Part A equals 5
part B equals 1/2 and 1 hour
part C equals you just have to add all the times together where the dots are
Answer:
vr =
vp = 486.22 j + 205.9 j
Theta 
Step-by-step explanation:
The resultant velocity vr = vp + vw
vp = vector velocity of plane and
vw = vector velocity of wind
vr = vector resultant velocity
in one hour the plane travels 540 miles and hence the speed is 540 mph
Hence vr =
vp = 486.22 j + 205.9 j
Theta

Y=d-3. Y is equal to the cost of the sweaters before the price was raised. D represents the price of the sweaters after the price jump. The three is how much the sweater price was raised by. Say the new price of the sweaters are $29.99 each. You would plug in 29.99 for d. y=29.99-3. The new price of the sweaters would be $26.99 (this is just a sample problem)
If you want it to be y=mx+b form then the equations should look like this: y=x+5 and y=-1/3x+1.
