The vertex of this parabola is at (5, 5). when the y-value is 6, the x-value is -1. what is the coefficient of the squared term in the parabola's equation?

1/36  

Step-by-step explanation:

The vertex form of the equation for a parabola is

y = a(x - h)² + k

where h and k are the coordinates of the vertex

and a is the coefficient of x² in the standard form.

Data:

Vertex at (5,5)

A point at (-1,6)

Calculations:

1. Substitute the coordinates of the vertex into the equation

y = a(x - 5)² + 5

2. Substitute the coordinates of the point into the equation and solve for a

6 = a(-1 -5)² + 5

6 = a(-6)² + 5

6 = 36a + 5

1 = 36a

a = 1/36

The coefficient of x² in the standard form is 1/36.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
