Step-by-step explanation:
Step 1: Write our Givens
Move the constant term ,(the term with no variable) to the right side.
Here we have a negative 7, so we add 7 to both sides
Next, we take the linear coeffeicent and divide it by 2 then square it.
Then we add that to both sides
Next, we factor the left,
we got 5 because 5 add to 10 and multiply to 25 as well.
so we get
This is called a perfect square trinomial.
Next, we take the square root of both sides
± menas that we have a positive and negative solution.
Subtract 5 form both side so we get
The greater solution is when sqr root of 32 is positive so the answer to that is
1. Turn improper
2. set up the problem
now multiple across and simplefy
2. set up the problem
now multiple across and simplefy
Complete Question
A sensor output was acquired for 32 seconds at a rate of 200 Hz and spectral analysis was performed using FFT. If the data set was split into 5 segments (each 6.4 seconds long), what is the resulting:
a)F minimum
b) F maximum
c) Frequency resolution
Answer:
a)
b)
c)
Step-by-step explanation:
From the question we are told that:
Time
Frequency
Segments
Generally the equation for Frequency Range is mathematically given by
Therefore
a)
b)
c)
Generally the equation for Frequency Resolution is mathematically given by
Where
N=The Total dat points
N=Sampling Frequency *Time
Therefore
