Given two measurements, x and y, which both have uncertainty. Use the general error propagation formula, δf = vuut ∂f ∂xδx!2 + ∂

f ∂y δy!2 to derive the error propagation formulas, i.e. the expression for δf, for the following specific cases as found in the Taylor textbook. (a) Scaling by a constant: f = Cx where C is a constant with no uncertainty. (b) Addition: f = x + y (c) Multiplication: f = xy (d) Division: f = x y

A carpenter had two pieces of lumber that totaled 55 feet in length. The shorter piece was 12 feet
dimulka [17.4K]

The equation to find the length of the longer piece is

x- 12 = 55

Step-by-step explanation:

  • A carpenter had two pieces of lumber that totaled in length = 55 feet
  • The shorter piece than the longer piece has length of which is = 12 feet
  • The longer piece is denoted as= x
  • Find x = ?
  • The equation can be formed to find the value of x as,
  • Longer piece (x) ₋ shorter piece (12) = total length (55)
  • Therefore, x ₋ 12 = 55
  • the above equation states that
  • if you subtract the shorter piece from the total length of the you will get the length of the longer piece.
  • therefore,
  • if you shift the value of shorter length on the right hand side, you can find the value of x
  • so, x= 55 ₋ 12
  • value of x = 43
  • therefore, the length of the longer piece is 43 feet long.

Given that the points (-1,6). (3,6), (3, 1), and (-1, 1) are vertices of a rectangle, how much shorter is the width than the len
Ksju [112]
Since the given coordinates are already in order,
then and two consecutive distances between the coordinates will give length and breadth,

Using distance formula,
\sqrt{ {( - 1 - 3)}^{2}  +  {(6 - 6)}^{2} }  \\  =  \sqrt{ { (- 4)}^{2} }  \\  =  \sqrt{16 }  \\  = 4
(we'll not consider the negative value since distances can't be negative)

Applying this again on 2nd and 3rd coordinates,
\sqrt{ {(3 - 3)}^{2} +  {(6 - 1)}^{2}  }  \\  =  \sqrt{ {5}^{2} }  \\  = 5
(we'll not consider the negative value since distances can't be negative)

Since length's always gotta be greater than bredth
therefore,
the difference will be 5-4= 1 units


Hence width is 1 unit shorter than length.



Note: Unit used is "unit/s"

If f(x) = 5x - 3 and g(x) = 2x + 9, determine<br> f(g(4)
Over [174]

Answer:

82

Step-by-step explanation:

f(x) = 5x - 3

g(x) = 2x + 9

f(g(x)) = 5 (2x + 9) - 3 ..... replace x with g(x)

f(g(4)) = 5 * (2 * 4 + 9) -3 = 85 - 3 = 82
