Answer:
2am
Step-by-step explanation:
We know that the temperature variation is depicted by trignometric function. The total cycle of any trignometric function can be divded into four parts. In first quarter of the cycle, the value rises from mean to max. In 2nd quater, it falls to mean again. In third quarter it lowers to minimum and in last quarter rises to mean again.
Dividing the daily temperature variation cycle into four quaters of 6 hours each. The difference in time for any trignometric function to reach from its maximum value to minimum value is one-half of the cycle. In this case, it will be 12 hours.
Therefore daily temperature will fall to its minimum value 12 hours after reaching maximum that is at 2 am
Answer:
Perpendicular
Step-by-step explanation:
Given points P=(2,6) and Q=(4,5)
The line RS is y=2x-3.
Now we know that the line joining any two points (x1,y1) and (x2,y2) has slope m=
Now the slope of the line PQ is
m1=
= -
We know that the slope of the line in the form y=mx+c is m
So the line RS has slope m2=2
Now two lines are parallel if m1=m2
And those two lines are perpendicular if 
here m1= - and m2=2
clearly
Therefore the two given lines are perpendicular
