Question

what is coefficient?

Answer 1

1.A numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g., 4 in 4xy).

Answer 2

what is a base?

Answer 3

a base is power that is raised
'base' refers to the number of digits used in a particular system of counting.

The binary system is base 2. i.e it uses 2 digits - 0 and 1... and is at the background off all computer mathematics.

Counting in binary starts at 0, with 0 = 0, and goes on to



1.1
2.10 ---- at this point digits start to be repeated

3.11
4.100
5.101
6.110
7.111
8.1000
9.1001
10.1010
11.1011
12.1100
13.1101
14.1110
15.1111
16.10000
17.10001
18.10010
19.10011
20.10100

Answer 4

In a mathematical equation, a coefficient is a constant by which a variable is multiplied. Consider the following equations:

3 x 2 + 5 x - 3 = 0
ax 3 + by 2 = z

The values 3 and 5 in the first equation are coefficients of x , a variable. In the second equation, if a and b are constants, then a is a coefficient of x 3 , and b is a coefficient of y 2 . It is customary to use lower-case, italic letters from the first half of the alphabet to represent constants whose values are not specified numerically. Lower-case, italic letters from the second half of the alphabet generally represent variables.

2) In physics and engineering, a coefficient is a quantitative expression of a specific property of matter, or of a phenomenon. Consider an electronic component whose value changes with temperature. It is tested and found to have a resistance of 100 ohm s at a temperature of +20 degrees Celsius (°C), and a resistance of 101 ohms at a temperature of +70 °C. This is the equivalent of a change in resistance of +1 ohm for a temperature change of +50 °C, or +0.02 ohm per degree Celsius. Between temperatures of +20 °C and +70 °C, therefore, this component has a temperature coefficient of +0.02 ohm per degree Celsius, assuming the resistance-versus-temperature function is linear over that range of temperatures.
