LORD HAVE MERCY!!!

K

Really?

booqee:
k as in kk? or kkk?

as in kkkk!

Nice!

I don't have time for this.. Abeg,how much is the price of petrol in ur area at the moment.#FUEL SCARCITY#.

Who cares?..#sipping my coffee gently#.

It's all abt the individual. Dia r sum apps i can't do without!.

Ok

Lol,exam question num 4.. u skull in oau rit?

sure.

Determine the type of conic section represented by the equation x²/k + y²/(k-9) = 1 in each of the following cases.
(i.) k > 9 ( ii.) 0 < k > 9 and ( iii. ) k < 0. For the case k = 25 ,find the focus or foci and the equation of the directrix or directrixes of the Conic.

Find the Equation of the line joining the centre of the circle x² + y² -2x + 4y - 11 = 0 to the origin.

Let A and B be two fixed points having coordinates ( a , 0 ) and ( -a, 0 ) respectively.Find the locus of a point P which moves in such a way that PA² - PB² = 2k². Where k is a constant.

you may use this:

det[x^2+y^2, x, y, 1; x_1^2+y_1^2, x_1, y_1, 1; x_2^2+y_2^2, x_2, y_2, 1; x_3^2+y_3^2, x_3, y_3, 1]=0.

Then, expand and simplify. (this should be simpler since half of the ordinates are 0's).

NOTE
det means determinant
comma (,) means next column
semicolon (; ) means next line or line break

thanks.

I'm suspecting these were your assignments in Coordinate Geometry/ Elementary Mathematics II. Guess you think we're robots, and I know you'll be acting up superstar for ur class.

Okay na, kontinuuuuuuuu

i started reading the topic nt long and am in need of explanation concerning this question

Help me with this : Find the equation of the circle which touches the axis of y at a distance +4 from the origin and cuts off an intercept 6 from the axis of x.

kindly help me with full solution pls!

Laplacian:
ok. Just google "intersecting arc theorem" because i can't draw the diagram here

please kindly complete the question afta getting the three points!

Laplacian:
heard of Newton's theorem for the radius of curvature of a line?

nah

Laplacian:
at least three points are required to specify a circle, so we must determine the second intercept on the x-axis; if the second intercept is k, then; k=4²/6=8/3
so the three points are; (0,4), (6,0), (8/3,0). Hope it helps!!

it helps buh please kindly give me full solution and explain how k=8/3.THANKS.

agentofchange1:
x=(pX2+qX1)/(p+q)

y=(pY2+qY1)/(p+q)
Where x,y={(4b-2a),(9c-a)}
X1,Y1={(a+b),(3c+5a)}

X2,Y2={(5b-3a),(11c-3a)}
4b-2a={(5b-3a)p+(a+b)q}/(p+q)

P(a-b)=3q(a-b)
P=3q
hence
p:q=3:1

thanks!!!

r= cos@= x/r implies
r²=x implies r²-x=0 implies
x²-x+y²=0 implies
(x- ¹/₂)²+(y-0)²= (¹/₂)²

This is an equation of circle centred at (¹/₂, 0) with radius ¹/₂.

thanks a bunch..

agentofchange1:
3:1

kindly show the workings!

Find in what ratio the points; (4b-2a , 9c-a) divides the line joining the points (a+b , 3c+5a) and (5b-3a , 11c-3a).

Kindly help me with this.
