The answer would be b). -4 Reason being you have to minus four dollars to get to 14. If you chose c, then you would be adding four dollars, which isn't right. So your answer is b.
the right answer to the question is catch me on the root mean square velocity of gas molecule when measured by galvanometer to produce circular egg in the presence of light under blanket.
A ) This is a quadratic function: y = a x² + b x + c If the starting point is ( 0, 0 ) then c = 0 b ) The function is: y = - 0.2 x² + 3.6 x ( with coefficients to the nearest tenth ) The graph is in the attachment. c ) The roots: x 1 = 0, 0.2 x = 3.6 x = 3.6 : 0.2 x 2 = 18 d ) This is near the target ( 17 m ) . So the pumpkin will hit near the target.
