Use a graphing utility to graph V(x) = x(12- 2x)²​, which expresses the volume of a​ box, V, as a function of the length of the side of the square cut from each​ corner, x, of a sheet of square cardboard with a side length of 12 inches. Then use the trace button or maximum function feature to find the length of the side of the square that should be cut from each corner of the cardboard to create a box with the greatest possible volume. What is the maximum volume of the open​ box?

a. What is the length of the side of the square that should be cut from each corner of the cardboard to create a box with the greatest possible​ volume?

​(Round to the nearest inch as​ needed.)

b. What is the maximum volume of the open​ box?

_ in³ (round to nearest inch)

Consider the following two half-cells. One half-cell (half-cell A) initially has 1.0 M each of 3PG and GAP; the other half-cell (half-cell B) initially has 1 M each of NAD+ and NADH. What is the value of ΔG°’ (in kcal/mol to the nearest tenths) when the two half-cells are connected by a salt bridge. To answer this question, you will need the standard reduction potential of NAD+ (which is given in your text), and you will need the standard reduction potential of 3PG (i.e., 3PG + 2H+ + 2e- --> GAP + H2O), which is not listed in your text but which I will provide for you. This value is -0.55 V.

Standard reduction potential for NAD+ -> NADH is -0.32 V.

After review, we should understand that the social determinants of health are real, and they have real consequences. Watch two related videos on social determinants of health below. One was given by Prof Michael Marmot and another one was provided by WHO. After you watch the videos, discuss in this forum: What you have learned from the videos? In your opinion, what are key issues in addressing social determinants of health? And how?

(iv)

SFC company

Final dividend change  14.00-13.00=1.00

Three days excess return=7.14%-0.84%=6.3%

Two days excess return=10.13%-0.40%=9.73%

(v)

SNL company

Final dividend change=3-4.25=-1.25

Three days return excess: -1.21%+1.21%=0

Two days return excess: -1.21%-0=-1.21%

OGC company

final dividend=1-2=-1

three days return excess= -6.02% -2.39% = -8.41%

two days return excess= - -7.47% - 0.19% = -7.66%

A parallel plate capacitor with plate separation d is connected to a battery. The capacitor is fully charged to Q Coulombs and a voltage of V. (C is the capacitance and U is the stored energy.) Answer the following questions regarding the capacitor charged by a battery. For each statement below, select True or False.

After being disconnected from the battery, inserting a dielectric with κ will increase C.

With the capacitor connected to the battery, inserting a dielectric with κ will decrease U.

After being disconnected from the battery, decreasing d decreases C.

With the capacitor connected to the battery, decreasing d increases U.

After being disconnected from the battery, inserting a dielectric with κ will increase V.

With the capacitor connected to the battery, increasing d decreases Q.
