Differentiate S(n): To find the instantaneous rate of change, we need to differentiate the function S(n) with respect to n.S(n)=1.6⋅ln(0.9n)Let's find S′(n), the derivative of S(n).
Apply Chain Rule: Using the chain rule, the derivative of ln(0.9n) is (0.9n)1 times the derivative of 0.9n, which is 0.9. So, S′(n)=1.6×((0.9n)1)×0.9
Simplify S′(n): Simplify the expression to find S′(n).S′(n)=1.6×(0.9n0.9)
Evaluate at n=10: Cancel out the 0.9 in the numerator and denominator.S′(n)=1.6×(1/n)
Calculate S′(10): Now we need to evaluate S′(n) at n=10 to find the instantaneous rate of change when there are 10 terms.S′(10)=1.6×(101)
Final Result: Calculate the value of S′(10).S′(10)=1.6×0.1
Final Result: Calculate the value of S′(10). S′(10)=1.6×0.1S′(10)=0.16This is the instantaneous rate of change of the search length when there are 10 terms.
