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:
Answer explained
Explanation:
From the previous question we know that while searching for n^(1/r) we don't have to look for guesses less than 0 and greater than n. Because for less than 0 it will be an imaginary number and for rth root of a non negative number can never be greater than itself. Hence lowEnough = 0 and tooHigh = n.
we need to find 5th root of 47226. The computation of root is costlier than computing power of a number. Therefore, we will look for a number whose 5th power is 47226. lowEnough = 0 and tooHigh = 47226 + 1. Question that should be asked on each step would be "Is 5th power of number < 47227?" we will stop when we find a number whose 5th power is 47226.
Answer:
A = 5 + 1.75r
Explanation:
Amount you have = $5
Earning per roll of wrapping paper = $1.75
Let
r = number of rolls of wrapping paper
A = Total amount earned
A = 5 + 1.75r
Equation that represents the total amount A (in dollars) you have after selling r rolls of wrapping paper is
A = 5 + 1.75r
I think this is true but like think about the computer hardware and stuff
For question one, Resnick skeptical of calling the young people of today 'digital natives' will have to be agree. For agreeable reasons is because people who are called "digital natives", is because they are in a technological state that they are familiar with. Which means that if young people are in a state of technology and they are really into it, you have this unbreakable string tied to the waist and it hangs into you from a tree. And for reason two, is because coding can be helpful. In situations like people hacking you, with coding, now that is when it comes in.
And for the others, I'll have to look at some more information I might have. But, here is your first answer is up above, If it isn't good enough, then let me know.
Hope this helps.
