The width of the walkway is 3 feet, If the area of the garden is 484 feet^{2} and the area covered by both the garden and the walkway (the entire square) is 784 feet^{2}.

Step-by-step explanation:

The given is,

                 Area of the garden is 484 feet^{2}

                 Area covered by both the garden and the walkway (the entire square) is 784 feet^{2}.

                Let, x - Width of the walkway

Step:1

                Formula to calculate area of square is,

                                A= a^{2}...........................(1)

                Where, r - Radius of square

Step:2

               For garden,

               A = 484 feet^{2}

               Equation (1) becomes,

                            484=a^{2}

               Take square root on both sides,

                               a=\sqrt{484}

                                a = 22 feet

               For garden and the walkway (the entire square),

               A = 784 feet^{2}

               Equation (1) becomes,

                            784=a^{2}

               Take square root on both sides,

                               a=\sqrt{784}

                                a = 28 feet

Step:3

                  Ref attachment,

                  Side of garden and the walkway =

                             Side of garden + 2 (width of the walkaway)....(1)

                                                 28 = 22 + 2 ( x )

                                             2 ( x ) =   28 - 22

                                                       = 6

                                                    x = \frac{6}{2}

                                        Width, x = 3 feet

Result:

          The width of the walkway is 3 feet, If the area of the garden is 484 feet^{2} and the area covered by both the garden and the walkway (the entire square) is 784 feet^{2}.

Consider the function f(x)=xln(x). Let Tn be the nth degree Taylor approximation of f(2) about x=1. Find: T1, T2, T3. find |R3|
Fynjy0 [20]

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
