Answer:
$21.57
Step-by-step explanation:
4.5 (1.22) + 0.8 (1.70) + 4.6 (3.20) =
5.49 + 1.36 + 14.72
21.57
Answer: 1875
Step-by-step explanation:
The nth term of a geometric progression is given as:
= ar^n-1
Given a = 3 ; r = 5, the nth term will be:
= ar^n-1
= 3 × 5^n-1
The fifth term will be:
= 3 × 5^n-1
= 3 × 5^5-1
= 3 × 5⁴
= 3 × 625
= 1875
The fifth term is 1875
15 kilometers = 15,000 meters
15,000/600 = 25
So there will be a total of 25 water stations.
Answer:
We can predict the vertex point of 
by vectorial sum, which is equal to 
.
Step-by-step explanation:
The vertex of is equal to the vectorial sum of the vertex of 
and the translation vector:
(1)
Where 
is the translation vector.
If we know that 
and 
, then the formula for the vertex of is:
The next three terms are 2, 1/2, 1/4
You take 1/2 of each previous term to get the next term, which means this sequence is geometric (first term is 4, common ratio is 1/2)
