Answer:
Cache is the fastest and most expensive, RAM is slower and less expensive, and virtual memory is the slowest and least expensive type.
Explanation:
Answer is A. The data has been filtered
The funnel in Excel lets you know that there is a filter in place on the columns. It is a filter icon. By default, any filtered column in Excel gets a little funnel icon on the top row as shown in the image attached. Once this funnel symbols is clicked, it gives you options to filter using several criteria.
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
As data travels further over a wavelength or frequency, the radiation type goes down.
<h3>What is an electromagnetic spectrum?</h3>
An electromagnetic spectrum can be defined as a range of frequencies and wavelengths into which an electromagnetic wave is distributed into.
In Science, the electromagnetic spectrum consist of the following types of energy from highest to lowest frequency and shortest to longest wavelength:
In this context, we can infer and logically deduce that as data travels further over a wavelength or frequency within the electromagnetic spectrum, the radiation type goes down.
