It’s just a quadratic function. If you’re trying to figure out if a parabola is a function just do a line test. Just look up function line test.

A parallelogram is shown below:
Marina CMI [18]
<h3>Answer:</h3>

A:  6 ft²

B:  3 ft² is the area of each of the two congruent triangles

<h3>Step-by-step explanation:</h3>

Part A. As with a rectangle, the area of a parallelogram is the product of base length and height.

  Area = (8 ft)·(3/4 ft) = 6 ft²

___

Part B. If you cut the area into two halves, each half will have half the area of the original. (That should not be a surprise.)

  triangle area = (6 ft²)/2 = 3 ft²

If the triangles are created by a diagonal across the original figure, each will have a base length and height that is the same as that of the original figure. The area of a triangle is half the product of base and height, so each triangle will have area ...

  triangle area = (1/2)bh = (1/2)(8 ft)(3/4 ft) = 3 ft²

The measure of an angle is two times the measure of a supplementary angle. what is the measure of each angle
lara31 [8.8K]
Let the angles be x and (180-x).

Let 2x = 180-x.

Then 3x = 180, and x = 60.  One angle is 60 degrees and the other is 180-60, or 120, degrees.
