7^2 = 6^2 + 9^2 - 2(6)(9)cos(m)
-68 = 2(6)(9)cos(m)
cos(m) = -0.6296
m = arcos ( -0.6296)
m = 129.0 degrees
For this case we have the following functions:
m (x)
p (x)
Where,
x: independent variable
m, p: dependent variables
For the value of x = 7 we have:
m (7)
p (7)
For this case it is true that:
m (7) = p (7)
Therefore, both functions have the same output argument for the same input value.
Answer:
C) Both m (x) and p (x) have the same output value at x = 7.
