Determine two pairs of polar coordinates for the point (4, -4) with 0° ≤ θ < 360°. a) (4√2, 45°), (-4√2, 225°) b) (4√2, 135°), (-4√2, 315°) c) (4√2, 225°), (-4√2, 45°) d) (4√2, 315°), (-4√2, 135°)

The point (4, -4) lies in Quadrant IV. Since we are interested only in positive angles, we choose 315 degrees with a radius (magnitude) of 4√2. That automatically eliminates Answer Choices A, B and C, so all we have to do now is to verify that (-4√2, 135 degrees) also represents (4, -4). It does: Going to Quadrant II with angle 135 degrees, and then using -4√2 as the magnitude, takes us to Quadrant IV.

Thus, D is the correct answer.

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
