Answer:
slope=4root5
Step-by-step explanation:
H^2=b^2+ h^2
(8)^ +(4)^
= 64+16
H^ =80
H= ROOT 80
root(4*4*5)
=4root(5)
Answer:
16

The explicit rule for given sequence is:

Further explanation:
We have to determine first of all if the sequence is arithmetic or geometric.
- If the difference of two consecutive terms is same then the sequence is arithmetic sequence
- If the ratio of two consecutive terms is same then the sequence is geometric sequence
Given sequence is:
12,22,32,42

The common difference is 10 which is same for all consecutive terms. So the sequence is an arithmetic sequence.
The general formula for arithmetic sequence is:

Putting the values of a1 and d
