    • Quadrant I.

    • Quadrant II.

    • Quadrant III.

    • Quadrant VI.

    Correct Answer
    A. Quadrant III.
    Explanation
    The given answer, Quadrant III, is correct because it is the only option that corresponds to the negative x-axis and the negative y-axis. In Quadrant III, the x-coordinates are negative, while the y-coordinates are also negative. This is the only quadrant where both coordinates are negative, making it the correct answer. Quadrant I corresponds to positive x and y coordinates, Quadrant II corresponds to positive x and negative y coordinates, and Quadrant VI corresponds to negative x and positive y coordinates. Therefore, Quadrant III is the only option that fits the given criteria.

    • 8 / 15

    • 8 / 9

    • 15 / 17

    Correct Answer
    A. 15 / 17
    Explanation
    The answer 15/17 is obtained by dividing the numerator (15) by the denominator (17). This means that out of a total of 17 equal parts, 15 parts are being considered. Therefore, the fraction 15/17 represents the ratio or proportion of the given quantity.

    • II and III only.

    • I and III only.

    • I , II and III.

    Correct Answer
    A. II and III only.
    Explanation
    The given answer states that only options II and III are correct. This means that options I and II are incorrect. The explanation for this answer could be that upon evaluating the options, it is determined that only options II and III fulfill the criteria or conditions given in the question. Options I and II may not meet the requirements or may have incorrect information. However, without the context or details of the question, it is difficult to provide a specific explanation.

    In what quadrants are tangent values positive?

    • I and II only.

    • II and III only.

    • I and III only.

    • I and IV only.

    Correct Answer
    A. I and III only.
    Explanation
    Tangent is defined as the ratio of the length of the side opposite the angle to the length of the adjacent side in a right triangle. In quadrant I, both the opposite and adjacent sides are positive, resulting in a positive tangent value. In quadrant III, the opposite side is negative, but the adjacent side is positive, which also leads to a negative tangent value. Therefore, tangent values are positive in quadrants I and III only.

        Using calculator , what is tan-1 (0.84) in degrees ?

    • 40o

    • 57.1o

    • 32.85o

    • 98o

    Correct Answer
    A. 40o
    Explanation
    The correct answer is 40o because the tangent inverse (tan-1) of 0.84 in degrees is the angle whose tangent is 0.84. Using a calculator, when we find the inverse tangent of 0.84, we get approximately 40 degrees.

    A triangle has sides of 11.2 cm and 9.2 cm. the measure of the angle between them is 73°. What is the area of the triangle?

    • 98.53 cm²

    • 15 cm²

    • 49.3 cm

    • 49.3 cm²

    Correct Answer
    A. 49.3 cm²
    Explanation
    The area of a triangle can be calculated using the formula A = 1/2 * base * height. In this case, the given sides of the triangle are 11.2 cm and 9.2 cm, and the angle between them is 73°. To find the height of the triangle, we can use trigonometry. The height can be calculated as h = sin(73°) * 9.2 cm. Then, we can substitute the values into the formula to find the area: A = 1/2 * 11.2 cm * (sin(73°) * 9.2 cm). Evaluating this expression gives us an area of approximately 49.3 cm².

    • 8

    • - 4

    • 4

    Correct Answer
    A. 4
    Explanation
    The given sequence alternates between subtracting 8 and adding 4. Starting from the first number, we subtract 8 to get the second number, then add 4 to get the third number, and so on. Therefore, the next number in the sequence would be 4.
