Tangent is a line that touches the circle at one point going infintiely in both directions

chord is a line that goes from one side of the circle to the other and stays inside the circle, an example would be the diameter which is the longest chord in the circle

secant is a line that goes through the circle at 2 points, it's like a chord but it extends outside the circle

arc length is a section of the circumference
it's like the length of the crust when you cut a slice of pie or the crust of a pizza

The equation for a circle is x^2 - 8x + y^2 -8 =0. what is the equation of the circle in standard form?
yKpoI14uk [10]
You have to complete the square on this to get it into standard form of a circle.  Move the 8 over to the other side because that's part of the radius.  Group together the x terms, take half the linear term which is 8, square it and add it in to both sides.  Half of 8 is 4, 4 squared is 16, so add in 16 to both sides.  I'll show you in a sec.  You don't need to do anything to the y squared term.  This just means that the center of the circle does not move up or down, only side to side, right or left.  Here's your completing the square before we simplify it down to its perfect square binomial. ( x^{2} -8x+16)+ y^{2} =8+16.  Now break down the parenthesis into the perfect square binomial and do the addition of the right: (x-4) ^{2} + y^{2}=24.  This is the standard form of a circle that has a center of (4, 0) and a radius of \sqrt{24}

What is the value of x in the equation 25x^2 = 16?
Lera25 [3.4K]

25x^2 = 16

divide each side by 25

x^2 = 16/25

take the square root of each side

sqrt (x^2) = +- sqrt(16/25)

x = +- sqrt(16)/sqrt(25)

x = +- 4/5

x = 4/5, - 4/5
