Step-by-step explanation:
The flat rate for renting the car = $35 per day
The amount charged as insurance fee per day for renting the car for 3 days or less = $10
The insurance fee charged per day when the car is rented for more than 3 days = $5
Let the number of days = x
Therefore, we have;
For x ≤ 3, f(x) = 35 × x + 10 × x = x × (35+10) = 45·x
For x > 3, f(x) = 35 × x + 5 × x = x × (35+5) = 40·x
Therefore;
The charge rate for renting the car for less than or equal to 3 days = 45·x
The charge rate for renting the car for more than 3 days = 40·x
The piece-wise function can be presented as follows;
Answer:
first four terms are 2, 7, 12, 17
Step-by-step explanation:
use this formula: =
+ (n - 1)· d
where 'n' equals the position in the sequence the term is in and 'd' is the common difference
if = 2 and d = 5 are given, plug those into formula
= 2
= 2 + (2 - 1)·5 = 2+5 = 7
= 2 + (3 - 1)·5 = 2+2(5) = 12
= 2+(4 - 1)·5 = 2+3(5) = 17
