25. yes it's direct variation
26. yes
Answer:
A = Π R^2 = 3.14 * 6^2 m = 113 m^2 area of entire circle
102/360 = a = area of sector
a = 102/360 * 113 m^2 = 32 .0 m^2
Proof:
Given any functions they are linearly dependent if we can find values of such that
Using the given functions in the above equation we get
This will be satisfied if and only if
Solving the equations we get
Since we have 3 variables and 2 equations thus we will get many solutions
one being if we put we get
Thus we have as one solution. Hence the given functions are linearly dependent.
