Length of the stem at time 0 is 20 cm. The arithmetic growth rate is 30 cm per day. What is the length of the stem at the end of the 7^ th day ?

Step-by-step solution

The equation for arithmetic growth is given by: L_t = L₀ + rt Where: L_t is the length at time t L₀ is the initial length at time t = 0 r is the arithmetic growth rate t is the time Given: L₀ = 20 cm r = 30 cm/day t = 7 days Substituting the given values into the equation: L₇ = 20 + 30 7 L₇ = 20 + 210 L₇ = 230 cm
