Answer:
about 4312
Step-by-step explanation:
You want the total cost for n CDs to be 3.50n.
The manufacturer will charge you 9700+1.25n, so you want these to be equal:
3.50n = 9700 +1.25n
2.25n = 9700 . . . . . . . . subtract 1.25n
n = 9700/2.25 ≈ 4311.111...
Producing 4312 CDs will make the cost per CD slightly less than $3.50.
____
Producing 4311 CDs will make the cost per CD be about $3.500058. Producing 4312 CDs will bring it down to $3.499536.
Answer:
A
Step-by-step explanation:
The explicit formula for a geometric sequence is
f(n) = f(1) 
where f(1) is the first term and r the common ratio
Here f(1) = 64 and r =
=
=
, then
f(n) = 64
→ A
Answer:
x ≈ 61.3
Step-by-step explanation:
Using the Sine rule, that is
=
( cross- multiply )
5.8 × sinx = 6 × sin58° ( divide both sides by 5.8 )
sin x =
≈ 0.87729, thus
x =
(0.87729) ≈ 61.3
