In the real-world, humans hear sound as an analog signal. This means the signal
waveform, which is completely processable by human ears. However, machines 'hear' sound a little
differently, as they process sound digitally, which is a discrete waveform.
When sound is recorded or transmitted electronically, the continuous (analog) waveform is sampled to
convert it to a discrete (digital) sequence. Sampling is the process of reducing a continuous-time signal
to a discrete-time signal. As the sampling rate increases, the sound quality of the recording or
transmission will improve.
The graphs below represent two different samples of a pure tone. Sample 1 is taken 8 times per unit of
time. Sample 2 is taken 16 times per unit of time.

Answers

Answer: I hope i can help you guys unlike the other guy

Sample 2 would reproduce a better replication of the pure signal because it records more frequently, meaning that it would be closer to being a continuous waveform when compared to sample 1.

Step-by-step explanation:

Sample two has more double more the points compared to sample 1. Sample is closer to being a continuous wave form instead of a discrete waveform when compared to sample 1. The more points a graph has, the more accurate.

What is the length of a ramp with the highest point being 5 feet above the ground, and the base of the ramp being 12 feet horizontally? Find the length.

Answers

Answer:

5^2+12^2= c^2

25+144=c^2

169=c^2

find the square root of 169

the length is = 13 ft

Step-by-step explanation:

Answer:

13

Step-by-step explanation:

In this concept, it forms a right triangle because it is 5 feet high, the base is 12 feet horizontally, and you need to find the hypotenuse (the longest side of the triangle/the slanted side). In this case, you can use the Pythagorean Theorem, which is [tex]a^{2}+b^{2}=c^{2}[/tex], where a and b are the lengths of the triangle, and c is the hypotenuse.

-We know a and b already, which are 5 and 12. So substitute a and b in the equation:  [tex]5^{2}+12^{2}=c^{2}[/tex]

-Then, simplify to get:  [tex]25+144=c^{2}[/tex]

-Add the 25 and 144 to then get:  [tex]169=c^{2}[/tex]

-Find the square root of both sides to only get c left (the hypotenuse): [tex]\sqrt{169}=\sqrt{c^{2}}[/tex]

-Then you’ll get: [tex]\sqrt{169}=c[/tex], which simplifies to [tex]13=c[/tex]

A city is running out of phone numbers available for their population. They currently have 2,000,000 available phone numbers. They intend to create new area codes with the form ABC, where A can be digits 2-8, B can be digits 5-9, and C can be digits 5-9. How many TOTAL phone numbers will the city have after adding the new area codes?

Answers

Answer:

The total phone numbers, if the latter ABC is followed, will be 175.

Step-by-step explanation:

We are told that the digits will be in the form ABC and A can take values from 2 – 8, B from 5 – 9 and C from 5 – 9 as well.

This means:

A has 7 possible values (when you count the number of numbers between 2 and 8).

B has 5 possible values.

C has 5 possible values.

Therefore, the total phone numbers, if the latter ABC is followed, will be:

7 x 5 x 5 = 175.

Water runs from a hose into a bucket at a steady rate. The amount of water in the bucket for the time it is being filled is shown in the graph. “There are ____ gallons in the bucket after ____ seconds.”

Answers

Answer:

5 seconds 12 gallons of water

Step-by-step explanation:

since 5 equals 12 ur gonna divide the 12 into 3 split in in hakves then it will get u to 6 ow with 6 divide by 7 then aadd 8 the 8 will round up to 10 then 10 u have to split so thats 5 then 5 is gonna go intpo 9 then 9 will be divided into 7 so 9 divided by 7 is 1 2/7 now u take that and divide by 2 which is 0.2 then add 50 then subtract 50 then youll gett .2 then minus the 2 then u get 0.

The graph is the diagrammatic representation of a function thus the amount of water at the end of filling or at time 12 seconds is 5 gallons.

What is a graph?

A graph is a diametrical representation of any function between the dependent and independent variables.

For example, y = x² forms a parabola now by looking at only the graph we can predict the behavior of the function.

As per the given graph of the amount of water and time.

The graph is linear showing a steady rate.

The graph is finishing at the extreme right at coordinate (12,5) where 12 seconds and 5 are gallons.

So, at the end of the filling, the time taken is 12 seconds and the amount of water is 5 gallons.

Hence "The graph is the diagrammatic representation of a function thus the amount of water at the end of filling or at time 12 seconds is 5 gallons".

What was the price of the car before the sales tax was added?

Answers

Answer:

One big reason why a car’s total price won’t match the price on its window sticker relates to fees charged by a car dealership and the automaker. For example, although a car may cost $19,995 according to the window sticker, that figure might be the price before the addition of a destination charge, which is a pricy manufacturer’s fee that can add up to $1,000 to the price. A dealer may also charge a documentation fee to prepare the vehicle’s documents for sale, and this figure can sometimes cost as much as $500. There are mandatory government fees too, such as the cost to process the car’s title work or change the registration to your name.

Step-by-step explanation:

Dealer and manufacturer fees usually aren’t the biggest add-ons to a car’s purchase price. The priciest addition typically comes in the form of taxes, since most states levy a sales tax on the entire price of a new or used vehicle. Since sales taxes can range as high as 8-10 percent in some areas, this can easily add thousands of dollars to your vehicle’s purchase price. For example, a $20,000 car purchased in an area with a 7 percent sales tax will cost an extra $1,400 on top of the purchase price, while a $30,000 car bought in a place with a 9 percent sales tax will see a whopping $2,700 price boost before you can drive it home.

The distance between two train stops is 160 miles the train will travel 3/4 miles per minute how long will it take the train to reach it's destination

Answers

Answer:

3hours 55 minute

Step-by-step explanation:

Step one:

Given data

distance= 160miles

velocity = 3/4 miles per minutes

Step two:

Required:

time

we know that velocity is

v=distance/time

times= distance/velocity

time=160/3/4

time= 160*4/3

time=640/3

time=213.33333minuts

Time= 3hours 55 minute

Time taken to cover distance is 213.33 seconds.

Speed, Time and Distance:

Given that;

Distance between two bus stop = 160 miles

Speed of train = 3/4 miles per minute = 0.75 miles per minute

Find:

Time taken to cover distance

Computation:

Time = Distance / Speed

Time taken to cover distance = 160 / 0.75

Time taken to cover distance = 213.33 seconds
