Step-by-step explanation:
One way to get a sense of the graph is to pick integers and make a table of function values.
- x = -3 y = |-3| = 3 Point (-3, 3)
- x = -2 y = |-2| = 2 (-2, 2)
- x = -1 y = |-1| = 1 (-1, 1)
- x = 0 y = |0| = 0 (0, 0)
- x = 1 y = |1| = 1 (1, 1)
- x = 2 y = |2| = 2 (2, 2)
Answer:
0.75 feet per second.
Step-by-step explanation:
Please find the attachment.
We have been given that a 25-ft ladder is leaning against a wall. We can see from the attachment that ladder forms a right triangle with respect to wall and ground.
So we can set a Pythagoras theorem as:
Now, we need to find the derivative of above equation with respect to time.
Since the adder is moving toward the wall at a rate of 1 ft/sec for 5 sec, so x after 5 seconds would be:
Let us solve for y using Pythagoras theorem.
Take positive square root:
Upon substituting our given values in derivative equation, we will get:
Therefore, the ladder is moving up at a rate of 0.75 feet per second.
