c = 94.2

Area and volume math question pretty simple please help no explanation needed just answers
Svetlanka [38]

Solution ,

length = 4m

breadth = 1.2m

height = 0.3m

Now

Area = l × b

= 4m × 1.2 m

= 4.8m²

Now

Volume = l × b × h

= 4m × 1.2m × 0.3m

= 1.44 m³

Wha) is the image of the point (9,2) after a rotation of 90° counterclockwise about the origin?
ElenaW [278]

Given the point:

(x, y) ==> (9, 2)

Let's find the new point of the image after a rotation of 90 degrees counterclockwise about the origin.

To find the image of the point after a rotation of 90 degrees counterclockwise, apply the rules of rotation.

After a rotation of 90 degrees counterclockwise, the point (x, y) changes to (-y, x)

Thus, we have the point after the rotation:

(x, y) ==> (-y, x)

(9, 2) ==> (-2, 9)

Therefore, the image of the points after a rotation of 90 degrees counterclockwise is:

(-2, 9)

ANSWER:

(-2, 9)
