	Three equations in three unknowns		2007-03-18
		Shawna pose la question : You are told that you are working with three different numbers. When the first number is added to twice the other two numbers, the result s 64( i.e x+2y+2z= 64). When the second number is added to twice the other two numbers the result is 62 (y+2x+2z=6). Finally, when the third number is added to twice the other two numbers, the resut is 59 z+2x+2y=59) Determine the three numbers? Penny Nom lui répond.

	Degree		2006-02-09
		Jessica pose la question : I am a 9th grade home school student and have started doing degrees of terms in my math book. The following is some examples they give: 25a to the 4th power is a 4th degree term 67c to the 9th power is a 9th degree term x is really x to the 1st power so it is a 1st degree term 10 is really 10x to the 0 power so it is a 0 degree term They go on to say that every constant is a zero degree term. My question is why isn't a constant, like 10, simply to the 1st power (making is a 1st degree term) like x. Claude Tardif lui répond.

	The quadratic formula		2003-08-31
		Alex pose la question : I am using Houghton Mifflin's Precalculus with Limits book, 2nd edition. However, the first chapter encompasses Algebra review, and I am stuck on a problem. All that's required is to solve the following and verify using a calculator: 3y2+6y+2=0 I have solved the problem using the quadratic formula, but from what I remember, the quadratic formula is used in the case of equations following the AX2+BX+C=0 pattern. As the problem I am attempting uses a y-variable, can I still use the quadratic formula? Since I am not sure what route to take in solving this problem, I am hoping you can assist me. Harley Weston lui répond.
	Water in a cone		2003-08-12
		Adrienne pose la question : Water is poured into a tank in the shape of an inverted right circular cone.ð The height of the tank is 8 m and its radius at the top is 4 m. a. Draw and label a picture to represent this situation.ð (I know how to do this) b. Identify all variable quantities. (h = 8m, r = 4m) c. Find an equation that relates the variable quantities, and reduce the number of variable quantities to two. I was thinking about the equation V = 1/3 pi r2 h, which is the Volume of a cone, but I am stumped as to how I am supposed to "reduce the number of variable quantities to two." Can you point me in the right direction? Penny Nom lui répond.
