<em>Question:</em>
<em>Triangles PQR and RST are similar right triangles. Which proportion can be used to show that the slope of PR is equal to the slope of RT?</em>
Answer:
Step-by-step explanation:
See attachment for complete question
From the attachment, we have that:
First, we need to calculate the slope (m) of PQR
Here, we consider P and R
Where
becomes
--------- (1)
Next, we calculate the slope (m) of RST
Here, we consider R and T
Where
becomes
---------- (2)
Next, we equate (1) and (2)
<em>From the list of given options (see attachment), option A answers the question</em>
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
