Our two points are (2,-3) and (8,-9). To find the distance between these two points, we can use the distance formula: d = \sqrt{(x_{2}-x_{1})^2 + (y_{2} - y_{1})^2 }.

Plug in values and solve for d:

d = \sqrt{(8-2)^2 + (-9 - -3)^2\\}

d = \sqrt{(6)^2 + (-6)^2}

d = \sqrt{36 + 36}

d = \sqrt{72}

The correct answer is C - \sqrt{72}

Hope this helps!! :)

You plan to acquire a sinusoidal signal that repeats 250 microseconds. What should be the minimum sampling rate of the digital s
Phoenix [80]

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

5. If we represent the length of a line by a,
Liono4ka [1.6K]

Answer:

Step-by-step explanation:Let a be the length of line

from question we know that

a+3 is another line

Here

a+(a+3)=15. ( Given in question )

2a = 15 -3

2a=12

a=12/2

a=6

Here a and a +3 are the length of the line

Finally ,6 and 9 are the lengths
