Answer:

See explanation

Step-by-step explanation:

The question is incomplete, as the graph or points of each city are not given.

So, I will provide a general explanation.

To calculate the equation of line through two points;

Start by writing out the coordinates of the two points.

For instance:

London = (4,6)

Warsaw = (20,10)

This points will be represented as:

(x_1,y_1) = (4,6)

(x_2,y_2) = (20,10)

Calculate the slope (m)

m = \frac{y_2 - y_1}{x_2 -x_1}

m = \frac{10 - 6}{20 - 4}

m = \frac{4}{16}

Simplify

m = \frac{1}{4}

The equation is then calculated as:

y = m(x - x_1) + y_1

This gives:

y = \frac{1}{4}(x - 4) + 6

Open bracket

y = \frac{1}{4}x - 1 + 6

y = \frac{1}{4}x +5

<em>Apply the above steps in the original question</em>

Answer: 7.312

Step-by-step explanation: Hope this helped but you have to first divide 4/2 which makes 2, then 2/2 which is 1, 6/2 which makes 3, then 14/2 which makes 7

4/2= 2

2/2=1

6/2=3

Find the equation of the circle whose center and radius are given.<br> center (5,6), radius = 3
MArishka [77]

Answer:

(x - 5)² + (y - 6)² = 9

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (5, 6) and r = 3, thus

(x - 5)² + (y - 6)² = 9 ← equation of circle
