The exact value of the cosine of 11π / 12 will be given as negatice (1 + √3)/(2√2).

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The trigonometric expression is given below.

⇒ cos (11π/12)

We know that 11π/12 is equal to 165 degrees. Then we have

cos 165° = cos (45° + 120°)

We know that

cos (A + B) = cos A cos B - sin A sin B

Then we have

cos (45° + 120°) = cos 45° cos 120° - sin 45° sin 120°

cos (45° + 120°) = 1/√2 x (- 1/2) - 1/√2 x √3/2

cos (45° + 120°) = - (1 + √3)/(2√2)

Explanation:

The combined speed after the collision is -2.8 m/s.

Here we must have conservation of momentum, where momentum is the product between mass and velocity.

At the beginning, one of the players has a mass of 80kg and a velocity of 8m/s, so its momentum is:

P₁ = 80kg*(8m/s) = 640 kg*m/s

The other player has a mass of 120 kg and runs in the opposite direction at a speed of -10m/s (the negative sign is because of the direction). So its momentum is:

P₂ = 120kg*(-10m/s) = -1200 kg*m/s

The initial total momentum is:

P = P₁ + P₂ = 640 kg*m/s + ( -1200 kg*m/s) = -560 kg*m/s

At the end, the move together as a mass of (80kg + 120kg) = 200kg with a velocity V.

Such that the final total momentum is equal to the initial total momentum.

So we must have:

200kg*V =  -560 kg*m/s

V = (-560 kg*m/s)/200kg = -2.8 m/s.

The combined speed after the collision is -2.8 m/s.

Cell division is the process of the parent cell forming daughter cells. The decreased SA: V ratio does not affect the stages involved in cell division.

The surface area to volume ratio gives the size of the cell. The decrease in this ratio of the surface area and the volume causes the cell to divide or die. This ratio affects the rate of osmosis.

The decreased ratio also alters the signaling of the proteins and the cytoskeleton transport system of the cell, but the number of cell division phases is unaffected by the ratio.

Therefore, the cell division phases are unaffected by the SA: V ratio.

The depth of the diver when the air contains 47% recommended nitrogen is -0.3 ft

To answer the question, we need to know what an equation is.

An equation is a mathematical function that shows the relationship between two variables.

Given that he recommended percent p (in decimal form) of nitrogen (by volume) in the air that a diver breathes is given by p = 105.07d + 33, where d is the depth (in feet) of the diver.

To find the depth when the air contains 47% recommended nitrogen, we solve the equation with p = 47%

So, p = 105.07d + 33

47% = 105.07d + 33

0.47 = 105.07d + 33

0.47 - 33 = 105.07d

-32.53 = 105.07d

d = -32.53/105.07

d = -0.3096 ft

d ≅ -0.3 ft

Since p = 105.07d + 33

Making d subject of the formula, we have

d = (p - 33)/105.07

Substituting p = 47% = 0.47, we have

d = (0.47 - 33)/105.07

d = -32.53/105.07

d = -0.3096 ft

d ≅ -0.3 ft

So, the depth of the diver when the air contains 47% recommended nitrogen is -0.3 ft

The equation is balanced because the mass and charge are equal on both sides of the reaction equation.

In a nuclear reaction, one nucleus is transformed into another. In this case of the equation shown, the radon nucleus is being transformed into a polonium nucleus with the emission of an alpha particle.

The equation is balanced because a total mass of 219 is found on both sides of the reaction equation and a total charge of 86. Recall that an alpha particle is the same as a helium nucleus with a mass of four units and a charge of two units.

The measure of angle A to the nearest degree is 40 degrees.

Sine law can be used to find the measure of angle A in the triangle.

Therefore,

a / sin A = b / sin B

where

a  =210

b = 164

A = ?

B = 30 degrees

Hence,

210 / sin A = 164 / sin 30

cross multiply

0.5 × 210 = 164 sin A

sin A = 105 / 164

sin A = 0.64024390243

A = sin⁻¹ 0.64024390243

A =  39.7918194996
