It will look like a half branch of  a parabola opened upward

You can either create a table by choosing values of y  0, 1, 2, 3, 4 and so on

or

A = 0.25 d^2

so the center is (0,0)

and for d = (2)

A = 1

and for A = 0.25

d = 1 

and try to draw it with just 3 points

Which expressions below equal a rational number? Choose all that apply. 4/5 + 3/8; sqrt(100) + sqrt(5); 7sqrt(5) - sqrt(245); (4
masha68 [24]

Answer:

Step-by-step explanation:

<h3>Rational number</h3>

1)  \dfrac{4}{5}+\dfrac{3}{8}\\\\\dfrac{4}{5} \ \text{is a rational number} \ and \ \dfrac{3}{8} \ \text{is a rational number}\\\\\dfrac{4}{5}+\dfrac{3}{8} \ \text{is also a rational number}

b) \sqrt{100}+\sqrt{5} = 10+\sqrt{5}\\\\\sqrt{5} \ \text{is a irrational number}. \\\\ \text{Rational number added to irrational number will result in an irrational number}\\\\10 + \sqrt{5} \ is \ not \ a \ rational \ number.

c)

7\sqrt{5}-\sqrt{245}=7\sqrt{5}-\sqrt{7*7*5}

                   = 7\sqrt{5}-7\sqrt{5}\\\\=0\\\\\text{\bf $ 7\sqrt{5}-\sqrt{245}$ ia a rational number}

d)

(4\sqrt{7})*(2\sqrt{7})=4*2*\sqrt{7*7}\\

                       = 4*2*7

                       = 56

4\sqrt{7}*2\sqrt{7} \ \text{\bf is a rational number}

Help!!!!
Luda [366]

Answer:

\large\boxed{\dfrac{5}{10}}

Step-by-step explanation:

\sqrt[3]{\dfrac{125}{1000}}\qquad\text{use}\ \sqrt[n]{\dfrac{a}{b}}=\dfrac{\sqrt[n]{a}}{\sqrt[n]{b}}\\\\=\dfrac{\sqrt[3]{125}}{\sqrt[3]{1000}}=\dfrac{5}{10}\\\\\\\sqrt[3]{125}=5\ because\ 5^3=125\\\\\sqrt[3]{1000}=10\ because\ 10^3=1000
