Answer:20π

Step-by-step explanation:

equation of the circle

(x+3)² + (y-5)² = r²

now, (-9, -3) lies on it

So, (-9+3)² + (-3-5)² =r²

36+ 64 = r² =100

hence, r =10

So, circumference = 2πr = 20π

when price of indomie noodles was lowered from #50 to #40 per unit, quantity demanded increases from 400 to 600 units per week.

Nataly [62]

Answer:

The price elasticity of demand is -10

Step-by-step explanation:

Given

$p_1,p_2 = 50,40$

$q_1,q_2 = 400,500$

Solving (a): The coefficient of price elasticity of demand (k)

This is calculated as:

$k = \frac{\triangle q}{\triangle p}$

So, we have:

$k = \frac{500 - 400}{40 - 50}$

$k = \frac{100}{-10}$

$k = -10$

Because |k| > 0, then we can conclude that the company made a wise decision.

Ranking in order from best to worst : Point, line, plane.

Step-by-step explanation:

12.A point in geometry is a location with no size and is shown by a dot. A point is the most fundamental object in geometry that represents a position.

A line can be defined as a connected set made up of infinitely many points.A line has one dimension and extends in infinitely in different directions.It has zero width and zero height.

A plane is an infinite set of points forming a connected flat surface that extends infinitely far in all directions. In a plane, the width, length and height are infinite.

13.

Points S and V are collinear points.

Points R, and U are collinear points

Points Q and T are collinear points

The figure has no plane indicated

To multiply a decimal number by 1000 move the decimal point

KengaRu [80]

You'll have to move the decimal point to the right as many places as there are zeros in the factor,then you'll have to move the decimal point one step to the right (10 has one zero),and move the decimal point two steps to the right (100 has two zeros).
