69: 16x^2+8x-3. I inserted this into the quadratic formula and got -8+/- the square root of (8^2-4(16)(-3)/(2 times 16). This reduced to -8+/- the square root of (64+120)/32, which further reduced to -8+/-the square root of 184/32. I reduced the top part to -8 +/- the square r...

A fire helicopter carries a 679 kg bucket of water at the end of a 15.2 m long cable. Flying back from a fire at a constant speed of 42.5 m/s, the cable makes an angle of 49.0o with respect to the vertical. Determine the force of air resistance on the bucket.
Your groceries are in a bag with paper handles. The handles will tear off if a force greater than 50.8 N is applied to them. What is the greatest mass of groceries that can be lifted safely with this bag, given that the bag is raised with constant speed.
You've just prepared a solution by transferring 20.0 g of glucose into a 1.0 - L volumetric flask, and adding water to the mark. Calculate the concentration of the glucose solution in terms of millimoles/Liter, mg/mL, and % (m/v). Ok, I think i'm overwhelmed by the wor...
