In march of 2009, jennifer bought shares of stock in the pepsi-cola company for $47 per share. in december 2009, she sold them for $60 per share. express the increase in price as a percent of the purchase price. round to the nearest tenth of a percent

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

thats one
