Homework Statement Find the x-coordinate of the first point in the region where intersects . Give your answer to 6 significant figures. Homework Equations x_1=x_0- (f(x)/f'(x)) The Attempt at a Solution I equated the two equations and got: 0=tanx-5x I also looked at the graph...

I really need help with this, its due in a few hours. =/

Homework Statement Ship A is located 3.5 km north and 2.8 km east of ship B. Ship A has a velocity of 22 km/h toward the south and ship B has a velocity of 40 km/h in a direction 37° north of east. At what time is the separation between the ships least? Homework Equations...

I also tried the vector equations: (V_ax+V_ay)=(V_abx+V_aby)+(V_bx+V_by) or (-15.55i+15.55j)=(V_abx+V_aby)+(-22.22i+18.64j) so when I separate the equations I get: -15.55=V_abx-22.22 V_abx=6.67i 15.55=V_aby+18.64 V_aby=-3.09 therefore V_ab=(6.67i+3.09j) so the...

So I'm looking for V_ab( velocity of a with respect to b), therefore the velocity of a(V_a) is equal to the velocity of b(V_B) plus the velocity of a with respect to b(V_ab) and I know both a and b so: V_a=V_ab+V_b 22=V_ab+29 -7=V_ab however is is showing as incorrect(I used 7 since...

Homework Statement Two ships, A and B, leave port at the same time. Ship A travels northwest at 22 knots and ship B travels at 29 knots in a direction 40° west of south. (a) What is the magnitude the velocity of ship A relative to B? (b) What is the direction of the velocity of ship A...
