Answer:
This relation is a function.
Step-by-step explanation:
This relation is a function because a there should be no repeating x-coordinates in the relation for it to be a function and that is exactly what happens in this relation.
Answer:
141.5
Step-by-step explanation:
because, x=26.5 and y=4 and then, its just plugining it into the equation Im not sure about the x and y but, I took the test and got it right.
The answer is 16 and 26. Both are less than 30 and greater than 10 and have 6 in the one’s place.
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 =
when you simplify this you get 1/16x^8
