Answer:
Step-by-step explanation:
Using the graph we can notice something
let's take the abscissa -2 and -4
- the ordinate that goes with -2 using g is 0
- the ordinate that goes with -4 using f is 0
so we can say that :
f(-4)=g(-2)
wait we khow that g(x)=f(k*x)
so x= -2 then let's replace it in the expression : f(k*x)
we get f(-4)=g(-2)=f[k*(-2)]
let's solve the equation: -2k = -4
k = -4/-2
k=2
so finally we get k=2
let's check :
from the graph we get :
we have (-1)*2 = -2
so it is true
The answer is C Radius because look o. the outside it's clearly bigger
Answer:
12 brown
Step-by-step explanation:
You would take 3 x 4 which equals 12. And then you would take 12 x8 which would equal 96
Step-by-step explanation:
If the parabola has the form
(vertex form)
then its vertex is located at the point (h, k). Therefore, the vertex of the parabola
is located at the point (8, 6).
To find the length of the parabola's latus rectum, we need to find its focal length <em>f</em>. Luckily, since our equation is in vertex form, we can easily find from the focus (or focal point) coordinate, which is
where 
is called the focal length or distance of the focus from the vertex. So from our equation, we can see that the focal length <em>f</em> is
By definition, the length of the latus rectum is four times the focal length so therefore, its value is
