a.
To determine from the graph whether the car is moving for the interval
a.

Answer to Problem 41PFA
False
Explanation of Solution
Given:
Graph:
From the graph it can be observed that the car is moving from
Therefore, the interval for which the car is moving is
Conclusion:
Therefore, the given statement is false.
b.
To determine from the graph whether the car maintains a constant speed for the interval
b.

Answer to Problem 41PFA
True
Explanation of Solution
Given:
Graph:
Calculation:
From the graph it can be observed that the speed of the car is
Therefore, the interval for which the car has constant speed is
Conclusion:
Therefore, the given statement is true.
c.
To determine from the graph whether the car started with the speed
c.

Answer to Problem 41PFA
False
Explanation of Solution
Given:
Graph:
Calculation:
From the graph it can be observed that the speed of the car when the car starts is
Therefore, the car did not start with 0mi/h.
Conclusion:
Therefore, the given statement is false.
d.
To determine when the car stops.
d.

Answer to Problem 41PFA
True
Explanation of Solution
Given:
Graph:
The car will stop when the speed of the car becomes 0mi/h.
Therefore, it can be observed from the graph that the speed of the car is 0mi/h after
Conclusion:
Therefore, the given statement is true.
e.
To determine whether the car stop from 2 to 4 minutes.
e.

Answer to Problem 41PFA
False
Explanation of Solution
Given:
Graph:
Concept used:
The car will stop when the speed of the car becomes 0mi/h.
From the graph it can be observed that the speed of the car in the interval
Therefore, the car did not stop in the interval
Conclusion:
Therefore, the given statement is false.

- Patterns in Floor Tiling A square floor is to be tiled with square tiles as shown. There are blue tiles on the main diagonals and red tiles everywhere else. In all cases, both blue and red tiles must be used. and the two diagonals must have a common blue tile at the center of the floor. If 81 blue tiles will be used, how many red tiles will be needed?arrow_forwardFind the values of n, if the points (n + 1, 2n), (3n, 2n + 3) and (5n + 1,5n) are collinear.

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?
