Answer:
y = (1/5)x² or y = x²/5
Step-by-step explanation:
We have the function f(x) = ax² and are given that the point (5,5) is on the parabola. We need to find 'a'. f(x) can be replaced with 'y', so we can rewrite the equation as...
y = ax²
We know that when x = 5, y = 5, so we have
5 = a(5²) now simplify...
5 = 25a
5/25 = a
1/5 = a, so our equation becomes
(1/5)x² or x²/5 (the expressions are equal)
Answer:
Total time when cost are equal = 600 minutes
Total cost = 104
Step-by-step explanation:
Given:
Plan A = costs 8 plus an additional 0.16 for each minute
Plan B = costs 20 plus an additional 0.14 for each minute
Find:
Total time when cost are equal
Computation:
Assume total time = x minutes
Plan A = 8 + 0.16x
Plan B = 20 + 0.14x
Plan A = Plan B
8 + 0.16x = 20 + 0.14x
0.02x = 12
x = 600 minutes
Total time when cost are equal = 600 minutes
Total cost = 8 + 0.16x
Total cost = 8 + 0.16(600)
Total cost = 104
Since the limit of f(x) is non-zero, the limit distributes over the quotient and
