Prove that lim x->0 cos(1/x) does not exist.

1 answer:

5 0

The limit of the function cos(1/x) as x approaches zero can be determined by substituting x with zero to the expression given. IN this case, 1/0 is equal to infinity. Using the rule of cosines, the maximum value of the cosine expression is 1. Hence the limit should be 1.

Selma is about to purchase a new television that is listed for $415.99. If sales tax is 7.75%, what

Alex787 [66]

Answer:

448.23

Step-by-step explanation:

Sales tax is addition to the original price

The original price is 100%

First we find 1% of this, which is 415.99 / 100 = 4.1599

Then multiply this by 7.75 = 32.239225

Add this to the original price = 415.99 + 32.239225 = 448.229225

You have to round this to an appropriate number as the question uses two decimal places I think this will suffice = 448.23
