Answer:

18cm

Step-by-step explanation:

A median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle.

A centroid of a triangle is defined as the point where the three medians of the triangle meet. It is also called the center of gravity of the triangle.

In the Triangle RST, point X is the centroid where the medians RW, TV and SU intersect.

One Special Property of the centroid is that it divides each median in the ratio 2:1.  (with the larger part being the part from the altitude)

Given RW =27

RX=\frac{2}{3}RW\\ =\frac{2}{3}X27=18cm

Find DY divided by DX by implicit differentiation y=sinxy 
amm1812

Answer:

Step-by-step explanation:

y = sin(xy)\\\frac{d}{dx}y=cos(xy)(\frac{d}{dx}(xy))\\  \frac{d}{dx}y = cos(xy)(y + x*\frac{d}{dx}y)\\ write \: \frac{d}{dx}y \: as\:y'\\y' = cos(xy)(y+xy')\\y' = ycos(xy) + xy'cos(xy) \\y'-xy'cos(xy) = ycos(xy)\\y'(1-xcos(xy)) = ycos(xy)\\\\y' = \frac{ycos(xy)}{1-xcos(xy)}

A superhero recently asked his nemesis how many cats she has. she answered with a riddle: "seven eights" of my cats plus two" ho
ryzh [129]
<span>If the nemesis has "7/8 of her cats plus 2" it can be written like this: 7/8 x + 2 = x, where x is the number of the cats. After that we can solve the equation. x - 7/8 x = 2; 1/8 x = 2; x = 2 : 1/8 = 2 * 8 = 16. Answer: The nemesis has 16 cats.</span>

The formula for any geometric sequence is a n = a 1 · r n - 1 , where a n represents the value of the nth term, a 1 represents t
AfilCa [17]

Answer:

Step-by-step explanation:instead, try making the subscripts and superscripts stand out:

                         n-1

a    =  a         * r

 n         n-1

Believe me, it's worth the extra work to do this!!

Given the sequence   -3, -6, -12, -24, you can easily see that the first term,

a         is    -3.  The common factor is 2.  Note how (-3)*2=-6, and so on.

  1

So, a       = -3 and r=2.

        1

So the formula for this geometric sequence is  

                  n-1

a     =  -3*2

  n

Factor completely <br> 4x^2 + 24x - 64
lara31 [8.8K]
First see you can factor out 4. What is left is x^2 + 6x - 16.
That can be factored as (x+8)(x-2) so the total factorization is

4(x+8)(x-2)
