the volume of a triangular prism is 42 cubic centimeters. what is the volume of a similar prism that is twice as large as large

Dmitriy789 [7]

Answer:

The volume of the similar prism is $336\ cm^{3}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> the scale factor

x----> the volume of the larger prism

y----> the volume of the smaller prism

$z^{3}=\frac{x}{y}$

In this problem we have

$z=2$ -----> the scale factor

$y=42\ cm^{3}$

substitute and solve for x

$x=42(2^{3})=336\ cm^{3}$

Which equation below does NOT represent a function of X A) x=y^2 B) y=x C) y = |x| D) y=x^2 E) y=1

vlabodo [156]

Answer:

A) $x = y^{2}$

Step-by-step explanation:

An equation is a function of $x$ when $x$ is the independent variable, that is:

$y = f(x)$ (1)

Where $y$ is the dependent variable.

According to this, $x = y^{2}$ does not represent a function of $x$ , since the independent variable is a function of $y$ , that is, $x = f(y)$ . Therefore, the correct answer is A.
