Your town’s public library is building a new wheelchair ramp to its entrance. by the law, the maximum angle of incline for the ramp is 4.76°. the ramp will have a vertical rise of 2 ft. what is the shortest horizontal distance that the ramp can span? a.) 15.3ft b.) 3.5 ft c.) 24.0 ft d.) 9.5 ft

Use trigonometry to find the ramp distance.

sin(4.76°) = 2/r

Let r = ramp distance in feet

r = 2/sin(4.76°)

r = 24.1015718106

Round off to the nearest foot.

Doing so we get r = 24 feet.

The ramp is 24.0 feet long.

Choice C

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
