S_3 is the vector space of polynomials degree <= 3. V is a subspace of poly's s(t) so that s(0) = s(1) = 0. The inner product for two poly. s(t) and f(t) is def.: (s,f) = ([integral from 0 to 1] s(t)f(t)dt). I would like guidance finding (1) an orthogonal basis for V and (2) the projection for s(t) = 1 - t + 2t^2. Thank you!

Design a three part, 1D, Kinematics problem, Solve it (finding the total time and distance traveled) and show it x(t), v(t), a(t) graph.

make the initial x(t) as zero but the initial v(t) can not be zero. for example, you could start at a constant speed, then slow to a stop, then speed up in the same direction (or go in reverse). Or you could start at certain speed, immediately speed up, then stay at that new speed for (say 200 meters) a while

Be sure to answer all parts. In acidic solution, O3 and Mn2+ ions react spontaneously: O3(g) + Mn2+(aq) + H2O(l) → O2(g) + MnO2(s) + 2H+(aq) E o cell = 0.84 V

Write the balanced half-reactions and calculate E o manganese when given E o ozone = 2.07 V.

Include states of matter in your answers.

You watched the documentary "Illicit: The Dark Trade". What in the documentary do you think was most interesting about globalization and crime? Why? Also, what would you have liked to see and learn in the documentary, but it was not there? In other words, what do you think was missing in the documentary that would have made us understand globalization of crime better if it were covered in the documentary?

Determine if the following sets are real vector spaces with the indicated operations.

(a) The set V of all ordered pairs (x, y) of real numbers with the addition defined by (x1, y1) + (x2, y2) = (x1 + x2, y1 + y2 + 1) and scalar multiplication defined by α(x, y) = (αx, αy + α − 1), α ∈ R

(b) The set V of all 2 × 2 real matrices X with the addition of M22 but scalar multiplication ∗ defined by α ∗ X = αXT , α ∈ R

Suppose an object falls from a great height on a planet where the constant of the acceleration of gravity is g = 7.84. Assume that the resistance of the atmosphere is proportional to the square of the velocity of the object with constant of proportionality k = 0.25. Establish and solve an Initial Value Problem to express the velocity of the object as a function of time. Find the terminal velocity of the object. Graph this function. Then express the fall distance as a function of time. Graph this function. Hint: g − kv2 = (√g − (√k)*v) (√g + (√k)*v)

For an element X, the following standard reduction potentials exist at a temperature of our study:

X^3+(aq) + 2 e– → X^+(aq) ε1° = 1.192 V

X^4+(aq) + 3 e– → X^+(aq) ε2° = 1.241 V

If [X^+] = 0.170 M, [X^3+] = 5.670 M, and [X^4+] = 0.174 M, at what temperature (in °C) will the galvanic/voltaic cell made from the above two half-reactions begins to become nonspontaneous?
