Answer:
B. graph B
Step-by-step explanation:
The graphs of A,B,C and D are attached below.
Let x represent the credit amount and y represent the minimum amount due.
For a bill of less than $100, the entire amount is due. That is for 0 ≤ x < $100, y = x
For a bill of at least $100 but less than $500, the minimum due is $100. That is for $100 ≤ x < $500, y = 100
For a bill of at least $500 but less than $1,000, the minimum due is $300. That is for $500 ≤ x < $1000, y = $300
For a bill of $1,000 or more, the minimum due is $500. But the credit limit is $2000. That is For $1000 ≤ x < $2000, y = $500
The graph that shows the minimum amount due for a credit amount of x is graph B
Once the rock hits the ground, we know that its height will be equal to 0m
because of this, we can replace H(x) with 0
now all we have to do is get x by itself
so..
then
now take the square root of each side
2.857 seconds (rounded to the third decimal)
