$\bf h=-16t^2+255\implies h=-16t^2+0t+255
\\\\\\
~~~~~~~~~~~~\textit{quadratic formula}\\\\
\begin{array}{lcccl}
h=& -16 t^2& +0 t& +255\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array} 
\qquad \qquad 
h= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a}
\\\\\\
h=\cfrac{-0\pm\sqrt{0^2-4(-16)(255)}}{2(-16)}\implies h=\cfrac{\pm\sqrt{16320}}{-32}
\\\\\\
h=\cfrac{\pm\sqrt{8^2\cdot 255}}{-32}\implies h=\cfrac{\pm 8\sqrt{255}}{-32}\implies h=\cfrac{\mp \sqrt{255}}{4}
\\\\\\
h\approx \mp 3.992179856$

Which number is equal to 10 Superscript negative 3? –1,000 –30 0.001 0.003

Karolina [17]

<u>Given</u>:

The given expression is $10^{-3}$

We need to determine the equivalent number.

<u>Equivalent expression:</u>

To determine the equivalent number, let us solve the expression $10^{-3}$

Thus, let us apply the exponent rule $a^{-b}=\frac{1}{a^{b}}$ , we get;

$10^{-3}=\frac{1}{10^{3}}$

Also, the term 10³ can be written as $10^{3}=1000$

Thus, we get;

$\frac{1}{1000}$

Dividing, we get;

0.001

Hence, the equivalent number is 0.001

Hence, Option c is the correct answer.
