Answer:
Step-by-step explanation:
Let the one of the side lengths of the rectangle be 
and the other be 
.
We can write the following equations, where will be the side opposite to the wall:
From the first equation, we can isolate 
and substitute into the second equation:
Therefore, the parabola 
denotes the area of this rectangular enclosure. The maximum area possible will occur at the vertex of this parabola.
The x-coordinate of the vertex of a parabola in standard form 
is given by 
.
Therefore, the vertex is:
Plug in 
to the equation to get the y-coordinate:
Thus the vertex of the parabola is at 
. This tells us the following:
- The maximum area occurs when one side (y) of the rectangle is equal to 25
- The maximum area of the enclosure is 1,250 square meters
- The other dimension, from
, must be 
And therefore, the desired answers are:
Answer:
A) 0 and 13
Step-by-step explanation:
64 - 37 = 27
27/2 = 13.5
13 teachers can teach 3 classes at max
The answer would be 3 and 2. Complementary means when you add two angles together, they equal 90° or a right angle.
7% of x = 450
0.07×x=450
x=450/0.07
x=6428.6 to the nearest tenth (one decimal place)
