Why did New York Times call the 1964 World's Fair "a glittering mirror of our national opulence"?

**algebra**

y=ax -11=a(-4) Divide both sides by -4 a=2.75 y=2.75/x ------ this is the first answer y=(2.75)(6) y=16.5 ------- this is the second answer I hope that helps!!!

a) F=ma F-mg sin 24= ma a= 34-[ 5.2(9.81) sin 24]/5.2 a=2.55m/s^2 b) F=ma mg sin 24-Fk=ma (5.2x 9.81x sin 24)- (5.2x 9.81x cos 24)(0.12)= 5.2a 20.75-5.59=5.2a a=2.91m/s^2

list the period, amplitude, interval, and phase shift of: g(t)=5/2sint-pi i know the amplitude is 5/2 but everything else im not getting. the regular formula for these is y=Asin(Bx+C)+D A is the amplitude B is the period which you use (2pi/b) to solve. C is just a constant i a...
