Substitute the given side lengths into the equation for the Pythagorean Theorem

15 yards

Step-by-step explanation:

a^2 + b^2 = c^2

9^2 + 12^2 = c^2

81 + 144 = c^2

sqrt225 = c

c = 15 yards

power property.

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).
