<h3>Answer: 32</h3>
==================================================
Work Shown:
Let
x = number of visits
y = total cost in dollars
The membership costs $18 no matter how many visits you do. If you make x visits, at $1 each, then it costs an additional 1*x = 1x = x dollars. This is added on top of the base membership fee. In total, we know that y = 18+x = x+18
We want the total y to be at most $50. Therefore . The highest y can get is 50.
Let's replace y with x+18 and isolate x
y is replaced with x+18
subtract 18 from both sides
This tells us that we can make at most 32 visits. In other words, the maximum number of visits is 32.
Out of the four choices, it would be A
Answer:
Step-by-step explanation:
To do this, we must use the unit circle. At the angle the coordinate pair is (, ) and the hypotenuse is 1
Now that we know these we can start using the trig functions
sin = y
cos = x
tan =
And the other functions would be the reciprocal of these
csc =
sec =
cot =
This would mean that
sinx =
cosx =
tanx = or if you're supposed to rationalize your denominators
cscx = 2
secx = or
cot =
