Mohamed decided to track the number of leaves on the tree in his backyard each year. The first year, there were 500500500 leaves. Each year thereafter, the number of leaves was 40\%40%40, percent more than the year before. Let f(n)f(n)f, left parenthesis, n, right parenthesis be the number of leaves on the tree in Mohamed's back yard in the n^\text{th}n th n, start superscript, start text, t, h, end text, end superscript year since he started tracking it. fff is a sequence. What kind of sequence is it?

The sequence is a geometric sequence.

Step-by-step explanation:

The number of leaves in the tree in the first year is 500.

And the number of leaves in the tree in the second year increases by 40% of the number in the first year.

So, it will be

Again, the number of leaves in the tree in the third year increases by 40% of the number in the second year and so on.

Therefore, the number of leaves in the tree in the third year will be and so on.

If we want to calculate the number of leaves in the tree in the nth year by f(n) then it will be given by

Therefore, the sequence is a geometric sequence. (Answer)

Geometric sequence

f(1)=      500

f(n)=f(n-1)      x  1.4

Step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
