<span>The ratio of the rise and the run, called the difference quotient, that equals the value of the tangent of the angle between the direction of the secant line and x-axis, becomes the slope (gradient) of the tangent line as the difference Dx tends to zero, and is called the instantaneous rate of change or the derivative at the point of the function.
For a given function ƒ and point (x1, ƒ (x1)), the derivative of ƒ at x = x1 is the slope of the tangent line through the point (x1, ƒ (x1)), i.e., f '(x1) = tan at
The gradient of a curve at a point on its graph, expressed as the slope of the tangent line at that point, represents the rate of change of the value of the function and is called derivative of the function at the point

Answer:
x = 9, WX = 34
Step-by-step explanation:
Two tangent segments to a circle from the same external point are congruent, that is
WX = YX, substitute values
7x - 29 = 2x + 16 ( subtract 2x from both sides )
5x - 29 = 16 ( add 29 to both sides )
5x = 45 ( divide both sides by 5 )
x = 9
Thus
WX = 7x - 29 = 7(9) - 29 = 63 - 29 = 34
Base ten means the regular number system that we usually use. So it would be: 3,526,019
40 percent of 35 as a fraction would be reduced down to 1 1/7 or in simplest form, decimal, 1.142857.
