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
If you plug that into a calculator you get 4.5
Answer:
Step-by-step explanation:
Segment
A segment is a line that has 2 end points. We can measure the segment length. A segment is represented by where A and b are the two end points of the segment.
Ray
A ray is an line that has one end point and one point goes in infinity. We cannot measure ray as it's one end goes to infinity. A ray is represented by where A is the end point and B is the infinite point.
Figures of ray and segment are attached.
Answer:
Yes
Step-by-step explanation:
Length of the third side
The hypotenuse is always the longest side of a right triangle.
So, the hypotenuse here is
The Pythagoras theorem applies so the fence does form a right triangle.
