Answer:

52 measures

Step-by-step explanation:

Let s represent the length of the second song. Then the first song's length is 108 -s, and the difference in length is ...

(108 -s) -(s) = 4

108 -2s = 4 . . . .collect terms

54 -s = 2 . . . . divide by 2

52 = s . . . . . add s-2

Grace's second song is 52 measures long.

Which of the following angles can be trisected using only a compass and straightedge?

ZanzabumX [31]

How is the graph of the parent function of y = RootIndex 3 StartRoot 0.5 x EndRoot transformed to produce the graph y = RootInde

lana66690 [7]

Answer:

Horizontal stretch by a factor of ½.

Step-by-step explanation:

We were given the parent function as:

$y = \sqrt[3]{0.5x}$

This was transformed to:

$y = \sqrt[3]{x}$

Let

$g(x) = \sqrt[3]{0.5x}$

and

$f(x) = \sqrt[3]{x}$

Then:

$f(x) = g(2x)$

Hence the parent function has been stretched horizontally by a factor of 1/2 to obtain the transformed function.
