What are coeffcients?

Question

My teacher said we didn't need a graphing calculator, just a scientific calcuator that could do coeffcients.
What are coeffcients?
Can you give me an example?
Please name your source........THANK YOU =)

Answer 1

coefficient is any number(1,2,3,4,5,6 etc.) in front of a variable(a,b,c,x,y,z etc.)

for example:
5x
(5 is coefficient, and x is the variable)

7y+2x
(7 and 2 are the coefficient, and y and x are the variables)

z^2
(any variable with no number in front is always considered a 1 being the coefficient. in this case 1 is the coefficient, z is the variable, ^2 is the exponent)

hope this helped:)

Answer 2

Coefficients are the numbers in front of the variables. Variables are normally the alphabet a through z. If you have a variable that has no number in front of it the assumed Coefficient is 1.
Example: x^2 = 1x^2 the coefficient is the number 1
3x^2 = the coefficient of x is the number 3

Answer 3

Coeffcients are constant multiplicative factors. I.e 2x(squared) is 2.

Answer 4

coeffcients are the things that are known in an equation

EX: 5x+2=17
5,2,17 are the coeffcients and x is the variable.

Answer 5

i'm guessing which you advise that the downward stress of the item is a hundred Newtons. In a one properly-known Earth gravity (9.8 M/s/s) that should point the item has a mass of 100N/9.8M/s/s = 10.204 Kg (derived from f = ma) Now, because of the fact the airplane is tilted 'upwards' the stress exerted by using gravity could be broken down into 2 vector factors. the 1st one (oftentimes called the 'generic' stress) is at good angles to the prone airplane and the two'nd one (oftentimes called the 'parallel' stress) is parallel to the prone airplane. the conventional stress is given by using Fn = a hundred*cos(x) the place x is the perspective (measured from horizontal) of the airplane. The parallel stress is given by using Fp = a hundred*sin(x) the item will start to slip while Fp > .35*Fn yet, generally, we are saying that the item starts off to slip while the perspective, x, is larger than that discovered at Fp = .35*Fn making the substitutions a hundred*sin(x)/a hundred*cos(x) = .35 and tan(x) = .35 so as that x = arctan(.35) = 19.29 tiers the item will start to slip while the perspective of the prone airplane exceeds 19.29 tiers. observe additionally that the item will strengthen up on account that, as quickly because it starts off shifting, the coefficient of friction changes from the 'static' value to the 'dynamic' value (that's continuously decrease) as a effect, there'll be a internet stress on the item and, on account that f=ma, the item will strengthen up.

Answer 6

example 3x+4y=7x
the coefficients are 3,4,and 7.
It is any number in front of the variable!
Good luck!!

Answer 7

constants multiplied by a variable
3x²+5x+2y has coefficients of 3,5,2

Answer 8

Expression******Co- efficient
5 x ²******************5
3 f *******************3
9 y^5 ****************9

From above, it is seen that the coefficient is the number that goes in front of the letters.
