So number six the ratio is(3,3) I think and is Non-proportional
The answer is 3.5 inches for K12 test
All i did was see what coud make 49 feet.
since 1 inch = 14 feet then i did 3 x 14 which got 42.
I then just shuffled around numbers and got 3.5.
THE ANSWER IS 3.5
Very sorry if its wrong
It is more convinient to use substitution
Answer:
-4/9
Step-by-step explanation:
-4/9
This is done through the use of the unit circle.
Your first step is to convert the angle 11π / 2 to an angle between 0 and 2π, which is the range of angles on the unit circle.
This can be done by splitting the circle into sections of π / 2 and counting up 11 sections, or by simply recognizing the fact that 12π / 2 is the same as 6π, which is also the same as 2π. Therefore, we can conclude that 11π / 2 (π / 2 less) is the same angle as 3π / 2.
So we are really finding sin (3π / 2), which is -1 (the y-value of the coordinate at the angle 3π / 2).
