Which is the angle measure represented by 1.5 rotations counterclockwise? C. 540° a. -540 d. 720 b.-720 Please select the best answer from the choices provided О А О В Oc OD. NEED HELP FAST

C

Step-by-step explanation:

Remember that counter-clockwise angles are positive while clockwise angles are negative.

In other words, since we are doing a counter-clockwise rotation, our answer should be a positive value. Hence, we can eliminate A and B.

Recall that each rotation is equivalent to 360°.

So, one-half of a rotation is equivalent to 180°.

Therefore, a 1.5 rotation is equivalent to 360° + 180° = 540°.

And since our angle must be positive, our answer is 540°.

C is the correct choice.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
