Answer:
The required range of the function is [-7,-1]
Step-by-step explanation:
Given : Function
To find : What is the range of the given function?
Solution :
The range is defined as the variation in which any function is defined.
We know that the sin function lies between [-1,1]
.....(1)
The required function is
Multiply equation (1) by -3
.....(2)
Now, we subtract equation (2) by 4
Therefore, The required range of the function is [-7,-1].
Answer:
Number of student tickets were sold = 409
Step-by-step explanation:
Total number of tickets sold = 771
I.e Students ticket (S) + Non students ticket(N S) = 771
Total amount to be paid for tickets = $ 3037
Amount paid by students per tickets = $3
Amount paid by non-students per tickets = $5
So, according to question
S + NS = 771
3 S + 5 NS = 3037
Solve both equations
5 S + 5 NS = 771 × 5
3 S + 5 NS = 3037
so ,
(5 S + 5 NS) - (3 S + 5 NS ) = 3855 - 3037
Or, 2 S = 818
I.e S = = 409
Hence, The number of student tickets were sold = 409 Answer
