Length of a plant root at time 0 is 25 cm. The arithmetic growth rate is 15 cm per day. What will be the length of the root at the end of the 10th day?

Step-by-step solution

In arithmetic growth, length increases at a constant rate. Final length = initial length + (growth rate × number of days) = 25 + (15 × 10) = 25 + 150 = 175 cm . Hence the length of the root at the end of the 10th day is 175 cm.
