Answer:
The magnitude of the given vector is 40.72 units.
Step-by-step explanation:
The given vector is
We know that for any vector 'r' the magnitude is given by
Comparing with the given vector we have
x = -3
y = 40
z = 7
Thus the magnitude equals
Answer: (g-f)(x)=-4x
Explanation: According to the graph, line created by function f(x) passes through the points (1,-3) and (0,0) and similarly, line created by the function passes through the points (1,1) and (0,0).
Thus, we can find the equation of the lines with help of formula ×
so, equation of line created by function f(x)
y+3=×(x-1)
y+3=×(x-1)
y+3=-3x+3
y=-3x thus function f(x)=-3x
similarly, equation of line created by function g(x)
y=x thus function g(x)=x
Now, we have to find out, (g-f) (x)= g(x)-f(x)= -3x-x= -4x
