Write an expression illustrating the total vertical distance the dolphin traveled from the spot it was first sighted, according to the observations. Simplify the expression to find the total vertical distance the dolphin traveled.

hello your question lacks some information hence I will provide a more general answer

answer :

The expression is ;  D = a + ar

Step-by-step explanation:

An expression illustrating the total vertical distance travelled by a body from rest ( "spot it was first sighted" ) as quoted in the question. can be written as

D = a + ar

where D = Total vertical distance travelled

           a = start term ( initial height )

           r = common ratio

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

correct answer is b. 27/8
