Answer:

Step-by-step explanation:
To solve the problem, you must expand the trigonometric expression using the information given.

Answer:
There are two answers, firstly 1*125. Then, factoring 125 as a product of primes, you get 5^3. The only two numbers you can get out of 5^3 other than 125 are 5^1 = 5 and 5^2 = 25. So there's your other answer: 5*25.
Answer:
£7899
Step-by-step explanation:
Since the original price of the car is £8999 and £1100 is being given off in form of discount
So to determine the amount the car is being sold it will be
Original price - discount
8999-1100
7899
So the car is sold at £7899
Exponential model is y=Ae^(kt)
Assume initial start is 2005, time = 0, so y = 18000e^(kt)
45000 = 18000*e^(k5)
solve for k, approx 0.1832
y = 18000*e^(1.832) = 112,435, approximately
