What are the coordinates of (-4,-2) rotating 90° counterclockwise?
1 answer:
Answer:
(2, -4)
Step-by-step explanation:
The rotation of an object <u>turns</u> the object around a <u>fixed point</u> called the center of rotation.
A <u>rotation</u> of 90° counterclockwise means:
A 90° rotation counterclockwise with the origin (0, 0) as the center of rotation.
The rule for a counterclockwise rotation of 90° about the origin is:
(x, y) → (-y, x)
Therefore:
(-4, -2) → (2, -4)

In this case, m=-2 and with the point (4, 10) we can find the value of b:
We found that b = 18, so:
Answer:
13 ft.
Step-by-step explanation:
Lateral Surface area of a cube is the area of 4 sides, front side, back side, left side face and right side face.
It can be seen seen from the attached figure as well.
Each face in a cube is a square. And each side in the cube is equal.
So, Lateral surface area is nothing but 4 area of a square.
And we know that area of a square = .
Hence, Lateral surface area =
As per question:
= 676
Hence, side length of cube = 13 feet.
