The function d = 4.9t2 represents the distance d, in meters, that a diver falls in t in seconds due to Earth’s gravity. Which equation represents the time, t, during a dive. How much time does it take for a cliff diver who is 185 meters above the water to reach the water below? Round to the nearest tenth.

A. t=d−4.92,13.4 s
B. t=d−4.9−−−−−−−√,12.1 s
C. t=d4.9−−−√,6.1 s
D. t=d4.9−−−√,1,421 s
Whats the answer?

Step-by-step explanation:

The given function is

Where is distance in meters and is time in seconds.

Let's isolate

Where

Therefore, the right answer is C. The time is 6.1 seconds, approximately.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
