Answer:
The consecutive numbers are 62 and 63
Step-by-step explanation:
Let the larger number be represented by x and the smaller number by y,
Provided they are consecutive numbers;
--- Equation 1
From the question; we have that
--- Equation 2
Required
Find x and y
Multiply both sides of equation 2 by 14
![14 * \frac{4x}{7} = 14 * \frac{y}{2} + 14 * 5](https://tex.z-dn.net/?f=14%20%2A%20%5Cfrac%7B4x%7D%7B7%7D%20%3D%2014%20%2A%20%5Cfrac%7By%7D%7B2%7D%20%2B%2014%20%2A%205)
![2 * 4x = 7 * y + 70](https://tex.z-dn.net/?f=2%20%2A%204x%20%3D%207%20%2A%20y%20%2B%2070)
---- Equation 3
Substitute y + 1 for x in equation 2
![8(y + 1) = 7y + 70](https://tex.z-dn.net/?f=8%28y%20%2B%201%29%20%3D%207y%20%2B%2070)
Open bracket
![8y + 8 = 7y + 70](https://tex.z-dn.net/?f=8y%20%2B%208%20%3D%207y%20%2B%2070)
Collect like terms
![8y - 7y = 70 - 8](https://tex.z-dn.net/?f=8y%20-%207y%20%3D%2070%20-%208)
![y = 62](https://tex.z-dn.net/?f=y%20%3D%2062)
![x = y + 1](https://tex.z-dn.net/?f=x%20%3D%20y%20%2B%201)
So,
![x = 62 + 1](https://tex.z-dn.net/?f=x%20%3D%2062%20%2B%201)
![x = 63](https://tex.z-dn.net/?f=x%20%3D%2063)
Hence, the consecutive numbers are 62 and 63
Answer:
R3 <= 0.083
Step-by-step explanation:
f(x)=xlnx,
The derivatives are as follows:
f'(x)=1+lnx,
f"(x)=1/x,
f"'(x)=-1/x²
f^(4)(x)=2/x³
Simialrly;
f(1) = 0,
f'(1) = 1,
f"(1) = 1,
f"'(1) = -1,
f^(4)(1) = 2
As such;
T1 = f(1) + f'(1)(x-1)
T1 = 0+1(x-1)
T1 = x - 1
T2 = f(1)+f'(1)(x-1)+f"(1)/2(x-1)^2
T2 = 0+1(x-1)+1(x-1)^2
T2 = x-1+(x²-2x+1)/2
T2 = x²/2 - 1/2
T3 = f(1)+f'(1)(x-1)+f"(1)/2(x-1)^2+f"'(1)/6(x-1)^3
T3 = 0+1(x-1)+1/2(x-1)^2-1/6(x-1)^3
T3 = 1/6 (-x^3 + 6 x^2 - 3 x - 2)
Thus, T1(2) = 2 - 1
T1(2) = 1
T2 (2) = 2²/2 - 1/2
T2 (2) = 3/2
T2 (2) = 1.5
T3(2) = 1/6 (-2^3 + 6 *2^2 - 3 *2 - 2)
T3(2) = 4/3
T3(2) = 1.333
Since;
f(2) = 2 × ln(2)
f(2) = 2×0.693147 =
f(2) = 1.386294
Since;
f(2) >T3; it is significant to posit that T3 is an underestimate of f(2).
Then; we have, R3 <= | f^(4)(c)/(4!)(x-1)^4 |,
Since;
f^(4)(x)=2/x^3, we have, |f^(4)(c)| <= 2
Finally;
R3 <= |2/(4!)(2-1)^4|
R3 <= | 2 / 24× 1 |
R3 <= 1/12
R3 <= 0.083
