I am having problem with this one you are going to help a neighbor build a ramp so he can easily go into his house in a wheel chair In order to meet federal guideline the ramp must not rise mor than 1 foot over a horizontal distane of 12 so would my answer be y x 12 - 1
To determine the necessary length of the ramp, you need to calculate the inclined distance (hypotenuse) using the Pythagorean theorem. The vertical rise will be 1 foot, and the horizontal distance will be 12 feet.
Here's how to calculate it step-by-step:
1. Square the vertical rise (1 foot) and the horizontal distance (12 feet):
1^2 = 1
12^2 = 144
2. Add the squares together:
1 + 144 = 145
3. Take the square root of the sum to find the hypotenuse:
√145 ≈ 12.042 feet
Therefore, the length of the ramp should be approximately 12.042 feet to meet the federal guidelines.
