Please help I will give brainliest to the right answer!!! A dolphin jumps out of the water, as shown. The function h = -16 + 26t models the height h (in feet) of the dolphin after t seconds. After how many seconds is the dolphin at a height of 5 feet? Round your answers to the nearest tenth.​

0.8 seconds

Step-by-step explanation:

Given function l:

h= -16 + 26t

where h represents height and t represents time.

The time for dolphin atbthe height 5 feet is given by putting the value of h as 5 in the function,

5 = -16 + 26t

5 + 16 = 26t

21 =26t

t = 21/26

t = 0.8

true

explanation:

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
