Answer:
cos x = 0.5
Step-by-step explanation:
Using the trigonometric identity
cot x = 
Given
sin x cot x = 0.5, then
sin x × = 0.5 ← cancel sin x on numerator/ denominator
cos x = 0.5
Answer:
y=x+3
Step-by-step explanation:

D= distance
t= time
s= speed
FORMULA
Distance= speed * time
STEP 1:
Find total distance
Jim's D + John's D= 3 miles
STEP 2:
Distance= (Jim's speed * time) + (John's speed * time)
D= 4t + 5t
3 miles= 9t
divide both sides by 9
3/9= t
reduce by 3
1/3 hour= t
STEP 3:
1 hour= 60 minutes
=1/3 * 60
=(60/3)
= 20 minutes
ANSWER: They will travel 20 minutes before they meet.
