4. Identify the term with coefficient -3 in the expression:<br> 9a3 + 4b2 - 3c + 11
Mrrafil [7]

Answer:

-3 is the coefficient of c.

Step-by-step explanation:

The given expression is :

9a³ + 4b² - 3c + 11

We need to find the term with coefficient -3 in the expression.

The coefficient is defined as a number or quantity placed with a variable.

The coefficient of a³ = 9

The coefficient of b² = 4

The coefficient of c = -3

Hence, -3 is the coefficient of c.

What is the 5-D process?
NemiM [27]
The 5-d process is the process in answering problems with things meaning
if you have amanda is x and jake is 3 times amandas age....and there mother is 4 times jakes age..and there sum of ages is ....its these kind of problems. so you have a step by step process to solve them...(but you can do it without and skip a few steps when doing it )
but here it is-->
1) describle or draw the problem
2) Define (define what varables you are using
3) Do (Set up equation and solve)
4)Decide (chekc ur answer)
5)Declare ( write the final answer (ex..amanda is 2, Jake is 6...)
hope this helps

Find a power series for the function, centered at c. g(x) = 4x x2 2x − 3 , c = 0
BartSMP [9]

The power series for given function g(x)=\frac{4x}{(x-1)(x+3)} is g(x)=\sum{_{n=0}^\infty}~x^n(-1+(-\frac{x}{3} )^n)

For given question,

We have been given a function g(x) = 4x / (x² + 2x - 3)

We need to find a power series for the function, centered at c, for c = 0.

First we factorize the denominator of function g(x), we have:

\Rightarrow g(x)=\frac{4x}{(x-1)(x+3)}

We can write g(x) as,

\Rightarrow g(x)=\frac{1}{x-1}+\frac{3}{x+3}\\\\\Rightarrow g(x)=\frac{-1}{1-x}+\frac{1}{1+\frac{x}{3} }\\\\\Rightarrow g(x)=\frac{-1}{1-x}+\frac{1}{1-(-\frac{x}{3} )}\\

We know that, \frac{1}{1-x}=\sum{_{n=0}^\infty}~{x^n} if |x| < 1

and \frac{1}{1-(-\frac{x}{3} )}=\sum{_{n=0}^\infty}~x^n(-\frac{x}{3} )^n  if |\frac{x}{6}| < 1

\Rightarrow g(x)=-\sum{_{n=0}^\infty}~x^n+\sum{_{n=0}^\infty}~x^n(-\frac{x}{3} )^n\\     if |x| < 1 and  if |\frac{x}{6}| < 1

\Rightarrow g(x)=\sum{_{n=0}^\infty}~x^n(-1+(-\frac{x}{3} )^n) if |x| < 1

Therefore, the power series for given function g(x)=\frac{4x}{(x-1)(x+3)} is g(x)=\sum{_{n=0}^\infty}~x^n(-1+(-\frac{x}{3} )^n)
