the opening in a rectangle door frame measures 9 feet by 3 feet. each of the doors described in the table measures 9 feet by 3 feet but have different diagonal lengths. which door will fit in the rectangular opening

Door 2

Step-by-step explanation:

To do this problem, we need to use the Pythagorean Theorem. The door is a rectangle and if we draw a line from corner to corner, we have right triangles.

To find the diagonal distance, we have to write and solve the equation below.

3^2 + 9^2 = c^2

9 + 81 = c^2

90 = c^2

c = the square root of 90

The square root of 90 can be simplified to 3 square roots of 10.

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
