. Neve is examining a tree limb. She notices that the smaller branches spiral away from the larger limb. The limb has 1 branch,
mash [69]

Answer:

a_1=2\\a_n=a_{n-1}+(n-1)\,,n>1

Step-by-step explanation:

Given: The smaller branches spiral in the pattern \{2,3,5,8,...\} from a larger limb.

To model: the tree growth with the Fibonacci sequence

Solution:

Take a_1=2

Let a_n denotes the n^{th} term.

a_2=3=2+1=2+(2-1)=a_1+(2-1)\\a_3=5=3+2=3+(3-1)=a_2+(3-1)\\a_4=8=5+3=5+(4-1)=a_3+(4-1)

So,

a_1=2\\a_n=a_{n-1}+(n-1)\,,n>1

Melody want to sell bags of mixed candy at her lemonade stand . She will mix chocolates pieces that cost $4.89 per bag with pean
Alja [10]

Answer:

Bags of chocolates pieces = 10 bags

Bags of peanut butter pieces = 15 bags

Step-by-step explanation:

The ratio of chocolate pieces to peanut butter pieces

($4.23-$ 3.79) : ($ 4.89 - $4.23)

= $0.44 : $0.66

=  2 : 3

Therefore; the fraction of chocolate pieces bag = 2/5

Thus; Number of bags of chocolate pieces = 2./5 × 25

                                                                        = 10 bags

Fraction of peanut pieces bags = 3/5

Therefore; Number of bags of peanut butter pieces = 3/5 × 25

                                                                                      = 15 bags
