1. What is an extraneous solution of an equation?

Mathematics
1 answer:
Vadim26 [7]3 years ago
6 0
“Extraneous solutions are not solutions at all. They arise from outside the problem, from the method of solution. They are extraneous because they are not solutions of the original problem. ... To tell if a "solution" is extraneous you need to go back to the original problem and check to see if it is actually a solution.”

Basically, they are an answer you get when you solve a problem, but they don’t actually make the equation true so you disregard it.

N76 [4]
X=rcos∅=r cos (-210)=r cos 210=rcos (180+30)=-r cos 30
x=-r* \frac{sqrt 3}{2} = \frac{- sqrt 3r}{2} ,
y=r sin (-210)=-rsin 210=-rsin (180+30)=-r(-sin 30)
1or y=r sin 30=r* \frac{ 1}{2} = \frac{r}{2}

Find all zeros of the function
Pavel [41]

Answer:

x=-1,-3,2i and -2i

Step-by-step explanation:

By plugging in x=-1, f(x)=0 and x=-3,f(x)=0

That means x+1 and x+3 are roots of the fourth degree polynomial.

(x+1)(x+3)=x²+4x+3

Divide the polynomial by x²+4x+3 and that gives x²+4.

We now find the zeros of the factors

(x²+4x+3)(x²+4)=0

x=-1,-3,2i and -2i

How do you use slope-intercept (y= mx + b) equations to graph?
Colt1911 [192]

Answer:

M is the slope of the equation and basically the constant rate of change. So when there are two given points, the slope of the line between them will equal m.

B is the y-intercept. The "starting point" on the y-axis.

Y is the dependant variable and the unknown that the equation solves for.

X is the independant variable, the input.

To plot an equation, plug in random x values which solves for y. After plotting 2 or more points, you can simply connect them with a line. If it's not a straight line, some of your points are wrong.
