-Chem2: Quiz on REDOX.
-Phy2: Answer the ff:
  • Giancoli, 5th ed. p. 72 (34, 35 only but if you want practice, you may answer 20, 22, 28).
  • (on a graphing paper) 34. (II) A projectile is fired with an initial speed of 40.0 m/s.
    Plot on graph paper its trajectory for initial projection angles of θ = 15°, 30°, 45°, 60°, 75°, and 90°. Plot at least 10 points foreach curve.

    (on an intermediate pad paper) 35. (II) A projectile is fired with an initial speed of 75.2 m/s at an angle of 34.5° above the horizontal on a long flat firing range. Determine (a) the maximum height reached by the projectile, (b) the total time in the air, (c) the total horizontal distance covered (that is, the range), and (d) the velocity of the projectile 1.50s after firing.

    Thanks to Lithium.

-Math4: HW7(1 whole sheet) find the zeroes of the following functions, show DRS (Descartes Rule of Signs), RRT (Rational Root Thm) and all solutions:
  1. y = x^3 - 6x^2 + 32
  2. y = x^4 - x^3 - 7x^2 - 14x - 24
  3. y = x^5 - 2x^2 - 9x - 6
  4. y = x^6 - 6x^5 + 9x^4 + 4x^3 - 16x^2 + 8x + 12.
