<span> we have that
standard form of equation for parabola:
(x-h)^2=-4p(y-k)
(h,k) --------->being the (x,y) coordinates of the vertex.
Parabola opens downwards because focus is below vertex on the axis of symmetry.
For given problem:
</span><span>vertex: (-3,2)
axis of symmetry: x=-3
p=distance from vertex to focus on the axis of symmetry=2-(-1)=3
4p=12
Directrix: y=2+p=5
Equation:
(x+3)^2=-12(y-2)
the answer is </span>(x+3)^2=-12(y-2)
Look it up on the internet youll find the answer there i am only learining about adding integers right now
Answer:
0.021/yr or 2.1%/yr
Step-by-step explanation:
Find the quotient:
$36.75/$36.00
This comes out to 1.021,
so the inflation rate is 1.021 - 1.000 = 0.021 or 2.1%/year
Answer: No. both are independent quantity. Therefore, the number of books purchased does not affect the value of m.
Step-by-step explanation:
Given: Julio and his sister bought 8 books and m magazines for $1 each.
The amount of money that Julio spent is represented by the expression 1/2(m+8)
Thus, the amount she and her sister will pay is dependent on the number of books and the number of magazines, but the number of magazines and the number books are independent quantity.
Therefore, the number of books purchased does not affect the value of m.
I believe its C because they distribute instead of reverse like A would be
