Answer:
1) a1 = -5, a(n) = a(n-1) + 2
Step-by-step explanation:
The explicit formula for an arithmetic sequence can be written ...
an = a1 +d(n -1)
The corresponding recursive formula is ...
a(1) = a1, a(n) = a(n -1) +d
__
Comparing the above explicit formula to the one you're given, you see that ...
a1 = -5, d = 2
Using these values in the recursive formula gives you ...
a(1) = -5, a(n) = a(n-1) +2
$518.5 = $375 + $41x
Now that we have our equation, let's solve for the # of hours
Subtract $375 from both sides
$143.5 = $41x
Divide both sides by $41
3.5 = x
The number of labor hours was 3.5
Answer:
no
Step-by-step explanation:
-8/9÷1/6
To divide by a fraction, multiply by its reciprocal.
- 8/9*6
Cancel common factor of 3
- 1×8/3=2/1
-8/3=2/1
Simplify to get
