Find the first three terms of the A.P. We know that an = a + (n – 1) d So, a4 = a + (4 – 1) d a4 = a + 3d Also, a8 = a + (8 – 1)d a8 = a + 7d Similarly, a6 = a + (6 – 1)d a6 = a + 5d And a10 = a + (10 – 1)d a10 = a + 9d ...

WebGiven: In right triangle ABC, right angled at C, M is the mid-point of hypotenuse AB. C is joined to M and produced to a point D such that DM = CM. Point D is joined to point B. To Prove: (i) ∆AMC ≅ ∆BMD (ii) ∠DBC is a right angle (iii) ∠DBC ≅ ∆ACB (i) In ∆AMC and ∆BMD, AM = BM ∵ M is the mid-point of the hypotenuse AB WebSolution Let the radius of the circle be r cm. Area of the circle = 154 cm 2 ⇒ π r 2 = 154 cm 2 ⇒ 22 7 × r 2 = 154 ⇒ r = 154 × 7 22 = 7 cm ∴ Perimeter of the circle = Circumference of the circle = 2 π r = 2 × 22 7 × 7 = 44 cm If the area of a circle is 154 cm 2, then its perimeter is ___44 cm___.

Web3 feb. 2024 · Two logical formulas p and q are logically equivalent, denoted p ≡ q, (defined in section 2.2) if and only if p ⇔ q is a tautology. We are not saying that p is equal to q. Since p and q represent two different statements, they cannot be the same. What we are saying is, they always produce the same truth value, regardless of the truth values ... WebNamely, P → Q is equivalent to ¬ P or Q, or in symbols, ¬ P ∨ Q. Now we can look at your specific case, using the above approaches. If P is false, ie if x 2 ≠ x is false (so x 2 = x ), … WebTerms in this set (44) a diameter of a circle is a chord. true. if a quadrilateral has two sets of congruent sides, then it is a kite. false. the vertex of ∠CAB is point A. ... if ∠Q ≅ ∠R then … the stardust man appears 1 hour
