mutipication
Step-by-step explanation:
Given:
The quadratic equation is

To find:
The vertex of the given quadratic equation.
Solution:
If a quadratic function is
, then

We have,

It can be written as

...(i)
Here,
.



Putting
in (i), we get
On further simplification, we get
So, the vertex of the given quadratic equation is
.
Therefore, the correct option is A.
Answer:
The square lawn.
Step-by-step explanation:
This is because a perimeter of 36 meters means that it is 81 ft^2 of total area.

r, which would be smaller that 81 ft^2.
You never showed the triangle
The answer is:
(null hypothesis) u=2.7; Ha(alt hypothesis): u<2.7
