Answer» Answer: implify (4x2 – 4x – 7)(X + 3) Here's what the multiplication looks like when it's done HORIZONTALLY: (4x2 – 4x – 7)(x + 3) (4x2 – 4x – 7)(x) + (4x2 – 4x – 7)(3) 4x2(x) – 4x(x) – 7(x) + 4x2(3) – 4x(3) – 7(3) 4x3 – 4x2 – 7x + 12x2 – 12x – 21 4x3 – 4x2 + 12x2 – 7x – 12x – 21 4x3 + 8X2 – 19x – 21 That was painful! Now I'll do it vertically: 4x^2 – 4x – 7 is positioned above x + 3; first row: +3 times –7 is –21, carried down below the +3; +3 times –4x is –12x, carried down below the x; +3 times 4x^2 is +12x^2, carried down to the LEFT of the –12x; second row: x times –7 is –7x, carried down below the –12x; x times –4x is –4x^2, carried down below the +12x^2; x times 4x^2 is 4x^3, carried down to the left of the –4x^2; adding down: 4x^3 + (+12x^2) + (–4x^2) + (–12x) + (–7x) + (–21) = 4x^3 + 8x^2 – 19x – 21 That was a LOT easier!

3/4x(s+2/5)+2s idk.....

Answer»

Answer:

implify (4x2 – 4x – 7)(X + 3)

Here's what the multiplication looks like when it's done HORIZONTALLY:

(4x2 – 4x – 7)(x + 3)

(4x2 – 4x – 7)(x) + (4x2 – 4x – 7)(3)

4x2(x) – 4x(x) – 7(x) + 4x2(3) – 4x(3) – 7(3)

4x3 – 4x2 – 7x + 12x2 – 12x – 21

4x3 – 4x2 + 12x2 – 7x – 12x – 21

4x3 + 8X2 – 19x – 21

That was painful! Now I'll do it vertically:

4x^2 – 4x – 7 is positioned above x + 3; first row: +3 times –7 is –21, carried down below the +3; +3 times –4x is –12x, carried down below the x; +3 times 4x^2 is +12x^2, carried down to the LEFT of the –12x; second row: x times –7 is –7x, carried down below the –12x; x times –4x is –4x^2, carried down below the +12x^2; x times 4x^2 is 4x^3, carried down to the left of the –4x^2; adding down: 4x^3 + (+12x^2) + (–4x^2) + (–12x) + (–7x) + (–21) = 4x^3 + 8x^2 – 19x – 21

That was a LOT easier! But, by either method, the answer is the same:

Answer»

সমাধান

সঠিক প্রশ্ন

রফিকের পিতা এবং রফিকের 5 বছর পূর্বে বয়সের অনুপাত ছিল 10 : 4 এবং 5 বছর পরে রফিকের পিতা। ও রফিকের বয়সের অনুপাত হবে 2 : 1

ক. প্রদত্ত তথ্যের আলােকে দুইটি সমীকরণ গঠন কর

খ. প্রতিস্থাপন পদ্ধতি ব্যবহার করে, তাদের দুইজনের বর্তমান বয়স নির্ণয় কর

গ. ‘ক’ হতে প্রাপ্ত সমীকরণদ্বয় লেখের সাহায্যে সমাধান করে, ‘খ’ এর উত্তরের সত্যতা যাচাই কর

