(a)

Answer to Problem 3P
Area of the triangle is 288 square inches
Explanation of Solution
Given information: The height of the triangle is 4 inch more than twice the base of the triangle.
Length of the base is 16 in.
Identify the function rule: The function rule to find the area of the triangle.
Let ‘b’ be the base of the triangle
Height of the triangle is 4 inch more than twice the base of the triangle
Area of the triangle ‘A’ is
Evaluate:
Base of the triangle is 16 in. Substitute 16 for ‘b’
Area of the triangle is 288 square inches
(b)
To graph: Graph the function that is used to find the area of the triangle.
(b)

Answer to Problem 3P
Function rule is not linear
Explanation of Solution
Given information: Function rule to find area of the triangle
Graph: Graph the function rule using the table. Assume some numbers for b and find the area
Base(b) | Area(A) |
0 | 0 |
4 | 24 |
5 | 35 |
Plot the coordinate on the graph
The graph is a curve. The graph is not a straight line. So , it is not linear
The rule is non linear.

- 3. A scientist recorded the movement of a pendulum for 10 s. The scientist began recording when the pendulum was at its resting position. The pendulum then moved right (positive displacement) and left (negative displacement) several times. The pendulum took 4 s to swing to the right and the left and then return to its resting position. The pendulum's furthest distance to either side was 6 in. Graph the function that represents the pendulum's displacement as a function of time. Answer: f(t) (a) Write an equation to represent the displacement of the pendulum as a function of time. (b) Graph the function. 10 9 8 7 6 5 4 3 2 1 0 t 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 -1 -5. -6 -7 -8 -9 -10-arrow_forwardA power outage occurs 6 min after the ride started. Passengers must wait for their cage to be manually cranked into the lowest position in order to exit the ride. Sine function model: h = −82.5 cos (3πt) + 97.5 where h is the height of the last passenger above the ground measured in feet and t is the time of operation of the ride in minutes. (a) What is the height of the last passenger at the moment of the power outage? Verify your answer by evaluating the sine function model. (b) Will the last passenger to board the ride need to wait in order to exit the ride? Explain.arrow_forwardThe Colossus Ferris wheel debuted at the 1984 New Orleans World's Fair. The ride is 180 ft tall, and passengers board the ride at an initial height of 15 ft above the ground. The height above ground, h, of a passenger on the ride is a periodic function of time, t. The graph displays the height above ground of the last passenger to board over the course of the 15 min ride.
