Find the distance between the points (-10, -9) and (-7, -1).

Distance: 8.5440037453175

Step-by-step explanation:

Distance: 8.5440037453175

Steps:

Distance (d) =√(-7 - -10)2 + (-1 - -9)2

=√(3)2 + (8)2

=√73

=8.5440037453175

Slope and Angle:

ΔX = -7 – -10 = 3

ΔY = -1 – -9 = 8

Slope (m) =  

ΔY

ΔX

=  

8

=2.6666666666667

θ =  

arctan(ΔY)

ΔX

=69.443954780417°

Equation of the line:

y = 2.6666666666667x + 17.666666666667

or

y =  

8x

3

+  53

When x=0, y = 17.666666666667

When y=0, x = -6.625

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.

people grow faster than other people.
