1.- En un teatro la base de un candil está a 160 pies sobre el piso del vestíbulo. Supongo

que el fantasma de la ópera suelta el candil y lo deja caer desde el reposo hasta

estrellarse en el piso, la ecuación que describe el desplazamiento del candil se presenta a

continuación

() = −16 + 160

a) ¿qué rango de valores son

admisibles para el contexto del problema?

b) Determinar la velocidad instantánea del candil en 1 seg. Y

1.5 segundos

c) Determine el tiempo que le tomara al candil llegar al suelo

d) Cual es la rapidez cuando el candil llega al piso

marco saved more.   he saved $35 more.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
