Answer:

The distance d is 16.583 meters ( approx )

Step-by-step explanation:

Here, r represents the length of the drawbridge, p represents the point above the roadway and d represents the distance d,

Let h be the distance of point P above the roadway,

Hence, the function that shows the given situation,

R=\sqrt{h^2+d^2}

Here, r = 18 meters, h = 7 meters,

\implies 18=\sqrt{7^2+d^2}

\implies 324 = 49+d^2

\implies 275=d^2\implies d=16.5831239518\approx 16.583\text{ meters}

Thus, The distance d is 16.583 meters ( approx )

Answer:

so does this go with what you got I would think C correct me if i'm wrong

Step-by-step When a population or group of something is declining, and the amount that decreases is proportional to the size of the population, it's called exponential decay. In exponential decay, the total value decreases but the proportion that leaves remains constant over time.
