the radical sign

(B - A)2 - 81 or (B - A + 9)(B - A - 9) If the starting point, A, is taken as zero the the expression simplifies to (B + 9)(B - 9)

An ordered pair shows how much distance you go in the x-direction and the y-direction. It is represented like this (x,y) You can assigned any number you want. (-2,5) (1,-3) (4,5) (-9,11) So to answer your question you can choose any number in the examples I gave you... therefore 1 can be your answer.

For example, if the slope at a certain point is 1.5, you can draw a line that goes through the specified point, with that slope. The line would represent the slope at that point. If you want to graph the slope at ALL POINTS, take the derivative of the function, and graph the derivative. The derivative shows the slope of a function at all points.

An irrational number can't be expressed in the form of a/b, where a and b are integers. But, 41 can be expressed as 41/1 which clearly shows that 41 is not an irrational number.

There is no correct estimate because sqrt(28) is an irrational number and it is always possible to improve on an estimated value.5^2 = 256^2 = 36 so the estimate is between 5 and 6.5.25^2 = (5 1/4)^2 = (21/4)^2 = 441/16 = 27.5 so 5.25 is a better estimate.

A rational number is one that you can express as a ratio (fraction) between two integers, e.g., 3/5, 5/8, 11/3, 9/1. The last example shows that rational numbers include the integers.An irrational number is one that you can not express as such a fraction. This includes most square roots, for example, the square root of an integer is either an integer, or an irrational number. It also includes the numbers pi and e, which are very important in math.A rational number is one that you can express as a ratio (fraction) between two integers, e.g., 3/5, 5/8, 11/3, 9/1.

A rational, non-zero number multiplied by an irrational number always results in an irrational number. Knowing this, you can fairly easily choose a rational number to multiply by any given irrational that will be within your stated range. In this example, I'm going to choose pi (~3.1415926535897932) as the irrational number and x will be the rational number. So we want to satisfying the following inequality: 0.6 < pi * x < 0.66 Dividing everything by pi (which is positive) gives us: 0.6/pi < x < 0.66/pi A quick check on the calculator tells us that: 0.6/pi ~= 0.191 0.66/pi ~= 0.21 So, choosing x = 0.20, we end up with 0.2 * pi as our answer. A quick verification with the calculator shows that 0.2 * pi ~= 0.628, so it's between 0.6 and 0.66. Since 0.2 is 1/5, the equivalent pi/5 is a slightly more aesthetic answer.
