An=a1(r)^(n-1)
a1=first term
r=common ratio
so
firs term is -1
each is double the prevoius
r=2
an=-1(2)^n-1
8th term
a8=-1(2)^(8-1)
a8=-1(2)^7
a8=-1(128)
a8=-128
the 8th term is -128
The correct answer to this question is 9. This can be worked out due to
the fact that 1/10 of 900 is 90, so to reach 90 you have to times 9 by
10.
Answer:
h=15,7 ft
l1=19.8
l2=l1=19.8
Step-by-step explanation:
A=(b×h)/2
110=x×14/2
x×14=220
x=220/14=15,7
h=15.7 ft
l=rad(144+246.7)=19,8
l1=l2=19,8
It is a function, because it has the shape of an x^2 function.
