Sinx = opps/hyp = 1/2
2^2 = 1^2 + x^2
x = sqrt(3) = adj
Cosx = adj/hyp = sqrt(3)/2
Hey there! :D
Plug in the points to see if they work.
y=7x
(2,14) -> (x,y)
14=7*2
14=14
That works.
(0,0)
0=7*0
0=0
That works
(1,7)
7=7*1
7=7
That works.
The points that work are (2,14), (0,0), and (1,7)
I hope this helps!

Answer:
116 mg
Step-by-step explanation:
From the statement we have that a patient receives 1 1/3 mg of medicine per kilogram of his weight.
The first thing is to pass the mixed number 1 1/3 to a rational number, like this:
1 + 1/3 = 1.33
So it would be 1.33 mg of medicine per kg, if the patient weighs 87 kg, he should be given a total of:
1.33 * 87 = 116
A total of 116 mg should be given to that patient.
It would be choice b.
The domain is the range of x values which in this case is from -5 to 3.
