IF the side length is 10cm , then the length of diagonal of the base of the cube(x) is X² =(10)²+(10)² =200cm  so x = 10√2cm
so the length of diagonal of the cube(y) is
y² = (10)² + (10√2)² =300  so y =10√3cm

The equation, y = (1/4)x, is an example of what kind of variation?
lakkis [162]

Answer:

I would stay direct vartation

Step-by-step explanation:

For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.

Are there concepts/processes to strictly follow in writing radicals as expressions with rational exponents?
Eva8 [605]

Answer:

The concept or process is x^{\frac{m}{n}}=(\sqrt[n]{x})^m.

Step-by-step explanation:

Consider the provided information.

The following property can be used to rewrite each radical as an exponent.

The numerator tells the power of the resulting rational exponent, and the denominator of the rational exponents tells the root of that number.

x^{\frac{m}{n}}=(\sqrt[n]{x})^m

For example:

(27)^{\frac{2}{3}}=(\sqrt[3]{27})^2

(27)^{\frac{2}{3}}=(3)^2

(27)^{\frac{2}{3}}=9

Hence, the concept or process is x^{\frac{m}{n}}=(\sqrt[n]{x})^m.
