Answer:

Option (A)

Step-by-step explanation:

If the extreme ends of a segment are (x_1, y_1) and (x_2,y_2),

Coordinates of the mid-point will be = [\frac{(x_1+x_2)}{2},\frac{(y_1+y_2)}{2}]

And the length of the segment is = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Coordinates of the extreme ends of the ST are S(-3, 2) and T(5, 8).

Therefore, coordinates of the midpoint of ST will be = (\frac{-3+5}{2},\frac{2+8}{2})

                                                                                       = (1,5)

Length of ST = \sqrt{(5+3)^2+(8-2)^2}

                      = \sqrt{64+36}

                      = 10 units

Option (A) will be the answer.

Given the function defined in the table below, find the average rate of
AURORKA [14]

Answer:

Average rate of change = \frac{2}{5}

Step-by-step explanation:

Average rate of change of a function 'f' in the interval a ≤ x ≤ b is given by,

Average rate of change = \frac{f(b)-f(a)}{b-a}

We have to find the average rate of change in the interval 20 ≤ x ≤ 65

From the table attached,

f(65) = 32

f(20) = 14

Average rate of change = \frac{32-14}{65-20}

                                        = \frac{18}{45}

                                        = \frac{2}{5}

Therefore, average rate of change in the given interval is \frac{2}{5} .

#2 Find the slope given the points (6,-12) and (15,-3)*
castortr0y [4]

Greetings :)

To find slope of two points we will need to use this equation:   \frac{y^2-y^1}{x^2-x^1}

 x^1     x^2     y^1    y^2  

( 6 , -12 ) ( 15 , -3 )

Now let's replace the equation with the numbers. (it will be a fraction).

\frac{-3-(-12)}{15-12}         =         \frac{9}{9}

The equation equals 9 over 9, which also equals 1.

The slope of the line is 1.

The circumference of a circle is 314 units. What is the area?
german

Answer:

7850 square units

Step-by-step explanation:

According to the question;

  • Circumference of a circle is 314 units;

We are required to find the area of the circle;

  • First, we need to ask ourselves how we get the perimeter of a circle;

Perimeter of a circle = pi × D or 2 pi r

Therefore;

Rearranging the formula;

D = Perimeter ÷ pi

Taking pi to be 3.14

Then;

Diameter = 314 units ÷ 3.14

              = 100 units

But, radius = Diameter ÷ 2

                  = 100 units ÷ 2

                  = 50 units

We also need to know how we calculate the area of a circle;

Area of a circle = pi×r²

Therefore;

Taking pi as 3.14

Then, Area = 3.14 × 50²

                   = 7850 square units

Thus, the area of the circle is 7850 square units
