Answer:
An Irrational number is a number that cannot be expressed as the ratio of two integers.
Example: ![\pi](https://tex.z-dn.net/?f=%5Cpi)
its numbers are infinite
Cos^4(x) =
(cos²x)² =
(1-sen²x)² =
1² - 2*1*sen²x + sen^4x =
1 - 2sen²x + sen^4x
0.800 rounded to the nearest tenth is0.8
Answer:
Step-by-step explanation:
This problem is just really long- it's trying to confuse you with complicated wording. Here's it demystified:
a)
t = 0 degrees Celsius
d = 1500 meters
Find the temperature, T.
b)
d = 300 meters
T = 26 degrees Celsius
Find the ground temperature, t.
NOTE: The temperatures are different! T is the final temperature and t is the ground temperature.
final answer is x>3
