Joey built a skateboarding ramp. The base of the ramp along the ground is 13 feet, and the top of the ramp is 7 feet off the ground. What is the length of the ramp's incline?

14.77 feet

Step-by-step explanation:

Using the pythagoras theorem to get the length of the ramp

l² = 13² + 7²

l is the length of the ramp

l² = 169 + 49

l² = 218

l = √218

l = 14.77 feet

Hence the length of the ram is 14.77 feet

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
