Math sucks. Yes Ik your upset that I didn’t answer correctly-but technically I did Bc math DOES SUCK

Enter the coefficients of the fifth Taylor polynomial T5(x) for the function f(x) = x5−3x4+2x2+5x−2 based at b=1. T5(x)= + (x−1)

DENIUS [597]

Compute the necessary values/derivatives of $f(x)$ at $x=1$ :

$f(1)=3$

$f'(1)=2$

$f''(1)=-12$

$f'''(1)=-12$

$f^{(4)}(1)=48$

$f^{(5)}(1)=120$

Taylor's theorem then says we can "approximate" (in quotes because the Taylor polynomial for a polynomial is another, exact polynomial) $f(x)$ at $x=1$ by

$T_5(x)=\dfrac3{0!}+\dfrac2{1!}(x-1)-\dfrac{12}{2!}(x-1)^2-\dfrac{12}{3!}(x-1)^3+\dfrac{48}{4!}(x-1)^4+\dfrac{120}{5!}(x-1)^5$

$T_5(x)=3+2(x-1)-6(x-1)^2-2(x-1)^3+2(x-1)^4+(x-1)^5$

Another way of doing this would be to solve for the coefficients $a,b,c,d,e,g$ in

$f(x)=a+b(x-1)+c(x-1)^2+d(x-1)^3+e(x-1)^4+g(x-1)^5$

by expanding the right hand side and matching up terms with the same power of $x$ .

Help i dont ge it show work how do you solve it,???

fiasKO [112]

Okay so she had 67 homework problems and she only finished 25
she has 7 pages to complete and on each page the same number of problems

So we can use subtraction and division

(67 - 25) : 7 =
42 : 7 =
6
So there are 6 problems on each page :)

The distance between my house and the school is 25 miles and it takes 10min by bus. How fast is the bus traveling?

Vlad1618 [11]

Answer:

2.5 miles per minute

Step-by-step explanation:

speed = distance ÷ time

speed = s

distance = 25 miles

time = 10 minutes

s = 25÷10

s = 2.5 miles per minute
