Answer: F = 25.1 kHz
Step-by-step explanation:
Time (period) = 250 × 10^-6 s
Let's first calculate the folding frequency. Given by
NF (rad s-1) = π/Δt
where NF = Nyquist frequency
t = time increment between observations.
The original signal must be filtered by analog or physical methods to remove all frequencies higher than the Nyquist frequency before the signal is sampled or digitized.
F = 3.143/0.00025
F = 12566.37Hz
minimum sampling rate = 2F
2 × 12566.37 = 25132.74Hz
minimum sampling rate = 25.1 KHz
Step-by-step explanation:
The degree of an algebraic expression is the largest exponent of the variable present. In expressions with multiple variables, the exponents of each variables are added.
First Expression;
pq: Degree = 1 + 1 = 2
p²q: Degree = 2 + 1 = 3
p²q²: Degree = 2 + 2 = 4
The degree of this expression is 4
Second Expression;
2y²z: Degree = 2 + 1 = 3
10yz: Degree = 1 + 1 = 2
The degree of this expression is 3
Answer:
for question two: 12
for question four: 1/3
for question six: 25.75 (rounded to two decimal places)
Answer:
20
Step-by-step explanation:
x-2y=6 and x+y=10
Multiply the second equation by 2
2x+2y = 20
Answer:
Yup the answer is 15!
Step-by-step explanation:
(3x + 4)^(1/2) = 7
3x + 4 = 49
3x = 45
x = 15
