The first 27yard section of a roller cost can be expressed by the equation y=-0.0001x^6*0.0069x^5-0.1681x^4+1. 6979x^3 - 6.167x^2+6.6x-32.4 the x axis represents the ramp that the maintenance crew uses as a platform to work on parts of the roller coaster and the y axis represents the ladder used by the crew to access the platform. During which intervals is the ride going downhill?

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

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

i think asking google will you get the answer to that question

answer: 8

step-by-step explanation: if you add the possibilities 5 different flavor and 3 different sizes 5+3=8
