Answer:
A, C
Step-by-step explanation:
For a point to be on the unit circle, it must be a solution to ...
x² +y² = 1
__
The sums of squares of the x- and y-values are ...
A: 1² +1² = 2 . . . <u>not on the circle</u>
B: (-2/3)² +(√5/3)² = (4+5)/9 = 1
C: (√3/2)² +(-1/3)² = 3/4 +1/9 = 31/36 . . . <u>not on the circle</u>
D: 0.8² +(-0.6)² = .64 +.36 = 1
Points A and C do not lie on a unit circle.

Answer:
x = -1
Step-by-step explanation:
since the 23 is positive you have to subtract it on both sides . which would give you -4x =4
then divide -4 on each side and you should get x = -1
a positive divided by a negative is always negative.
<span>The waterbed is 7 x 4 x 1 ft, which is equal to 28 cubic ft (ft3).
The weight is (62.4 lb) per (1 cubic foot). Since the total volume is 28 cubic feet, you multiply 62.4 pounds x 28 ft3.
62.4 x 28 = 1747.2 lbs
The total weight is 1747.2 lbs</span>
Well the fraction would be 325/1000 and the reduced form is 13/40
