True
Note that:
The graph of sine and cosine functions are very similar. They only have a shift in the x -axis.
That is, sin x = cos (90 - x)
Since there is a great similarity between the sine and cosine graphs, and the secant graph is an inverse of the cosine graph, the graph of sine can be used to construct the graph of the secant function
Mathematically:
since sec x = 1 / cos x
and, cos x = sin (90 - x)
therefore, sec x = 1 / sin (90 - x)
The graphs of the sine and secant functions are attached to this solution

a theater has 144 seats. the theater sells tickets for $6 per adult and $4 per child
Let x be the number of adult tickets
and y be the number of child tickets
Total number of tickets sold is 144
x + y = 144 -----------> equation 1
the theater sells tickets for $6 per adult and $4 per child and earned $660
6x + 4y = 660 ----------> equation 2
Solve for x and y
x + y = 144
y = 144 - x
Now plug it in second equation
6x + 4y = 660
6x + 4(144 - x) = 660
6x + 576 -4x = 660 (combine like terms)
2x + 576 = 660 (subtract 576 from both sides)
2x = 84 (divide by 2)
x= 42
Number of adult tickets = 42
y = 144 - x
y = 144- 42= 102
Number of child tickets = 102
B is your answer because if you check each one in the calculator B is the same as the expression and also 2^8 makes up the first part and the second half makes up the .24
Answer:
A discrete function is a function with distinct and separate values. This means that the values of the functions are not connected with each other (this will be shown as a bunch of points that are not connected together).
