Step-by-step explanation:
Tn= a+(n-1)d
= 123 +(70-1)7
=123+(69)7
=123+483

<span>Give 3 complex fractions that simplify to ¼
Complex fractions are bigger fractions that can be simplified into smaller
fractions.</span>
<span>=> First is 15 / 60
15/60 = 1 /4
=> second is 50/200
50/200 = 1 / 4
=> Third is 43/172
43/172 = 1 / 4
There are many possible answer. There are infinite complex fractions that can
be simplified to 1 /4. I only gave 3 examples to show how simplified fraction works.</span>
Answer:
- recursive: a[1] = 7440; a[n+1] = a[n] -120
- explicit: a[n] = 7440 -120(n -1)
Step-by-step explanation:
The sequence of amounts in Jackson's account will be ...
7440, 7320, 7200, ...
with a first value (a1) of 7440 and a common difference (d) of -120.
The recursive formula for an arithmetic sequence is ...
a[1] = a1
a[n+1] = a[n] +d
For our sequence, the recursive formula is ...
a[1] = 7440
a[n+1] = a[n] -120
__
The explicit formula for an arithmetic sequence is ...
an = a1 +d(n -1)
For our sequence, the explicit formula is ...
a[n] = 7440 -120(n -1)
Answer: ↓↓
Step-by-step explanation:
The original value of the cellphone is $650. The function represents an exponential decay because if it was exponential growth, the function would look like this:
