Answer 1

Item 1 (2 points)
The student names two places where there are wheelchair ramps.
The student names one place where there are wheelchair ramps.
The student does not name any places where there are wheelchair ramps.
Item 2 (2 points)
The student provides the acceptable slope ratio for a wheelchair ramp and provides a clear explanation for what it means in a real-world context.
The student provides the acceptable slope ratio but does not clearly explain its meaning.
The student does not provide the acceptable slope ratio for a wheelchair ramp.
Item 3 (1 point) Not Applicable The student provides an image of a wheelchair ramp (with citation, if necessary). The student does not provide an image of a wheelchair rampk

Answer 2

Item 4 (2 points)
The student sketches the triangle and provides measurements for all three sides.
The student sketches the triangles but does not provide measurements for all three sides.
The student does not sketch the triangle.
Item 5 (2 points)
The student applies the converse of the Pythagorean Theorem. If it does not satisfy right triangle criteria, the student proceeds to explain why that is the case.
The student applies the converse of the Pythagorean Theorem. It fails to meet right triangle criteria, and the student does not provide an explanation.
The student does not apply the converse of the Pythagorean Theorem.
Item 6 (1 point)
Not Applicable The student correctly labels ∠A, the hypotenuse, and the adjacent and opposite legs on the triangle.
The student mislabels the triangle.

Answer 3

Item 7 (2 points)
The sine, cosine, and tangent ratios are all correctly identified for ∠A.
One or two of the sine, cosine, and tangent ratios are correctly identified for ∠A.
None of the sine, cosine, or tangent ratios are correctly identified for ∠A.
Item 8 (2 points)
The tangent ratio is correctly reduced. The student is able to use the ratio to explain whether or not the ramp is in compliance with the ADA.
The tangent ratio is correctly reduced, but the student is not able to explain whether the ramp is in compliance with the ADA. Alternatively, the tangent ratio is incorrectly reduced, but the student is able to clearly explain whether the incorrect ratio is in compliance with the ADA.
The tangent ratio is incorrectly reduced, and the student is not able to clearly explain whether the ratio is in compliance with the ADA.
Item 9 (1 point)
Not Applicable The student finds the measure of ∠A using inverse tangent and shows work.
The student does not find the measure of ∠A.

Answer 4

u still need help?

Answer 5

The student clearly explains in at least two sentences how mathematics is used to measure whether or not a wheelchair ramp complies with the ADA.
The student attempts, but is unable to clearly explain the role mathematics plays in determining whether or not a wheelchair ramp complies with the ADA.
The student’s response is either not present or irrelevant to the task.

Answer 6

yes

Answer 7

is it the first response or the one u just put on here?

Answer 8

what is the question exactly?

Answer 9

all of it im kinda confused its
Lesson 4: Angles of Elevation and Depression

Geometry B Unit 2: Right Triangles and Trigonometry (if that helps)

Answer 10

yeah so what is it that u r supposed to do?

Answer 11

i guess this Directions: The ADA (American with Disabilities act) requires specific building codes for wheelchair ramps. This applies to both businesses and home construction. For this portfolio entry you will research and investigate wheelchair ramps and their connections to Geometry and Trigonometry. 1. Name at least two places in your community where you have seen wheelchair ramps. 2. Research the ADA’s requirements for wheelchair ramps. What is the acceptable slope ratio for a wheelchair ramp? Explain, in your own words, what this ratio means. 3. Find a wheelchair ramp either online or in your community. You can take a picture of one (state where your wheelchair ramp is from) and paste it in your portfolio. If you find one online, make sure to cite from where you are taking the picture. 4. Sketch over the right triangle formed from your wheelchair ramp and the ground. Include the lengths of each side of the triangle in your sketch. 5. Use the Converse of the Pythagorean Theorem to verify that the measurements of your wheelchair ramp are consistent with those of a right triangle (Hint: Show that ). Show all work. If the measurements are not consistent, explain why you think this may be. 2 2 2c ab = + 6. Label the angle formed between the ground and the wheelchair ramp ∠A. Write hypotenuse along the hypotenuse, adjacent side along the leg adjacent to ∠ A, and opposite leg along the leg opposite of ∠A. 7. Write the sine, cosine, and tangent ratios for ∠A. 8. Reduce the tangent ratio of ∠A. Is this ratio in compliance with the building code slope ratio for wheelchair ramps? Explain why or why not. 9. Find the measure of ∠A using inverse tangent. Show all work. 10.In conclusion, explain in at least two sentences how mathematics plays an important role in making sure ramps are safe and easy to use.

Answer 12

i have no ides i dont live in ur area... google it... just put like for the first one put... two places in "where u r from" where you have seen wheelchair ramps
