What must be added to each term of the ratio 49 : 68 so that it become 3 : 4

Answer»

Hiii FRIEND,

LET X must be added to 49:68 to become it 3:4

THEREFORE,

49/68 + X = 3/4

49 + 68X ÷ 68 = 3/4

4(49+68X) = 68 × 3

196 + 272X = 204

272X = 204-196

272X = 8

X = 8/272 = 2/68 = 1/34

Hence,

1/34 must be added to 49/68 to MAKE it 3/4

HOPE IT WILL HELP YOU.... :-)

Factorise 4x(2x+3)(2x-1)(x+1)-54. The answer is 2(2x²+2x+3)(4x²+4x-9), but I don't know how. Plz help fast. Thanks!!

Answer»

4x(2x+3)(2x-1)(x+1)-54. 

(8x² + 12)(2x-1)(x+1)-54

(64x³+24x-8x²+12) (x+1) -54

64x^4+24x²-8x³+12x+64x³+24x-8x²+12

{bring all LIKE terms together}

64x^4+24x²-8x²-8x³+64x³+12x+24x+12-54

=64^4 + 16x² + 56x³ + 36X - 42  is the answer.............

Why taylor series bezier curve is advantageous

Answer»

A Bézier curve is a parametric curve frequently used in computer graphics, animation, modeling, CAD, CAGD,  and many other related fields.

Bezier curves and surfaces are curves written in Bernstein basis form; so, they are known many years ago. However, these applications are used heavily only in the last 30 years. Why? What are your thoughts and opinions?

http://en.wikipedia.org/wiki/B%C3%A9zier_curve

Bézier curves are also used in the time domain, particularly in animation and interface design, e.g., a Bézier curve can be used to SPECIFY the velocity over time of an object such as an icon moving from A to B, rather than simply moving at a fixed number of pixels per step. When animators or interface designers talk about the "physics" or "feel" of an operation, they may be referring to the particular Bézier curve used to control the velocity over time of the move in question.

The mathematical basis for Bézier curves — the Bernstein polynomial — has been known since 1912, but its applicability to graphics was understood half a century later. Bézier curves were widely publicized in 1962 by the French engineer Pierre Bézier, who used them to design automobile bodies at Renault. The STUDY of these curves was however first developed in 1959 by mathematician Paul DE Casteljau USING de Casteljau's ALGORITHM, a numerically stable method to evaluate Bézier curves, at Citroën, another French automaker.

In a 100m race a beats b by 10m and c by 13m. in a race of 180 m b will beat c by

Answer»

Let speed of a is v and he COMPLETED DISTANCE in t. i.e. v*t=100
therefore,
speed of b is 90/t and speed of c is 87/t.

for 180M, TIME taken by b is 180/(90/t)=2t.
and in this time interval of 2t distance covered by c is 2t*(87/t)=174m
hence b will beat c by 6m.

Solve example1)An obtuse angle of a rhombus is greater than twice at acute angles by 30 find the measure of each angel Step by step Thanks

Answer»

Opposite angles of rhombus are equal.
so LET acute ANGLE be x then obtuse angle would be 2x +30 then by angle sum property of quadrilateral
x+2x+30 +x+2x+30 = 360°
6x +60=360
6x = 360-60 = 300
x = 300/6
x= 50
now obtuse angle= 2x +30 = 2*50 +30
=> 100+30=130
Acute angle =60
Obtuse angle= 130
Since opposite angles are equal therefore all 4 angles are
60,130,60,130
hope it HELPS.
If it helps mark it brainliest. Thanks

How to form a differential equation for vector space

Answer»

The first vector SPACE you learn about is probably the "arrows" in the xy-plane that go from the origin to any point (x,y).  You can add "arrows" together -- e.g. the vector to (a,b) plus the vector to (c,d) is the ARROW from the origin to (a+c,b+d).  You can scale "arrows" -- e.g. if you want to scale the vector from the origin to (a,b) by the CONSTANT c, you get the vector from the origin to the point (ca,cb).   These scalable, addable "arrows" satisfy all the requirements for a vector space.  

But they aren't the only things that do.  Arrows in 3 dimensions from the origin to the points of the form (x,y,z) with the usual ideas of adding and multiplying work too.  But so do things that aren't at all like arrows in Euclidean space.  As it turns out, the set of all solutions of a LINEAR homogeneous ODE with constant coefficients is one such set that isn't at all like vectors in Euclidean space, but they are a vector space.  How does this work?

A solution to the equation is now a vector.  Given any two vectors (i.e. solutions) in the space, you can add them together and get a vector in the space.  Why?  Because the sum of any two solutions MUST be a solution.  (That's a REALLY important property of linear homogeneous odes and isn't too hard to show.  You should show it yourself if you haven't seen it already.)  Also, given a vector (i.e. a solution) in the space, you can multiply it by a constant and get another vector in the space.  Again, that's a really important property of such equations that isn't hard to show.

Find the greatest number of five digit exactly divisible by 9, 12, 15, 18, 24

Answer» To FIND:
 ⇒ The greatest number of five-digit EXACTLY divisible by 9, 12, 15, 18, 24.

Solution:
⇒ LCM of 9, 12, 15, 18 and 24 by division method is 360. The largest number of five digits = 99999.
⇒ The quotient when 99999 is DIVIDED by 360 is 277 and the remainder is 279.
⇒Greatest number of five digits divisible by 9, 12, 15, 18 and 24 = 99999 - 279 =99720.

⇒ ∴ The greatest number of five-digit exactly divisible by 9, 12, 15, 18, 24 = 99720
