Which of the following represents... in radical form?

IgorLugansk [536]

$\mathrm{Apply\:radical\:rule\:}\sqrt[n]{a^m}=a^{\frac{m}{n}}$

$\sqrt[9]{x^4}=x^{\frac{4}{9}}$

$5\sqrt[9]{x^4}=5x^{\frac{4}{9}}$

Thus

$5x^{\frac{4}{9}}=5(x^4)^{1/9}$

$=5\sqrt[9]{x^4}$

Answer the problem :)

Tomtit [17]

The domain is the value of x. In this case, -3≤x≤7
the range is the value of y. in this case, -1≤y≤9

this is not a function, because the same x value has two corresponding y values. For example, when x=5, y=0 or y=8

It IS a function if every x value has only one corresponding y value.

In the formula for the volume of a cylinder, how is the area of the base determined?

Len [333]

Answer:

area of base = $\pi r^2$

where 'r' is the radius

Step-by-step explanation:

Volume of the cylinder formula = $\pi r^2h$

volume of cylinder = area of base * height

The base of a cylinder is a circle. so we use the area of circle for the base of cylinder while finding volume

We know area of the circle is $\pi r^2$

So area of the base of cylinder is $\pi r^2$

To find volume of the cylinder , we multiply the base of the cylinder with height

To determine the base of the cylinder we need radius of the cylinder

area of base = $\pi r^2$

where 'r' is the radius

When a decimal is written in word form, what indicates that the equivalent form is a mixed number and not a fraction?

Ede4ka [16]

<span>If you are reading a story problem that says one and a half this would indicate the mixed number 11/2 or the decimal 1.5, which are all equivalent.</span>
