Answer:
18ft
Step-by-step explanation:
6ft -> 4ft shadow
6 = 4m
m = 6/4
y = 12m
y = 12(6/4)
y = 18ft
X = 4/7 = 0.571 I believe so
Answer:
see explanation
Step-by-step explanation:
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
Given
=
and r =
, then
a
=
, that is
= 
=
( cross- multiply )
32a = 2048 ( divide both sides by 32 )
a = 64 ← first term
Thus the explicit formula is
= 64 
The answer is 64 because (2^3) is 8 with an exponent of 2 is 64

now, for the other, we use the same cancellation rule
