Given:
y = sinx
Required:
To find the range.
Explanation:
The graph of the sine function is as follows:
We can observe from the graph that the values of y lie between -1 to 1.
So the range of the sinx function is [-1, 1].
Final Answer:
The range of sinx function = [-1, 1].
Answer:
x ≤ - 27
Step-by-step explanation:

The inequality is t < 55
<em><u>Solution</u></em><em><u>:</u></em>
Given that, To qualify for the championship a runner must complete the race in less than 55 minutes
Let "t" represent the time in minutes of a runner who qualifies for the championship
Here it is given that the value of t is less than 55 minutes
Therefore, "t" must be less than 55, so that the runner qualifies the championship
<em><u>This is represented by inequality:</u></em>

The above inequality means, that time taken to complete the race must be less than 55 for a runner to qualify
Hence the required inequality is t < 55
