He made a mistake in step #2. It seemed to be a trivial mistake because it involved signs, but it still had a great impact. Since step#2, his solution was already wrong.
Instead of
(-1)²-4(2)(-6) = 1 + 48 = 49
What he did is
(-1)²-4(2)(-6) = -1 + 48 = 47

Answer:
just distibute the propertys to other propertys
Step-by-step explanation
A
this is a geometric sequence since there exists a common ratio r between the terms
r = = = = 3
B
to obtain the next term in the sequence multiply the previous term by 3
= 3 ← recursive rule
C
the n th term of a geometric sequence is
=
where is the first term in the sequence
= 7 × ← explicit rule
Answer:
75.00
Step-by-step explanation:
1500*0.05
