Answer:

(4,-3)

Step-by-step explanation:

If you graph this point, then it will be in the 3rd quadrant.

A 180 degree rotation will put it in the 1st quadrant.

And the extra 90 degrees will put in in the 4th quadrant, so we know that in (x,y), x is positive, and y is negative. then if you theoretically rotate it, since you are rotating it 90 degrees, 3 times, you will have to switch the x and y, since 3 is an odd number. so the final answer is (4,-3).

Answer:

(4, -3)

Step-by-step explanation:

270° clockwise = (360-270) = 90° counterclockwise

When rotating 90° counterclockwise (x, y)----> (-y, x)

(-3, -4) ---> (-(-4)), -3) =(4, -3)

Answer: 18.7

Step-by-step explanation:

Find the lengths of AB, BC, and CA

AB = $\sqrt{(4-(-1))^{2} + (-1-4)^{2} }$ = 5 $\sqrt{2}$ ≈ 7.1

BC = $\sqrt{(0-(-1))^{2} + (-3-4)^{2} }$ = 5 $\sqrt{2}$ ≈ 7.1

CA = $\sqrt{(0-4)^{2} + (-3-(-1))^{2} }$ = 2 $\sqrt{5}$ ≈ 4.5

7.1 + 7.1 + 4.5 = 18.7

____ [38]

Answer:

A- l-0.13l

Step-by-step explanation:

l-0.14l is the same as 0.14

l0.13l is the same as 0.13

l-0.18l is the same as 0.18

l-0.2l is the same as 0.2

l14l is the same as 14

The only value that is less that 0.14 is 0.13, making A the correct answer.
