A car moving at a constant speed passed a timing device at t = 0. After 8 seconds, the car has traveled 936 ft. Write a linear f
Ahat [919]

Answer:

Buenos días;

1) La ecuación de la velocidad en un movimiento uniformemente acelerado (M.U.A) es:

V=V₀+at.

V=30 m/s-2 m/s².t

Ahora elimina las unidades (m/s, m/s₂), y tendrás la ecuación de la velocidad en función del tiempo.  

V(t)=30-2t.

Sol: la ecuación de la velocidad en función del tiempo es : V(t)=30-2t.

2) La ecuación de la posición en función del tiempo en un M.U.A  es:

X=X₀+V₀.t+(1/2).a.t²

X=0+30 m/s.t+(1/2).(-2 m/s²).t²

Eliminas las unidades, y tendrás la ecuación de la posición en función del tiempo.

X(t)=30.t-t².

Sol: la ecuación de la posición en función del tiempo es: X(t):30t-t²

Un saludo.

A given line has the equation .
SSSSS [86.1K]

Answer:

  A.  Y = -6X + 9

Step-by-step explanation:

Solving for y, we can find the slope of the given line. It is the coefficient of x, 1/6.

  -12y = -2x -1

  y = 1/6x +1/12

The perpendicular line will have a slope that is the negative reciprocal of this:

  m = -1/(1/6) = -6

The y-intercept will be the y-value corresponding to x=0. That value is b=9, given to us by the point the line is to go through. So, we have the slope-intercept form ...

  y = mx + b

  y = -6x + 9
