An equation for estimating the speed of a tsunami is s=3.1√d where d is the depth of the ocean in meters and s is the speed in meters per second. find the depth of the ocean in meters when the speed of a tsunami is 250 meters per second. round your answer to the nearest tenth of a meter. a. 6503.6 b. 7523.7 c. 2402.5 d. 2231.4

  A.  6503.6

Step-by-step explanation:

Fill in the given number and solve.

  250 = 3.1√d

  250/3.1 = √d

  (250/3.1)² = d ≈ 6503.6 . . . meters . . . . matches selection A

I know it looks really complicated because of how much I wrote, I just wanted to make sure you knew why I did what I did and give some justification and key points when it comes to finding the slope. If you want me to explain how to do this in y=mx+b form I can do that too, just let me know:) the answers are(17.) -1 (19.) 7 (21.) 2.
