Answer:

A. AG = 2 × GD

F. GE = (1/2) × BG

Step-by-step explanation:

The given point <em>G</em> on triangle ΔABC, which is the point of intersection of the medians of the triangle, is the centroid of the triangle

The centroid divides each median line in the ratio 2:1, therefore, we have;

The length of AG = 2 × GD, CG = 2 × GF, and BG = 2 × GE

∴ GE = (1/2) × BG

Therefore, the correct options are;

A. AG = 2 × GD, and F. GE = (1/2) × BG

What is the product -4• [8,-1,-5,9]

xeze [42]

Answer:

The product of given $-4 \cdot \left[\begin{array}{ccc}8\\-1\\-5\\9\end{array}\right]$ is $\left[\begin{array}{ccc}-32 \\4\\20\\-36\end{array}\right]$

Step-by-step explanation:

Consider the given product of a constant and a matrix.

$-4 \cdot \left[\begin{array}{ccc}8\\-1\\-5\\9\end{array}\right]$

To do product we multiply scalar -4 with each element of the matrix given,

$-4 \cdot \left[\begin{array}{ccc}8\\-1\\-5\\9\end{array}\right]= \left[\begin{array}{ccc}-4 \times 8 \\-4 \times -1\\-4 \times -5\\-4 \times 9\end{array}\right]$

On solving further , we get,

$\left[\begin{array}{ccc}-4 \times 8 \\-4 \times -1\\-4 \times -5\\-4 \times 9\end{array}\right]=\left[\begin{array}{ccc}-32 \\4\\20\\-36\end{array}\right]$

Thus, the product of given $-4 \cdot \left[\begin{array}{ccc}8\\-1\\-5\\9\end{array}\right]$ is $\left[\begin{array}{ccc}-32 \\4\\20\\-36\end{array}\right]$

Write a quadratic function in standard form with axis of symmetry x=-5 and y -intercept 3 .

Bezzdna [24]

Answer:

follow the statement below

Step-by-step explanation:

The question you presented here has multiple (un-limited) solutions unless you have another condition to solve for a single solution.

Equation: y = ax² + bx + c

y intercept (0 , 3): c = 3

axis of symmetry x=-5, therefore a corresponding point (-10,3) on the curve

3 = a*(-10)² + b*(-10) + 3

100a - 10b = 0

b = 10a .... any pair like a=0.5 b=5; a=1 b=10 0r a=2 b=20 ..... all fit the function

y = 0.5x² + 5x +3

y = x² + 10x + 3

y = 2x² + 20x +3
