Answer: 83.17
Explanation:
By definition, the dB is an adimensional unit, used to simplify calculations when numbers are either too big or too small, specially in telecommunications.
It applies specifically to power, and it is defined as follows:
P (dB) = 10 log₁₀ P₁ / P₂
Usually P₂ is a reference, for instance, if P₂ = 1 mW, dB is called as dBm (dB referred to 1 mW), but it is always adimensional.
In our question, we know that we have a numerical ratio, that is expressed in dB as 19.2 dB.
Applying the dB definition, we can write the following:
10 log₁₀ X = 19.2 ⇒ log₁₀ X = 19.2 / 10 = 1.92
Solving the logarithmic equation, we can compute X as follows:
X = 10^1.92 = 83.17
X = 83.17
Answer:
It prints "goodbye" 8 times.
Explanation:
The loop being described in this scenario would print "goodbye" 8 times. It would not include numbers detailing the range since the loop instructions only state for the system to print("goodbye") and nothing else. Also, it would only print it 8 times because in a range the endpoint is not included, this is mainly because in programming data structures tend to run on 0-based indexing.
Answer:
char str[5][100]
Explanation:
See attachment for options:
From the options, we can see that the programming language is C language.
The syntax to store an array of m strings with a maximum of n elements in C is:
char array-name[m][n]
In this case:
--- Number of strings in the array
--- Maximum character in each string
Assume the array name is str, the syntax can be expressed as:
char str[5][100]
Answer: The Standardized feature of Windows that make it easier to manage tools are:
1. Toolbar
2. Menu
3. Taskbar
Explanation: 1. Toolbar helps to easily show the various tools that can be used on Windows.
2. Menu helps to separate the different parts of the Windows for easy access.
3. Taskbar helps to show the various tools for doing a task.
