Abungee jumper falls from a bridge 400 feet above ground. her height above ground after t seconds is given by the equation where h is the height of the jumper in feet and t is the time in seconds since her jump. approximately how long will it take for the bungee jumper to reach 100 feet above the ground on her initial jump?

B. 4.3 seconds.

Step-by-step explanation:

1. You must substitute h=100 into the equation given in the problem and solve for the time, as you can see below:

3. Then, it will take 4.3 seconds for the bungee jumper to reach 100 feet above the ground on her initial jump. Therefore,  the answer is the option B.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
