-4 - 1 = -5 can be an equation that equals -5.
Answer:
Step-by-step explanation:
The submarine now started at 750ms below sea level. If it rose 50 meters per hour period. And after 4 hours It will go to 200ms up. (50×4=200meters.) so, after 4hours it will be 750-200=550meters below the sea level.
This can be solved by the distance formula.
If the center of the circle is at (h,k)
r² = (h - 0)² + (k - 0)²
r² = (h - 6)² + (k - 0)²
r² = (h - 6)² + (k - 4)²
Equating the equations
h² + k² = (h - 6)² + k²
h = 3
(h - 6)² + k² = (h - 6)² + (k - 4)²
k = 2
Therefore, the center of the circle is at (3,2).
The answer is i√167.5 i know because i looked it up on the web
i apologize if it is wrong.
