To find the cost of one slice 12.37/5= 2.47 per slice.

so y= 2.47p+1.12

Jim bought a fishing rod for $42. This price was 70% of the original price. What was the original price?

ankoles [38]

So if $42 was 70% of the original price that means you saved 30% so work out 30% of $42 then add it to the $42 = $12.60 + $42

Find a power series representation for the function. (give your power series representation centered at x = 0. ) f(x) = ln(5 − x

klio [65]

Recall that for $|x|$ , we have the convergent geometric series

$\displaystyle \sum_{n=0}^\infty x^n = \frac1{1-x}$

Now, for $\left|\frac x5\right| < 1$ , we have

$\dfrac1{5 - x} = \dfrac15 \cdot \dfrac1{1 - \frac x5} = \dfrac15 \displaystyle \sum_{n=0}^\infty \left(\frac x5\right)^n = \sum_{n=0}^\infty \frac{x^n}{5^{n+1}}$

Integrating both sides gives

$\displaystyle \int \frac{dx}{5-x} = C + \int \sum_{n=0}^\infty \frac{x^n}{5^{n+1}} \, dx$

$\displaystyle -\ln(5-x) = C + \sum_{n=0}^\infty \frac{x^{n+1}}{5^{n+1}(n+1)}$

If we let $x=0$ , the sum on the right side drops out and we're left with $C=-\ln(5)$ .

It follows that

$\displaystyle \ln(5-x) = \ln(5) - \sum_{n=0}^\infty \frac{x^{n+1}}{5^{n+1}(n+1)}$

$\displaystyle \ln(5-x) = \boxed{\ln(5) - \sum_{n=1}^\infty \frac{x^n}{5^n n}}$

I know that 300 divided by 30 equals 10 because the3 in 300 represents?

STALIN [3.7K]

No , 100 * 3 = 300 that is the correct way
