Let line divides 2x+3y-1=0 to the segment joining (5,6) and (-4,-3) in k:1let point of intersect be (a,b)by intersection formula(a,b)=(-4k+5/k+1 , -3k+6/k+1)a=-5k+5/k+1 and b=-3k+6/k+1these point will also lie on line 2x+3y-1=0.hence point will satisfy this equation2×(-4k+5/k+1) + 3×(-3k+6/k+1) -1 =0-8k+20-9k+18-k-1=0-18k+37=0k=37/18ratio will be 37:18

A = (-1, 7) and B = (4, -3)

So,x1=−1,y1=7,x2=4andy2=−3

We also have;m1=2andm2=3

Let us assume P is the point of division

Coordinates of P can be calculated as follows by using section formula:

x=m1x2+m2x1/m1+m2

=2×4+3×−1/5

=8−3/5=5/5=1

y=m1y2+m2y1/m1+m2

=2×−3+3×7/5

=−6+21/5=15/5=3

Hence, P = (1, 3)

Piaget was a Swiss psychologist

Born on the island of Samos, off Greece, in the Mediterranean Sea,Pythagoraswas the son of Mnesarchus. Little is known about his earlylife. After studying in Greece, he fled to southern Italy to escape the harsh rule of Polycrates (died c. 522 B.C.E. ), who came to power about 538 B.C.E.

2x-y+3z=9,x+y+z=6,x-y+z=2 solve in matrix method. 2x-y+3z=9,x+y+z=6,x-y+z=2 solve i

2x - y + 3z = 9x + y + z = 6x - y + z = 2

Thus matrix can be formed as[ 2 -1 3 1 1 1 1 -1 1 ] [ x y z ] = [ 9 6 2 ]orA X = BA inverse Can be calculated asAdj A = [ 2 0 -6 -2 -1 1 2 -1 -1 ]l A l = 2 (1 +1) - 1 (1 - 1) + 3 (-1 - 1) = 4 - 0 -6 = -2ThusA inverse = [ -1 0 3 1 1/2 -1/2 -1 1/2 1/2 ]Thus

plz like my answer

Since circle is divided into 4 equal parts and complete circle is 360 degree. AOD=AOC=BOC=BOD= 360/4 = 90 degree. BOD is a straight line = 180 degree. 180 = 2*90AOB = 2 times AOC

Angle AOB is twice the angle AOC.

angle AOC = 45

angle AOB = 90

therefore angle AOB = 2×AOC = 2×45 = 90angle AOB is twice the angle AOB

Thank you bhai

Given a conical tent with

Height ( h ) = 8m

Radius ( r ) = 6m

So, its length = l2= h2+ r2

= l2= ( 8 )2m + ( 6 )m2

= l2= 64m + 36m

= l2= 100m

= l = 10m

Curved surface area of the cone = TTrl

= 3.14 x 6m x 10m

= 188.4 cm2

The extra length of material that will be required for stiching margins and wastages in cutting is approx 20 cm = 0.2m

So, its length = l - 0.2m

and its width = 3m

area of sheet = CSA of tent

so the area of the trapaulln = l x b

= ( l - 0.2m ) x 3m = 188.4m2

= l - 0.2m = 62.8m2

= l = 63m

Therefore, length of the trapaulin sheet required is 63m.

सबसे पहले इसका उलटा मान लेते हैं; यानि मान लेते हैं कि√5एक परिमेय संख्या है।ऐसी संख्या के लिये a और b दो ऐसी संख्या होंगी जहाँ b ≠ 0 तथा a और b कोप्राइम होंगे, ताकि;√5=a/bया,b√5=a

दोनों तरफ का वर्ग करने पर यह समीकरण मिलता है;5b^2=a^2इसका मतलब है कि a^25 से डिविजिबल होगा और इसलिये a भी 5 से डिविजिबल होगा।लेकिन यह हमारी पहले के मान का विरोधी है कि a और b कोप्राइम हैं, क्योंकि हमें 5 के रूप में a और b का कम से कम एक कॉमन फैक्टर मिल गया है।यह हमारे पहले मानी हुई संभावना किb√5प्रमेय संख्या है का भी विरोधाभाषी है।इसलिए एकb√5अप्रमेय संख्या है सिद्ध हुआ।
