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
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
1. pi/2 and 3pi/2 2. f(x)=cotx 3. domain: -inf
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
