Question

5. Read the following and answer any four questions from (i) to (o) : A winch machine is used to tow a boat towards the dock by a rope. Winch operator used rope of length I m to tow the boat. Winch machine is x m high above the water level on the dock. The distance between the boat and the foot of the winch machine is twice the height of the winch machine. х y X 1 m (d) 5x m (d) 1 = x2 + (2x) stretched length ? Answer the following referential questions : (1) Length lin terms of x is (a) 13 x m (b) 5 x m (c) V5 x2 m (ii) Pythagorean relation in terms of I and x is (a) = x² + 2x² (b) B = ? x 2x2 (c) P = (x + 2x) (iii) How far is the boat from the dock if the sailor uses the rope of 15 (a) 315 m (b) 675 m (C) 225 m (d) Insufficient information (iv) If the mast of the boat is y m tall and winch is x m high such that y > x then what is the scale factor of two heights describing enlargment ? у x (b) y X (d) y - x (c) xy (a) X (v) If h is the length of the perpendicular drawn from the foot of the winch to the rope such that the rope is divided into two lengths a and b as shown in the figure then which of the following relation is true? a y Х h milarih are por (c) ha = ab (d) h = a? – b2 if a > b (a) h = a² + b2 (b) h2 = (a + b)2 maths ​

Answer 1

Answer:-

Subject-verb agreement refers to the relationship between the subject and predicate of the sentence. Subjects and verbs must always agree in two ways: tense and number. For this post, we are focusing on number, or whether the subject and verb are singular or plural.

Answer 2

(ii) Pythagorean relation in terms of I and x is

(a) = x² + 2x²

(b) B = ? x 2x2

(c) P = (x + 2x)

Answer = c) P = (x + 2x)

(iii) How far is the boat from the dock if the sailor uses the rope of 15

(a) 315 m

(b) 675 m

(c) 225 m

Answer = a) 315 m

(iv) If the mast of the boat is y m tall and winch is x m high such that y > x then what is the scale factor of two heights describing enlargement ?

a) у x

(b) y X

(c) xy

(d) x - y

Answer = c) xy
