Step-by-step explanation:
Answer:
a = 2 , r = 5
Step-by-step explanation:
The n th term of a geometric progression is
= a![r^{n-1}](https://tex.z-dn.net/?f=r%5E%7Bn-1%7D)
where a is the first term and r the common ratio
Given the 4 th term is 250, then
ar³ = 250 → (1)
Given the 7 th term is 31250, then
a
= 31250 → (2)
Dividing the 2 equations gives
=
, that is
r³ = 125 ← take the cube root of both sides
r =
= 5
Substitute r = 5 into (1)
a × 5³ = 250, that is
125a = 250 ( divide both sides by 125 )
a = 2
Plug all three answers in and see which one does not equal 0
A: 2(1)+3(1)-7-12≠0
B: 2(6)+0-0-12=0
C: 2(3)+3(3)-3-12=0
So A. I don't know why it says two (?) points?
<span>The answer to your question is 180 degrees. A reciprocal course means that you turn around in the opposite way in the middle of the outbound course. Turning around in the exact opposite way would be 180 degrees from the starting position.</span>
