Answer:
(x,y) = (4,3)
Step-by-step explanation:
The highest power of 12 that divides 273 (with remainder) is
, and dividing gives
Divide the remainder term by the next highest power of 12,
.
So
, since
The solution is: 252. 14x18
An exponential decay function is:
f=ir^t, f=final amount, i=initial amount, r=common ratio, t=number of times ratio is applied...We can see the initial value is 17000 so all we really have to find is the common ratio, or "rate" as some call it :P If we look at the second point, when t=1 we can see:
14280=17000r
r=357/425
r=0.84
So in five years the SUV will be worth more than the car by:
17000(0.84^5)-12000(0.89^5)
$408.73 (to the nearest cent)
1 2/3 * 7/8...turn the mixed number to an improper fraction
5/3 * 7/8 = 35/24 = 1 11/24
