A difficult maths question.?
358399
There is an equation for this, but I don't remember what it is.  Guess and check with a calculator is funner anyways...\nI didn't show much work (how much work is there with guess and check), but I think these are correct. (&=infinity)\n\n1. The range of k is [-2,&)\n\n2. When k=3 then the ratio of a:b will be 1:5.  The equation of the parabola will be y=-X^2 + 4X + 5.\n\n3. I wasn't sure exactly what you were asking on Q 3.  If you are looking for where the tangent line of the parabola at x=0 crosses the x-axis, the point will be (-1.25,0).  If you are saying that from (A,0) to (B,0) in Q 2 is the diameter of a circle, and you are looking for where the tangent line of that circle at x=0 intersects the x-axis then the point is (-4.5,0).\n\nI hope that helps.

damnt i should have paid attention calculus...\n\nlet pam...pam...breat....dimension......carry the one.....as x approaches zero......carry  the two....hold on...\n\nthis could take a while.

This is more of a word problem or a riddle than a math problem.\n\nThe answer is 7 (SEVEN).  Remove its first letter and it becomes EVEN!

Would you please type your entire math question the way it is presented in your book? Your description is not enough for anyone to answer you correctly. Thanks!

I figured it out... the answer is 1/(13*(2-3x))\nIf you need an explanation tell me

I'm writing up a proof right now that this is not possible.\n\nCheck out the pdf at:\nhttp://www.geocities.com/euleratuo/

Directions how to do this can be found in the text book.\n\nDo your own homework!

not possible to factor easily ... try the quadratic formula.

The equations are wrongor insufficient. Post the correct data if you want me to help/ Alternately, you could also message me.

Use analytical trig (hint: sin function).  That should give you the answer you are looking for.
