Her vertical position is described by y(t). She reach the ground when y(t) = 0 so:

$y(t)=0\\\\-16t^2+100=0\quad|-16t^2\\\\100=16t^2\quad|:16\\\\t^2=6.25\quad|\sqrt{(\dots)}\\\\\boxed{t=2.5}$

She reach the ground after 2.5 seconds and she will be:

$x(2.5)=8\cdot2.5=\boxed{20}$ (meters) from the cliff.

What is the perimeter of triangle ABC?

ddd [48]

Answer: 24 units.

Step-by-step explanation: Count out how many units long AB is. AB goes from -3 to 3, for a length of 6 units.

Count out how long AC is. AC goes from 4 to -4, for a length of 8 units.

To find BC, use the Pythgorean theorem (a^2+b^2=c^2). 8^2 is 64, and 6^2 is 36. Add 64 and 36 to get 100. Then find the square root of 100, which is 10.

Add all the lengths. 6+8+10=24.
