The cotangent function is defined as the length of the side adjacent over the length of the side opposite.
Step-by-step explanation:
The sine of an angle is defined as the length of the side opposite over the length of the hypotenuse.
The cosine of an angle is defined as the length of the side adjacent over the length of the hypotenuse.
The tangent of an angle is defined as the length of the side opposite over the length of the side adjacent.
The cotangent function is defined as the length of the side adjacent over the length of the side opposite.
The secant of an angle is defined as the length of the hypotenuse over the length of the side adjacent.
The cosecant of an angle is defined as the length of the hypotenuse over the length of the side opposite.
Answer:

Step-by-step explanation:
Rational numbers, expressed as decimal numbers, are obtained from the operation of division between the integer of the numerator and the integer of the denominator. Then:

Answer:
D. The checking account is overdrawn by $15.
Step-by-step explanation:
Since the balance on a checking account represents the remaining money left in that checking account, having a negative value for that would mean an overdrawing of money, or drawing more money than is in that account in the first place.
Therefore, the answer would be that the checking account is overdrawn by $15.
