Given:

Vertices of a triangle are D(0,5), E(2,0) and F(-4,2).

To find:

The intersection point of medians DG and EH.

Solution:

We know that, intersection point of all the medians of a triangle is called centroid.

The formula of centroid is

Centroid=\left(\dfrac{x_1+x_2+x_3}{3},\dfrac{y_1+y_2+y_3}{3}\right)

Vertices of a triangle are D(0,5), E(2,0) and F(-4,2). So, the centroid of the triangle is

Centroid=\left(\dfrac{0+2+(-4)}{3},\dfrac{5+0+2}{3}\right)

Centroid=\left(\dfrac{-2}{3},\dfrac{7}{3}\right)

Centroid=\left(-0.666...,2.333\right)

Round each coordinate to the nearest tenth.

Centroid=\left(-0.7,2.3\right)

Therefore, the correct option is C.

Evaluate the polynomial when a. x = 0 and b. X = - 1.<br><br> x^2 - 8x - 7
jeka57 [31]

Answer:

(a) -7, (b) 2

Step-by-step explanation:

a) When x = 0,

=> x² - 8x - 7

=> (0)² - 8(0) - 7

=> 0 - 0 - 7

=> - 7

b) When x = -1,

=> x² - 8x - 7

=> (-1)² - 8(-1) - 7

=> 1 + 8 - 7

=> 9 - 7

=> 2
