the table shows the relationship between the number of

tickets and the total cost to purchase tickets.

write a function to represent the relationship.

$12.25

$16.00

$18.50

$26.00

Step-by-step explanation:

Given:

The relation between the number of tickets and total cost for purchasing them.

Let represent number of tickets and represent the total cost to purchase them.

Now, let the relation be given by the following function:

, where, and are constants.

Let us find and using the values from the table.

For, . So,

For, . So,

Subtract equation 1 from equation 2. This gives,

Now, plug in in equation 1 and solve for .

Therefore, the function to represent the relationship between the tickets and total cost is given as:

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
