Convert (6,π/3) to rectangular coordinates

Convert the point (6,π/3) from polar to rectangular coordinates Please and thank you so much.-y = R sin t and x = R cos t y = 6 sin(π/3) x = 6 cos(π/3) And done

Algebra proof question

Let a,b,c be given real numbers such that a > b > c >0. Prove that there exists a number N such that: a^n > b^n + c^n for every n>= N-Ok so the right hand side, b^n+c^n, is less than b^n+b^n = 2b^n si

The centroid of the triangle formed by the pair of lines 12x^2-20xy+7y^2=0 and the line 2x-3y+4=0 is

1)[7/3,-7/3] 2)[8/3,8/3] 3)[-4/3,-4/3] 4)none of these-the given pair is 12x^2-20xy+7y^2=0 (6x-7y)(2x-y)=0 y=6/7x,y=2x so,the lines forming the triangle are y=2x y=6/7x and 2x-3y+4=0 0n solving above

Need help with Elimination Method Plz Help? :)

I need help on how to do these 7x-4y=33 6x-7y=14 How would i do this and put the answer in an ordered pair and thank you for your time :)-(7x-4y=33)*7 (6x-7y=14)*4 49x-28y=231 -(24x-28y=56) 25x=175

The lines 3x-4y+4=0 and 6x-8y-7=0 are tangents to the same circle the radius of the circle is

1.11/5 2.3/2 3.3/4 4.11/10-3x-4y+4=0.........(1) 6x-8y-7=0 2(3x-4y-7/2)=0 3x-4y-7/2=0..........(2) (1) and (2) are parallel distance between (1) and (2) =l4+7/2l/sqrt(9+16) =15/2*5 =3/2 radius=3/2/2=

If xsqrt(1+y)+ysqrt(1+x)=0,then dy/dx is

1.x+1/x 2.1/1+x 3.-1/(1+x)^2 4.x/1+x-given xsqrt(1+y)+ysqrt(1+x)=0 xsqrt(1+y)=-ysqrt(1+x) squaring on both sides x^2(1+y)=y^2(1+x) x^2-y^2+x^2y-xy^2=0 (x-y)(x+y)+xy(x-y)=0 x=y or x+y+xy=0 x=y does not
