Correct Answer is “II and IV”

The signs of and y are opposite in each of these quadrants, meeting the requirement you stated. As a result, Quadrants II and IV contain points with and y having opposite signs.

CORRECT ANSWER (D)

To find the number of ways the letters of the word “chord” can be arranged taken all at a time, we use the concept of permutations.

The word “chord” has 5 distinct letters. When arranging all these letters, we have 5 choices for the first position, 4 choices for the second position (since one letter has been used), 3 choices for the third position, 2 choices for the fourth position, and only 1 choice for the fifth position.

Therefore, the total number of arrangements is:

5×4×3×2×1=5!=1205×4×3×2×1=5!=120

So, the correct answer is not listed among the options provided. It should be:

e) 120 ways

THE RIGHT ANSWER (C)

Assume that n = 3.

= (3+1)3(3-1)/3.2.1

= 4.3.2/3.2.1

= (3+1)/3.2.1(1)

= 4/6

2/3

Every point (x, y) where x <0 and y >0 is in the quadrant:

The nth term in an arithmetic progression (A.P.) is determined by:

a_n = a_1 + (n-1)d

where:

The nth term is a_n.
The first term is a_1, and the common difference is d.

According to this property, the negative of the tangent of the corresponding positive angle equals the tangent of a negative angle.
