Answer:
if x=1 y=-2x1
Step-by-step explanation:
This works just like exponential decay...
final=initial(rate^time)...
f=600(1-.29)^5
f(5)=108.25
Answer:
18
Step-by-step explanation:
This question is essentially asking what the greatest common factor of 72 and 90 is. The prime factorization of 72 is:
![2^3\cdot 3^2](https://tex.z-dn.net/?f=2%5E3%5Ccdot%203%5E2)
For 90:
![2\cdot 5\cdot 3^2](https://tex.z-dn.net/?f=2%5Ccdot%205%5Ccdot%203%5E2)
Therefore, the greatest common factor is
. Hope this helps!
