Answer:
The dollar bills would encircle earth 65753.1 times
Step-by-step explanation:
We have
Length of dollar bill = 15.5 cm
Total dollar bills = 17 trillion = 
Thus the length of 17 trillion dollar bills equals
Now taking shape of earth as a perfect sphere the circumference of earth becomes
Thus the number of times the dollar bills would encircle earth equals
Answer:
A
Step-by-step explanation:
note that the exact value of
sin ( 
) = 
= 
← the value of the x- coordinate
Answer: x = 10
Step-by-step explanation: 7x10 = 70
Step-by-step explanation:
cot x + 2 tan x + tan³ x
Write in terms of sine and cosine:
(cos x / sin x) + 2 (sin x / cos x) + (sin³ x / cos³ x)
Find the common denominator:
(cos⁴ x / (sin x cos³ x) + 2 (sin² x cos² x / (sin x cos³ x)) + (sin⁴ x / (sin x cos³ x))
Add:
(cos⁴ x + 2 sin² x cos² x + sin⁴ x) / (sin x cos³ x)
Factor:
(sin² x + cos² x)² / (sin x cos³ x)
Pythagorean identity:
1 / (sin x cos³ x)
Multiply top and bottom by cos x:
cos x / (sin x cos⁴ x)
Simplify:
cot x sec⁴ x
D. there is a perfect association between the variables
