13) A point, beginning at [tex]\((0, -2)\)[/tex], undergoes the following composition of translations. Write an ordered pair for the point's final position.

[tex]\[ T_{\langle 3, 5 \rangle} \text{ and } T_{\langle 0, -1 \rangle} \][/tex]


Sagot :

To solve this problem, we need to apply the given translations to the initial position of the point step by step. Let's start by identifying the initial position and the translations:

1. Initial Position:
[tex]\((0, -2)\)[/tex]

2. First Translation Vector:
[tex]\(\langle 3, 5 \rangle\)[/tex]

3. Second Translation Vector:
[tex]\(\langle 0, -1 \rangle\)[/tex]

### Step-by-Step Solution:

#### Step 1: Apply the First Translation
We start by applying the first translation vector [tex]\(\langle 3, 5 \rangle\)[/tex] to the initial position [tex]\((0, -2)\)[/tex].

Adding the components of the first translation vector to the initial position:

[tex]\[ \begin{aligned} x' &= 0 + 3 = 3 \\ y' &= -2 + 5 = 3 \\ \end{aligned} \][/tex]

So, after the first translation, the point's new position is:

[tex]\[ (3, 3) \][/tex]

#### Step 2: Apply the Second Translation
Next, we apply the second translation vector [tex]\(\langle 0, -1 \rangle\)[/tex] to the position obtained after the first translation, which is [tex]\((3, 3)\)[/tex].

Adding the components of the second translation vector to the position obtained after the first translation:

[tex]\[ \begin{aligned} x'' &= 3 + 0 = 3 \\ y'' &= 3 - 1 = 2 \\ \end{aligned} \][/tex]

So, after the second translation, the point's final position is:

[tex]\[ (3, 2) \][/tex]

### Final Answer:
The ordered pair for the point's final position after undergoing the translations [tex]\(T_{\langle 3,5 \rangle}\)[/tex] and [tex]\(T_{\langle 0,-1 \rangle}\)[/tex] starting from [tex]\((0, -2)\)[/tex] is:

[tex]\[ (3, 2) \][/tex]
