|
Answer» ong>Answer: Answer: First term = 1 Common difference = 6 Given statements about the terms of an AP: 9th term = 7 × 2nd Term 9th term = 7 × 2nd Term12th term = 5 × 3rd term + 2 We have to find the following: First term, a Common difference, d The standard form of an AP is: a , a + d, a + 2d , a + 3d, ... , a + (n - 1)d Where, a = first term of AP d = common difference of AP So, ACCORDING to the formula, aₙ = a + (n - 1)d We have 9th term and 2nd term as a + 8d and a + d respectively. So According to the statement given, ⇒ 9th term = 7 × 2nd term ⇒ a + 8d = 7 (a + d) ⇒ a + 8d = 7a + 7d ⇒ 7a - a + 7d - 8d = 0 ⇒ 6a - d = 0 ...(i) Similarly, According to the SECOND statement, we have ⇒ 12th term = ( 5 × 3rd term ) + 2 ⇒ a + 11d = { 5(a + 2d) } + 2 ⇒ a + 11d = 5a + 10d + 2 ⇒ 5a - a + 10d - 11d = -2 ⇒ 4A - d = -2 ...(ii) SUBTRACT eq.(ii) from eq.(i), we get ⇒ 6a - d - (4a - d) = 0 - (-2) ⇒ 6a - d - 4a + d = 2 ⇒ 6a - 4a = 2 ⇒ 2a = 2 ⇒ a = 1 We found the first term to be 1, Hence SUBSTITUTE the value of a in eq.(i), we get ⇒ 6a - d = 0 ⇒ 6(1) - d = 0 ⇒ 6 - d = 0 ⇒ d = 6 |

A plant grows in height by 33.33%in six months. If the plant is 180 cm now, what is the height of a plant after one year? |
|
Answer» ong>Given, Plant grows 33.33% in 6 months. Present height of plant = 180 cm To FIND, Height of plant after one year. Solution, We can simply SOLVE this mathematical problem by using the following mathematical process. The TOTAL time period = 1 year = 12 months = 2 × 6 months Height of the plant after first 6 months = 180 + (180 × 33.33/100) = 239.994 cm Height of the plant after last 6 months = 239.994 + (239.994 × 33.33/100) = 319.984 cm Hence, the height of the plant after one year will be APPROXIMATELY 319.984 cm. |

Answer» ong>Answer: x =85° , y = 95° , z = 50° Step-by-step explanation: Given : ray E is parallel to ray F , ∠1 = 90° , ∠2 = 35° To find : ∠x , ∠y , ∠z Solution :- ∠1 = ∠DCA = 95° [ALTERNATE interior angles] ∠DCF = ∠Y [VERTICALLY opposite angles] ⇒ ∠y = 95° Similarly, ∠x + y = 180° [Supplementary angles] ⇒ ∠x = 85° Now, in ΔABC : ∠2 + ∠x + ∠z = 180° [Angle sum property of a triangle] ⇒ 35° + 85° + ∠z = 180° ⇒ ∠z = 180° - 120° ⇒ ∠z = 50° Hope it Helps : CONSIDER marking as the BRAINLIEST? |
