jarptica [38.1K]

Answer:

She traveled 70560 m.

Step-by-step explanation:

Given :

Acceleration (g) =   -9.8m/s^{2}

Time : 120 seconds .

To Find : Distance traveled

Solution:

Since we are given that there is a free fall .

So, we will use the formula:   d=\frac{1}{2} gt^{2}

Now put the given values in the formula :

⇒d=\frac{1}{2}*(-9.8)*(120)^{2}

⇒d=\frac{1}{2}*(-9.8)*14400

⇒d=\frac{-141120}{2}

⇒d=-70560

Negative sign shows the direction only.

Hence she traveled 70560 m.

Z=8+6x-px<br><br>solve for x
ohaa [14]
      z = 8 + 6x - px   Subtract 8 from both sides
z - 8 = 6x - px          Factor the x out of 6x - px
z - 8 = x (6 - p)         Divide both sides by (6 - p)
\frac{z - 8}{6 - p} = x   Switch the sides to make it easier to read
x = <span>\frac{z - 8}{6 - p} </span>
