Last year, there were b pies baked for the bake sale. This year, there were 158 pies baked. Using b, write an expression for the

<h3>Answer: b+158</h3>

We simply add the two subtotals to get the grand total. If we knew the value of b, then we'd be able to find an actual numeric result.

For example, let's say b = 100 pies were baked last year. That would mean b+158 = 100+158 = 258 pies were made over the two year period. However, since we don't know what b is, we just leave b+158 as is.

Find the taylor polynomial t3(x) for the function f centered at the number

olga nikolaevna [1]

$e^{-4x}=\displaystyle\sum_{n=0}^\infty\frac{(-4x)^n}{n!}=1+(-4x)+\dfrac{(-4x)^2}2+\dfrac{(-4x)^3}6+\cdots$
$e^{-4x}=1-4x+8x^2-\dfrac{32x^3}3+\cdots$

$\sin2x=\displaystyle\sum_{n=0}^{\infty}\frac{(-1)^k(2x)^{2k+1}}{(2k+1)!}=(2x)-\dfrac{(2x)^3}6+\cdots$
$\sin2x=2x-\dfrac{4x^3}3+\cdots$

$e^{-4x}\sin2x=\left(1-4x+8x^2-\dfrac{32x^3}3+\cdots\right)\left(2x-\dfrac{4x^3}3+\cdots\right)$
$e^{-4x}\sin2x=2x-8x^2+\dfrac{44x^3}3+\cdots$

$\implies T_3(x)=2x-8x^2+\dfrac{44x^3}3$
