We first need dy/dx.
dy/dx = -2sin(x/2)(1/2)
dy/dx = -sin(x/2)
We now find d^2y/dx^2.
d^2y/dx^2 = -cos(x/2)(1/2)
d^2y/dx^2 = -(1/2)cos(x/2)
Answer:
140 degrees
Step-by-step explanation:
50 = EI - LJ
160 = 1/2 EI + LJ
210 = 1.5 EI
EI = 140
Answer:
The area of the floor space is equal to 5.83 sq yards.
Step-by-step explanation:
Given that,
Each row requires a section of floor that is 1 ¾ yards by 3 ⅓ yards.
We need to find how many square yards of floor space are taken up by one row of cheerleaders.
We know that, the area of a rectangle is given by :
A = lb
So,
So, the area of the floor space is equal to 5.83 sq yards.
There are 22 lines the same amount of sides
For AB to be parallel to DC based on the diagram, angle AWZ must be equal to angle WZY.
But in the diagram shown, angle AWZ is equal to angle XYC and we are not told that WZ is parallel to XY.
Therefore his error is that he misapplied the alternate angle property.
