Answer:
y=1x or just y=x might be a good line of best fit for this data
Answer:
sin(2x)/cos x = 2sin x*cos x/ cos x = 2 sin x = 2
sin x = 1
x = pi/2
but cos pi/2 = 0
so the given equation is indeterminate for x = pi/2
Step-by-step explanation:
Answer:
D) 3 X 10⁷
Step-by-step explanation:
<u>Estimated days:</u>
- Jan 2000 to June 2001 = 1.5 years = 365*1.5 days ≈ 548 days
- 1 day = 24 hours = 24*60 minutes = 24*60*60 seconds =
- 548 days = 548 * 86400 seconds =
Best estimate is D) 3 X 10⁷
