It is d- the function is a line
Store 1 : 12 paper towels for 3.60
3.60 / 12 = 0.30......30 cents per roll
store 2 : 10 paper towels for 3.50
3.50/10 = 0.35....35 cents per roll
the better deal is store 1 with paper towels costing 30 cents per roll
Answer:
g(n) = -29×(-4)ⁿ⁻¹
Step-by-step explanation:
This the recursive formula of a sequence g :
g(1)=-29
g(n)=g(n-1)x(-4)
now ,we want to deduce the standard explicit formula of that sequence
It’s clear from the recursive formula (above) that :
_The common ratio = -4
_the first term = -29
Then
the standard explicit formula is : g(n) = -29×(-4)ⁿ⁻¹
