Why are all sequences descrete in math

Mathematics
1 answer:
densk [106]3 years ago
3 0

Answer:

If you collect all the terms of the sequence into a set, that set will always be discrete, because there's only countably many of them, and every interval is uncountable. So you could move outside of natural numbers to real numbers, but then it's no longer a sequence, it's just a function.

Multiply.
DanielleElmas [232]

Answer & Step-by-step explanation:

<em>(x² - 5x)(2x² + x - 3)</em>

Multiply each term from the first expression into the second expression.

<em>2x⁴ + x³ - 3x² - 10x³ - 5x² + 15x</em>

Combine like terms.

<em>2x⁴ - 9x³ - 8x² + 15x</em>

So, after you multiply the expressions, your answer will be 2x⁴-9x³-8x²+15x.

IrinaVladis [17]

Answer:

No. Vivian will not make it to her friends house.

Step-by-step explanation:

If Vivian will be riding 15 miles per hour, and she has six hours , then in order to find out the distance, we will have to multiply the rate and the time.

Equation : 15x6 = 90

Using this solution, we can easily find out that 90 is less than 96 as shown.

90<96

In conclusion, no Vivian will not make it to her friends house within the 6 hours she has to get there.

Hope this helps!

How do I work with percents? Describe Please! ​
ella [17]
With what in regard? For fractions, percentage is relative to the amount “full”. Think or a bottle of water, if it’s 50% full, it’s got 1/2 (50/100) filled with water. Simplifying is the process of taking a big fraction, say, 12/36, and finding the similarity to reduce it. 12 and 36 are both even, so let’s try to divide it by 2. 12/2 is 6, and 36/2 is 18. 6/18. However this is simplified it is not in simplest form, so we can divide It again. 6/2 is 3, and 18/2 9. 3/9 can be reduced by 3, making 1/3. 1/3 is the simplest form.
