    yes 7250 or something so it does
    How'd you work it out? Scared to do my working on here incase I get roasted but here goes:

    ====
    Paul buys a new car for $(American computer, insert pounds)15,000

    The magazine said new cars lose over half their value after 3 years. Is this true?

    100-x% (X is the percentage depreciation after the first year, don't know value)

    X% So X/100*15,000 = x* (asterik is for future notation)

    100-x% (X is the percentage depreciation for the next years after the first, don't know value)

    X% so X/100*x*(from previous answer) = 7392 <---- the answer I got.

    Yes, the car lost over half its value as (15000/2 = 7500 so 7500-7392 = 108).

    If I have the correct numbers,This is one way of doing last Q

    Area = ( absinC)/2Sin-1 C

    = 18x2/(7x8)= 40.00520088 degrees (DO NOT ROUND)

    a^2 = b^2 + c^2 - 2 x b x c= 27.20955764 cm (DO NOT ROUND)

    Cos A^-1= (b^2 + c^2 - a^2) / 2 x b x c

    = 80.37550115

    = 80.4 degrees

    15000*0.77*0.82*0.82=7766.22

    This is the correct answer so Paul is wrong

    I didn't do a curve on the graph as it was up and down numbers if you get what I mean, rather than increasing. rip A grade I was really hoping for
