the lowest point of the dry lake bed in the example has an elevation of -18 3/4ft. What number represents the change in the elevation from the start of the path to the lowest point in the dry lake bed? Show your work

i'm not really sure how to answer that

step-by-step explanation:

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week

your answer is b.

1,333 cubic feet  

and i know this one is right.

d: 0.7(t + 4 + 2) = t .
