The problem lies in the intertia equation. You found the intertia of a disk around its center, not around its rim, as the problem calls for. The equation for inertia should be: I = 0.5mr^2 + mr^2 Therefore the coefficient when you solve should be 1.5 and not 0.5. Marianne was ...
State the vertex of the graph: y=2x-6x+9 ...the 2x is squared. y = 2x^2 -6x + 9 The vertex is where the function is a minimum. That would be where dy/dx = 4x -6 = 0 x= 3/2 If you are not familiar with calculus, then rewrite the expression y = 2 (x^2 -3x + (3/2)^2) +9 -(3/2)^2 ...

56%, what would the fraction and decimal be 56/100= 23/50 .56 is a neat fraction. What does it mean? How many hundredths is .56?
56% what would thefraction and decimal be 56% = 56/100 (which can be simplified by dividing both numerator and denominator by 4). Take your best guess for the decimal equivalent. We'll tell you if you got it right.
