1.Calcular la aceleración (en m/s2) que se aplica para que un móvil que se desplaza en línea recta a 100.0 km/h reduzca su velocidad a 53.0 km/h en 40 segundos 2.En una competencia un ciclista debe recorrer 1000 km en 6hrs. Determine la velocidad del ciclista en mt/seg.

3.Si un automóvil que viaja a 22 mts/seg y recorre una distancia de 6.5km ¿Determine el tiempo que tardó en llegar a su destino? De la respuesta en horas

4.Encuentre el vector resultante de un objeto que se desplaza de un punto A) 40 km N35ºE, luego se desplaza a un punto B) 70 km al Sur y llega a un punto C) 50 km S55º0

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
