Answer:

y=x2 + 5

Step-by-step explanation:

A quadratic function is where the graph is in the shape of a "U" or parabola.

An example of a quadratic function if the form: y= ax^2+bx+c

What all formulas have in common is that at the end of the equation there will be a variable with no x paired with it( aka the y-intercept; the 'c' equivalent in the example formula i gave ), this letter is what tells the graph to move up or down the y-axis.

So in the answers given, ask yourself, " is there any y-intercept? And if so, is it plus 5?"

** plus 5 is the graph moving up 5 units on the y-axis

And you'd find the first answer is the only equation with a y-inter.

** side note: In y = (x + 5)^2, the 5 isn't a y-inter. bc it's inside the parenthesis. Numbers in the para. (like 5) tells the graph to move left or right ( if it is a "-" it's right and "+" is left)

You have to use PEMDAS, by multiplying before you add. So when you multiply 5*6, you get 30 and add the remaining 27 to get 57.

Answer:

$d=28.28$

Step-by-step explanation:

To calculate the lenght of the diagonal d across the square, we can assume that the square it is compound of two right triangles. So, we can resolve this exercise using The Pythagorean Theorem.

<em>The Pythagorean theorem</em> states that in every right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the respective lengths of the legs. It is the best-known proposition among those that have their own name in mathematics.

If in a right triangle there are legs of length a and b, and the measure of the hypotenuse is c, then the following relation is fulfilled:

$a^{2} +b^{2} =c^{2}$ a is the height, b is the base, and c is
