Determine the general form of the equation for the circle (x + 0.1)2 + (y – 0.1)2 = 0.5. a)x2 + y2 + 0.1x – 0.1y – 0.3 = 0 b)x2 + y2 + 0.2x – 0.2y – 0.48 = 0 c)x2 + y2 + 0.1x – 0.1y – 0.48 = 0 d)x2 + y2 + 0.2x – 0.2y – 0.3 = 0

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
