Choose the definition for the function. <br> Please help me!!!
Zina [86]

Answer:

The answer is B

Step-by-step explanation:

1)

These are in Y = MX + B form

The first line has a positive slope, so the coefficient "M" is positive.

The second line has a negative slope, so the coefficient "M" is negative.

2)

The first line has a filled in dot at Y = 2.

Since it's to the left (less than X direction)...

X <= 0

The second has an empty circle at Y = 4.

Since the line goes to the right....

0 < X

3)

Also, the "+2" and the "+4" in the equation as the "+ B" indicates where each line will cross the Y axis.

From these things, we can infer that B is the correct answer.

Answer:

A  = 222 units^2

Step-by-step explanation:

To find the area of this trapezoid, first draw an imaginary horizontal line parallel to AD and connecting C with AB  (Call this point E).  Below this line we have the triangle CEB with hypotenuse 13 units and vertical side (21 - 16) units, or 5 units.  Then the width of the entire figure shown can be obtainied using the Pythagorean Theorem:

(5 units)^2 + CE^2 = (13 units)^2, or 25 + CE^2 = 169. Solving this for CE, we get |CE| = 12.

The area of this trapezoid is

A = (average vertical length)(width), which here is:

       (21 + 16) units

A  = --------------------- * (12 units),   which simplifies to:

                  2

A = (37/2 units)(12 units)  =  A  = 37*6 units  =  A  = 222 units^2
