Answer: 2years, 5 months

Step-by-step explanation:

Principal, P = $6000

Rate, R = 3%

Interest, I = $450

Time, T =?

Simple Interest, I = P x T x R/ 100

making T, subject of formula

T = 100 x I/ P x T

Substituting the values into the equation,

T = 100 x 450/ 6000 x 3

T = 45000/ 18000

T = 2.5years = 2years, 5 months

Answer:

0.0032

Step-by-step explanation:

We need to compute $e^{0.4}$ by the help of third-degree Taylor polynomial that is expanded around at x = 0.

Given :

$e^{0.4}$ < e < 3

Therefore, the Taylor's Error Bound formula is given by :

$|\text{Error}| \leq \frac{M}{(N+1)!} |x-a|^{N+1}$ , where $M=|F^{N+1}(x)|$

$\leq \frac{3}{(3+1)!} |-0.4|^4$

$\leq \frac{3}{24} \times (0.4)^4$

$\leq 0.0032$

Therefore, |Error| ≤ 0.0032
