Answer:

Circle is a plane region bounded by by a line that lies at a uniform distance from a fixed point.

Step-by-step explanation:

Circle is a plane figure which is formed by the locus of a point which is at a fixed distance from a fixed point called center and the periphery of the figure is called circumference. The distance between any point on the periphery and the center is called radius of the circle.

Diameter is twice the length of the radius and it is the largest line segment that can be drawn between any two points on the circumference.

Any line segment connecting any two points on the periphery of the circle is called a chord, diameter is the largest chord.

Any line passing through any two points on the circumference of a circle is called a secant.

Any line passing through any one point on the circumference of a circle is called a tangent.

For the following right triangle, find the side length of x. round your answer to the nearest hundredth.
tatyana61 [14]

Answer:

14.87 units

Step-by-step explanation:

The sides of all right triangles share the same relationship known as the Pythagorean Theorem a² + b² = c². Substitute the lengths of the triangle into the theorem and solve for the unknown side. Since the problem does have an attached a picture, assume that a = 10, b = 11, and c = x.

10² + 11² = x²

100 + 121 = 221²

221 = x²

√221 = √x²

14.87 = x

If one root of the equation is 4x^2- 2x+p-4 be the reciprocal of other. then find the value of p​
SashulF [63]

Answer:

p = 8

Step-by-step explanation:

Let one root of the eqn. be alpha . Other root is 1/alpha .

We know that product of both roots of an quadratic eqn. is c/a where "c" is the co-efficient of the constant  & "a" is the co-efficient of x^2.

Here "c" is p-4 & "a" is 4. And the product of roots is 1 ( ∵ prdouct of a number and its reciprocal is 1 )

\frac{c}{a} = 1\\=> \frac{p - 4}{4} = 1\\=> p - 4 = 4\\=> p = 4 + 4 = 8
