Answer:
The value of the bond when Tyler's mom purchased it was $150
Step-by-step explanation:
we know that
In this problem we have a exponential function of the form
where
a is the initial value (y-intercept)
b is the base
r is the rate
b=(1+r)
In this problem
r=4%=4/100=0.04
b=1+0.04=1.04
substitute
where
x is the number of years since the savings bond was purchased
f(x) is the value of the savings bond
For x=1
f(x)=$156
substitute
Solve for a
therefore
The value of the bond when Tyler's mom purchased it was $150
Given:
The recursive formula of a geometric sequence is
To find:
The explicit formula of the given geometric sequence.
Solution:
We know that, first term of geometric sequence is .
Recursive formula of a geometric sequence is
...(i)
where, r is common ratio.
We have,
...(ii)
On comparing (i) and (ii), we get
The explicit formula of a geometric sequence is
Putting and
, we get
Therefore, the correct option is D.