উত্তর

ক. মনে করি 5 বছর পূর্বে

রফিকের পিতার বয়স ছিল x বছর এবং রফিকের বয়স ছিল = y বছর

∴ রফিকের পিতার বর্তমান বয়স ( x + 5 ) বছর

এবং রফিকের বর্তমান বয়স = ( y +5 ) বছর

বলা আছে রফিকের পিতা এবং রফিকের 5 বছর পূর্বে বয়সের অনুপাত ছিল 10 : 4

$\displaystyle \therefore \sf{ \frac{x}{y} = \frac{10}{4} }$

$\implies \displaystyle \sf{ \frac{x}{y} = \frac{5}{2} }$

$\implies \displaystyle \sf{2x = 5y}$

$\implies \displaystyle \sf{2x - 5y = 0} \: \: \: .......(1)$

এখন 5 বছর পরে

রফিকের পিতার বয়স হবে

= ( x + 5 +5 ) বছর = ( x + 10 ) বছর

রফিকের বয়স হবে

= ( y + 5 + 5 ) বছর = ( y + 10 ) বছর

প্রশ্নানুযায়ী

$\displaystyle \therefore \: \: \sf{ \frac{x + 10}{y + 10} = \frac{2}{1} }$

$\implies \displaystyle \: \: \sf{x + 10 = <klux>2Y</klux> + 20}$

$\implies \displaystyle \: \: \sf{x - 2y = 10}$

প্রদত্ত তথ্যের আলােকে সমীকরণ দুইটি হল

$\displaystyle \sf{2x - 5y = 0} \: \: \: .......(1)$

$\displaystyle \: \: \sf{x - 2y = 10} \: \: .......(2)$

খ. প্রতিস্থাপন পদ্ধতি ব্যবহার করে সমাধান

2 নং সমীকরণ থেকে পাই

$\displaystyle \: \: \sf{x = 2y + 10} \: \: .......(<klux>3</klux>)$

1 নং সমীকরণে x এর পরিবর্তে 2y + 10 বসিয়ে পাই

$\displaystyle \sf{2(2y + 10) - 5y = 0}$

$\implies\displaystyle \sf{4y + 20 - 5y = 0}$

$\implies\displaystyle \sf{y = 20 }$

3 নং সমীকরণ থেকে পাই

$\sf{x = (2 \times 20) + 10}$

$\implies \displaystyle \sf{x = 40 +1 0}$

$\implies \displaystyle \sf{x = <klux>50</klux>}$

∴ রফিকের পিতার বর্তমান বয়স

= ( 50 + 5 ) বছর = 55 বছর

এবং রফিকের বর্তমান বয়স

= ( 20 + 5 ) বছর = 25 বছর

গ. চিত্রে ক এর সমীকরণ দুটিকে স্থাপন করে দুটি সমীকরণ পেলাম

Find how many integers bw 200 snd 500 divisible by 8

Answer»

Answer:

The integers between 200 and 500 which are DIVISIBLE by 8 are 208, 216, 224, ....... , 496.

The given SERIES in an A.P SINCE d = 8.

Here, a = 208, d = 8 and an = 496

an = a + (n - 1)d

→ 496 = 208 + (n - 1)8

→ 8n - 8 = 288

→ 8n = 296

→ n = 37

→ There are 37 integers between 200 and 500 that are divisible by 8.

26.	If set a and b are disjoin sets and n (a) =6 ,n(b)=5, then n (aub)=
Answer» Answer: Two sets are SAID to be disjoint if they have no element in common. EQUIVALENTLY, disjoint sets are sets whose intersection is the empty set. For example, {1, 2, 3} and {4, 5, 6} are disjoint sets,( as they have no element in common) while {1, 2, 3} and {3, 4, 5} are not.(as the element 3 is in common). The union of two sets A and B is the set of elements which are in A, in B, or in both A and B. In figures; FIRST consider the case where the sets A and B are disjoint. In that case, The number of elements in the union (A∪B) is simply the sum of the number of elements in A and the number of elements in B: \|A ∪ B\| = \|A\| + \|B\|. [ \|A\|→no of elements in A and other notations mean similar]. But if A and B overlap, then the latter FORMULA does not hold because, we are COUNTING the elements in the intersection (A ∩ B) twice. Compensating for that leads to the given formula: \|A ∪ B\| = \|A\| + \|B\| − \|A ∩ B\|. [ Note : n(A U B) is also denoted as \|A U B\| ] In above figure of Disjoint sets; Elements in (AUB)=elements in (A)+ elements in (B). In above example, union of disjoint sets is; Element set in A + Element set in B ={1,2,3,5,7,9}.

Answer»

Answer:

Two sets are SAID to be disjoint if they have no element in common. EQUIVALENTLY, disjoint sets are sets whose intersection is the empty set. For example, {1, 2, 3} and {4, 5, 6} are disjoint sets,( as they have no element in common) while {1, 2, 3} and {3, 4, 5} are not.(as the element 3 is in common).

The union of two sets A and B is the set of elements which are in A, in B, or in both A and B. In figures;

FIRST consider the case where the sets A and B are disjoint.

In that case,

The number of elements in the union (A∪B) is simply the sum of the number of elements in A and the number of elements in B: |A ∪ B| = |A| + |B|. [ |A|→no of elements in A and other notations mean similar].

But if A and B overlap, then the latter FORMULA does not hold because, we are COUNTING the elements in the intersection (A ∩ B) twice. Compensating for that leads to the given formula: |A ∪ B| = |A| + |B| − |A ∩ B|.

[ Note : n(A U B) is also denoted as |A U B| ]

In above figure of Disjoint sets;

Elements in (AUB)=elements in (A)+ elements in (B).

In above example, union of disjoint sets is;

Element set in A + Element set in B

={1,2,3,5,7,9}.

