y = 25 - x^2 x _____ y 0 _____ 25 1 _____ 24 2 _____ 21 3 _____ 16 4 _____ 11 delta x = 1 so 25 + 24 + 21 +16 + 11 = 97 b the rectangles are all ABOVE the curve, so the estimate is OVER c do it now with x = 1, 2, 3, 4, 5 these rectangles are below the curve so under estimate r...

Mathematicians should not write navigation problems: an airplane has an airspeed of 430 miles per hour ***ON*** a ****HEADING**** of 135 degrees. the wind velocity is 35 miles per hour in the direction N30degreesE. Find the resultant speed and direction of the plane. Usually w...

Math books drive me crazy with their misuse of navigational language. You travel on a heading as used in the second sentence. A bearing is what direction you look to see something. (The enemy is on a bearing of 185 degrees true.) Anyway start at (x,y) = (0,0) It is heading 25 ...

The Americans considered the protection given by English troops to them at the expense of the English an "entitlement" to which they were entitled :)

v = t^2 - 6 t x = (1/3)t^3 - 3 t^2 + c x(6) = (1/3)(36*6) - 3 (36) + c = 72 - 108 + c = -36 + c x(5) = (1/3)(125) - 75 + c = -33.3 + c x(6)-x(5) = -36 + c +33.3 - c = - 2 2/3

What about 3 which I think is both a and c ?

3. The number of protons and number of electrons are equal for a neutral atom, therefore both. 4. When energy is ejected in the form of a radiated photon, the electron moves down in energy closer to the nucleus. The further the orbit is from the nucleus, the higher the energy ...

The ounce is the only weight measurement here. Kilograms measure mass not weight. However if this is elementary science they may not know that and would use kilograms for weight. weight = mass * local acceleration of gravity
