The function,
A standard parabola with vertex at origin is represented as:
The above function is a standard parabola with vertex at origin and opening upward.
The vertex of the above function is at the origin and the value of
is 1.
Now, the function is translated 4 units up.
So, from the rule of function transformations, if a graph is moved up by units, then
units is added to the function.
Therefore,
.
Also, the vertex of will be translated 4 units up. So, the co-ordinates of the vertex of
will be
Now, express the above function in the vertex form .
We have
This gives,
Answer:
The length of the office is 36.4 ft
Step-by-step explanation:
The length of the classroom = 20 ft long
The length of the office = 20 ft + 82% of the classroom length
Now, 82 % of classroom length = 82 % of 20 ft
⇒
or, 82% of 20 ft = 16.4 ft
⇒The length of the office = 20 ft + 16.4 ft = 36.4 ft
Hence, the length of the office = 36.4 ft
