Answer:

(-3,4)

(-1,4)

(-3,7)

Step-by-step explanation:

(1,1) → (1-4, 1+3) → (-3,4)

(3,1) → (3-4, 1+3) → (-1,4)

(1,4) → (1-4, 4+3) → (-3,7)

In equilateral ΔABC, AD, BE, and CF are medians. If FO = 4, then AE = A) 4 B) 4 3 C) 8 D) 12

vampirchik [111]

Firstly, we need to draw triangle

we know that

O is a centroid

and centroid divides median into 2:1

so,

$\frac{CO}{FO} =\frac{2}{1}$

we have FO=4

so, we can plug it

$\frac{CO}{4} =\frac{2}{1}$

$CO=8$

now, we can find CF

CF=OC+FO

CF=8+4

CF=12

now, we can see triangle ACF is a right angled triangle

so, we can use pythagoras theorem

$x^2=(\frac{x}{2} )^2+12^2$

now, we can solve for x

$\frac{3x^2}{4}=144$

$x^2=192$

$x=8\sqrt{3}$

Since, it is equilateral triangle

so,

$AC=x=8\sqrt{3}$

we know that

E is a mid-point

so,

$AE=\frac{AC}{2}$

now, we can plug values

$AE=\frac{8\sqrt{3}}{2}$

$AE=4\sqrt{3}$ ................Answer

Answer: $V=234\ yd^3$

Step-by-step explanation:

By definition, the volume of a rectangular prism can be calculated with the following formula:

$V=lwh$

Where "l" is the length, "w" is the width and "h" is the height of the rectangular prism.

In this case, you can identify that the length, the width and the height of this rectangular prism given in the exercise, are:

$l=13\ yd\\\\w=6\ yd\\\\h=3\ yd$

Then, knowing its dimensions, you can substitute them into the formula:

$V=(13\ yd)(6\ yd)(3\ yd)$

Finally, evaluating, you get that the volume of that rectangular prism is:

$V=234\ yd^3$
