    What is the value of Arccot(0)

    Correct Answer
    A.
    Explanation
    The value of Arccot(0) is equal to π/2. This is because the arccotangent function returns the angle whose cotangent is equal to the given value. Since the cotangent of π/2 is 0, the arccotangent of 0 is π/2.

    What is the value of Arcsin 0?

    Correct Answer
    A. 0
    Explanation
    The value of Arcsin 0 is 0 because the arcsine function returns the angle whose sine is equal to the given value. Since the sine of 0 is 0, the arcsine of 0 is also 0.

    What is the value of Arccos(-1)

    Correct Answer
    A.
    Explanation
    The value of Arccos(-1) is 180 degrees or π radians. This is because Arccos is the inverse function of cosine, and cosine of 180 degrees or π radians is equal to -1.

     What is the value of Arccos0

    Correct Answer
    A.
    Explanation
    The value of Arccos0 is 90 degrees or π/2 radians. This is because the arccosine function gives the angle whose cosine is equal to the given value. In this case, the cosine of 90 degrees is 0, so the arccosine of 0 is 90 degrees.

    • 5

    • 25

    • 125

    • 625

    Correct Answer
    A. 125
    Explanation
    The pattern in the given sequence is that each number is obtained by multiplying the previous number by 5. Starting with 5, we have 5 * 5 = 25, 25 * 5 = 125, and 125 * 5 = 625. Therefore, the missing number in the sequence is 125.

    • X can be any real number

    • X can be any positive real number

    • X can be any nonnegative real number

    • X can be any positive integer

    Correct Answer
    A. X can be any positive real number
    Explanation
    The given answer states that x can be any positive real number. This means that x can take on any value that is both positive and a real number. It includes all positive integers as well as any positive fraction or decimal. The answer does not include any negative numbers or zero, as those are not considered positive.
