Step-by-step explanation:
Let represent number of tickets and
represent the total cost to purchase them.
Now,assuming the relation to be of the form:
, 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 relation between the number of tickets and total cost of purchase is given as:
The solution set for the last equation represents the set of all days when the towns have the same average high temperature.
- The hotness of matter or radiation is expressed by the physical quantity known as temperature. The average air temperature for a specific time period, often a day, a month, or a year, as measured by a thermometer that has been properly exposed.
- P(t) is the average high temperature, in degrees Celsius, of Paityn's town on t days.
- V(t) is the average high temperature, in degrees Celsius, of Vince's town on t days.
- So, P(t) = V(t) represents the set of all the days when both towns have the same average high temperature.
