J'ai besoin des étapes donc merci d'avance. Calculer la vitesse moyenne de la voiture entre t 0,5 et 3 seconde.

donné : 130km/h au bout de 4 seconde et d(t)=480t/t+12

Comment calculer un taux de variation de fonctionn d entre 0,5 et 0,5+h. V(h)=460,8/h+12,5.

comment peut-on interprète le Vh en terme de vitesse.
démontré la fonctionne d est en 0,5 et la distance instantanée du véhicule t=0,5​

three-fourths of an hour

36÷48=0.75

0.75=

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
