This is called in physics refraction phenomenon.

It occurs when light when the light passes from one medium with density d1 to another medium with density d2. The sight of the archer travel from air to deep into water & provokes a refraction.

So what score do I need to go to Duke University
Alex73 [517]
The 25th percentile New SAT score is 1450, and the 75th percentile SAT score is 1570. In other words, a 1450 places you below average, while a 1570 will move you up to above average. There's no absolute SAT requirement at Duke, but they really want to see at least a 1450 to have a chance at being considered.

What it means that [If x is a factor of p(x), what is the value of k?]
kompoz [17]

Answer:

k = -4

Explanation:

Given

P(x) = (3x^2 - 5)(x + k) - 20

x is a factor

Required

Solve for k

x is a factor means that the polynomial can be divided successfully by x.

In other words, x is a zero of the polynomial.

i.e.

x = 0 and P(x) = 0

Substitute 0 for x in P(x)

P(x) = (3x^2 - 5)(x + k) - 20

P(x) = (3*0^2 - 5)(0 + k) - 20

P(x) = (0- 5)(k) - 20

P(x) = (-5)(k) - 20

P(x) = -5k - 20

Substitute 0 for P(x)

0 = -5k - 20

Collect Like Terms

5k = - 20

Divide both sides by 5

k = -4

Moulin Beauty contest iterative elimination of weakly dominated strategies
LekaFEV [45]

Iterated elimination of strictly dominated strategies (IESDS) is a common technique that is used to get solutions to games that involve iteratively removing dominated strategies.

<h3>What is a weakly dominated strategy?</h3>

This refers to the type of strategy that delivers an equal or worse outcome than an alternative strategy.

Hence, we can see that in game theory, the use of strategic dominance is used when one strategy is better than another strategy for one player, not withstanding the efforts of the other player.

Therefore, this can be eliminated with the use of iterations to remove the weakly dominated strategies
