There are approximately Pi times 10,000,000 seconds in one ____?
MissTica

The number of seconds in a year are 31,557,600 seconds, which gives;

There are approximately Pi times 10,000,000 seconds in one <u>year</u>.

<u />

<h3>How can the given statement be completed?</h3>

The number of seconds in one day = 86,400

The number of seconds in one week = 604,800

The number of seconds in a year = 31,557,600

Therefore;

\mathbf{\dfrac{The \ number  \ of  \ seconds  \ in \  a \  year}{10,000,000}}  = 3.1557600 \ which  \ is \ close \ to \3.14159 \approx \pi

Which gives;

The number of seconds in a year ≈ π × 10,000,000

The completed statement is therefore;

  • There are approximately Pi times 10,000,000 seconds in one <u>year</u>

Which point is an x-intercept of the quadratic function
daser333 [38]
The x-intercept of f(x) = (x + 6)(x - 3)
f(x) = 0 → (x + 6)(x - 3) = 0 → x + 6 =0 or x - 3 =0
x = -6 or x = 3
Therefore the x-intercepts are: (-6; 0) and (3; 0)
Your answer is (-6; 0)
