Answer:
Vel_jet_r = (464.645 mph) North + (35.35 mph) East
||Vel_jet_r|| = 465.993 mph
Step-by-step explanation:
We need to decompose the velocity of the wind into a component that can be added (or subtracted from the velocity of the jet)
The velocity of the jet
500 mph North
Velocity of the wind
50 mph SouthEast = 50 cos(45) East + 50 sin (45) South
South = - North
Vel_ wind = 50 cos(45) mph East - 50 sin (45) mph North
Vel _wind = 35.35 mph East - 35.35 mph North
This means that the resulting velocity of the jet is equal to
Vel_jet_r = (500 mph - 35.35 mph) North + 35.35 mph East
Vel_jet_r = (464.645 mph) North + (35.35 mph) East
An the jet has a magnitude velocity of
||Vel_jet_r|| = sqrt ((464.645 mph)^2 + (35.35 mph)^2)
||Vel_jet_r|| = 465.993 mph
Answer:
$7.10
Step-by-step explanation:
0.71 x 10= 7.10
Answer:
im guessing you're trying to find where the lines will meet at, so the lines will meet at (1,-1)
Step-by-step explanation:
sadly it doesnt allow me to add in a photo but ill tell you a good enough explanation of what to draw, for y=3x+2 your line starts at 2 on the y axis and goes down (-3/1)
for y=3x-4 your line starts at -4 and go up by 3/1
hope this helped, not sure if you need anything more.
Answer:
1408
What you have to do is 645 + 763 = 1408 that's how you doing I think so and sorry if I did it wrong
Answer: b=8in
Step-by-step explanation:
The base of the triangle is 8in because, as the shape has been split into 2 shapes, the base of the triangle is the same as the length of the rectangle.
Hope this helps :)
