Answer:
Option b is correct.
The series 20-15+10-5....is Divergent
Step-by-step explanation:
Alternating series Test:
satisfies:
Then the series converges,
otherwise diverges.
Given the series: 20-15+10-5....
This is a alternating series:
using the alternating series test;
for all n
⇒ the series diverges.
therefore, the given series i,e 20-15+10-5.... is divergent.
Answer:
The car will be worth £2516.22 in 5 years
Step-by-step explanation:
The rule of depreciating is
, where
∵ Dan buys a car for £2700
∴ <em>P</em> = 2700
∵ It depreciates at a rate of 1.4% per year
∴ <em>r</em> = 1.4% = 1.4/100 = 0.014
∵ We need to find how much it will be worth in 5 years
∴ <em>t</em> = 5
→ Substitute all of these values in the rule above to find A
∵
→ Use your calculator to find the answer
∴ <em>A</em> = 2516.22
∴ The car will be worth £2516.22 in 5 years
