One way the consumer price index (CPI) differs from the GDP chain price index is that the CPI: excludes goods and services purchased by businesses. uses current year quantities of goods and services. includes separate market baskets of goods and services for both base and current years. is bias free.

(3) If the area of the circumcircle of \( \triangle A B C \) is \( 36 \pi \mathrm{~cm}^{2} \) and \( m(\angle A)=37^{\circ} \), then find \( a \).

B) \( \frac{y-1}{3}-\frac{2 y+7}{6}=y+\frac{1-3 y}{2} \) \( \frac{1}{4}(\omega+4)-7=(1-\omega) \frac{1}{7}+\frac{\omega-23}{4} \)

2. Two masses, \( A=2.0 \mathrm{~kg} \) and \( B=4.0 \mathrm{~kg} \), slide along an air track without friction. Initially, \( A \) is located at \( x=0.0 \mathrm{~m} \), and has a velocity of \( 12 \mathrm{~m} / \mathrm{s} \) in the \( +x \) direction, and \( B \) is located at \( x= \) 1.0 m and is at rest. After they collide, both masses move together. A) Use conservation of linear momentum to calculate the common velocity of the two- mass system after the collision. B) How much kinetic energy was lost due to this collision?
