Divide 71,290 with 2
71,290 / 2 = 35,645
Then, divide 35,645 with 12 ( because theres 12 months in 1 year )
35,645 / 12 = 2970.42
a) 2970.42 is your answer.
Y doesn't vary directly with x
Answer:
a[n] = a[n-1]×(4/3)
a[1] = 1/2
Step-by-step explanation:
The terms of a geometric sequence have an initial term and a common ratio. The common ratio multiplies the previous term to get the next one. That sentence describes the recursive relation.
The general explicit term of a geometric sequence is ...
a[n] = a[1]×r^(n-1) . . . . . where a[1] is the first term and r is the common ratio
Comparing this to the expression you are given, you see that ...
a[1] = 1/2
r = 4/3
(You also see that parenthses are missing around the exponent expression, n-1.)
A recursive rule is defined by two things:
- the starting value(s) for the recursive relation
- the recursive relation relating the next term to previous terms
The definition of a geometric sequence tells you the recursive relation is:
<em>the next term is the previous one multiplied by the common ratio</em>.
In math terms, this looks like
a[n] = a[n-1]×r
Using the value of r from above, this becomes ...
a[n] = a[n-1]×(4/3)
Of course, the starting values are the same for the explicit rule and the recursive rule:
a[1] = 1/2
Answer:
0.5
Step-by-step explanation:
500/1000 = 0.5
0.5 * 1000 = 500
T-Shirts $ More Shop: Final cost = 2m + 12
m = mug
You Say It, We Print It: Final Cost = 5m
If you buy 5 mugs from both place:
2 * 5 = 10
10 + 12 = 22
$22 for T-Shirts & More
5 * 5 = $25
$25 from You Say It, We Print It
D. T-Shirts & More is the better buy if you buy more than 4 mugs.
