In triangle ABC, medians AD, BF, and CE intersect at G. What is the length of GE is CH=12?
sashaice [31]
You do not have any point labeled "H" in your diagram.

What I can tell you is that point "G" (where all 3 medians meet) is called a centroid.
<span>
Along </span>each<span> median:</span>
the distance from EACH vertex to the centroid (point G) is TWICE the distance from the centroid to the side.
<span>CG = 2*GE   AG = 2*GD   BG = 2*GF

I need help fast pleasee
trapecia [35]

Answer:

<em>y = - cos ( </em>\frac{3}{4}<em> x + </em>\frac{\pi }{4}<em> ) </em>

Step-by-step explanation:

y = A cos ( Bx + C) + D

Vertical shift D = 0

A = - 1

Compression / Stretching B

Period of given function is \frac{8\pi }{3}

Period of cos x is 2π

\frac{8\pi }{3} = \frac{2\pi }{B} ⇒ B = \frac{3}{4}

Horizontal shift is C ÷ B

Horizontal shift of given function is \frac{\pi }{3}

\frac{\pi }{3} = C ÷ \frac{3}{4} ⇒ C = \frac{\pi }{4}

So, the equation of given function is

<em>y = - cos ( </em>\frac{3}{4}<em> x + </em>\frac{\pi }{4}<em> ) </em>

Find the numerical values of -3|x|+2x-1 if x=-5. PLSSSS HELP
Kisachek [45]

Answer:

26

Step-by-step explanation:

Since x = -5, we can replace x with it's numerical -5, right? The problem tells you that x is equal to -5. So, just replace any x you see with -5.

So in this case,

-3|x|+2x-1

turns into:

-3|(-5)|+2(-5)-1

You can use a calculator or solve it by hand to see what the answer is.

-3|(-5)|+2(-5)-1\\-3(5)+2(-5)-1\\-15+(-10)-1\\-25-1\\-26
