You are on a school bus moving slowly as it approaches your house at 2.0 m/s. You get up and hurry to the front of the bus at 4.0 m/s relative to the bus. What is your speed relative to your street? A. 6.0 m/s2 relative to the street
B. 8.0 m/s relative to the street
C. 2.0 m/s relative to the street
D. 6.0 m/s relative to the street

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

ok then what happened.

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
