8.	Find the ratio in which the point (–3, p) divides the line segment joining the points (–5, –4) and B (–2 , 3 ). Hence find the value of p.
Answer» Step-by-step explanation: let the point A(-5, -4) and B(-2, 3) which DIVIDES the linesegment AB at the point O( -3, p) in the ratio m:N . formula : [mx2+nx1 /m+n , my2+ny1 /m+n] [m(-2) + n(-5) /m+n , m(3) + n(-4) /m+n] [-2m-5n /m+n , 3m-4n /m+n] So, X = -2m-5n /m+n and Y = 3m-4n /m+n -3 = -2m-5n /m+n and p = 3m-4n /m+n -3m-3n = -2m-5n and p(m+n) = 3m-4n -3m+2m = -5n+3n and p(m+n) =3m-4n -m = -2n m = 2n So, put the value m = 2n in p(m+n) = 3m-4n p( 2n +m/2) = 3(2n) - 4(m/2) p/2( 4n+m) = 6n -2m p/2 = 6n-2m /4n+m p = 2 (6n-2m /4n+m) Hence, p = 12n-4m / 4n+m

8.

Find the ratio in which the point (–3, p) divides the line segment joining the points (–5, –4) and B (–2 , 3 ). Hence find the value of p.

Answer»

Step-by-step explanation:

let the point A(-5, -4) and B(-2, 3) which DIVIDES the linesegment AB at the point O( -3, p) in the ratio m:N .

formula : [mx2+nx1 /m+n , my2+ny1 /m+n]

[m(-2) + n(-5) /m+n , m(3) + n(-4) /m+n]

[-2m-5n /m+n , 3m-4n /m+n]

So, X = -2m-5n /m+n and Y = 3m-4n /m+n

-3 = -2m-5n /m+n and p = 3m-4n /m+n

-3m-3n = -2m-5n and p(m+n) = 3m-4n

-3m+2m = -5n+3n and p(m+n) =3m-4n

-m = -2n

m = 2n

So, put the value m = 2n in p(m+n) = 3m-4n

p( 2n +m/2) = 3(2n) - 4(m/2)

p/2( 4n+m) = 6n -2m

p/2 = 6n-2m /4n+m

p = 2 (6n-2m /4n+m)

Hence, p = 12n-4m / 4n+m

then,

2SIN(α)cos(α) = 1

Now, sin(α) + cos(α) = X (let)

Squaring both sides,

{sin(α) + cos(α)}² = X²

If each diagonal of a quadri lateral dividesit into two triangles of equal areas, thenprove that quadrilateral is a paralldogram,

Answer»

Answer:

A QUADRILATERAL ABCD and its diagonals AC and BD divides it into two TRIANGLES of equal areas i.e. AR(△ABC)=ar(△CDB)

and ar(△ABC)=ar(△ACD)

Proof :

⇒ ar(△ABC)=ar(△ACD) ------ ( 1 )

⇒ ar(△ABC)+ar(△ACD)=ar(□ABCD) ----- ( 2 )

From ( 1 ) and ( 2 )

⇒ 2ar(△ABC)=ar(□ABCD) ----- ( 3 )

⇒ and ar(△ABD)=ar(△BCD) ----- ( 4 )

⇒ ar(△ABD)+ar(△BCD)=ar(□ABCD) ---- ( 5 )

From ( 4 ) and ( 5 )

⇒ 2ar(△ABD)=ar(□ABCD) ---- ( 6 )

From ( 3 ) and ( 6 ) we get,

⇒ 2ar(△ABC)=2ar(△ABD)

⇒ ar(△ABC)=ar(△ABD)

SINCE, △ABC and △ABD are on the some base AB. Therefore, they must have equal corresponding altitudes.

i.e. Altitude from C of △ABC= Altitude from D of △ABD

⇒ DC∥AB

Similarly AD∥BC

Hence ABCD is a parallelogram.

Answer» ${\Large{\underline{\underline{\sf{\orange{ \: Answer:-}}}}}}$ In 7.2 days(approx) we can finish it together if we work for 10 hrs a day. ⠀⠀━━━━━━━━━━━━ Given : I can finish the work in 15 days if I work 8hrs a day. You can finish the same work in 62/3 days if you work 9 hrs a day. To Find : In how MANY days we can finish it working together 10 hrs a day = ? SOLUTION : TOTAL time taken by me to complete the work : $\implies$ 15 × 8 $\implies$ 120 hrs Total time taken by you to complete the work : $\implies$ 62/3 × 9 $\implies$ 186 hrs Together we can complete the work per hour : $:\implies \sf \: \: \: \dfrac{1}{120} + \dfrac{1}{186} \\ \\ \\ \\ :\implies \sf \: \: \: \dfrac{186 + 120}{120 \times 186} \\ \\ \\ \\ :\implies \sf \: \: \: \dfrac{306}{ \: 22320 \: } \\ \\ \\ \\ :\implies \sf \: \: \: \dfrac{1}{72}(approx)$ It will take 72 hrs to complete the total work.

I can finish a work in 15 days at 8 hrs aday. You can finish it in 62/3 days at 9 hrsa day. Find how many days we can finishit working together 10 hrs a day.

Answer»

${\Large{\underline{\underline{\sf{\orange{ \: Answer:-}}}}}}$

In 7.2 days(approx) we can finish it together if we work for 10 hrs a day.

⠀⠀━━━━━━━━━━━━

Given :

I can finish the work in 15 days if I work 8hrs a day.
You can finish the same work in 62/3 days if you work 9 hrs a day.

To Find :

In how MANY days we can finish
it working together 10 hrs a day = ?

SOLUTION :

TOTAL time taken by me to complete the work :

$\implies$ 15 × 8

$\implies$ 120 hrs

Total time taken by you to complete the work :

$\implies$ 62/3 × 9

$\implies$ 186 hrs

Together we can complete the work per hour :

$:\implies \sf \: \: \: \dfrac{1}{120} + \dfrac{1}{186} \\ \\ \\ \\ :\implies \sf \: \: \: \dfrac{186 + 120}{120 \times 186} \\ \\ \\ \\ :\implies \sf \: \: \: \dfrac{306}{ \: 22320 \: } \\ \\ \\ \\ :\implies \sf \: \: \: \dfrac{1}{72}(approx)$

It will take 72 hrs to complete the total work.

Working 10HRS each day, it would take :

$\implies$ 72/10

$\implies$ 7.2 days

Therefore, in 7.2 days(approx) we can finish it together if we work for 10 hrs a day.
