in the formula, I is the purchase price, in dollars, of the automobile and the expression (1−d)n is known as the decay factor. A car purchased for $21,000 has a decay factor of 0.7. What is the rate of depreciation of the vehicle?

where is the picture

step-by-step explanation:

2: 10

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

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
