Show that the point P(7,7) is on the perpendicular bisector of the line segment joining A (6,-1) to B (0, 3). Also, verify that P is the same distance from A and B. For what values of k is the line y=l tangent to the circle (x-3)^2 + (y+2)^2 = 36? Thanks! Finished :D. Ok, for ...

can someone give me an example of how can one apply any concept (determining the slope and equation of a line, applying linear functions to mathematic applications, solving equations using the method of least squares) in order to decide if data are linear. Since this is not my...

Very easy math
my teacher told me that the inverse of addition was subtraction and that the inverse of subtraction was addition... could you prove it to me -x = (-1)x ((-1)x)^-1 I don't see how I'm suppose to get + x by taking the inverse of -x i've always been told in math to just to the ...

what is the first term of an arithmetic sequence if the 7th term is 21 and the 10th term is 126
Saturday, February 13, 2010 at 10:55pm by Nancy
For an arithmetic sequence, the nth term is given by: T(n)=T(0)+kn, where k is a constant. Knowing T(7)=21, and T(10)=126 we find k using T(10)-T(7) = 126-21 T(0)+10k - (T(0)+7k) = 105 3k = 105 k=35 From the value of k, we find T(0): T(n)=T(0)+35n T(7)=T(0)+35(7) = 21 T(0)=21-...

7th term is 21 ----> a+6d = 21 10th term is 126 ---> a + 9d = 126 subtract them: 3d = 105 d = 35 back in a+6d = 21 -----> a = -189 first term is -189 check: t7 = -189 + 6(35) = 21 t10 = -189 + 9(35) = 126

How do I find the zeros of a polynomial function?
Sunday, March 20, 2011 at 4:54pm by leena
LOL lots of ways. If it is quadratic, use the quadratic equation. Try to factor it. If (ax+b)is a factor then it is zero when x = -b/a Graph it and look for crossings of the x axis. etc

Math: PreCal: Triangles
An isosceles triangle is inscribed in a circle. The shortest side is the base which is 16 cm long. If the radius of the circle is 10 cm, what is the length of side "a"?

Math: PreCal: Triangles
I will assume "a" is one of the equal sides of the triangle make a sketch, by drawing in the altitude to the base of the triangle. draw in the radius to the base vertex. You will have a right-angled triangle with sides 8 and x and hypotenuse 10 x^2 + 8^2 = 10^2 x = 6 ( you ...
