Answer:
All the answers are correct
Step-by-step explanation:
Any relation that is a function will pass the vertical line test, regardless of any other characteristic it may have (such as being the inverse of some other function).
The inverse of a function is that function reflected across the line y=x. If the inverse passes the vertical line test (is a function), then the original must pass the horizontal line test. The reflection of a vertical line is a horizontal line and vice versa.
Pythagorean theorem: a2 + b2 = c2
(5)^2 + b2 = (6)^2
25 + b2 = 36
-25. -25
b2 = 11
square root both sides to cancel out
and then label the missing side on the triangle = √11
and then point to the theta symbol and find sin, cos, tan, csc, sec, and cot
for example: sin (opposite/hypotenuse) = √11 /6

The trick to this question is the find the least common multiple of 20 and 15. You could do 20×3=60 and 15×4=60 as those both equal the same number yet you there are no other multiples they share before 60. So the next time the two schools will eat pizza on the same day again will be in 60 days. Hope this helps!
7.85 is the approximate answer. (If pi is 3.14)
