use the method of undetermined coefficients to set up the 5 × 5 vandermonde system that would determine a fourth-order accurate finite difference approximation to u 00(x) based on 5 equally spaced points,
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.

Eshaal is creating a model of a pyramid. The model created will need to be scaled up from the blueprint.
If segments DE and AB are parallel, which of the following expressions will help Eshaal determine the length of segment BC?
BC = CE
BC equals AC times CE all over CD
BC equals AC times DE all over CE
BC = AC
Answer:
See attachment
PS:
Can I have Brainliest?
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 a rectangle is 5 times its width if the perimeter of the rectangle is 108 yd find its length and width
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.

how many ways can 12 passengers be seated in a small airplane with 15 seats
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]

Since, M is the midpoint of XY.

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.

(h -f)(x) = x² -x +2(f +h)(x) = x² +x -2(g -f)(x) = x +5(g +h)(x) = x² +2x +3Step-by-step explanation:
Give three functions f(x), g(x), and h(x), you want various combinations of them.
Operations on functionsIf ✧ 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 ...
f(x) = x -2g(x) = 2x +3h(x) = x²(h -f)(x)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 +h)(x) = f(x) +h(x) = (x -2) +x²
(f +h)(x) = x² +x -2
(g -f)(x)(g -f)(x) = g(x) -f(x) = (2x +3) -(x -2) = 2x +3 -x +2
(g -f)(x) = x +5
(g +h)(x)(g +h)(x) = g(x) +h(x) = (2x +3) +x²
(g +h)(x) = x² +2x +3

2x
8x-5
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
ok, subtituted:
s1= x
=34 feet
s2= 8x - 5
=8(34) - 5
=272 - 5
=267 feet
s3= 2x
=2(34)

1. Find f(-4) if f(x) = -11x + 7
Answer:
x= 3/11
Step-by-step explanation:
Since you replace f(x) with 4,
4=-11x+7
-3=-11x
-3/-11=x
Answer:
51
Step-by-step explanation:
f(-4); f(x) = -11x + 7
f(x-4) = -11(-4) + 7
f(x-4) = 44 + 7
f(x-4) = 51
I basically just plugged -4 in for the value of the x's, and solved the equation.
