Suppose that a digitized TV picture is to be transmitted from a source that uses a matrix of 480 * 500 picture elements (pixels), where each pixel can take on one of 32 intensity values. Assume that 30 pictures are sent per second. (This digital source is roughly equivalent to broadcast TV standards that have been adopted.) Find the source rate R (bps).
Answers
Answer:
36,000,000 bps
Step-by-step explanation:
Matrix of 480 by 500 = 480 X 500 = 240,000 pixels
Intensity values per pixel = 32. This simply means the color variations in this TV.
The bit per pixel for an intensity value of 32 is 5 (That's 2 raised to the power of 5)
Pictures sent per second = 30
Source rate R (bps) = Total number of pixels in the matrix X bit per pixel X Number of pictures sent per second.
Source rate R (bps) = 240,000 X 5 X 30 = 36,000,000 bps
Final answer:
The source rate for the digitized TV picture is 230,400,000 bps.
Explanation:
The source rate can be calculated by multiplying the number of pixels per picture element by the number of intensity values per pixel and by the number of pictures sent per second.
So, the source rate R (bps) is given by:
R = (480 * 500) * 32 * 30
Calculating this, we find that the source rate is 230,400,000 bps.

Answer:
x = pi/2 + 2 pi n x = pi + 2 pi n where n is an integer
x = 5pi /3 + 2 pi n
Step-by-step explanation:
8 cos^2 x + 4 cos x-4 = 0
Divide by 4
2 cos^2 x + cos x-1 = 0
Let u = cos x
2 u^2 +u -1 =0
Factor
(2u -1) ( u+1) = 0
Using the zero product property
2u-1 =0 u+1 =0
u = 1/2 u = -1
Substitute cosx for u
cos x = 1/2 cos x = -1
Take the inverse cos on each side
cos ^-1(cos x) = cos ^-1(1/2) cos ^-1( cos x) =cos ^-1( -1)
x = pi/2 + 2 pi n x = pi + 2 pi n where n is an integer
x = 5pi /3 + 2 pi n

Answer:
Perimeter A = 122.5
Step-by-step explanation:
Set up the following proportion
The Perimeter of B = 12 + 9 + 9 + 5
The Perimeter of B = 35
7/2 = x/PerimeterB
7/2 = x / 35 Cross multiply
7*35 = 2x Combine the left side
245 = 2x Divide by 2
245/2 = 2x/2 Do the division
122.5 = x
The Perimeter of A = 122.5
Problem 3
If you compare the sides opposite the angle marked with a single arc, you will get the scale factor.
If these triangles are similar, and one of the sides opposite their markings will give you the scale factor
18/7.2 = x/1 where x is the scale factor going from the larger to the smaller triangle.
2.5 = x
So if you multiply the smaller triangle's sides by 2.5 you get the larger triangle.
