Point b has coordinates (4,2). The x-coordinate of point A is -2. The distance between point A and point B is 10 units. What are the possible coordinates of point A
1 answer:
Answer:
point A coordinates are (-2,-6)
Step-by-step explanation:
Point A (-2,y)
point B (4,2)
x_1= -2, y_1= y_1 (unknown)
x_2= 4, y_2=2
distance=10
using the formula for distance between two points;
distance=
10=
10=
square both sides

Answer:
9/10
Step-by-step explanation:
y2-y1÷x2-x1
-18-0/-12-8
-18/-20
9/10
Work is all listed below:
1) -1/6 - 3/6 = -4/6 = -2/3
2) 8/12 - 2/12 = 6/12 = 1/2
3) 4/7 - 1/4 = 16/28 - 7/28 = 9/28
If you look at a unit circle (or you have one memorized, which I would strongly suggest) (√2/2,√2/2) is located at the radian value
, which is 45 degrees
V=(1/3)πr²h ∴ dV/dt =(π/3)[r²(dh/dt)+h2r(dr/dt)] =(π/3)[(30)²(-2)+40(2)(30)(2)] =(π/3)[-1800+4800] =1600π in³/sec Answer: 1600π in³/sec
