a.

Answer to Problem 11STP
The scatter plot shows the negative relationship.
Explanation of Solution
Given information:
The scatter plot is mentioned in the problem.
Formula:
If the value at x axis increases and at the same time value at y axis decreases then graph shows negative relationship.
Consider the scatter plot as mentioned in the problem.
Recall that if the value at x axis increases and at the same time value at y axis decreases then graph shows negative relationship.
Since the x axis represents the car’s age and y axis represents the value of car.
Here as the age of car is increases the value of car decreases as in the scatter plot.
Therefore the scatter plot shows negative relationship.
b.
To explain: The conclusion about value of car and the car’s age.
b.

Answer to Problem 11STP
As the car’s age is increases the value of car decreases that is scatter plot shows negative outcome.
Explanation of Solution
Given information:
The scatter plot is mentioned in the problem which shows the value of car and the car’s age.
Formula:
If the value at x axis increases and at the same time value at y axis decreases then graph shows negative relationship.
Calculation:
Consider the statement the scatter plot is mentioned in the problem which shows the value of car and the car’s age.
Recall that if the value at x axis increases and at the same time value at y axis decreases then graph shows negative relationship.
As we observed in the problem that when the age of car is increasing then at the same time the value of car is decreasing.
Therefore we come to the conclusion that as the car’s age is increases the value of car decreases that is scatter plot shows negative outcome.
c.
To explain: Worth of car after 5 years. .
c.

Answer to Problem 11STP
Worth of a car after 5 years will be
Explanation of Solution
Given information:
The y axis represents the value of car and x axis represents the age of car.
Formula:
Consider the statement the y axis represents the value of car and x axis represents the age of car.
Recall that
Therefore after
Therefore I expect the car worth will be

- 9:41 … 93 Applying an Exponential Function to Newton's Law of Cooling 60. Water in a water heater is originally Aa ← 122°F. The water heater is shut off and the water cools to the temperature of the surrounding air, which is 60°F. The water cools slowly because of the insulation inside the heater, and the value of k is measured as 0.00351. a. Write a function that models the temperature T (t) (in °F) of the water t hours after the water heater is shut off. b. What is the temperature of the water 12 hr after the heater is shut off?
