A circle has a center of (5,-5) and goes through (6,-2). What is the radius?
azamat
Let O(5, -5) be the center of the circle, and P(6, -2) be a point on this circle.

The distance between points O and P, that is |OP|, is the radius of this circle, 

We use the distance between 2 points formula:

|OP|=\sqrt{ (x_2-x_1)^{2} + (y_2-y_1)^{2} }=  \sqrt{ (6-5)^{2} + (-2-(-5))^{2} }
= \sqrt{ 1^{2}+ (-2+5)^{2}} = \sqrt{1+9}= \sqrt{10} (units)

Answer: \sqrt{10} units

A person exerts a 80 J of work by pulling a block along a horizontal surface with a
Gala2k [10]

According to the solving the displacement  of the block is:

= 40m

<h3>What does force-displacement mean?</h3>

A shift inside of an object's position is referred to as "displacement." It has a magnitude and a direction, making it a vector quantity. An arrow pointing from of the starting point to the finishing point serves as its symbol. For instance, an object's position changes if it moves from position A to position B.

<h3>Why is there a shift in the workforce?</h3>

The scalar product of displacement and force is equivalent to work. The cosine of the angle between two vectors is added to their lengths to form the scalar product of the two vectors. Work is defined as the product of force, displacement, and the sine of the angle formed by the force's and displacement's directions.

<h3>According to the given data:</h3>

The formula for work is W=F × d.

Work done  = 80J

Force = 20N

Displacement = ?

So,

W=F × d.

80 = 20 x d

d = 80/20

d = 40 m

According to the solving the displacement  of the block is:

= 40m

Express the shaded Area as both a faction and a decimal
Ganezh [65]

The shaded area's Fraction= 21/100 and Decimal = 0.21.

<u>Step-by-step explanation:</u>

When an area is divided into multiple smaller regions ( smaller squares ) is called parts.

In case of Squares, it can be divided into either rows or columns, sometimes both.  

Form the given diagram, the square consists of 10 rows and 10 columns which makes 100 (10×10) parts in it.

One fraction is obtained by dividing it by the total number of parts.

In this square, 21 shaded fractions are given.

∴ The fraction of shaded Area = 21/100.

Decimal of shaded Area=0.21.
