Verify the identity. Show your work.

cot θ ∙ sec θ = csc θ

Answers

To verify the identity, we can make use of the basic trigonometric identities:
cot θ = cos θ / sin θ 
sec θ = 1 / cos θ
csc θ = 1 / sin θ

Using these identities:
cot θ ∙ sec θ = (cos θ / sin θ ) ( 1 / cos θ)

We can cancel out cos θ, leaving us with
cot θ ∙ sec θ = 1 / sin θ
cot θ ∙ sec θ = = csc θ

A solution is known as a homogeneous mixture because _[blank]_.the solvent particles are uniformly dissolved in the mixture
the solvent fully dissolves in the solute
the solvent is always water
the solute fully dissolves in the solvent

Answers

Answer:

The solute fully dissolves in the solvent

Explanation:

This is because for a solution to be called a homogeneous mixture, all the solute must be dissolved in the solvent, without the particles of the solute being visible in the solvent.

According to modern atomic theory, it is nearly impossible to determine an electron’s exacta. color.
c. charge
b. position.
d. mass.

Answers

It is impossible to determine the exact position and momentum of electron simultaneously. Therefore, option B is the correct answer.

According to Heisenberg’s uncertainty principle,it is impossible to determine simultaneously, the exact position and momentum of an electron.

Mathematical expression  

ΔX.ΔP ≥ h/4π

ΔX = uncertainty in position

ΔP = uncertainty in momentum

h = Plank’s constant  

π= Pi  

Thus, we can conclude its nearly impossible to determine electron’s exact position. Therefore, option B is the correct answer.
