a ball is kicked at a velocity of 40m/ss at 60 degrees above the horizontal A) When is the ball 25m above the ground? b) when and where will the ball strike the ground again c)if the ball is to pass over a 25m high, between what two distnace from the launching point can the barrier be placed

find the equation of the locus of point p(x,y) that moves so that it is equidistant from the x-axis and the y-axis also find the equation of the locus of a point P that moves so that PA is twice the distance of PB where A = (0,3) and B = (3,-1)

sry, already got the answer

Find the equation of the locus of point p(x,y) that , moves so that it is always 9 units from the point (-1,-1) plz show working out

also can u show the working out

i got the working out bit, u reakon u cacn telll us answer becuase teh book doesnt show the answer

theres two questions that i dont understand One root of 3x^2-2(3b+1)x+4b = 0 is 8 Find the value of b also In the quadratics equation (k-2)x^2 - 5x+ 2k + 3 = 0, the other roots are reciprocals of each other find the value of k

need help with maths question(i add another question) Find the value of m in x^2+2mx-6 = 0 if one of the root is zero can ya plz show the working out Also another question ] Find the qudratic equation whose roots are 3 - √2 and 3 + √2 also For what value of k will the...

thanx, i understand it better

can ya also show working out

first question the parabola y = 3x^2 - kx +2 is symmetrical about the line x= 1/2. find the value of k and the minimum value of the expression second question find the two numbers whose sum is 12 and which have a maximum product. let two numbers be x and 12-x if you have spare time...

thanx people, i understand how to use it

how does this equation work a^2+b^2=(a+b)^2-2ab is there some technique getting there or is it just is

sry for the disturbance, but i have some trouble with some question. can someone help me with some questions if it doesnt trouble a find the values of k for which 5+4x-x^2=k has equal roots and also if (2k+3)^2 - 4kx+4 = 0 has equal roots find k also can ya plz show the working out

thanks, for the help, made it sound so easy

plz, also can you show working out

i need help with 3 question that i dont understand? first question if x² = ax(ax-1)+bx for more than two values of xd, find a and b second question Find a, b and c if: x² = a(x+1)²+bx+c the equal(=) sign suppose to mean similar third question Find the values for A and B if...
