Step-by-step explanation:
A fraction is in simplest form when the top and bottom cannot be any smaller, while still being whole numbers. To simplify a fraction: divide the top and bottom by the greatest number that will divide both numbers exactly (they must stay whole numbers).
<span>gravitational potential energy : P
Gravity : g
Mass : m
height : h
P = mgh = 3 x 9.8 x 0.45 = 13.23 Joule
Potential energy is work , from the known formula
W = Fd ( work = force x distance )
W = P ( in case of potential energy height change)
F is the force acting on the body in case of ideal ramp , the only force acting is the weight of the body
F = mg ( not just <m> as the force is mg (Newton) gravity effect)
d is the displacement in direction of force, as we have considered the force to be the weight not it's component in direction of the ramp , the change in displacement is the change in height so
d = h
W = Fd = (F = mg) x (d = h) = mgh
W = mgh = P

Step-by-step explanation:
4^2+3(37-(2*5))
4^2+3(37-10)
4^2+3(27)
16+3(27)
16+81
=97
Answer: Scale of 2:1
Step-by-step explanation:
All the angles are the same. So its the same polygon just bigger.
Line DA multiplied by a factor of 2 will make is as long as Line ZW.
Line AB multiplied by 2 will also make it equal to Line WX
From that we can assume that Lines XY and YZ are equal to Lines BC and CD
