Answer:
1) The stars are not constant in their position.
2) No. The stars aren't in original position because of apparent movement of stars in the sky.
3) Due to rotation of earth on its axis , the stars appear to move from west to east in the sky. Actually stars don't move as they are constant in their position but they appear to move with respect to earth.
4) Both the motion of stars & motion of sun are similar because both are an example of apparent motion. Both appear to change their respective positions but in reality , sun & stars are constant in their positions. But as earth is rotating , it appears like sun & stars are changing their positions.

Answer:
(1, -3)
Step-by-step explanation:
The point P that partitions AB into the ratio m:n is ...
P = (mB +nA)/(m+n)
The point you're looking for is ...
P = (3(3, -9) +2(-2, 6))/(3+2) = (9-4, -27+12)/5 = (5, -15)/5
P = (1, -3)
Answer:
44.64
Step-by-step explanation:
you do the 10 - 2 in parenthesis then you multiply 5.58 by 8 which is what the 10 - 2 would be and boom you have your answer
1. no, because the sides dont have to have the same ratio. similar triangles would have to have equal angles, but that isn't necessary for a right triangle since the only requirement is for one side to equal 90°. that means the other 2 sides could be any angle, as long as they add up to 90°
2. yes, because they have the same number of sides, they will have the same proportions and interior angles, making them similar
12. no
13. yes
Hello,
a(1)=108
a(2)=a(1)/(-2)=-54
a(3)=a(2)/(-2)=a(1)/(-2)²=27
a(4)=a(3)/(-2)=a(1)/((-2)^3)=-27/2
a(n)=a(1)/(-2)^(n-1)=108 *(-1/2)^(n-1) (exponential decreasing)
lim if x->infinite (a(n))=0==> converges
