1 answer:
9514 1404 393
Answer:
(x y) = (1 2/3, 4 2/3)
Step-by-step explanation:
We're not sure the basis you're intended to use for estimating. Perhaps you're given a graph, or are intended to draw a graph. The attachment from a graphing calculator is able to tell us what the point of intersection is.
(x, y) = (1 2/3, 4 2/3)
__
The only "estimate" we need to make is that 0.667 ≈ 2/3.

Answer: Not safe
Step-by-step explanation:
Let the angle of elevation of the ramp be θ, then:
But the maximum angle for the ramp cannot exceed 7.1°. The calculated angle of elevation will make it difficult, if not impossible, for motorized wheelchairs to get up the ramp.
Therefore, the ramp at the local library is not safe for motorized wheelchairs
