Answer:

(2,4)

Step-by-step explanation:

What the formula basically does is calculate the "average" x and y. You probably know how to calculate the average of a set of numbers.

The x coordinates are 1 and 3, their average is 2. You get that by adding them (=4) and dividing by 2. (=2)

The y coordinates are 3 and 5, their average is 4. You get that by adding them (=8) and dividing by 2. (=4)

So, in formula:

M = ( \frac{1+3}2 , \frac{3+5}2) = (2,4)

Find the value of x
avanturin [10]

Answer:

Step-by-step explanation:

1. 56 + 81 = 137

2. The exterior angle theorem means that the 2 angles within a triangle that is on the opposite side of the angle outside the triangle could be added to find the angle that is outside of the triangle.

3. 56 and 81 are on the opposite side of the "x" outside the triangle which means that they could be added together which equals 137 degrees.

Hope this helps!

Suppose a white dwarf star has a diameter of approximately 1.8083 to the power of 4 km. Use the formula 4n to the power of 2 to
aivan3 [116]

ANSWER:

The surface area of the star is 3.2700 x 10^{8} square kilometres.

EXPLANATIONS:

Diameter of the star = 1.8083 x 10^{4} Km.

Surface area of the star = 4n^{2}

Where n is the radius of the star.

So that;

n = \frac{ 1.8083 * 10^{4} }{2}

   = 0.90415 x 10^{4}

n =  0.90415 x 10^{4} Km

Thus,

Surface area = 4 x (0.90415*10^{4} )^{2}

                     = 326994889

Surface area = 3.2700 x 10^{8} km^{2}

Therefore, the surface area of the star is 3.2700 x 10^{8} square kilometres.
