Answer with Step-by-step explanation:

f(1) = 160 and f(n + 1) = –2f(n)

⇒ f(2)= -2×f(1)

        = -2×160

       = -320

⇒ f(3)= -2×f(2)

    = -2×(-320)

   = 640

⇒ f(4)= -2×f(3)

    = -2×640

   = -1280

Hence, Value of f(4) is:

- 1280

You buy 11 bagels with a 20$ bill how m if change do you receive? how many bagels could you buy?
Svetllana [295]
Change you’ll receive is = 0.09
you can only buy 11 because if you divide 20/11 it will give you 1.81 and if you multiply 11x 1.81 it will give you 19.91 which is close to $20 & that’s the most you can buy .
