Answer:
<h3>The answer is option D</h3>
Step-by-step explanation:
Since the sequence is a geometric sequence
For an nth term in a geometric sequence

where
n is the number of terms
a is the first term
r is the common ratio
To find n we must first find the common ratio
To find the common ratio divide the previous term by the next term
That's
r = 3/1 = 3 or r = 9/3 = 3
a = 1
Substitute the values into the above formula
That's
If n is an integer then


where n is greater than or equal to 2

Answer:
150(.40)^n is your equation
Step-by-step explanation:
The cost per foot of redwood and of pine is $3.5 and $1.5 respectively.
<h3>How to solve simultaneous equation?</h3>
let
- cost of redwood = x
- cost of pine = y
50x + 70y = 280
100x + 60y = 440
Multiply (1) by 2
100x + 140y = 560
100x + 60y = 440
subtract to eliminate x
80y = 120
y = 120/80
y = $1.5
substitute y = 1.5 into (1)
50x + 70y = 280
50x + 70(1.5) = 280
50x + 105 = 280
50x = 280 - 105
50x = 175
x = 175 / 50
x = $3.5
