first of all we have the 5th term and 2nd term
T5=768 =a*r^4
T2=-12=a*r ^1
make a subject of formula in the both equations
that is a=T2/r and T5/r^4
a=12/r and a=768/r^4
when u equate them u will get
-64=r^3 so r=-4 then to find a that is 1st term
since second term is T2=a*r=12 an r=-4 then
a=12/-4 hence a=-3
In the first 3 days, I think that Juanita will ride 12500? I'm not sure if that is right but I think it is.
Answer:
angle CBE=15 degrees
Step-by-step explanation:
angle ECD is 60 degrees and EC=CD because equilateral triangle
angle DCB is 90 degrees and CB=CD because square
angle ECD +angle DCB= angle ECB
60+90=150=angle ECB
since triangle ECB has legs EC and CB equal in length, then it is an isosceles triangle.
so angles CBB and CBE are equal
angle CBE=(180-150)/2
angle CBE=15 degrees