40.	Chalk contains 10% calcium 3% and 12% oxygen. find the amount of carbon and calcium (in grams) in 122 kg of chalk.pls tell answer in steps
Answer» Answer: Amount of calcium in the chalk = 12200gm. Amount of carbon in the chalk = 3660gm. GIVEN: A chalk of 122kg contains 10% calcium 3% carbon and 12% oxygen. To FIND: Amount of Carbon and calcium.(in grams) Solution: Given that there is 10% calcium in the chalk. Now, we have to find 10% of 122kg. $= > \frac{10 \times 122}{100}$ $= > 12.2kg$ Now, If we convert 12.2kg into grams then we will have to multiply it by 1000. => 12.2 × 1000 = 12200gm. Now, it is given that the chalk contains 3% carbon. Therefore, we have to find 3% of 122kg. $= > \frac{3 \times 122}{100}$ $= > \frac{366}{100}$ $= > 3.66kg$ Now, If we convert 3.66kg into grams then we will have to multiply it by 1000. => 3.66 × 1000 = 3660gm.

Chalk contains 10% calcium 3% and 12% oxygen. find the amount of carbon and calcium (in grams) in 122 kg of chalk.pls tell answer in steps

Answer»

Answer:

Amount of calcium in the chalk = 12200gm.

Amount of carbon in the chalk = 3660gm.

GIVEN:

A chalk of 122kg contains 10% calcium 3% carbon and 12% oxygen.

To FIND:

Amount of Carbon and calcium.(in grams)

Solution:

Given that there is 10% calcium in the chalk.

Now, we have to find 10% of 122kg.

$= > \frac{10 \times 122}{100}$

$= > 12.2kg$

Now, If we convert 12.2kg into grams then we will have to multiply it by 1000.

=> 12.2 × 1000 = 12200gm.

Now, it is given that the chalk contains 3% carbon.

Therefore, we have to find 3% of 122kg.

$= > \frac{3 \times 122}{100}$

$= > \frac{366}{100}$

$= > 3.66kg$

Now, If we convert 3.66kg into grams then we will have to multiply it by 1000.

=> 3.66 × 1000 = 3660gm.

Answer» ⇒ Given :- A generator consumes ${\sf 2\:{\dfrac{2}{3}$ litres of DIESEL every HOUR. ⇒ To Find :- How MUCH diesel will the generator CONSUME in ${\sf 7\:{\dfrac{1}{5}$ hours? ⇒ Solution :- Diesel consumes every hour = ${\sf 2\:{\dfrac{2}{3}\:L$ = ${\sf{\dfrac{2\:x\:3+2}{3}\:L$ = ${\sf{\dfrac{8}{3}}\:L$ ∴ Diesel consumed in ${\sf 7\:{\dfrac{1}{5}$ hours = ${\sf{\dfrac{7\:x\:5+1}{5}$ = ${\sf{\dfrac{36}{5}}$ = ${\sf{\dfrac{36}{5}}\:x\:{\sf{\dfrac{8}{3}}\:L$ = ${\sf{\dfrac{36\:x\:8}{5\:x\:3}\:L$ = ${\sf{\dfrac{288}{15}\:L$ = 19.2 L Ans. 19.2 L diesel will be consumed in ${\sf 7\:{\dfrac{1}{5}$ hours. $\huge{\boxed{\sf{\ Hence\:\:Proved}}}$

A generator consumes 2\ \frac{2}{3} litres of diesel every hour. How much diesel will the generator consume in 7 \frac{1}{5} hours?

Answer»

⇒ Given :-

A generator consumes ${\sf 2\:{\dfrac{2}{3}$ litres of DIESEL every HOUR.

⇒ To Find :-

How MUCH diesel will the generator CONSUME in ${\sf 7\:{\dfrac{1}{5}$ hours?

⇒ Solution :-

Diesel consumes every hour = ${\sf 2\:{\dfrac{2}{3}\:L$ = ${\sf{\dfrac{2\:x\:3+2}{3}\:L$ = ${\sf{\dfrac{8}{3}}\:L$

∴ Diesel consumed in ${\sf 7\:{\dfrac{1}{5}$ hours = ${\sf{\dfrac{7\:x\:5+1}{5}$ = ${\sf{\dfrac{36}{5}}$

= ${\sf{\dfrac{36}{5}}\:x\:{\sf{\dfrac{8}{3}}\:L$

= ${\sf{\dfrac{36\:x\:8}{5\:x\:3}\:L$

= ${\sf{\dfrac{288}{15}\:L$

= 19.2 L

Ans. 19.2 L diesel will be consumed in ${\sf 7\:{\dfrac{1}{5}$ hours.
