Answer:

13.5=k

Step-by-step explanation:

When 2 triangles are similar the ratio of their corresponding sides are equal.

\frac{XY}{YZ}=\frac{AB}{BC}\\\\

Plug in the values given:

\frac{4.5}{3} =\frac{k}{9}

Cross Multiply

40.5=3k

Divide to isolate k

13.5=k

There are 19 figure skaters in the Olympic women's competition, including 3 Americans. The gold medal goes to first place, silve
muminat

There are three different choices for the American.

There are 16 different choices for the first non-American and 15 different choices for the other non-American.

So, there are 3 x 16 x 15 different groups.

But, order is important -- who gets the gold, who gets the silver, and who gets the bronze -- there are 6 different ways to arrange the 3 winners (3! = 6).

Thus, there are 6 x 3 x 16 x 15 different results.

8. The sum of the interior angles of a triangle is 180 degrees. For a quadrilateral the sum is 360 degrees. For a pentagon the s
-Dominant- [34]
Since the formula for interior angles is 180 x (n-2), n being the amount of sides of the polygon, you replace n with 35, and you get this:

180 x (35-2), or 180 x 33, which equals 5940

What is the axis of symmetry for f(x) = −3x2 + 12x − 6?
Marta_Voda [28]
The axis of symmetry can be found by finding the average of the zeros, a derivation from the conservation of energy :P, or by finding the point when the velocity is equal to zero.

df/dx=-6x+12 so df/dx, velocity, equals zero when:

-6x+12=0

6x=12

x=2  so the axis of symmetry is the vertical line x=2

....

average of zeros...

3x^2-12x+6=0

x^2-4x+2=0

x^2-4x=-2

x^2-4x+4=2

(x-2)^2=2

x-2=±√2

x=2±√2  so the average of the zeros is obviously 2.

....

conservation of energy

vf-vi=at  When vf=0, this is the maximum value for f(x)...

-vi=at, vi=b and a(acceleration)=2a(from quadratic) and t=x

-b=2ax

x=-b/(2a)  in this case

x=-12/(2(-3))

x=-12/-6

x=2
