Answer:
f(n) = 64(3/4)^(n-1).
Step-by-step explanation:
The common ratio is 48/64 = 36/48 = 3/4.
For a GS nth term = a1 r^(n-1) where r = the common ratio, a1 = the first term, and n = the number of peaks reached.
The axplicit function is 64(3/4)^(n-1).
Part A: What is the solution to the pair of equations represented by p(x) and f(x)? (3 points)
(3,1)
Part B: Write any two solutions for f(x). (3 points)
(0,-5) (1, -3)
Part C: What is the solution to the equation p(x) = g(x)? Justify your answer. (4 points)
(1,3)
because they intersect at that point
Answer:
n = 3.666 or (3 and 2/3)
Step-by-step explanation:
4.5n + 2.5 = 19
4.5n = 19 - 2.5
4.5n = 16.5
n = 16.5 / 4.5
n = 3.666 or (3 and 2/3)
Answer:
15x + 180 ≥ 900
x ≥ 48
Step-by-step explanation:
x = amount of laptops needed to sell.
Equation:
15x + 180 ≥ 900
15x ≥ 720
x ≥ 48
Check:
15(48) + 180 = 900
720 + 180 = 900
900 = 900 (It's good, she needs to make at least 900, so she needs to sell at least 48 laptops).
