Answer:

a = 0.027 m/s²

Step-by-step explanation:

a = v₁ - v₀ / t

v₁ = 3.5

v₂ = 3.1

t = 15

then

a = (3.5 - 3.1) / 15

a = 0.4 / 15

a = 0.027 m/s²

1a. You can't do much for it, answer could be x(x+8)

1b. (x+5)(x+3)

1c. (x + 3y)(x - 3y)

1d. (5x - 4) (x + 2)

2. It's very likely you need a protractor and a ruler for this. If not, tell me and I'll try to find it.

Triangle ABC has vertices A(−3, 1), B(−3, 4), and C(−7, 1).
Lina20 [59]

The solution to the questions are

  • The description of the translation in words is horizontal shift to the left  by 4 units and vertical shift up by 3 units
  • A(−7, 4), B(−7, 7), and C(−11, 5).
  • ∆ABC is congruent to ∆A"B"C"

<h3>Part A: How is the translation described with words?</h3>

We have the translation to be:

∆ABC is translated according to the rule (x, y) → (x − 4, y + 3) to form ∆A'B'C'

The translation rule (x, y) → (x − 4, y + 3) involves a horizontal translation and a vertical translation

So, the description of the translation in words is horizontal shift to the left  by 4 units and vertical shift up by 3 units

<h3>Part B: Where are the vertices of ∆A'B'C' located?</h3>

We have:

A(−3, 1), B(−3, 4), and C(−7, 1).

When the rule applied, the points become

A(−7, 4), B(−7, 7), and C(−11, 5).

<h3>Part C: Is ∆ABC congruent to ∆A"B"C"?</h3>

Here, the transformation rule is given as:

Triangle A'B'C' is rotated 90° clockwise about the origin to form ∆A"B"C"

A clockwise rotation by 90° is a rigid transformation

This means that the sides and angles of both shapes are congruent

Hence, ∆ABC is congruent to ∆A"B"C"
