Describe the Squeeze Theorem as simply as possible.​

Mathematics

Tju [1.3M]3 years ago

Hey there,

The squeeze theorem shows if f(x)\leq g(x)\leq h(x) for all real numbers (-\infty,~\infty) then f(x) = h(x) but g(x) has to equal that as well.

Let's say we have [ \lim_{n \to \infty} (\frac{cos~x}{x}) ]

~Apply the theorem

Note that [ -1 \leq cos~x \leq  1 ] and [ \lim_{n \to \infty} (-\frac{1}{x})\leq \lim_{n \to \infty} (\frac{cos~x}{x})\leq \lim_{n \to \infty} (\frac{1}{x}) ]

~Apply the infinity property to every side but the middle

\lim_{n \to \infty} (-\frac{1}{x}) = 0

\lim_{n \to \infty} (\frac{1}{x}) = 0

So... \lim_{n \to \infty} (\frac{cos~x}{x})=0

Best of Luck!

Assuming a fair die, 
probability of winning 0.25 = (2/6) = 1/3
probability of losing 0.25 = (4/6) = 2/3

Expected win
= sum (proba.*winning)
=0.25*(1/3) + (-0.25)(2/3)
=-0.25/3
= - (1/12) dollars  (negative sign means expecting to lose)

For each diagram, describe a translation, rotation, or reflection that takes line ℓ to line ℓ′. Then plot and label A′ and B′, t
inn [45]

Answer:

  1. translate down 3
  2. reflect across the horizontal line through A

Step-by-step explanation:

1. There are many transformations that will map a line to a parallel line. Translation either horizontally or vertically will do it. Reflection across a line halfway between them will do it, as will rotation 180° about any point on that midline.

In the first attachment, we have elected to translate the line down 3 units.

__

2. Again, there are many transformations that could be used. Easiest is one that has point A as an invariant point, such as rotation CW or CCW about A, or reflection horizontally or vertically across a line through A.

Any center of rotation on a horizontal or vertical line through A can also be used for a rotation that maps one line to the other.

In the second attachment, we have elected to reflect the line across a horizontal line through A.

Getting 10% a month is the best option if she put $500 in.  That would be $50 the first month. $55 the second month etc. -- which would be more than the $500 in answer 1.
