Se consideră funcția f:R→R, fx=x2-5x+m, mϵR. Să Să determine m pentru care f(0)=3 Să se determine valoarea lui m pentru care minimul functiei este 2. Pentru m=1 determinati punctul de minim al funcției f. Pentru m=4 rezolvați ecuația f(x)=0. VA ROG REPEDE (dau coroana)

You and a friend race across a field to a fence and back. your friend has a 50-meter head start. the equations shown represent you and your friend's distances dd (in meters) from the fence tt seconds after the race begins. find the time at which you catch up to your friend. you: d=∣−5t+100∣d=∣−5t+100∣ your friend: d=∣−313t+50∣∣

The coordinates of a, b, and c in the diagram are a(p,4), b(6,1), and c(9,q). which equation correctly relates p and q? hint: since is perpendicular to , the slope of × the slope of = -1. a. p - q = 7 b. q - p = 7 c. -q - p = 7 d. p + q = 7
