The graph does not support his claim. The vertical scale does not start At 0 which distorts the percent of change.
Step-by-step explanation:
1 garm = $50.04
7.5 gram = 50.04 × 7.5 = $375.3
₤ 152352
depreciation factor = 100 - 8 = 92% = 0.92
current value = ₤ 180000 × (0.92)² = ₤ 152352
I = sqrt(-1)
i^2 = -1
(-i)^2 = (-i)(-i) = i^2 = -1
(-i)^3 = (-i)(-i)(-i) = (-i)(i^2) = i
use these facts to find which equation is correct if x = -i
i bet on 2,3 or 4
