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

Answer:
Whatttttt.
Step-by-step explanation:
Answer:
$40.92
Step-by-step explanation:
child ticket = $4.99 per kid
adult ticket = $5.99
we are told that Jenni has 7 kids she wants to take to the water park. we can multiply 4.99 × 7 to get the total cost of the 7 kids
4.99 × 7 = $34.93
we are also told that Jenni herself wants to go to the water park. since there is only 1 adult going (jenni) we can add $5.99 to our total for the 7 kids
$34.93 + $5.99 = $40.92
it would be $40.92 for Jenni to go to the waterpark with her 7 kids
this problem can also be expressed as an algebraic expression:
4.99x + 5.99 when x = 7
Answer:
- 10.05
Step-by-step explanation:
We have to find the value of using a calculator or a square root table to approximate to the nearest thousandth i.e. approximation up to three decimal places.
Now, using calculator we get the value of
So,
Therefore, approximate to the nearest thousandth is - 10.05 ( Answer )
