The distance a free falling object had traveled can be modeled by the equation d=1/2 at^2 where a is acceleration due to gravity

luda_lava [24]

D=(1/2)*a*t²
Multiply both sides by 2
2d= a*t²

Divide both sides by a
2d/a=t²

Now take square root both sides. You will get t in terms of d and a

Which of the following is not an integer?

In-s [12.5K]

Answer:

$-\frac{54}{7}$

Step-by-step explanation:

The first number is $\sqrt{\frac{64}{4} }$

We simplify to get: $\sqrt{\frac{64}{4} }=\sqrt{16}=4$

The second number is $-\frac{54}{7}$ .

This number can be rewritten as $7 \frac{5}{7}=7.714285714287$

This is not an integer

The third number is $(\frac{-25}{5})^2$

We simplify to get: $(\frac{-25}{5})^2=(-5)^2=25$

This is also an integer.

The correct answer is $-\frac{54}{7}$ .
