Answer:
C
Step-by-step explanation:
The explicit formula for a geometric sequence is
= a
where a is the first term and r the common ratio
From the recursive formula
= - 9
The common ratio r = - 9 and with a = 300, then
= 300
→ C
Answer:
155.3 m
Step-by-step explanation:
<u>We have:</u>
θ: is the angle measured from the vertical = 75 °
v = is the speed of the submarine = 10 m/s
t = 1 min
The deep of the front end of the submarine at the end of a 1-minute drive is given by the following ratio:
<u>Where:</u>
d: is the distance traveled by the submarine in 1 minute
x: is the deep to find
The distance, d, is:
Now, the deep is:
Therefore, the deep of the front end of the submarine at the end of a 1-minute drive is 155.3 m.

Answer:
Step-by-step explanation:
To do this you would simplify both sides.
For the first one:
(subtract 3 from both sides)
(divide 7 from both sides)
and for the second one:
(add 3 to both sides)
(divide 2 from both sides)
When you graph these they will look like these pictures
