The fourth-order accurate finite difference approximation is:

u00(x) = c−2u(x − 2h) + c−1u(x − h) + c0u(x) + c1u(x + h) + c2u(x + 2h) + O(h4).

Compute the coefficients using the matlab code fdstencil.m and check that they satisfy the system you determined in part (a).

Test this finite difference formula to approximate u

00(1) for u(x) = sin(2x) with values of h from the array hvals = log space(-1, -4, 13). Make a table of the error vs. h for several values of h and compare against the predicted error from the leading term of the expression printed by  fdstencils.

You should observe the predicted accuracy for larger values of h. For smaller values, numerical cancellation in computing the linear combination of u values impacts the accuracy observed.

Answer:

Step-by-step explanation:

Give three functions f(x), g(x), and h(x), you want various combinations of them.

If ✧ represents some generic math operator, we often use the notation ...

  (f ✧ g)(x)

as a shorthand way to write ...

  f(x) ✧ g(x)

The usual meaning of the operator applies.

The three given functions are ...

The definitions are substituted for the function name:

  (h -f)(x) = h(x) -f(x) = x² -(x -2)

  (h -f)(x) = x² -x +2

  (f +h)(x) = f(x) +h(x) = (x -2) +x²

  (f +h)(x) = x² +x -2

  (g -f)(x) = g(x) -f(x) = (2x +3) -(x -2) = 2x +3 -x +2

  (g -f)(x) = x +5

  (g +h)(x) = g(x) +h(x) = (2x +3) +x²

  (g +h)(x) = x² +2x +3

Answer:

Step-by-step explanation:

The cost when no sugar is transported is 3250, so that is the "y-intercept". (There is no "y". The vertical axis is labeled "c", so that  is the c-intercept.)

The cost per ton is 125, so that is the slope or "rate of change". Each increase of 1 unit in the value of "s" will result in an increase of 125 in the value of "c". The grid lines for "c" are 500 apart, so 1 vertical grid space will correspond to 500/125 = 4 horizontal grid spaces.

The graph starts at the left side halfway between 3000 and 3500. It goes up 1 grid square for each 4 grid squares to the right.

The correct statement is  BC equals to AC times CE all over CD.

We have, If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally. this is known as the triangle proportionality theorem.

Given, DE and AB are parallel

So,   [tex]\frac{BC}{CE} =\frac{AC}{CD}[/tex]

[tex]BC = \frac{AC\times CE}{CD}[/tex]

Therefore in statement form we say that BC equals to AC times CE all over CD.

The length of the rectangle is 45 yd,

and the width of the rectangle is 9 yd.

Given that, The length of a rectangle is 5 times its width, and

the perimeter  is 108 yd.

Let the width of rectangle be 'x' yd ,

therefore the length of the rectangle is '5x' yd  as mentioned that the length is five times the width.

we know that,

Perimeter of the rectangle = 2(length + width)

and given perimeter of rectangle is 108 yd.

Therefore the perimeter = 2( 5x + x )

                               108    = 2( 6x )

                               108    = 12x

                          108/12    = x

                                x      = 9

we know that 'x' is nothing but the width of the given rectangle.

Therefore the width of given rectangle is 9 yd, and

The length of the given rectangle is 5x = 5 * 9 = 45 yd.

Answer:

^two dimentional figure with algebra^

the perimwter from triangle is:

s1 + s2 + s3

ok, enter:

s1 + s2 + s3= 369

x + (8x -5) + 2x = 369

x + 8x - 5 + 2x = 369

group according to the same variable

(x + 8x + 2x) + (-5)=369

11x + (-5)=369

11x - 5= 369

11x = 369 + 5

11x =374

x =374 : 11

x = 34

Step-by-step explanation:

f(-4); f(x) = -11x + 7

f(x-4) = -11(-4) + 7

Answer:

455

Step-by-step explanation:

This is a combinatorics problem.

It is asking  us the number of ways a sample of r elements can be obtained from a larger set of n objects where order does not matter and repetitions are not allowed

It is called n choose k and the formula is

[tex]C(n,r) = \binom{n}{r} = \frac{n!}{( r! (n - r)! )}[/tex]

Here the ! symbol represents the factorial of that number

For example,

[tex]n! = n\cdot(n-1)\cdot(n-2)......\cdot3\cdot2\cdot 1[/tex]

Here n = 15 and r = 12

How many ways can we arrange 12 people in 15 slots

[tex]C(n,r) = C(15,12)[/tex]

[tex]= \frac{15!}{( 12! (15 - 12)! )}[/tex]

[tex]= \frac{15!}{12! \times 3! }[/tex]

[tex]= 455[/tex]

You can use a calculator to do this but noting that

15! = 15 x 14 x 13 x 12! and 3! = 3 x 2 = 6 we get

[tex]= \frac{15!}{12! \times 3! } = \frac{15\cdot14\cdot13}{6} = 455[/tex]
