Answer:
Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
7-24-25
7² + 24² = 25²
49 + 576 = 625
625 = 625
9-40-41
9² + 40² = 41²
81 + 1600 = 1681
1681 = 1681
Answer:
Formula: 0.12x = y
Step-by-step explanation:
5 × 0.12 = 0.60
3 × 0.12 = 0.36
14 × 0.12 1.68
The underlying arithmetic progression is
-15, 0, 15, 30, ...
starting with
and with a common difference of
between terms. Recursively, this sequence is given by

So we have



and so on, so that the explicit rule for the sequence is

for
.
The series consists of 15 terms, since

So we have

and the answer would be B.
