Calvin work as an air conditioning contractor the customer wants to buy an air condition for his family room his room measure 30

Verdich [7]

ANSWER

$3840 {ft}^{3}$

EXPLANATION

The room represents a rectangular prism or a cuboid.

The dimensions of the room are 30 feet by 16 feet by 8 feet(height).

The volume of a rectangular prism is

$= base \: area \: \times \: height$

Substitute the given values

$= 30 \times 16 \times 8 {ft}^{3}$

Simplify:

$= 3840 {ft}^{3}$

Hence the cubic feet of air in the room is 3,840ft³.

Point A has coordinates (3,4). After a translation 4 units left, a reflection across the x-axis, and a translation 2 units down,

jeka94

Answer:

The coordinates of the image of point A are (-1, -6)

Step-by-step explanation:

Let us revise the rule of translation to the left, down, and reflection across the x-axis

If the point (x, y) translated horizontally to the left by h units then its image is (x - h, y) ⇒ T (x, y) → (x - h, y)

If the point (x, y) translated vertically down by k units then its image is (x, y - k) ⇒ T (x, y) → (x, y - k)

If the point (x, y) reflected across the x-axis, then its image is (x, -y), the rule of reflection is rx-axis (x, y) → (x, -y)

∵ The coordinates of point A are (3, 4)

∵ It is translated 4 units left

∴ h = 4

→ By using the 1st rule above

∴ Its image is (3 - 4, 4)

∴ Its image is (-1, 4)

∵ Its is reflected across the x-axis

→ By using the 3rd rule above change the sign of its y-coordinate

∴ The new image is (-1, -4)

∵ It is translated 2 units down

∴ k = 2

→ By using the 2nd rule above

∴ The final image is (-1, -4 - 2)

∴ The final image is (-1, -6)

∴ The coordinates of the image of point A are (-1, -6).
