The taylor series about x=5 for a certain function converges

ikadub [295]

The evaluation of the function $f(x)=e^x$ at a=0 and x=5 by the taylor series will have a value 65.37.

<h3>What is taylor's series?</h3>

We know the fromula of taylor series is given as:

$f(x)=f(a)+\dfrac{f'((a)}{1!}(x-a)+\dfrac{f''(a)}{2!}(x-a)^2+\dfrac{f'''(a)}{3!}(x-a)^3.................$

Now for the function $f(x)=e^x$ the taylor's series will become.

$f(x)=e^a+e^ax+\dfrac{e^ax^2}{2!}+\dfrac{e^ax^3}{3!}+\dfrac{e^ax^4}{4!}$

$f(x)=1+x+\dfrac{x^2}{2!}+\dfrac{x^3}{3!}+\dfrac{x^4}{4!}$

So at x=5 the values will become

$f(x)=1+5+12.5+20.83+26.04=65.37$

hence the evaluation of the function $f(x)=e^x$ at a=0 and x=5 by the taylor series will have a value 65.37.

Can anyone help me solve this function please?

myrzilka [38]

Answer:

f(-5) = 19

Step-by-step explanation:

f(t) = -3t+4

Let f(t) = 19

19 = -3t+4

Subtract 4 from each side

19 - 4 =-3t+4-4

15 = -3t

Divide each side by -3

15/-3 = -3t/-3

-5 = t

Playland park charges 7 dollars admission plus 75 crnts per ride. Funland park charges 12.50$ admission plus 50 cents per ride.

WINSTONCH [101]

Answer:

22 rides

Step-by-step explanation:

Both the parks has a fixed cost (admission fee) and a variable cost (per ride cost). We can model 2 equations in "x" [let x be number of rides], equate them and find "x".

<u>Playland Park:</u>

Fixed Cost = 7

Variable Cost = 0.75x (in dollars)

Equation = 7 + 0.75x

<u>Funland Park:</u>

Fixed Cost = 12.50

Variable Cost = 0.50x (in dollars)

Equation = 12.50 + 0.50x

Now we equate and solve for x:

$7+0.75x=12.50 + 0.50x\\0.75x-0.50x=12.50-7\\0.25x=5.50\\x=\frac{5.50}{0.25}\\x=22$

Hence,

the cost would be same for both parks for 22 rides
