Chapter 13.7, Problem 29PSD

a.

To determine

To find the coordinates of $C_3$ .

Explanation of Solution

Given:

The given coordinate $C_1=\left(3.5,0\right)$

Calculation:

Since A1 and B1 are being turned around and they are becoming A2 and B2.

Therefore the coordinates of $C_3$ after turning around will be

  $(3,0)$

b.

To determine

To find the coordinates of $D_2$

Explanation of Solution

Given:

The coordinates of $D_1=(4,0)$

Calculation:

The coordinates of D2 will be

  $(7,0)$

c.

To determine

To find the coordinates of $E_2$ in terms of $x_1$

Explanation of Solution

Given:

The coordinates of $E_1=(x_1,0)$

Calculation:

The coordinates of $E_2$

  $\left(2x_1,0\right)$
