Answer:
see explanation
Step-by-step explanation:
Consider the values of y
, 2, 10, 50
Consider the ratio between consecutive terms
2 ÷ = 5
10 ÷ 2 = 5
50 ÷ 10 = 5
Since the ratio is common then the terms form a geometric sequence
The n th term of a geometric sequence is
= a
where a is the first term and r is the common ratio, hence
= ← explicit formula

Answer:
What is the question I understand the part where you need a ratio as a fraction but, is there a way you can put a pic of the numbers or put the numbers in the question?
Answer:
p(x) = 7x - 20
Step-by-step explanation:
A company makes a profit selling goods when the revenue taken in from the sales is greater than the cost of those goods: p(x) = r(x) - c(x) > 0.
In this case the revenue function is r(x) = 12x; the cost function is c(x) = 5x + 20, and the profit function is p(x) = 12x - (5x + 20), or:
p(x) = 12x - 5x - 20, or
p(x) = 7x - 20
