La distance parcourue (en ´) par un parchutiste lors de sa chute libre varie en fonction de la durée t du saut (en s ), La fonction qui traduit cette situation est
d: t—>89t
1) La distance parcourue est-elle proportionnelle à la
durée t du saut de sa chute ? Justifier la réponse.
2) a) Quelle est l'image du nombre 1 par la
fonction d?
b) En déduire la vitesse (en m/s) du parachutiste,
3) Quelle distance a-t-il parcourue en 1 minute?
4) Quelle est la durée, arrondie a la seconde près,
d'une chute libre de 4500 m?

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
