(8.08×10^-10)÷(4.0×10^-3) in scientific notation?

saw5 [17]

Answer:

$\large\boxed{2.02\times10^{-7}}$

Step-by-step explanation:

The scientific notation:

$a\cdot10^k\\\\1\leq a$

We have:

$(8.08\times10^{-10})\div(4.0\times10^{-3})\\\\=\dfrac{8.08\times10^{-10}}{4.0\times10^{-3}}\\\\=\dfrac{8.08}{4}\times\dfrac{10^{-10}}{10^{-3}}\qquad\text{use}\ \dfrac{a^n}{a^m}=a^{n-m}\\\\=2.02\times10^{-10-(-3)}\\\\=2.02\times10^{-7}$

F(x)=(x−2)^2 -9 Find the solutions

Julli [10]

Answer:

x=1 or x=-5

Step-by-step explanation:

The given function is

$f(x) = {(x - 2)}^{2} - 9$

The solutions are the roots of the function.

This is where the graph of the function touches the x-axis.

We set the equation to zero to get:

${(x - 2)}^{2} - 9 = 0$

${(x - 2)}^{2} = 9$

We take square root to get:

${(x - 2)} = \pm \sqrt{9}$

$x - 2= \pm 3$

$x= 2 \pm 3$

$x= 2 - 3 \: or \: x = 2 + 3$

$x = - 1 \: or \: x = 5$
