Consider the right angles triangle with hypotenuse 15 and leg 8 cm formed by drawing the diagonal.
The other leg (x) will be the other side of the rectangle and , by Pythagoras we have:-
15^2 = 8^2 + x^2
x^2 = 225 - 64
x^2 = 161
x = 12.69 cms
So the perimeter p = 2*8 + 2* 12.69
= 16 + 25.38
= 41.38 cms (answer)
If this can be modelled by exponential decay, therefore
the function must be in the form of:
A = Ao (1 + r)^t
where A is the final value, Ao is the initial = 15000, r
is the rate of decay = -0.0015, t is time = 2010 – 1990 = 20
A = 15,000 (1 – 0.0015)^20
A = $14,556.36
520 is the principal, 156 is the total interest in 5 years. Divide the 156 by 5, and you get $31.20 per year. divide: 31.2 / 520 = 0.06. convert that to a fraction, and you get the answer: 6%
6.75*5=33.75
39.50-33.75
5.75/0.25
