Adiver when 25.65 feet below the surface of the ocean, and then 16.5 feet further down, he then rose 12.45 feet. write and solve an expression to find the driver's new depth.

The expression is:

-25.65 + (-16.5) + 12.45 = -29.7

Therefore, the divers new depth is -29.7 (or 29.7 feet below the surface)

Hope this helps

X= 25.65 + 16.5 - 12.45

X=29.70

(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
