Answer:
A(n) = 5.1×n + 4.5
Step-by-step explanation:
A(n) = A(n-1) + 5.1
A(1) = 9.6
A(n) - A(n-1) = 5.1 ,where n ≥ 1
This means that (A(n)) is an arithmetic sequence where :
<u>The common difference</u> r = 5.1
and
<u>The first term</u> A(1) = 9.6
Therefore
A(n) = A(1) + (n - 1)×r
= 9.6 + (n - 1)×5.1
= 9.6 + 5.1×n - 5.1
= 5.1×n + (9.6 - 5.1)
= 5.1×n + 4.5

Answer:
4, It is the height of triangle ABC
Step-by-step explanation:
The easy way is to just count. But you can also use the Pythagorean theorem because BDC is a right triangle. First, use the distance formula to find BC.
=5
5^2=BD^2+DC^2
25=BD^2+9
BD=4
One and three eighths. Or eleven eighths.
