A cylinder's volume is given by (πx^3+4πx^2-3πx-18π cm^3). If the radius of the cylinder is (x+3) cm, what is the height in terms of x? ? Is antigravity a substance that exist now only in sci-fi novels? Will chemists one day in year million (far future) invent it eventually? An equation of motion is given by x=at^2+bt+c where a,b,c are unknown variables. If x=position and t= time, what are dimensions of a,b,c? ? How much longer would it take to mow an acre with a mower that has a 4 ft wide deck vs. one w/ a 6 ft wide deck (if moving at same speed)? Would you work in dredging?
