Answer:
Iv'e answered this question 2 times already lol. The purpose of speakers is to produce audio output that can be heard by the listener. Speakers are transducers that convert electromagnetic waves into sound waves. The speakers receive audio input from a device such as a computer or an audio receiver.
Explanation: I hope this helps!
So, this is an answer of your choice. What it is trying to ask is tell us what your dream home, job, husband, and so on. For example: My dream home is a mansion in Mississippi by the beach. My dream job is a doctor. Those are prime examples of a dream home and job. Now your answer shouldn't be the same as mine. Your's should be something different. Unless, you want a mansion in Mississippi by the beach and you would like to be a doctor. In other words it is asking you to tell us what you want you home, lifestyle, job, friends, and possibly your DREAM pet. Hope this helps.
Answer:
Option B is the correct answer for the above question.
Explanation:
The control structure is a decision type structure which can be either true or false. It has two options-- If this then, does this otherwise do this. When the user wants to write he control structure then he can do this by the help of the following syntax in python language--
if(condition):
do this
else:
do this
The above question wants to ask about the concept which is used in the programming for a decision then the answer is control structure which is referred from the option B. Hence B is the correct option while the other is not because--
- Option A states about the flowchart which is the picture form of the instruction.
- Option C states about the pseudocode which is the language form of the instruction.
- The operator is also not the correct option because it is used to perform the operation.
Answer:
The following code is written in java programming language:
//set if statement
if (((modelYear >= 1999) && (modelYear <= 2002) && (modelName == "Extravagant")) || ((modelYear >= 2004) && (modelYear <= 2007) && (modelName == "Guzzler")))
{
recalled = true; //initialized Boolean value
}
else //set else statement
{
recalled = false; ////initialized Boolean value
}
Explanation:
Here, we set the if statement and set condition, if the value of modelYear is greater than equal to 1999 and less that equal to 2002 and modelName is equal to "Extravagant" or the value of modelYear is greater than equal to 2004 and less than equal to 2007 and the model year is equal to "Guzzler", than "recalled" initialized to "true".
Otherwise "recalled" initialized to "true".
To accomplish this without using a loop,
we can use math on a string.
Example:
print("apple" * 8)
Output:
appleappleappleappleappleappleappleapple
In this example,
the multiplication by 8 actually creates 8 copies of the string.
So that's the type of logic we want to apply to our problem.
<span>def powersOfTwo(number):
if number >= 0:
return print("*" * 2**number)
else:
<span>return
Hmm I can't make indentations in this box,
so it's doesn't format correctly.
Hopefully you get the idea though.
We're taking the string containing an asterisk and copying it 2^(number) times.
Beyond that you will need to call the function below.
Test it with some different values.
powersOfTwo(4) should print 2^4 asterisks: ****************</span></span>
