Express 78 billion in scientific notation

ryzh [129]

Answer:

$7.8 * 10^{10}$ is scientific notation of 78 billion

Step-by-step explanation:

For scientific notation , follow the following notation:

$a * 10^{b}$ -------->(equation 1)

Let, $a^{'} = 78 billion$

$a^{'} = 78000000000$

$a^{'} = 78000000000.0$

In standard form

$a = 7.8000000000$

$a = 7.8$

As decimal point move 10 places from right to left, therefore

b = 10

Put the value of 'a' and 'b' in (equation 1)

$7.8 * 10^{10}$ is scientific notation of 78 billion

What are the solution(s) to the quadratic equation 9x2 = 4?

Kaylis [27]

Answer:

Option B.

Step-by-step explanation:

The given quadratic equation is

$9x^2=4$

We need to find the solution of given quadratic equation.

Divide both sides by 9.

$\frac{9x^2}{9}=\frac{4}{9}$

$x^2=\frac{4}{9}$

Taking square root on both sides.

$x=\pm\sqrt{\frac{4}{9}}$

$x=\pm\frac{2}{3}$

The solution of given equation are $x=\frac{2}{3}$ and $x=-\frac{2}{3}$ .

Therefore, the correct option is B.
