Use the chain rule to find the derivative of each of the following : a.

b.

see explanation

Step-by-step explanation:

Using the chain rule

Given

y = f(g(x)), then

= f'(g(x)) × g'(x)

(a)

y = = 2 (

= 2. - 3 × (3x² - x + 7)

   = - 6 × (6x - 1)

   =

---------------------------------------------------

   (b)

y =

= 10 × (4x - 10)

    = 10 × 4

     = 40

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
