<h3>
What is the general form of a quadratic equation?</h3>
The general form of the quadratic equation is given by;

Where; a, b, and c are the constants.
x; 0 1 2 3 4 5
y; 2.82 3. 29 3. 46 3. 33 2. 88 2. 24
From the table when the value of x = 0 the value of y is 2.82.
Then,

From the table when the value of x = 3 the value of y is 3.33.

From the table when the value of x = 5 the value of y is 2.24.

And the value of b is;

Therefore,
The quadratic regression equation for this data set is;

Hence, the quadratic regression equation for this data set is
.

Step-by-step explanation:

Answer:
m = 5
Step-by-step explanation:
We are told that the two triangles are similar. Thus, each side of the larger triangle is the same multiple of the corresponding side in the smaller triangle.
Thus, 12 = k(7.2), where k is the constant of proportionality.
Solving this for k, we get
k = 12/7.2 = 1 2/3
Thus, side m is 1 2/3 times 3, or 5/3 times 3, or just 5.
m = 5
