Which equation has a graph that is a parabola with a vertex at (–2, 0)?
2 answers:
Answer:
The vertex of a quadratic equation corresponds to the point where the maximum or minimum value is located.
If the function has a positive leading coefficient, the vertex corresponds to the minimum value.
If it has a negative leading coefficient, the vertex corresponds to the maximum valuevalue
If the vertex is located at
(–2, 0)
The possibilities are
y = (x-2)^2
or,
y = - (x-2)^2
Since the problem tells us the answer, we adopt the positive values
Answer:
y = (x-2)^2

Answer:

Step-by-step explanation:
A graph that is a parabola with a vertex at (–2, 0)
Vertex form of parabola equation is

where (h,k) is the vertex
WE are given with vertex (-2,0)
(-2,0) is (h,k)
h=-2 and k=0
Plug the value in vertex form of equation. Lets take a=1

Equation becomes

MQ : QN = 2 : 5
MQ : QN = LP : PN
2 : 5 = 3 : PN
That means PN = 15/2
Answer:
Surface area of sphere = 4πr²
r = radius
and radius = diameter/2
radius = 13/2
= 6.5cm
Surface area = 4 × π × 6.5
= 26 × π
= 81.68
= 81.7cm²

Answer:
C. 4.3
Step-by-step explanation:
Given that
n = 17
P = 1/4
Using binomial
Mean = np
Mean = 17 × (1/4)
= 17 × .25
= 4.25
Approximately = 4.3
I think it’s C but it could be D.. i would go with C tho
