Answer: The amplitude is 4.
Step-by-step explanation:
Given the form of the sine function:
Where is the amplitude,
is the period and "k" is the vertical shift of the wave.
You know that, in the sine function given ( ), you can identify the amplitude and the period. These are:
- The amplitude is:
- And the period is:
Therefore, the amplitude of is:
Given:
A number line from -10 to 10 with 20 tick marks.
Point D is 1 tick mark to the left of 5.
To find:
The integer value that represents point D.
Solution:
A number line from -10 to 10 with 20 tick marks. It means, each mark represents the integer values from -10 to 10.
We know that, as we move towards left on a number line the value decreases and as we move towards right the value increases.
Point D is 1 tick mark to the left of 5. It means, point D represents the integer value which is 1 less than 5.
Therefore, point D represents the integer 4.
