Is this some type of trick question I'm missing out on?
Company A: y = 50x + 15
Company B: y = 130x + 55
Set the equations equal to each other and solve for x (number of weeks).
50x + 15 = 130x + 55
Subtract 50x from both sides:
15 = 80x + 55
Subtract 55 from both sides:
-40 = 80x
Did you have a typo? The companies will never have the same cost because company B costs so much more and weeks cannot be negative.
Answer: A) 1/2
Step-by-step explanation:
In a geometric sequence, the consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as
Tn = ar^(n - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
If the third term is 20, it means that
T3 = 20 = ar^(3 - 1)
20 = ar²- - - - - - - - - - 1
If the third term is 20, it means that
T5 = 5 = ar^(5 - 1)
5 = ar⁴- - - - - - - - - - 2
Dividing equation 2 by equation 1, it becomes
5/20 = r⁴/r²
1/4 = r^(4 - 2)
(1/2)² = r²
r = 1/2
