On a coordinate plane, a parabola opens up. It goes through (negative 3.25, 5), has a vertex of (1.7, negative 2.75), and goes t

Answer:

together they rake leaves in one minute.

Step-by-step explanation:

If Maya takes x minutes to rake, then in one minute, she rakes leaves.

For Carla, if her raking takes y minutes, in one minute she rakes leaves.

Thus, to find the amount they work together in one minute, we add both of their contributions for that minute, resulting in:

Finally, simplifying this expression gives:

As a result, they collectively rake leaves in a minute.

Using the Pythagorean theorem: In a right triangle where legs are labeled a and b, and hypotenuse is c. Given the triangle ΔXYZ has a right angle at Y, with angles YZX and ZXY both measuring 45 degrees, and ZY = YX = 12 cm. The task is to find the length of XZ.
