If you would like to know the number of square feet of grass seeds that the lawn company can spread per hour, you can calculate this using the following steps:
7500 square feet ... 2 1/2 hours = 5/2 hours
x square feet = ? ... 1 hour
7500 * 1 = 5/2 * x
7500 = 5/2 * x /*2/5
x = 7500 * 2 / 5
x = 3000 square feet
The correct result would be 3000 square feet.
The answer here would be -3
Answer:
Option B is the correct option.
Step-by-step explanation:
We know that the vertex form of a quadratic's equation is generally expressed as
y = a(x - h)² + k
where (h, k) is called the vertex of the quadratic function
In our case, given the function

now comparing the equation with y = a(x - h)² + k
Here:
h = -3
k = 25/2
Therefore, the vertex of the function
is:
(h, k) = (-3, 25/2)
Thus,
The
form most quickly reveals the vertex.
Hence, option B is the correct option.
