Answer:
Step-by-step explanation:
y=ar^x
(ar^5)/(ar^3)=72/432
r^2=1/6
Since r^2 < 1
This is exponential decay.
- 16:10
- 24:15
- 40:25
8:5 is just a simplier version of these other ratios
7 is 50% of 14 because 2 times 7=14 and 50 times 2=100
550,000 or 600,000
780,573 estimates to 780,000 or 800,000
229,615 estimates to 230,000 or 200,000
780,000-230,000=550,000
or
800,000-200,000=600,000
