Determine el radio vector del punto medio del segmento que se forma al unir los puntos (-8, 7) y (6, 3).
tiny-mole [99]

Answer:

The radius vector is (-8, 7) and (-1 , 5).

Step-by-step explanation:

Determine the radius vector of the midpoint of the segment that is formed by joining the points (-8, 7) and (6, 3).

The end points are (- 8, 7) and (6, 3) .

The mid point is given by

x = \frac{x' + x''}{2}\\\\y = \frac{y' +y''}{2}\\\\x =\frac{- 8 + 6}{2}=-1\\\\y = \frac{7+3}{2} = 5

So, the radius vector is (-8, 7) and (-1 , 5).

Helllp geometry! Pls!

He should use the Pythagorean Theorem to find the missing length.


Since KT is tangent to the circle and TL reaches the center of circle L, the measure of angle LTK is 90 degrees. This means that triangle LTK is a right triangle which means the Pythagorean Theorem can be used.

So,
TL²+(12)²=(13)²
=> TL²+144=169
=> TL²=25
=> TL = 5

Therefore, the radius of circle L is 5 feet.

Find the volume of a cone with radius 10 feet and height of 4 feet.
Sveta_85 [38]

Answer:

\frac{400}{3} \pi

Step-by-step explanation:

Formula for Cone: πr^{2}\frac{h}{3}

Since we have all the components, we can find the volume of the cone.

R = 10

H = 4

π10^{2}\frac{4}{3}

10×10 = 100

100π}\frac{4}{3}

}\frac{4}{3}×100

4       100          400

---  ×   -----    =    ------

3          1              3

Answer: \frac{400}{3} \pi

Hope this helped.
