Betty was looking at the pythagorean identity: for all real numbers theta,
sin2(theta) + cos2(theta) = 1.
d. suppose additional information is given about the number thetatheta from part (c). you are told that / 2< theta < what are the values of cos(theta) and tan(theta)? explain.

dont think so

step-by-step explanation:

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
