Since spring started, Kareem has been surveying the growth of leaves on his neighborhood trees. He goes out every day and comput

es the average number of leaves on a sample of trees. He created a scatter plot where the y-axis represents the average number of leaves on the trees, and the x-axis represents the number of weeks since spring started. Use the 2 given points to write a linear equation that can be used to approximate the data distribution. ​

VIIIe in the standard (x,y) coordmate pralit nas
Savatey [412]

The coordinates of point B are (-4 , -2) ⇒ answer H

Step-by-step explanation:

In any circle

  • The diameter of the circle passing through its center
  • The center of the circle is the mid-point of all diameters

If (x , y) are the coordinates of the mid-point of a line whose end

points are (x_{1},y_{1}) and (x_{2},y_{2}) , then

x=\frac{x_{1}+x_{2}}{2} and y=\frac{y_{1}+y_{2}}{2}

∵ Point C is the center of a circle

∵ AB is the diameter of the circle

∴ C is the mid point of AB

∵ A = (2 , 6) ⇒ (x_{1},y_{1})

∵ B = (x_{2},y_{2})

∵ C = (-1 , 2) ⇒ (x , y)

- Use the rule of the mid-point above

∵ -1=\frac{2+x_{2}}{2}

- Multiply both sides by 2

∴ -2 = 2 + x_{2}

- Subtract 2 from both sides

∴ x_{2} = -4

∴ The x-coordinate of point B is -4

∵ 2=\frac{6+y_{2}}{2}

- Multiply both sides by 2

∴ 4 = 6 + y_{2}

- Subtract 6 from both sides

∴ y_{2} = -2

∴ The y-coordinate of point B is -2

The coordinates of point B are (-4 , -2)

Find the length of the radius of the circle, which is inscribed into a right trapezoid with lengths of bases a and b.
egoroff_w [7]

Answer:

  r = (ab)/(a+b)

Step-by-step explanation:

Consider the attached sketch. The diagram shows base b at the bottom and base a at the top. The height of the trapezoid must be twice the radius. The point where the slant side of the trapezoid is tangent to the inscribed circle divides that slant side into two parts: lengths (a-r) and (b-r). The sum of these lengths is the length of the slant side, which is the hypotenuse of a right triangle with one leg equal to 2r and the other leg equal to (b-a).

Using the Pythagorean theorem, we can write the relation ...

  ((a-r) +(b-r))^2 = (2r)^2 +(b -a)^2

  a^2 +2ab +b^2 -4r(a+b) +4r^2 = 4r^2 +b^2 -2ab +a^2

  -4r(a+b) = -4ab . . . . . . . . subtract common terms from both sides, also -2ab

  r = ab/(a+b) . . . . . . . . . divide by the coefficient of r

The radius of the inscribed circle in a right trapezoid is r = ab/(a+b).

_____

The graph in the second attachment shows a trapezoid with the radius calculated as above.
