Answer:
The answer to your question is ∠Z = 119°
Step-by-step explanation:
Data
∠W = 41°
∠Y = 81°
∠Z = ∠X = ?
Process
To solve this problem use the law that states that the sum of the internal angles in a quadrangle equals 360°.
1)
∠W + ∠Y∠ + ∠X + ∠Z = 360°
2.- Simplify
∠W + ∠Y + 2∠Z = 360
3.- Substitution
41° + 81° + 2∠Z = 360
4.- Solve for Z
2∠Z = 360 - 41 - 81
2∠Z = 238
∠Z = 238/2
∠Z = 119°

Answer:
Step-by-step explanation:
This is because 4 ft x 8 ft = 24 feet
24 feet times 12 (this is because there 12 inches in a foot)
288 inches
The slope-intercept of the line is
y= -2/3x + 2
Going up 2, left 3
Change in y

Step-by-step explanation:
One way to approximate the derivative at a point is by finding the slope of the secant line between points on either side. That is what is done in the attached spreadsheet.
f'(0.1) ≈ (f(0.2) -f(0.0))/(0.2 -0.0) = -5 . . . for example

Another way to approximate the derivative is to write a polynomial function that goes through the points (all, or some subset around the point of interest), and use the derivative of that polynomial function.
These points are reasonably approximated by a cubic polynomial. The derivative of that polynomial at the points of interest is given in the table in the second attachment. (f1 is a rounding of the derivative function f')
