Trina is closer to the ocean because she is only 85.6 meters away from the surface, while Jessie is 87.9 meters away. 85.6 is less than 87.9, which means that Trina is closer.
Step-by-step explanation:
Sea level is represented by the number 0. -85.6 is closer to the number 0 than 87.9 is, which tells us that Trina is closer.
Hope this helps :)
Answer:
k = 4 + 5.10i , 4 - 5.10i
Step-by-step explanation:
8k - k^2 = 42
k^2 - 8k + 42 = 0
Completing the square:-
(k - 4)^2 - 16 +42 = 0
(k - 4)^2 = -26
k- 4 = +/-sqrt26
k = 4 + sqrt26 or 4 - sqrt26
k = 4 + 5.10i , 4 - 5.10i
