Answer:

Step-by-step explanation:
Given equation can be  re written as 
 ............(i)
............(i)
Now it is given that y(π/2) = 2e
Applying value in (i) we get
ln(2e) = sin(π/2) + c
=> ln(2) + ln(e) = 1+c
=> ln(2) + 1 = 1 + c
=> c = ln(2)
Thus equation (i) becomes
ln(y) = sin(x) + ln(2)
ln(y) - ln(2) = sin(x)
ln(y/2) = sin(x)

 
        
             
        
        
        
Given : A inequality is given to us . The inequality is 19 ≥ t + 18 ≥ 11 .
To Find : The correct option between the given ones . To write the compound inequality with integers .
Solution : The given inequality to us is 19 ≥ t + 18 ≥ 11 . Let's simplify them seperately . 

⇒ 19 ≥ t + 18 .
⇒ t + 18 ≤ 19 . 
⇒ t ≤ 19 - 18 .
⇒ t ≤ 1  = 1 ≥ t .  ..................(i)

⇒ t + 18 ≥ 11 .
⇒ t ≥ 11 - 18. 
⇒ t ≥ -7 . ....................(ii) 
<u>On</u><u> </u><u>combing</u><u> </u><u>(</u><u>i</u><u>)</u><u> </u><u>&</u><u> </u><u>(</u><u>ii</u><u>)</u><u> </u><u>.</u>

This means that t is less than or equal to 1 but greater than or equal to (-7) .
