How many ways can an arc be tangent to 2 lines?

Although normally it is the line that is considered to be tangent to an arc, an arc can be tangent to infinitely many lines and so the answer to the question is: in infinitely many ways.

What happens when two tangent segments meet at a point outside a circle?

Nothing "happens". They meet, and the rays continue merrily along their ways, never to meet again!


Why does the value of the tangent ratio of a given angle not depend on the right triangle?

The tangent ratio is defined in several different ways. One of these consists of infinite series: the series for the tangent function contains some coefficients which are difficult to calculate. However, the tangent series van be easily calculated from the sine and cosine ratios.sin(x) = x - x3/3! + x5/5! - x7/7! + ...andcos(x) = 1 - x2/2! + x4/4! - x6/6! + ...where x is the angle defined in radians, and n! represents 1*2*3*...*n.So tan(x) = sin(x)/cos(x).None of these require a right angle.


How do you prove in 3 different ways that the line of y equals x -4 is tangent to the curve of x squared plus y squared equals 8?

If: y = x-4 and y = x2+y2 = 8 then 2x2-8x+8 = 0 and the 3 ways of proof are: 1 Plot the given values on a graph and the line will touch the curve at one point 2 The discriminant of b2-4ac of 2x2-8x+8 must equal 0 3 Solving the equation gives x = 2 or x = 2 meaning the line is tangent to the curve

Compare and contrast the ways external and internal forces produce surface landforms?

External forces, such as weathering and erosion, shape surface landforms through the gradual breakdown and transportation of rocks and soil. Internal forces, like tectonic activity, produce landforms by causing uplift, folding, faulting, and volcanic eruptions that change the earth's crust. Both external and internal forces work together to create and modify the Earth's surface features over time.


Why is essential to balance internal and external recruitment?

Internal recruits are employees who already know the company and its ways of working. Additionally you know what their performance, limits and abilities are like. Internal recruitment also gives opportunities to staff to get promoted, in other words it is a major incentive for employees to develop their full potential. External recruits mean you can bring in people to your organization with new ideas and knowledge to keep things fresh.
