Answer:
(a) f⁻¹(x) = 2x - 8
(b) f⁻¹(4) = 0
Step-by-step explanation:
This is usually not too difficult if you write the equation as y = f(x), then swap x and y and solve for y.
... y = (1/2)x + 4 . . . . y = f(x)
... x = (1/2)y + 4 . . . . variables swapped
... x - 4 = (1/2)y . . . . . subtract 4
... 2(x -4) = y . . . . . . multiply by 2
... y = 2x - 8 . . . . . . simplify
... f⁻¹(x) = 2x -8
____
Evaluating this for x=4, we get
... f⁻¹(4) = 2·4 - 8 = 0
Answer:
The average weight of three apples = 118 g
Estimated average weight of 36 apples = 1416 g or 1 kg 416 g
Total weight of 36 apples = 50976 g or 50 kg 976 g
Sin x is possitive in two quadrants :
quadrant I and quadrant II
in quadrant I, cos x is positive
in quadrant II , cos x is negative
so i think the answer is : quadrant II
