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

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.

for DET. 7/3 5/3 is 6

for det 3/2 1/3 is 4

Step-by-step explanation:

for FIRST determinant det.7/3 5/3

we will multiply 7 and 3 ( which is at the BASE of 5)= 7×3=21

and then we will multiply 5 and 3 ( which is at the base of 7)= 5×3=15

then we will substract first TERM from the second=>21-15 = 6

so the determinant of 7/3 5/3 is 6

for second determinant det.3/2 1/2

we will multiply 3 and 2 ( which is at the base of 1)= 3×2=6

and then multiply 1 and 2 ( which is at the base of 3) =1×2= 2

then we will substrat first term with second => 6-2=4

so the determinant of 3/2 1/2 is four.

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°
