Jordan wants to prove △PQR≅△STU using a sequence of rigid motions. This is Jordan's proof. Translate △PQR to get △P'Q'R' with R'
aleksandr82 [10.1K]

Answer:

A. △P'Q'R' does not equal △P''Q''R''.

B. Reflecting across UT would change the orientation of the figure.

C. The sequence does not include a reflection that exchanges U and S.

D. Rotating about point U is not a rigid motion because it changes the orientation of the figure.

E. Translating point R' to Q' is a non-invertible transformation because it changes the location of P'.

(D) Rotating about U is not a rigid motion because it changes the orientation of the figure. [I think D is an incorrect answer choice.]

Step-by-step explanation:

Proof No.1

Jordan wants to prove △PQR≅△STU using a sequence of rigid motions. This is Jordan's proof. Translate △PQR to get △P'Q'R' with R'=U. Then rotate △P'Q'R' about point U to get △P''Q''R''. Since translation and rotation preserve distance, R''Q''=RQ=UT, and Q''=T. Reflect △P''Q''R'' across UT to get △P'''Q'''R''. Since reflection preserves distance, P'''R'''=PR=US, and P'''=S. A sequence of rigid motions maps △PQR onto △STU, so △PQR≅△STU.

Proof No.2

Jordan wants to prove △PQR≅△STU using a sequence of rigid motions. This is Jordan's proof. Translate △PQR to get △P'Q'R' with R'=U. Then rotate △P'Q'R about point U to get △P''Q''R'' so that R''Q'' and UT coincide. Since translation and rotation preserve distance, R''Q''=RQ=UT, and Q''=T. Reflect △P''Q''R'' across UT to get △P'''Q'''R''. Since reflection preserves distance, P'''R'''=PR=US, and P'''=S. A sequence of rigid motions maps △PQR onto △STU, so △PQR≅△STU.

The graph of f(x) = |x| is reflected across the y-axis and translated to the left 5 units. Which statement about the domain and
aksik [14]

Both the domain and range of the transformed function are the same as those of the parent function.

Option A is the correct answer.

The complete question is

Both the domain and range of the transformed function are the same as those of the parent function.

Neither the domain nor the range of the transformed function are the same as those of the parent function.

The range but not the domain of the transformed function is the same as that of the parent function.

The domain but not the range of the transformed function is the same as that of the parent function

<h3>What is a function ?</h3>

A function is a mathematical statement which defines relationship between a dependent variable and an independent variable.

It is given that

f(x) = |x|

The graph is plotted

When the graph is is reflected across the y-axis and translated to the left 5 units.

When reflected across y axis , g(x) = |-x| = |x|

When translated 5 units to the left , g(x) = |x+5|

Both the graph is plotted and attached with the answer

The domain is the any value that can be an input in the function

domain for both the function is {x≥0}

The range is the value of the function that exists at any given time {y≥0}

From the option given

Both the domain and range of the transformed function are the same as those of the parent function.

Option A is the correct answer.
