Answer:
c=3d
Step-by-step explanation:
What equation models the data in the table if d = number of days and c = cost? Days Cost 2 6 3 9 5 15 6 18
Answer: An equation is a statement used to show the relationship between variables and shows the equality between two expressions. We want to find the relationship between the number of days and the cost.
Given that:
Days Cost
2 6
3 9
5 15
6 18
Lets take the ratio of days to cost using the first row:
The relationship c = 3d is true for all values of days and cost

Answer: The projectile reaches its maximum height after 20 seconds.
Step-by-step explanation:
Given the function:
You can following formula (which gives the x -coordinate of the vertex of the parabola) in order to find after how many seconds the projectile takes to reach its maximum height:
In this case you can identify that the values of "a" and "b" are:
Then, substituting values into the formula, you get the following result:
Therefore,based on this, the conclusion is: The projectile reaches its maximum height after 20 seconds.
