Answer:
Mass = 1.3 Kilograms.
Step-by-step explanation:
Given the following data;
Force = 55.1 N
Acceleration = 41.6 m/s²
To find the mass of the stone in kg;
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Force = mass * acceleration
Substituting into the formula, we have;
55.1 = mass * 41.6

Mass = 1.3 Kilograms

Answer:
a) 
b) See Below for proper explanation
Step-by-step explanation:
a) The objective here is to Use the power series expansions for ex, sin x, cos x, and geometric series to find the first three nonzero terms in the power series expansion of the given function.
The function is 
The expansion is of
is 
The expansion of cos x is 
Therefore; ![e^x + 3 \ cos \ x = 1 + \dfrac{x}{1!}+ \dfrac{x^2}{2!}+ \dfrac{x^3}{3!} + ... 3[1 - \dfrac{x^2}{2!}+ \dfrac{x^4}{4!}- \dfrac{x^6}{6!}+ ...]](https://tex.z-dn.net/?f=e%5Ex%20%2B%203%20%5C%20cos%20%5C%20x%20%20%3D%201%20%2B%20%5Cdfrac%7Bx%7D%7B1%21%7D%2B%20%5Cdfrac%7Bx%5E2%7D%7B2%21%7D%2B%20%5Cdfrac%7Bx%5E3%7D%7B3%21%7D%20%2B%20...%203%5B1%20-%20%5Cdfrac%7Bx%5E2%7D%7B2%21%7D%2B%20%5Cdfrac%7Bx%5E4%7D%7B4%21%7D-%20%5Cdfrac%7Bx%5E6%7D%7B6%21%7D%2B%20...%5D)

Thus, the first three terms of the above series are:

b)
The series for
is 
let consider the series; 

Thus it converges for all value of x
Let also consider the series 
It also converges for all values of x
