Answer: (-3,-6)
Step-by-step explanation:
Thank you for posting the figure. Without it, I would have thought the parabola has a vertical axis.
For a parabola with a horizontal axis (as in this case), the equation of the parabola is
f(y)=a(y-k)^2+h
where (h,k) is the vertex.
Substituting (h,k)=(2,-4),
f(y)=a(y+4)^2+2...................(1)
as the equation of the parabola, with the value of "a" yet unknown.
Since we are given that the parabola passes through the point (-3,-3), we can substitute the corresponding x,y values in (1) to solve for a.
f(y)=-3=a(-3+4)^2+2
solve for a
a=(-3-2)/(1^2)=-5
So the equation of the parabola is f(y)=-5(y+4)^2+2
Answer:
20 and 40
Step-by-step explanation:
120/2=60
3x=60
x=20
20x2=40 since it is two times
Well it's definitely not 2 groups because it is an odd number.
It is not 4 groups because that would be 87.5
It is not 6.
Your answer is d.9. 351/9=39
The measurement of ADB is 218 degrees. How I got this is that AD is 128 degrees plus AB which is 90 degrees because of the square at the bottom, meaning that it is a right triangle. This equaling 218 degrees.
