning up against the wall and its length L is constant , then the relationship between y ( vertical distance ) , x (horizontal distance ) and L is

x² + y² = L²

then using derivatives with respect to the time t in both sides of the equation

2*x*dx/dt + 2*y*dy/dt = 0

dx/dt = y/x*dy/dt

since we know that x² + y² = L² → x= √(L² -y²) , then

dx/dt = -y/√(L² -y²)*dy/dt

replacing values

dx/dt = -153 in /√[(165 in)² -(153 in)²]* (-2 in/s) = 4.953 in/s

therefore the horizontal distance is increasing at a rate of 4.953 in/s

It would be y\leq -2x-2 because the y-intercept is -2 and the slope is \frac{-2}{1}. Also, 0,0 does not fit in to the greater than equation.
