Answer:
4. Thank you!
Step-by-step explanation:
Answer:
Because of the range of the sine function.
Step-by-step explanation:
The reason why the value of the sine ratio for an acute angle
of a right triangle must always be a positive value less
than 1 has to do with the the range of the sine function.
The range of the sine function is

But in the first quadrant all y-values are positive and acute angles are less than 90°.
Therefore the range will now be 0≤y<1 for acute angles.
The answer is y=x+2 because you can put it into point slope form
y-4=1(x-2)simplify
y-4=x-2
y=x+2
Answer:

Step-by-step explanation:
We know that a rational number cannot have roots. All of the answer choices cannot be simplified except for
, which can become 1. Therefore, our answer is
.
