56. If f(x) = x? - 2, then f(x + h) = ?

The term trigonometric function is known to be made up of functions such as sine (sin), cosine (cos), tangent (tan), etc., that stands for the ratios of sides of all right triangles.

To solve for tan $\frac{11\pi }{4}$

It will be $\frac{11\pi }{4}$ = 2 $\pi$ + $\frac{3\pi }{4}$

θ = $\pi -\frac{3}{4} \pi$

θ = $\frac{\pi }{4}$

To know the right angle,

θ = $\frac{\pi }{4}$ x 180/4 = 45⁰

tan θ = 1

Therefore, tan $\frac{11\pi }{4}$ = -1

According to Wilson, which of the following groups had too much power over the US economy and government? socialists big busines

oee [108]

Woodrow Wilson was of the opinion that when it came to power over the b,<u> Big Business</u> had too much of it.

Woodrow Wilson was not a fan of the power that big business had in the U.S. and so to combat it he introduced:

The Federal Trade Commission Act
Clayton Antitrust Act

These two acts were meant to reduce the monopolistic tendencies of big business in the United States and to increase competition in the market for the betterment of the American people.

In conclusion, Wilson was against big business.

Kp for the following reaction at a give temperature is 0. 263 at 1000. K: c(s) + 2 h2(g) ⇌ ch4(g) what is the total pressure (in

ratelena [41]

This problem is providing us with the reaction whereby methane is produced from solid carbon and gaseous hydrogen, as well as its Kp and asks for the total pressure at equilibrium for a specified addition of reactants. At the end, the answer turns out to be 11.7 atm.

<h3>Chemical equilibrium</h3>

In chemistry, when a chemical reaction takes place, it proceeds until a point called equilibrium, where the concentration of all the species start becoming unchanged. Thus, we can use equilibrium expressions whenever we needed pressures or concentrations at equilibrium.

In this case, for the reaction we were given, we can write the following equilibrium expression, where the solid carbon is excluded:

$Kp=\frac{p_{CH_4}}{p_{H_2}^2} =0.263$

Which can also be written in terms of the reaction extent and the initial pressure of hydrogen:

$0.263=\frac{x}{(p_{H_2}^0-2x)^2}$

Thus, we calculate the initial pressure of hydrogen with the temperature and volume of the flask:

$p_{H_2}^0=\frac{(4.50g/2.02g/mol)*0.08206\frac{atm*L}{mol*K}*1000K}{10.0L}\\ \\p_{H_2}^0=18.3atm$

Hence, we solve for x in the equilibrium expression as follows:

$0.263=\frac{x}{(18.3-2x)^2}\\\\x_1=6.64atm\\\\x_2=12.6atm$

Where the correct value is 6.64 atm because the 12.6 atm turns out into a negative pressure for hydrogen at equilibrium. Finally, we calculate the total pressure with:

$P_T=p_{CH_4}+p_{H_2}=x+18.3-2x\\\\P_T=6.64atm+18.3atm-2*6.64atm\\\\P_T=11.7atm$
