In which quadrant will the image FGH lie after a counterclockwise rotation of 1980 degrees? Explain how you made your prediction

Nata [24]

A 360 degrees counter-clockwise rotation will bring the triangle at the same place.

So, divide 1980 by 360 and find the remainder.

On dividing, we can find that

1980 = 5(360) + 180

A 1800 degrees rotation will rotate the triangle 5 times and will bring it in the same place.

A further 180 degrees rotation will rotate the triangle to two quadrants back and will bring it in the first quadrant.

Someone please I just want to get done with this

Answer:

{10, 20, 30, 40, 50, 60}

Step-by-step explanation:

The function is:

$f(x)=10x\\\{x\in \mathbb{N}|1\leq x \leq 6\}$

State that the tange of function is the set of all output values of a function. Therefore, the answer cannot be {1, 2, 3, 4, 5, 6} and $1\leq x\leq 6$ . The answer is not $10\leq y\leq 60$ because its output will always be a natural number and it's not stated in the answer, like I did above. The answer is {10, 20, 30, 40, 50, 60}
