Answer:
5
5Step-by-step explanation:
If you use the distance formula you can solve it pretty easily. The distance formula is:
d = 
The two points you want are A and D. A is (-1, -4) and D is (3, -1). Plug that into the formula...
d = 
d = 
d = 
d = 
5
I can solve it in a different way if you want me to.
Sin 2 x + sin x = 0
( sin 2 x = 2 sin x cos x )
2 sin x cos x + sin x = 0
sin x ( 2 cos x + 1 ) = 0
sin x = 0
x 1 = 0
x 2 = π
or: 2 cos x + 1 = 0
2 cos x = - 1
cos x = -1/2
x 3 = 2π/3
x 4 = 4π/3
Answer:
B'(1,4)
Step-by-step explanation:
after reflection in line c....line c is perpendicular bisector of B' and B
find the slope line between trough B and B' its _1 hence slope of the perpendicular bisector should be 1... equation of line c is
