Unformatted text preview: The height of the shorter building=100tan45=100m The difference of the heights between the two buildings=100tan30=57.7m The height of the taller building=100+57.7=157.7m 3. Solve 3x-2x-8=0 in two ways: 1) Factoring the equation 2) Using the formula 1) 3x-2x-8=1 3x +(1 4-3 2)+2 4=(x-2)(3x+4)=0 x=2, -4/3 2) x=(2(2+4 38))/23=(2 10)/6 x=2, -4/3 4. Newtons law of universal gravitation is given by F=GMm/r. Whats the dimension of G? [G]= [F][r]/([M][m]), where F is force, M and m are masses and r is distance. Thus [G]=(MLT)(L)/M=L/(MT)...
