If 12.89 + h = 36.77,then h = 23.88 after subtracting 12.89 from each side of the equation.
h = 63
If v = r * h then> r = v / h
h/9=7 multiply both sides by 9 h=63
h+1.5=8.4 subtract 1.5 from both sides h=6.9
h= -4
h/(-3 - 7) = 10h/-10 = 10h = -100
The equation (PE = mgh) represents the potential energy of an object near the surface of the Earth, where (PE) is the potential energy, (m) is the mass of the object, (g) is the acceleration due to gravity, and (h) is the height of the object above the reference point.
The answer to 9 times 7 equals 63. This is taught in math class.
The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.
Solving equations in two unknowns (r and h) requires two independent equations. Since you have only one equation there is no solution.
