5000 or 1/2 becsoe it has two sides and if you flip it is a 50% chance that you will get head or tails.
if you do not understand plz let me know.

5,000 because a coin has 2 sides so there is 50% chance flipping on tails.

the vertex form of the equation of a parabola is y=(x-5)2+16. what is the standard form of the equation

Reika [66]

Answer:

y = x² - 10x + 41

Step-by-step explanation:

The standard form of a quadratic is ax² + bx + c : a ≠ 0

Given

y = (x - 5)² + 16 ← expand (x - 5)²

= x² - 10x + 25 + 16

= x² - 10x + 41 ← in standard form

66,681 rounded to the nearest ten thousand??

grandymaker [24]

Hey there! I'm happy to help!

This number is sixty six thousand six hundred eighty one. This means that our ten thousandths place is the first 6.

We look to the right place to see if it is 5 or bigger. It is also six.

Therefore we bump the ten thousands place up 1 to 7 and we make everything else 0, giving us 70,000.

Have a wonderful day! :D

If g(x)= -(3/(4x)) , find g(g(x)) please show work.

ivann1987 [24]

Answer:

$g(g(x)) = x$

Step-by-step explanation:

$g(x) = -\dfrac{3}{4x}$

$g(g(x)) = -\dfrac{3}{4g(x)}$

$g(g(x)) = -\dfrac{3}{4(-\frac{3}{4x})}$

$g(g(x)) = -\dfrac{3}{4} \div (-\frac{3}{4x})$

$g(g(x)) = -\dfrac{3}{4} \times (-\frac{4x}{3})$

$g(g(x)) = \dfrac{3 \times 4x}{4 \times 3}$

$g(g(x)) = x$
