Answer:

36 ft²

Step-by-step explanation:

If BE = 3√2 ft, then the diagonal BD is 6√2 ft. The area of the square (as with any rhombus) is half the product of the diagonals. Since both diagonals are the same length, the area of the square is ...

area = 1/2·(6√2 ft)² = 36 ft²

The area of the square is 36 square feet.

_____

You may be expected to find the length of one side of the square using the Pythagorean theorem.

AB² = AE² + EB² . . . . . = the area of the square

AB² = (3√2 ft)² +(3√2 ft)² = 18 ft² + 18 ft²

AB² = 36 ft² . . . . . . . . . the area of the square

What are the slope and the y-intercept of the linear function that is represented by the graph?

enyata [817]

The slope and the y-intercept of the linear function represented by the graph is given as follows:

The slope is two-thirds, and the y-intercept is –2.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Looking at the graph, when x = 0, y = -2, hence the y-intercept is of -2. The slope is given by <u>change in y divided by change in x</u>, hence considering that the graph also goes through (3,0), it is given by:

$m = \frac{0 - (-2)}{3 - 0} = \frac{2}{3}$
