A square QR code contains 40×40 tiny squares (pixels) where each tiny square represents a 0 or a 1. Calculate how many bytes of data can be stored on the QR code
Answer:
Explanation:
QR Codes are made of multiple rows and columns. The combination of these rows and columns makes a grid of modules (squares). There can be a maximum of 177 rows and 177 columns which means the maximum possible number of modules is 31,329. With the eye, these are just small squares and mean very little, but the exact arrangement of those modules allows the QR Code to encode its data. This means that, unlike traditional barcodes which are 1 dimensional and use 1 row of lines, QR Codes use 2 dimensions which allows them to store a lot more data in the same area of space.

Answer:
Spread sheets
Explanation:
Charts are employed to display series of numeric data in a graphical format to help people understand large amounts of data and the relationships between them.
What is a worksheet?A worksheet is a sheet that is used as a guide in doing some work to make preliminary plans, supplementary computations, notes, or comments.
Charts are used to display a series of numeric data in a graphical format in order to help people understand large amounts of data and their relationships.
Good graphs allow for precise estimation of the quantities represented. The reader must understand the scale used to represent quantity on the graph in order to estimate quantities.
Create your graph with as few elements as possible. Color can help distinguish data sets in a graph, but avoid glaring color combinations (such as chartreuse and violet), as these can be distracting.
Vertical bars are used to describe information in column charts. They can work with a wide range of data, but they are most commonly used for information comparison. Line charts are excellent for displaying trends.
Thus, by using some things like this, one can make charts clearer.

a transmitter is operating at 150 MHz with a power of 3 W into a one-quarter wavelength vertical antenna. The receiver, which is 32.2 km away, has an antenna with a gain of 8 dB. What is the received power?
The received power will be 1.243 nW
We're given:
frequency [tex]f[/tex] = 150MHz
distance of the receiver [tex]d[/tex] = 32.2 km=32200m
Power of transmitter [tex]P_{t}[/tex] = 3W
Antenna gain = 8dB
To find :
Power received [tex]P_{r}[/tex]
[tex]P_{r}= \frac{P_{t} *G_{t}*G_{r}* \lambda^2 }{16*\pi^2*d^2}[/tex]
where [tex]G_{t[/tex] is transmit gain and [tex]G_{r[/tex] is receive gain as refrenced to isotropic source
⇒wavelength [tex]\lambda = \frac{c}{f}[/tex] where c is the speed of the light
⇒ [tex]\lambda = \frac{3*10^8}{150*10^6} =2m[/tex]
[tex]G_{t}= 1*1.64[/tex] ( value of [tex]dipole[/tex] = 1.64)
Now,
Antenna gain[tex]=8dB[/tex] ( in decibals)
⇒[tex]10log(x)=8[/tex]
⇒[tex]x=10^0^.^8=6.3095[/tex]
⇒ considering isotropic receiver
⇒[tex]G_{r}=6.3095*1.64=10.3477[/tex] ([tex]dipole[/tex] =1.64)
Now , using the formula
[tex]P_{r}= \frac{3 *1.64*10.3477 *2^2 }{16*\pi^2*32200^2}=1.2437*10^-^9[/tex]
Hence The received power will be 1.243 nW

Answer:
RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.
Explanation:
Answer:
RAM is random access memory - we can have it even after we shut down the computer. it is volatile .it stores temporarily.

If the 294.00 units are made and the cost per unit is $2.25 then variable expenses for the day is $661.5.
Given that 294.00 units are made and the variable cost per unit is $2.25
We have to find variable expenses for the day.
Total variable expenses for the day are a product of the output and the variable cost per unit.
So the variable expenses = no. of output x variable cost per unit
