I think the respiratory system and circulatory system
Answer:
The distance between them is changing at the speed of 10.16 m/hr
Explanation:
Consider the sketch attached below.
The question is simply asking to calculate the resultant of the two velocities.
To get the angle between them, we simply use the coordinates of the two vectors to determine the angle between them.
90 + 45 = 135°
from the cosine rule we have
=
+
- 2abcosθ
=
+
- 2 ×6×5×cos 135
= 103.426
c = 
c = 10.17 m/hr
The reason why the electricity could decrease is because the population of the town’s people has gone down causing the electricity rate to decrease. Hope this helps you.
Answer:
Reusing
