2.4 - 2.6 - using - differentiation - rules: problem (1 point) results for this submission 2 of the answers are not correct. compute the derivative of the given function in two different ways. h(s)=(3s - 10)(2s + 4) a. use the product rule fg=f·g+f·g. (fill in each blank, then simplify.) h(s)=(3s - 10)·(2)+(3)·(2s + 4)=12s - 1: b. use algebra first to simplify h, then differentiate without the product rule. h(s)=6s - 4 note: you can earn partial credit on this problem. preview my answers submit answers your score was recorded. your score was successfully sent to canvas. you have attempted this problem 4 times. you received a score of 40% for this attempt. your overall recorded score is 40%. you have unlimited attempts remaining.
Answer
Explanation:
Step1: Apply product - rule
Let (f(s)=3s - 10), (g(s)=2s + 4). Then (f'(s)=3) and (g'(s)=2). By the product - rule ((fg)'(s)=f(s)g'(s)+f'(s)g(s)), so (h'(s)=(3s - 10)\times2+3\times(2s + 4)).
Step2: Simplify the product - rule result
[ \begin{align*} h'(s)&=(3s - 10)\times2+3\times(2s + 4)\ &=6s-20 + 6s+12\ &=12s - 8 \end{align*} ]
Step3: Simplify (h(s)) first
Expand (h(s)=(3s - 10)(2s + 4)=6s^{2}+12s-20s - 40=6s^{2}-8s - 40).
Step4: Differentiate the expanded (h(s))
Using the power - rule ((x^n)'=nx^{n - 1}), (h'(s)=(6s^{2}-8s - 40)'=12s-8).
Answer:
a. (h'(s)=(3s - 10)\cdot(2)+(3)\cdot(2s + 4)=12s - 8) b. First expand (h(s)=6s^{2}-8s - 40), then (h'(s)=12s - 8)
