Answer:

A tiny guess, but I believe the answer is 63.

Explanation:

Well, since Mark would’ve had the 4 in the 4:3, that would mean each part would be 9 dollars.

So, if there seven parts in total, that would mean it’s...

Write an equation of the line in slope-intercept form​
andre [41]

Answer:

y = 6

x = 3

Step-by-step explanation:

To find y and x on a graph, you must count how many squares one dot intercepts the same line as the other dot (in this case it's three) and for the y axis you do the ssme thing; find out how many squares are between both dots between the point where they intercept each other but for this time, it's vertically (in this case it's 6)

svetlana [45]

Answer:

The required recursive formula is

f(n)= 500\times(1.4)^{n-1}\\

Step-by-step explanation:

Mohamed decided to track the number of leaves on the tree in his backyard each year.

The first year there were 500 leaves

Year \: 1 = 500

Each year thereafter the number of leaves was 40% more than the year before so that means

Year \: 2 = 500(1+0.40) = 500\times 1.4\\

For the third year the number of leaves increase 40% than the year before so that means

Year \: 3 = 500\times 1.4(1+0.40) = 500 \times 1.4^{2}\\

Similarly for fourth year,

Year \: 4 = 500\times 1.4^{2}(1+0.40) = 500\times 1.4^{3}\\

So we can clearly see the pattern here

Let f(n) be the number of leaves on the tree in Mohameds back yard in the nth year since he started tracking it then general recursive formula is

f(n)= 500\times(1.4)^{n-1}\\

This is the required recursive formula to find the number of leaves for the nth year.

Bonus:

Lets find out the number of leaves in the 10th year,

f(10)= 500\times(1.4)^{10-1}\\\\f(10)= 500\times(1.4)^{9}\\\\f(10)= 500\times20.66\\\\f(10)= 10330

So there will be 10330 leaves in the 10th year.
