Solve this with me plz plz plz plz

Ulleksa [173]

Answer:

5b+1c=3b+5c

Step-by-step explanation:

Let's use the variable c for the circles and b for the boxes.

The weights are the same on both sides, so count the boxes and circles on each side.

There are 5 boxes and 1 circle on the left side. The left side of the equation says 5b+1c.

There are 3 boxes and 5 circles on the right side. The right side of the equation says 3b+5c.

And since the 2 sides are equal, you split the 2 sides of the equation with =.

5b+1c=3b+5c

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

.please explain steps

hammer [34]

If you're using log:
Swap both sides: 1100 · 1.7^n = 7000
Divide both sides by 1100: 1.7^n = 70/11
Concert decimal to a fraction: (17/10)^n = 70/10
Take the log of both sides. (Put 17/10 into the subscript of log like the picture shows)
The answer is the decimal.
