Answer 1

Answer:

A = Rs 4720 R = 12% p. a T = 1 ½ years = 3/2 years Recall the formula, A = P[1 + (TR/100)] = 4720[ 1 + (3 × 12)/200] = 6419.20 Hence the cost of the cow is Rs 6419.20

hope it helps you

Answer 2

lets start

as you know that sin^2(89)•= cos^2(1)•

sin^2(1)• +cos^2(1)•=1 so we will get total 22 times 1 and sin^2(45)•

22+1/2=22(1/2) will be your answer.

Thank you
