Sometimes it's hard not to assume something from a picture. Just because two of the sides look congruent doesn't mean they are. The information in the diagram (and geometry knowledge and logic!) are your guide.

The distance, in feet, a stone drops in tt seconds is given by d(t)=16t2d(t)=16t2. The depth of a hole is to be approximated by

Verizon [17]

Define the distance through the equation

$x=16t^2$

The distance against the time is given by

$\Delta x = 32 t \Delta t$

$\Delta t = \frac{2}{10}s$

When t=2s,

$\Delta x = 32(2)\frac{2}{10}$

$\Delta x = 12.8$

There is a error in 12.8feet.

b) When t=5sec

$\Delta x= 32t\Delta t$

$\Delta x= 32(5)*\frac{2}{10}$

$\Delta x = 32$

There is a error in 32 feet.
