The question is kind of confusing but from my understanding, The hypothesis needs to be realistic enough to be put through a trial. Thus if it isn't able to be backed up by some type of existing events then theres no reliable way for them to assume the ou...

1. pi/2 and 3pi/2 2. f(x)=cotx 3. domain: -inf<x<inf, x does not equal pi/2+npi, where n is an integer range: -inf<y<inf 4. f(x)=cotx and f(x)=secx 5. It is true, because the cosine function has a period of 2pi 6. f(x) has no zeros and f(x) has a period o...

1. B (f(x)=4cos(x/2)-3) 2. B,F,G (c=-1; a=2; b=2) 3. C (H(t)=-2.4cos(0.017t)) 4. A,B,E,F (y=cos^-1x; y=cot^-1x; y=sin^-1x; y=tan^-1x) 5. C (y=sin^-1x) 6. C (48.7°) 7. C (f(g(x))=sec(sinx); domain: all real numbers; range: 1 <= x <=1.85 8. C (step 3)

I aint brave enough to use them answers so I'll js post what I got. Waves Unit test btw for honors (24 questions) 1. Light waves do not require a medium to propagate. 2. As a wave's frequency increases, more energy is carried by the wave in a given time p...
