Answer:
y = 9 cos [(⅕pi)x]
Step-by-step explanation:
Amplitude = 9
Period = 10
2pi/10 = pi/5
Answer:
0.000025
Step-by-step explanation:
PEMDAS (Exponets first.)
10^5 = 100,000
10^10 = 10,000,000,000
rewrite
2.5 x 100,000 divided by 1.0 x 10,000,000,000
PEMDAS (multiplication next.)
2.5 x (10^5) = 250,000
1.0 x (10^10) = 10,000,000,000
rewrite.
250,000 divided by 10,000,000,000 = 0.000025
0.000025
D. 7 miles
Step-by-step explanation:
26.5/4 =6.62
So the best estimate is 7 miles
Infinitely many solutions is the answer : D
Based on your answer where ask to determined the number of outcome and decide whether the event is simple or not.
-So in event A is 4000 and a sample space
-So event B is 500 its just a number of outcome
