Situatia notelor la sfarsitul anuluiscolar sunt: stiind ca scoala are 1500 elevi a) cat %din elevi au note sub 5. b)cati elevi au note de 10. c)cati elevi au note inte 8 si9,99. d)cati elevi au note intre 7 si 7,99. e)cati elevi au note intre 5 si 6,99.

Use the distributive property to factor the expression. 15x + 6 a) 2 5 b) − 2 5 c) 3(5x + 2) d) 5(3x + 6)

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.

Varies inversely with x. if y=8.5 when x=-1 find x when y=-1
