正确公式为 **FV = PV * (1 + r)^n**(选项A),它表示现值以复利增长。 - **选项A**:正确。复利公式体现本金与利息的累积,逐项确认符合财务原理。 - **选项B**:错误。此公式用于计算现值(PV),是将未来价值折现到当前。 - **选项C**:错误。使用减法而非加法,会导致价值减少,与实际增长逻辑相反。
Step 1: Determine the total distance traveled Note that if the problem mentions a round journey, it means that the same distance is covered twice. Step 2:Measure or determine the time taken to cover the distance Step 3:Use the formula for speed ...
What is the formula for measuring the price elasticity of supply? If P=200-4Q, then the price elasticity of demand at P=80 is what? How do you calculate the elasticity of demand between prices? How is the price elasticity of demand measured?
Speed and velocity are distinct concepts; while speed only considers the magnitude of movement, velocity also takes into account the direction. The formula for velocity is given by velocity (v)=displacement (d)time (t)velocity (v)=time (t)displacement (d), where displacement is the distan...
