Answer:
Choice A
Period = 4
Amplitude=2
Step-by-step explanation:
From the graph you can see that the graph of the function periodically repeats ecah 4 units. This means that the period of the function is T=4.
The range of the function is [-4,0]. The midpoint of the range is y=-2. When you draw the line =-2, you can see that the graph is 2 units above the line y=-2 and 2 units below the line y=-2. This means that the amplitude is 2.
Answer:
The maximum width must be
Step-by-step explanation:
Let
L ----> the length of the rectangular pool
W ---> The width of the rectangular pool
we know that
so
----> inequality A
we have
substitute the value of L in the inequality A
simplify
The maximum width must be
3 + (-4) = -1, because -1 is 4 units to the left of 3
Answer:
∠1 = 180° - 123° = 57°
∠2 = 180° - 57° - 48° = 75°
∠3 = 180° - 123° - 13° = 44°
