1 Given the demand function q=210p+900 (a) Find the are ulisticity

1 Given the demand function q=210p+900 (a) Find the are ulisticity of demand when p inctests from 10 ta 11 (6) Find the are elasticity of demand when y increaces from 20 to 21 (c) Find the point elasticity of deusand when yn=10 and compere it with the are elasticity. Is denatad elastic on inelastic? Justify your absuer. (d) Fird the point elasticity of demand when p0=20 and compare it with the are elasticity. Is denated elastic on inelastic? Justify your absuer. 2. Calculate the folloning partial derivatives. z=x2y+2ry24xe32 (b) Find dza2,b3,dr22,by22 and 4y2i2 for zyln(3z)4ln(xy) 3.
