Write this number in standard form.4 million, 5 thousand, and twenty-one thousandths
Standard form is also known as the numerical form
=> <span>4 million = 4 000 000
=> 5 thousand = 5 000
=> twenty-one thousandths = .020
Thus, 
=> 4 000 000 + 5 000 + .020 = 4 005 000.020</span>

The other leg is 12cm long.

Step-by-step explanation:

Given,

Hypotenuse = c = 15cm

One leg = a = 9cm

Other leg = b

As the triangle is right angled, therefore, using Pythagoras theorem;

a^2+b^2=c^2\\(9)^2+b^2=(15)^2\\81+b^2=225\\b^2=225-81\\b^2=144\\

Taking square root on both sides;

\sqrt{b^2} =\sqrt{144} \\b=12\ cm

The other leg is 12cm long.

Keywords: triangle, square root

Given the graph, find an equation for the parabola.
Sauron [17]

Answer:

\Large \boxed{\sf \bf \ \ y=\dfrac{1}{16}(a-3)^2-2 \ \  }

Step-by-step explanation:

Hello, please consider the following.

When the parabola equation is like

y=a(x-h)^2+k

The vertex is the point (h,k) and the focus is the point (h, k+1/(4a))

As the vertex is (3,-2) we can say that h = 3 and k = -2.

We need to find a.

The focus  is (3,2) so we can say.

2=-2+\dfrac{1}{4a}\\\\\text{*** We add 2. ***}\\\\\dfrac{1}{4a}=2+2=4\\\\\text{*** We multiply by 4a. ***}\\\\16a=1\\\\\text{*** We divide by 16. ***}\\\\a=\dfrac{1}{16}

So an equation for the parabola is.

\large \boxed{\sf y=\dfrac{1}{16}(a-3)^2-2 }

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

How to find where a function is increasing or decreasing?
lys-0071 [83]
Take the derivative, then plug in any number in the domain.  If the number is positive the function is decreasing, if it's negative it's decreasing.
