A.

3x\(^2\) +3y\(^2\) + 5x + 7y =5

B.

x\(^2\) + y\(^2\) + 5x + 4y = 0

C.

5x\(^2\) + 5y\(^2\) - 16 = 0

D.

x\(^2\) - y\(^2\) + 3x - 5y = 2

No explanation has been provided for this answer.

137.

In how many ways can the letters of the word MEMBER be arranged?

A.

720

B.

360

C.

180

D.

90

Correct answer is C

No. of ways = \(\frac{6!}{2!2!}\)

= \(\frac{6 \times 5 \times 4 \times 3 \times 2!}{2 \times 1 \times 2!}\)

= 180 ways

138.

Calculate, correct to two decimal places, the area enclosed by the line 3x - 5y + 4 = 0 and the axes.

A.

0.50 square units

B.

0.51 square units

C.

0.53 square units

D.

0.54 square units

Correct answer is C

Area = \(\frac{1}{2} \times 1.33 \times 0.8\)

= 0.53 square unit 

139.

A circle with centre (5,-4) passes through the point (5, 0). Find its equation.

A.

x\(^2\) + y\(^2\) + 10x + 8y + 25 =0

B.

x\(^2\) + y\(^2\) +10x - 8y - 25 = 0

C.

x\(^2\) + y\(^2\) - 10x + 8y + 25 =0

D.

x\(^2\) + y\(^2\) -10x - 8y - 25 = 0

Correct answer is C

(x - h)\(^2\) + (y - k)\(^2\) = r\(^2\)

x\(^2\) - 2hx + y\(^2\) - 2ky + h\(^2\) + k\(^2\) = r\(^2\)

x\(^2\) - 2(3)x + y\(^2\) - 2(-4) y + 5\(^2\) + (-4)\(^2\) = r\(^2\)

x\(^2\) - 10x + y\(^2\) + 8y + 25 + 16 = r\(^2\)

x\(^2\) - 10x + y\(^2\) + 8y + 41 = r\(^2\)

at point (5,0)

5\(^2\) - 10(5) + 0\(^2\) + 8(0) + 41 = r\(^2\) 

25 - 50 + 41 = r\(^2\)

16 = r\(^2\) 

r = \(\sqrt{16}\) 

= 4 

x\(^2\) + y\(^2\) - 10x + 8y + 25 = 0

140.

Find the nth term of the linear sequence (A.P) (5y + 1), ( 2y + 1), (1- y),...

A.

(8 + 3n)y + 1

B.

8y + 3n + 1

C.

(8 - 3n)y + 1

D.

8y - 3n + 1

Correct answer is C

Tn = a + (n - 1)d

Tn = 5y + 1 (n - 1) -3y

Tn = 5y + 1 - 3ny + 3y 

Tn = 8y - 3ny + 1

Tn = (8 - 3n) y + 1
