Apoint on the unit circle lie on the terminal side of an angle in standard position quadrant iv.

Step-by-step explanation:

The problem is about a vector which is in quadrant IV, that is, its angles if from quadrant I to quadrant IV, this means that such angle is between 180° and 270°, because that's the range of angles placed on quadrant IV.

According to trigonometric function theory, in that quadrant, the cosine function of the angle is positive and the sine function of the angle is negative. This is because in the quadrant IV the independent variable is positive and the dependent variable is negative. The independent variable represents the cosine, and the dependent represents the sine.

Therefore, the complete sentences are

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

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
