Answer:
Step-by-step explanation:
(-1/9) /(1/3) = (1/3)/(-1) = -1/3....the common ratio of geometric sequence
the recursive rule is :
the nth term is : An =A1 × r^(n-1)
r : the common ratio
A1 ; the first term
r = -1/3 and A1 = 3
An =3 ×(-1/3)^(n-1)
Answer:
700 miles driven in a day
Step-by-step explanation:
Create an equation to represent the situation, where x is the number of miles.
0.8x + 120 = 0.9x + 50
Solve for x:
120 = 0.1x + 50
70 = 0.1x
700 = x
So, the rental costs will be the same at 700 miles driven in a day.
