Answer:
£1638.40
Step-by-step explanation:
Step one:
Given data
A car costs £5000 when new
Each year the value decreases by 20%.
Step two:
let us compute the worth in the next 5 years
year 1
worth= 5000- 0.2*5000
worth= 5000-1000
worth= £4000
year 2
worth= 4000- 0.2*4000
worth= 4000-800
worth= £3200
year 3
worth= 3200- 0.2*3200
worth= 3200-640
worth= £2560
year 4
worth= 2560- 0.2*2560
worth= 2560-512
worth= £2048
year 5
worth= 2048- 0.2*2048
worth= 2048-409.6
worth= £1638.40
The person is wrong because after 5 years the car is worth £1638.40
17 because a constant term a quantity having a fixed value that does not. change or vary, such as a number.
9+3x^2
It's technically already in simplest form, except you usually put x first
=3x^2+9
Well you just say 35 divided by 7 and you get 5
Cause 5 times 7 is 35
Whenever we have a negative exponent, that means that the function should be in the denomenator. then the exponent will be positive.
Example
16^-4 = 1/(16^4)
